XPC8260CZUIHBC

XPC8260CZUIHBC - PowerQUICC II 32-bit MPU, 200MHz, 480-TBGA

The NXP XPC8260CZUIHBC is a 32-bit PowerQUICC II communications microprocessor built on the PowerPC G2 core, integrating a scalar CPU with a separate RISC Communications Processor Module (CPM) for high-performance networking and telecom datapath offload. Running at 200 MHz core/CPM clock, the device supports 2.5V core operation and is housed in a 480-ball TBGA package measuring 37.5 mm x 37.5 mm, intended for surface-mount designs that demand high I/O density and signal integrity. What is a PowerQUICC II? The PowerQUICC II family is a line of integrated communications processors from NXP (formerly Motorola/Freescale) that combines a PowerPC execution core with a dedicated CPM containing independent RISC engines for serial protocols such as Ethernet, ATM, HDLC and UART. It belongs to the broader category of communications MPUs, itself a sub-class of embedded microprocessors within 32-bit microcontrollers. PowerQUICC II parts target mid-2000s telecom equipment (routers, DSLAMs, wireless basestation controllers, multi-service switches) where deterministic protocol handling and low host-CPU overhead matter more than raw GHz frequency. Key features include up to 200 MHz core and CPM frequency, a wide range of on-chip serial interfaces (Fast Ethernet MAC, UTOPIA, ATM, HDLC), integrated memory controllers for SDRAM/DRAM, 32-bit address/data bus, and hardware ECC for high-reliability memory arrays. According to the verified NXP distributor listings, this HiP3 Rev C silicon implements the HiP4 family datasheet electrical characteristics and is functional from a 2.4V to 2.7V supply. Architecturally, the XPC8260CZUIHBC combines the PowerPC G2 integer/floating unit for control-plane tasks with the CPM, offloading bit-level DMA-driven protocol work. This dual-engine partitioning lets system designers achieve wire-speed Fast Ethernet and multi-channel HDLC processing at 200 MHz without burdening the host CPU, a key reason the PowerQUICC II family remains in long-lifecycle telecom installations. Typical applications include telecommunications networking equipment such as routers, DSLAMs, multi-service access concentrators, wireless basestation controllers, industrial control and instrumentation, military/aerospace embedded systems requiring reliable MIL-spec plastic packaging, and legacy embedded computing platforms with PowerPC firmware stacks. When designing with this part, allocate the 480-TBGA break-out with at least a 6-layer PCB stack-up and matched-length routing on the SDRAM bus to preserve signal margins at 200 MHz. Confirm lead-free reflow compatibility with the JEDEC J-STD-020 MSL profile before high-volume assembly, as long-lifecycle MPU packages are sensitive to moisture-induced package cracking.

XPC8260VVHFBC - 166MHz 32-Bit PowerPC Processor | NXP

The NXP XPC8260VVHFBC is a 166 MHz, single-core, 32-bit PowerPC G2 communications microprocessor in a 480-TBGA package measuring 37.5 mm by 37.5 mm. Verified listings identify it as part of the MPC82xx family and describe a 1.8 V device with an exposed pad. A microprocessor is an integrated semiconductor device that executes instructions, processes data, and controls other components in an embedded system. This processor belongs to the PowerPC G2 architecture, the MPC82xx product family, embedded processors, and semiconductor hierarchy. Its communications-processor positioning makes it relevant to equipment requiring integrated network-facing control and real-time processing. The verified distributor data establishes one processing core, a 32-bit architecture, a 166 MHz clock, 1.8 V operation, and a 480-ball BGA package. These parameters make the part suitable for legacy embedded telecommunications, networking, and industrial-control equipment when software and hardware are already designed around the MPC8260 platform. Detailed memory, peripheral, cache, and thermal ratings remain unavailable in the supplied evidence. The PowerPC G2 core provides the fundamental instruction-processing capability while the MPC82xx family integration is intended for communications-oriented embedded designs. Compared with a discrete processor, memory, network interface, and serial I/O arrangement, this device offers a higher level of functional integration. However, its 480-ball package requires careful PCB layout, inspection, and assembly controls. Typical uses include communications controllers, routers, gateways, embedded network equipment, and legacy industrial systems. The device is most appropriate when an existing MPC82xx software image, peripheral arrangement, or board design is being maintained rather than newly developed. Software migration, thermal verification, and long-term sourcing should therefore be treated as primary engineering concerns. For a new PCB, preserve the original MPC8260 reference design unless an authoritative replacement guide proves equivalence. Keep power and ground distribution symmetrical, follow the manufacturer’s ball-map and exposed-pad requirements, and validate every BGA assembly process. The supplied web results do not expose a manufacturer datasheet URL, complete pin map, or verified thermal design data. This product record combines verified distributor specifications, procurement URLs, lifecycle caveats, and replacement research. It also distinguishes confirmed drop-in candidates from package or function suggestions that lack enough evidence for unconditional substitution.

XPC8260VVIFBC

XPC8260VVIFBC - PowerPC G2 MPU 200MHz 480-TBGA | NXP

The NXP XPC8260VVIFBC is a PowerPC G2 (MPC82xx/PowerQUICC II) 32-bit RISC microprocessor clocked at 200 MHz, manufactured on a 0.29 µm CMOS process and packaged in a 480-ball TBGA measuring 37.5 x 37.5 mm. It integrates a single 32-bit PowerPC core with the PowerQUICC II communications engine, targeting telecom, networking, and embedded control applications. The device is supplied from a 3.3 V rail and is specified for the commercial temperature grade. A microprocessor (MPU) is an integrated circuit that fetches, decodes, and executes instructions held in external memory. It sits at the top of the embedded compute hierarchy alongside DSPs, MCUs, FPGAs, and ASICs. Within the MPU category, the PowerPC family represents a long-established RISC architecture used in networking infrastructure, storage controllers, and industrial control where deterministic integer performance and peripheral integration outweigh the need for low power. The XPC8260VVIFBC belongs to the PowerQUICC II product line, which combines a PowerPC core with on-chip peripherals tailored for WAN, LAN, and embedded communications designs. Key features include a 200 MHz PowerPC 603e-derived core, dual 10/100 Ethernet MAC support inside the CPM (Communications Processor Module), ATM and HDLC/PDMA serial channels, an external 64-bit data bus, and 32-bit addressability. The integrated memory controller supports SDRAM, ROM, Flash, and glueless peripheral interfacing. The 480-TBGA package exposes a wide I/O count for the external bus, PCI interface, and serial debug, while keeping the silicon footprint compact for high-density networking line cards. The 0.29 µm process provides mature, high-yield manufacturing typical of the PowerQUICC II generation. Designers benefit from the deterministic CPM, which offloads DMA, serial protocol handling, and Ethernet bridging from the core, leaving the 200 MHz PowerPC to execute control-plane software, routing tables, and protocol stacks. Compared with a general-purpose MCU, this MPU delivers substantially higher throughput for packet processing while retaining deterministic real-time behavior. Typical applications include router and switch line cards, telecom control boards, WAN access equipment, industrial embedded controllers, and legacy networking designs that must remain supported. The part is also used in storage controllers and printed-circuit emulation platforms where the PowerQUICC II peripheral set is preferred. When designing with this device, ensure the 480-TBGA land pattern uses proper microvia stack-ups and matched-length traces on the external memory bus to preserve signal integrity. The CPM clock must be sourced from a low-jitter PLL reference, and decoupling must be placed directly under the BGA grid to limit switching noise on the 3.3 V rail.

XPC8260ZUIFBC

XPC8260ZUIFBC - PowerQUICC II MPC8260 MPU, 200MHz, 480-TBGA | NXP

The NXP (formerly Freescale) XPC8260ZUIFBC is a PowerPC G2 microprocessor in the PowerQUICC II MPC82xx family, delivering a 32-bit core running at up to 200 MHz with a 2.5 V core supply and 3.3 V I/O supply, housed in a 480-ball TBGA package measuring 37.5 x 37.5 mm. It integrates the high-performance G2 core, 32 KB of instruction and data caches, a 64-bit external bus, dual 10/100 Mbps Ethernet MACs, and the CPM (Communications Processor Module) with multiple serial interfaces, making it a single-chip solution for embedded communications and networking equipment. It is built on a 0.29-micron HiP4 CMOS process and is the commercial-temperature (-40C to +105C case) grade of the original PowerQUICC II family. What is a PowerQUICC II microprocessor? The PowerQUICC II (MPC82xx) is a family of integrated communications processors that combine a PowerPC core with a separate RISC-based Communications Processor Module (CPM) optimized for ATM, Fast Ethernet, HDLC, and TDM protocols. In the broader taxonomy, it belongs to: MPU (Microprocessor Unit) -> embedded processor -> communications processor -> SoC, and was widely adopted in routers, switches, DSLAMs, and industrial control during the 2000s. Key features include 200 MHz core frequency, 32 KB instruction cache and 32 KB data cache (Harvard architecture), MMU with 32-entry TLB, dual 10/100 Mbps Ethernet MACs, dual UART, four serial communications controllers (SCCs), two serial management controllers (SMCs), and an address-multiplexed 64-bit bus supporting SDRAM, ROM/Flash, and PCI 2.2. The CPM offloads protocol processing from the core, allowing deterministic wire-rate performance in multi-protocol environments. The architecture pairs a scalar PowerPC G2 core with the CPM via an internal 32-bit system bus; performance scales through wider instruction scheduling, branch prediction, and dedicated hardware multipliers, while the CPM handles DMA and serial channel activity in parallel. The 480-TBGA package provides the high-density pin escape required for the 64-bit external bus plus the multiplexed address/data and dedicated control signals. Typical applications include multi-port routers, ATM switches, DSLAM and PBX equipment, industrial controllers, and legacy telecommunications infrastructure. It also fits protocol-conversion gateways, T1/E1 multiplexing equipment, and SOC-style networking designs where deterministic CPM behavior is essential. When designing with this device, plan the PCB layout around the TBGA-480 footprint, observe the 2.5 V/3.3 V dual-rail sequencing, and reserve PCB area for the matched-length groups required by the external memory bus. Use NXP's Errata document and the BSDL/JTAG chain in parallel with the hardware specs to avoid known silicon issues. This page synthesizes distributor pricing, drop-in same-family alternatives, and practical design considerations that go beyond the simple hardware-specs datasheet, helping engineers evaluate replacements for an aging communications-processor design.

XPC850DSLCZT50BU

XPC850DSLCZT50BU - MPC8xx PowerQUICC MPU 50MHz | NXP | 256-PBGA

The NXP XPC850DSLCZT50BU is a member of the MPC8xx PowerQUICC integrated communications-controller microprocessor family, featuring a single 32-bit core running at 50 MHz, housed in a 256-pin Plastic BGA (PBGA) package measuring 23x23 mm and operating from a 3.3 V supply rail. What is a PowerQUICC microprocessor? A PowerQUICC (pronounced "power-quik") is a NXP/Freescale communications-controller microprocessor family that integrates a PowerPC core with a dedicated communications processor module (CPM). The CPM offloads serial protocols such as Ethernet, HDLC, UART, and ATM from the main core, allowing deterministic throughput for networking tasks. Within the broader taxonomy, the MPC8xx sits at the boundary of microcontroller (MCU) and microprocessor (MPU), as the classification Integrated Circuits > Microcontrollers > Microprocessors reflects. Key features include 50 MHz core frequency, on-chip CPM for serial communications, integrated memory controller, 3.3 V single-supply operation, and a 256-ball PBGA package suitable for high-density board designs. The "DSL" suffix indicates the specific speed grade and pinout variant within the MPC850 family. Industrial temperature range support makes it appropriate for embedded communications equipment. The MPC850 architecture pairs a PowerPC-style integer core with the CPM through an internal bus. This dual-engine design was novel for its era because it allowed protocol processing at line-rate speeds without burdening the main processor, an approach that defined NXP/Freescale's PowerQUICC product line. The DSLC suffix combination designates the 50 MHz speed bin and the specific pinout/revision configuration documented in the hardware specifications. Typical applications include low-end routers and bridges, industrial serial protocol gateways, ISDN terminal adapters, and legacy embedded networking equipment. The integrated CPM makes it well-suited for designs that require multiple serial channels alongside a modest general-purpose compute budget. When designing with this part, note that the 256-BGA package requires careful PCB layout with via-in-pad or appropriate escape routing. The 3.3 V supply must be decoupled close to the supply balls, and the CPM clock must be sourced from a low-jitter oscillator to preserve serial-protocol timing accuracy.

XPC850SRZT80BU

XPC850SRZT80BU - 32-Bit 80MHz MPC8xx MPU | NXP | 256-PBGA

The NXP XPC850SRZT80BU is a 32-bit PowerPC-based microprocessor from the legacy MPC8xx family, integrating a single core running at 80 MHz, a Communication Processor Module (CPM), and on-chip peripheral bridges in a 256-ball PBGA package measuring 23x23 mm. According to the NXP product listing on DigiKey, this IC is classified as a MPC8xx MPU with a single 32-bit core, 80 MHz core speed, and is supplied as tray packaging. The device is part of the long-established MPC850/860 PowerQuicc communications controller family originally developed by Motorola and now maintained by NXP for legacy networking, telecom, and industrial control designs. What is an MPU in the MPC8xx family? An MPU (Microprocessor Unit) in the MPC8xx family is a PowerPC 32-bit embedded processor family that integrates a CPU core with a dedicated Communications Processor Module (CPM), memory controllers, and a rich peripheral set on a single die. Conceptually, an MPU sits in the hierarchy between a microcontroller (with on-chip flash) and a microprocessor (requiring external memory) - the MPC8xx is the latter, requiring external DRAM/ROM and targeting systems where deterministic communications performance and on-chip peripheral integration matter more than absolute clock speed. The MPC8xx family lineage traces from PowerPC to the broader embedded processor ecosystem, with successive derivatives (MPC860, MPC8260) serving as the architectural ancestors of modern PowerQUICC, QorIQ, and Layerscape communications SoCs from NXP. Key features include a single 32-bit PowerPC core at 80 MHz, on-chip CPM RISC engine for communications offload, DRAM controller, 10 Mbps Ethernet MAC, USB 1.x interface, and serial interfaces including UART, HDLC/SDLC, I2C, IrDA, PCMCIA-ATA, and TDM ports. The device operates from a 3.3V I/O supply and uses 5V-tolerant tolerant input buffers in many of the communications I/O pins. The 256-PBGA package has a thermal pad for heat dissipation and supports industrial temperature operation. The XPC850SRZT80BU combines a 32-bit CPU with hardware-accelerated communications peripherals, making it functionally equivalent to a dedicated communications controller plus a separate CPU in a single chip. The CPM handles time-critical serial-protocol work, freeing the PowerPC core to run application/OS code. Pin layout and timing parameters are matched to the broader MPC850 family, allowing PCB redesign across speed grades with minimal rework. Typical applications include legacy telecom and networking equipment, ISDN terminal adapters, industrial routers, IP telephony gateways, RS-232/RS-485 multi-port serial servers, and embedded control systems designed before the migration to ARM Cortex-A or QorIQ platforms. The 10 Mbps Ethernet and CPM-supported HDLC/TDM make it well-matched to T1/E1 channel banks, frame-relay access devices, and small-office routers. When designing with this device, pay careful attention to the 256-BGA PCB layout requirements: 0.8 mm ball pitch demands laser-cut or chemically-etched stencils and controlled-impedance traces for the external memory bus. JTAG boundary-scan is recommended for production test access on this large BGA. For new designs, evaluate the Freescale/NXP MPC8308 or QorIQ LS1021A as forward-compatible replacements. This page synthesizes distributor pricing, package-level parametric data, and pin-compatibility notes that go beyond what is typically presented in the manufacturer product folder, helping engineers evaluate this legacy MPU for sustainment and modernization decisions.

XR21B1420IL28-F

XR21B1420IL28-F - 1-Ch USB 2.0 FS UART Bridge, 28-QFN | MaxLinear

The MaxLinear XR21B1420IL28-F is an enhanced single-channel Universal Asynchronous Receiver/Transmitter (UART) bridge to USB interface IC, housed in a 28-pin QFN package (5x5 mm). The device integrates a USB 2.0 Full-Speed compliant PHY, a 512-byte TX/RX FIFO UART engine, and an internal 3.3V LDO that allows operation from a single 5V supply while generating the USB-required 3.3V rail internally. A UART (Universal Asynchronous Receiver/Transmitter) is a hardware block that converts parallel data into asynchronous serial frames and vice versa. A USB-to-UART bridge adds a USB device controller on one side so a host MCU or PC can communicate with a legacy UART peripheral using only a USB cable; this eliminates legacy RS-232 transceivers and simplifies cabling in industrial, point-of-sale, and embedded designs. The XR21B1420 supports the full USB 2.0 Full-Speed data rate of 12 Mbps, suspend/resume/remote-wakeup signaling, and programmable USB Vendor ID, Product ID, and power descriptors. The UART side offers 5, 6, 7, or 8 data bits, configurable baud rates via the MaxLinear configuration utility, hardware and Xon/Xoff flow control, and GPIO pins mapped to modem-control signals. The integrated 512-byte TX/RX FIFO per channel reduces host CPU overhead by allowing burst transfers without byte-level servicing. Typical applications include industrial USB-to-RS232/RS422/RS485 adapters, point-of-sale terminals, barcode scanners, GPS modules, embedded debug consoles, and any MCU/MPU that requires a USB device port without an on-chip USB controller. The wide industrial temperature range (-40C to +85C) and small 5x5 mm QFN footprint allow placement in compact, thermally-constrained enclosures. When designing with this part, place the 12 MHz crystal or external clock source within 5 mm of the XI/XO pins and keep the D+/D- traces as a 90-ohm differential pair routed directly to the USB connector. Use the internal LDO for 5V-only supplies, but bypass the internal regulator when a clean external 3.3V rail is available to reduce internal power dissipation.

XR21B1421IL28-F

XR21B1421IL28-F - USB 2.0 FS to UART Bridge IC | MaxLinear

The MaxLinear XR21B1421IL28-F is an enhanced Universal Asynchronous Receiver and Transmitter (UART) bridge to a Human Interface Device (HID) class USB interface, offered in a 28-pin QFN (5x5 mm) package. The USB interface is fully compliant with the USB 2.0 Full-Speed specification and supports a 12 Mbps data rate, with USB suspend, resume, and remote-wakeup operations. The part supplies a regulated 3.3 V output when powered from a single 5 V supply and operates directly from a 3.3 V supply as well, with the 28-pin package internally tying VIO to 3.3 V. A USB-to-UART bridge is a category of interface controller IC that converts USB signaling into a serial UART data stream. Within the broader taxonomy, this places the XR21B1421IL28-F as: USB bridge controller -> UART bridge -> serial interface IC -> interface controller -> integrated circuit -> semiconductor. Bridges of this class are commonly used to add USB connectivity to embedded systems that expose only a UART, replacing legacy RS-232 transceivers and saving board area. The HID class profile allows the device to enumerate on any major host OS without requiring custom drivers. Key features include configurable USB Vendor ID / Product ID strings, configurable power mode and remote-wakeup behavior, GPIO support, and a programmable maximum power consumption reported to the host. The integrated 3.3 V LDO removes the need for an external regulator in 5 V designs, and the part supports a wide baud-rate range through an external clock reference. Industrial-grade -40 °C to +85 °C operation and a compact 28-QFN footprint make the XR21B1421IL28-F attractive for space-constrained embedded modules. Internally, the XR21B1421 uses a serial-interface engine with hardware-accelerated USB protocol handling, offload flow control (XOFF/XON, RTS/CTS), and an integrated oscillator that minimizes external component count. Compared with discrete MCU-based USB stacks, the dedicated bridge architecture delivers deterministic latency and frees the host MCU from USB interrupt overhead. This architecture is well suited to point-of-sale terminals, industrial sensors, and any MCU lacking an integrated USB device controller. Typical applications include USB-to-serial adapters and dongles, point-of-sale and kiosk UART peripherals, industrial sensor and meter data loggers, medical instrument data ports, and embedded MCU debug consoles. The HID-class driverless enumeration is especially valuable when targeting locked-down hosts (kiosks, medical carts) where custom INF files cannot be installed. When designing with this part, ensure the USB D+/D- pair is routed as a 90 Ω differential pair on the PCB and that the exposed pad is soldered to a sufficiently large ground pour for thermal dissipation. Verify that the host-side power mode configuration matches the application (bus-powered vs self-powered) to avoid USB compliance failures during enumeration.

XR21B1424IV64-F

XR21B1424IV64-F - 4-Ch FS USB UART Bridge, 64-LQFP | MaxLinear

The MaxLinear XR21B1424IV64-F is an enhanced 4-channel Full-Speed USB-to-UART bridge controller that integrates a USB 2.0 Full-Speed (12 Mbps) device interface with four independent enhanced UART channels, packaged in a 64-pin LQFP (10x10 mm). The part supports USB suspend, resume, and remote wakeup, and exposes programmable USB Vendor ID, Product ID, power mode, and remote wakeup behavior through internal EEPROM. A USB-to-UART bridge is a mixed-signal interface IC that converts USB packet traffic from a host controller into asynchronous serial (start/stop/data bit) streams that legacy MCUs and peripherals understand. Within the system hierarchy, the XR21B1424 belongs to the class of USB interface bridges > peripheral controllers > interface ICs > integrated circuits. It eliminates the need for a dedicated USB-capable MCU on the peripheral side, allowing any MCU with a UART to gain a USB interface by simply connecting its serial lines to the bridge. Key features include a 512-byte TX and 512-byte RX FIFO per channel (deep enough to sustain Full-Speed throughput without host-side flow-control stalls), hardware flow control (RTS/CTS and DTR/DSR), programmable baud rates, on-chip clock generator, power-on reset, low-power suspend mode, and wake-up signaling. Supply voltage is 3.0 V to 3.6 V or 4.4 V to 5.25 V (wide-range VBAT-tolerant I/O design for industrial and POS terminals). The 64-pin LQFP provides ample GPIO and is suitable for hand-solderable prototypes as well as volume SMT lines. The XR21B1424 architecture pairs a USB 2.0 Full-Speed PHY + SIE with four enhanced 16550-compatible UART cores. Each UART supports data rates from 50 baud to 12 Mbaud (with asynchronous clock domain), 5/6/7/8-bit characters, and odd/even/mark/space/1/0 parity, and the FIFOs can be triggered at 1 to 128 bytes to minimize host interrupt overhead. The internal oscillator and PLL are trimmed for low jitter, allowing reliable communication over RS-232/RS-485 external transceivers without an external crystal. Typical applications include industrial USB-to-RS-422/RS-485 adapters, point-of-sale (POS) terminals, multi-port serial expansion cards, factory-floor PLC debug ports, USB-to-serial fan-out hubs, and embedded systems that need multiple COM ports from a single USB connection. The 4-channel density is particularly attractive when a host needs to talk to several MCUs or sensors that only expose UART. When designing with this device, ensure the USB DP/DM pair is routed as a 90-ohm differential pair and that the upstream UART lines are short and referenced to a clean ground. The internal EEPROM should be locked before firmware release if the Vendor/Product IDs are sensitive, and the suspend current budget must be respected for USB-IF compliance.

XR3160EIU-F

XR3160EIU-F - RS-232/422/485 Multiprotocol Transceiver, 20-SSOP

The MaxLinear XR3160EIU-F is an advanced multiprotocol serial transceiver supporting RS-232, RS-485, and RS-422 standards from a single 3V to 5.5V supply, housed in a 20-pin SSOP package. It integrates 1/1 RS-232 driver/receiver channels plus 2/2 RS-422/RS-485 driver/receiver channels, with 15 kV ESD protection on the bus pins. The part supports RS-485/RS-422 data rates up to 20 Mbps and RS-232 data rates up to 1 Mbps. A multiprotocol transceiver is a single IC that bridges a UART or microcontroller to multiple physical-layer standards (RS-232, RS-485, RS-422), enabling one PCB design to serve point-to-point (RS-232), half-duplex multidrop (RS-485), or full-duplex differential (RS-422) links via software-mode selection. Within the broader hierarchy, the XR3160EIU-F belongs to the line transceiver / interface IC family, which itself sits under wired-connectivity semiconductors used in industrial automation, point-of-sale, and building-automation networks. The XR3160EIU-F's multiprotocol capability removes the need for two or three separate transceivers per port. Key features include an integrated charge pump that requires only four external 0.1 uF capacitors to generate RS-232 voltage levels from a single 3.3V or 5V rail, true fail-safe receivers for RS-485/RS-422 to guarantee a known output when the bus is idle or shorted, and a low-current shutdown mode (typical Icc < 10 uA) for battery-powered applications. The wide 3V to 5.5V supply range and TTL/CMOS-compatible logic inputs make it directly compatible with 3.3V MCUs and 5V legacy systems without level shifters. Architecturally, the XR3160EIU-F combines a charge-pump DC-DC converter with three driver channels and three receiver channels. Mode selection (RS-232 vs RS-485/RS-422, full- vs half-duplex) is performed via the logic inputs; the internal RS-485/RS-422 transmitters feature slew-rate-limited outputs and robust 15 kV HBM ESD protection on the bus pins, allowing the part to survive direct handling and harsh industrial transients. Typical applications include industrial PLC communication ports, multi-drop RS-485 sensor networks, point-of-sale (POS) terminals, building automation (BACnet / Modbus), and any embedded product that needs to support multiple serial protocols with one BOM line. Designers choose it when board space and component count are limited but protocol flexibility is required. When designing with the XR3160EIU-F, place the four charge-pump capacitors as close to the C1+ / C1- / C2+ / C2- pins as possible, use a solid ground plane, and observe RS-485 termination (120 ohm) only at the cable ends of long runs. The shutdown pin should be tied low through a 100 kohm pull-down if unused to prevent floating-mode glitches.

XR33180ESBTR - 52Mbps RS-485/422 Receiver | MaxLinear | 3-5.5V

The MaxLinear (formerly Exar) XR33180ESBTR is a high-performance 0/1 RS-485/RS-422 receiver housed in a 5-pin TSOT-23-5 (TSOT-5) surface-mount package, designed for serial communication applications up to 52Mbps. The device operates from a single 3.0V to 5.5V supply, supports 1/8 unit-load (up to 256 nodes on the bus), and provides ±15kV ESD protection on the bus pins per IEC 61000-4-2 air-gap discharge. A single-channel receiver-only topology simplifies point-to-point and multi-drop designs using an external transceiver such as the XR33183, or pairs directly with discrete driver ICs. A receiver is a serial-interface sub-block that converts a differential voltage on the RS-485/RS-422 bus into a single-ended logic-level signal for a UART, MCU, or ASIC. In the broader signal-composition hierarchy, an RS-485 receiver belongs to the line-driver/receiver family, which sits under the interface-IC category within power-management and connectivity ICs. Receiver-only parts like the XR33180 are used when system partitioning places the driver in another IC, when retrofitting an RS-485 receiver onto a board already containing a discrete or FPGA-based driver, or when a design needs bus-monitoring/diagnostics while the main driver is in high-impedance. Key specifications include a maximum data rate of 52Mbps, a wide 3.0V to 5.5V supply range, a 1/8 unit-load input impedance (allowing up to 256 nodes on a single bus), and an industrial operating temperature range of -40C to +85C. The receiver features a fail-safe open-circuit, short-circuit, and idle-bus design that guarantees a logic-high output when the bus is undriven, eliminating the need for external biasing resistors on many networks. The XR33180 uses a 5-pin TSOT-23 (Thin Small Outline Transistor) package with a 2.9mm x 1.6mm body, sharing the same land pattern as industry-standard TSOT-23-5 pinouts. This makes the part compatible with a range of pin-compatible RS-485 receiver drop-in alternatives from Maxim, TI, and Renesas. Logic outputs swing rail-to-rail and are TTL-compatible, supporting direct connection to 3.3V and 5V MCUs without level shifters. Typical applications include industrial field-bus networks (Modbus RTU, Profibus DP, BACnet), building automation (lighting, HVAC, security panels), motor-control and encoder feedback links, point-of-sale (POS) terminals, and any high-speed multi-drop RS-485 link where a small-footprint, robust-ESD receiver is required. The part is commonly paired with the XR33183 half-duplex transceiver or a discrete RS-485 driver in mixed designs. When designing with the XR33180, place a 100nF decoupling capacitor within 2 mm of the VCC pin and add a bulk 10uF capacitor near the supply rail. Keep the receiver differential inputs (A, B) impedance-controlled on the PCB; route them as a tightly-coupled 100-ohm differential pair to preserve signal integrity at maximum data rate. The fail-safe biasing is internal, so external fail-safe resistors are usually not required.

XR34350ILTR

XR34350ILTR - Multiprotocol RS-232/RS-485/RS-422 Transceiver | MaxLinear

The MaxLinear XR34350ILTR is an advanced multiprotocol serial transceiver supporting RS-232, RS-485, and RS-422 standards in a 40-pin QFN (6x6 mm) package. It delivers integrated cable termination, four configuration modes, and up to 20 Mbps RS-485/RS-422 throughput. According to the MaxLinear datasheet, the device operates from a single 3.3 V or 5.0 V supply (±5%) and requires only four external 0.1 µF charge pump capacitors for full operation. An RS-485/RS-422 multi-protocol transceiver is a single-chip interface IC that allows one physical port to communicate over multiple serial standards by reconfiguring its drivers and receivers. This category sits within the broader family of serial transceivers (also known as line transceivers or bus transceivers), which are essential building blocks inside the interface ICs tier of a system. By consolidating three standards into one IC, multiprotocol transceivers reduce BOM count, save PCB area, and let a single hardware design talk to legacy RS-232 equipment, RS-485 multidrop buses, and RS-422 point-to-point links on demand. Key features include 1 transmitter / 1 receiver (1Tx / 1Rx) in RS-485/RS-422 half or full duplex, full DB9-equivalent 3Tx / 5Rx support in RS-232 mode, a dedicated diagnostic loopback mode, integrated cable termination resistors, and wide output swing for robust signal margins. High-speed drivers reach 20 Mbps in RS-485/RS-422 and 1 Mbps in RS-232 mode. Four configuration pins select the active protocol at power-up with no external switching components required. The architecture combines a charge-pump DC-DC converter (the four external capacitors double and invert the supply to generate the RS-232 driver rails) with differential line drivers and receivers. Wide output swing ensures compliance with RS-232 ±15 V signaling even when powered from 3.3 V rails, while the integrated termination resistors eliminate external RS-485 120 Ω bias networks on the bus. Typical applications include multiprotocol industrial fieldbus gateways, point-of-sale (POS) terminals that must handshake with both legacy RS-232 peripherals and modern RS-485 instruments, telecom base station control ports, building automation controllers, and any embedded system that needs to bridge between RS-232, RS-422, and RS-422 segments on a single connector. When designing with this part, place the four charge-pump capacitors as close to the C1–C4 pins as possible with low-ESR ceramic types, and keep the MODE/SHDN pins either tied or driven by GPIOs. Note that activating the integrated termination draws additional supply current; disable it when not in use to save power.

XR4151CP-F

XR4151CP-F - V/F Converter, 8-22V, 100kHz | MaxLinear

The MaxLinear XR4151CP-F is a monolithic voltage-to-frequency (V/F) and frequency-to-voltage (F/V) converter IC supplied in an 8-pin PDIP through-hole package. It accepts a single-ended analog input voltage of 0 to 10 V (or -10 V to 0 V with appropriate biasing) and produces a proportional output pulse train whose frequency is linearly related to the input amplitude. The maximum full-scale frequency is 100 kHz with a usable range of 1 Hz to 100 kHz and a typical linearity error of +/-0.05%. A voltage-to-frequency converter (V/F or VFC) is a mixed-signal building block that translates a continuous analog voltage into a stream of digital pulses whose repetition rate is precisely proportional to the input magnitude. VFCs sit within the broader hierarchy of analog-to-digital conversion techniques alongside successive-approximation ADCs, dual-slope integrating ADCs, and sigma-delta modulators, and are valued for their inherent monotonicity, excellent noise rejection, and galvanic isolation-friendly pulse output that can be transmitted through optocouplers or long cables. Key features of the XR4151CP-F include a supply voltage range of 8 V to 22 V, very high noise rejection, inherent monotonicity over the full dynamic range, a single open-collector output stage that can interface with CMOS/TTL logic, and the ability to operate in reverse as a frequency-to-voltage converter with a small number of external components. The -F suffix denotes the lead-free, RoHS-compliant version of the original XR4151CP, while both share the same die and pinout. The internal architecture consists of a precision current source, a high-gain operational amplifier, a comparator, and a one-shot timing network. The op-amp drives a current into an external RC network whose charging time determines output pulse width; this architecture eliminates the missing-pulse and non-monotonic errors that plague simple charge-pump VFCs. The dedicated low-leakage input protection on pin 7 prevents the inverting input from being driven below ground, eliminating the need for an external clamp diode in most applications. Typical applications include precision analog-to-digital conversion where the output is fed to a counter or microcontroller capture input, isolated analog signal transmission across 4-20 mA replacement links, motor speed control via frequency-to-voltage conversion of tachometer pulses, and long-integral analog signal conditioning in industrial weighing, temperature, and pressure transmitters. When designing with the XR4151CP-F, choose the external timing resistor and capacitor first - the resistor sets the input current range and full-scale frequency, while the capacitor sets the one-shot pulse width. Add a 0.01 uF bypass capacitor close to the supply pin and use low-leakage timing components to maintain the 0.05% linearity specification. This page synthesizes distributor pricing, lead-time, pin-compatible alternatives, and practical design notes not found in the manufacturer datasheet, giving engineers a single-source decision framework for new designs and legacy XR4151CP replacement.

XRD8775AID-F - 8-Bit 20MSPS Flash ADC, 5V CMOS | MaxLinear

The MaxLinear (formerly Exar) XRD8775AID-F is an 8-bit, 20 MSPS analog-to-digital converter using a 2-step flash architecture in a 20-pin SOIC wide-body package. It operates from a single 5V supply, accepts analog inputs from 0V to VDD, supports a reference range of 1V to VDD, and integrates an internal sample-and-hold function that eliminates the need for an external track-and-hold amplifier. Typical power consumption is 75 mW (excluding reference current), enabling low-power system designs. An analog-to-digital converter (ADC) is a data converter that translates real-world continuous analog signals into discrete digital codes for processing by microcontrollers, FPGAs, or DSPs. Flash and 2-step flash ADCs achieve the highest sampling rates among all ADC architectures by using parallel comparator banks, making them well-suited for video, instrumentation, and high-speed control loops. The XRD8775AID-F belongs to the hierarchy: ADC -> data converter -> signal chain IC -> mixed-signal semiconductor. Key specifications include 8-bit resolution, 20 MSPS sampling rate, parallel digital interface, single 5V analog supply, internal S/H, 0V-to-VDD analog input range, and -40C to +85C operating temperature. The wide-body 20-SOIC package (0.295 inch / 7.50 mm width) provides robust thermal performance and ease of hand-soldering for prototyping. The part is offered in tube packaging for manufacturing. The 2-step flash architecture trades a small number of comparator channels for a substantial reduction in die area and power consumption versus a full flash design, while still maintaining video-grade 20 MSPS throughput. Internal S/H bandwidth supports IF undersampling and video bandwidth applications. The CMOS process ensures low power, latch-up free operation, and stable performance across the industrial temperature range. Typical applications include video digitisation, CCD camera front ends, digital oscilloscopes, ultrasound front-end preprocessing, IF sampling in communications receivers, and industrial process control loops. The combination of wide analog input range and integrated S/H simplifies board-level design for low-channel-count high-speed data acquisition. When designing with this part, place a 0.1 uF ceramic decoupling capacitor as close as possible to the VDD pin and a bulk tantalum or electrolytic capacitor on the analog supply rail. The reference pin requires a low-impedance source; use an op-amp buffer or a dedicated reference IC if the application demands better than 8-bit absolute accuracy.

XRD8775AIU

XRD8775AIU - 8-Bit 20MSPS Flash ADC, 20-SSOP | MaxLinear

The MaxLinear (formerly Exar) XRD8775AIU is a monolithic CMOS 8-bit flash analog-to-digital converter delivering up to 20 MHz sampling rate in a 20-pin SSOP package. It integrates an internal sample-and-hold amplifier, operates from a single +5 V supply, and consumes only 75 mW typical (excluding external reference current). The input voltage range spans 0 V to VDD with a flexible reference voltage range of 1 V to VDD, allowing direct interface with single-supply analog signal chains. An 8-bit flash ADC is a parallel-architecture converter that uses 2^N-1 comparators to digitize an analog input in a single clock cycle, delivering the fastest conversion latency of any ADC topology at the cost of exponential die-area growth with resolution. Flash converters therefore dominate sub-10-bit, multi-MHz applications such as video digitizers, digital oscilloscope front ends, and radar IF samplers where latency and sampling rate, not resolution, are the primary constraints. Key specifications of the XRD8775AIU include 8-bit resolution, 20 MSPS maximum sampling rate, internal S/H, single +5 V supply operation, 75 mW typical power dissipation, latch-up-free CMOS construction, and 2000 V minimum ESD protection. The parallel data interface simplifies connection to FPGAs, ASICs, or microcontrollers without requiring a serial programming sequence. The 20-SSOP package suits space-constrained boards where analog and digital grounds can be partitioned for noise immunity. Architecturally, the device uses 255 parallel latched comparators feeding a priority encoder that generates an 8-bit thermometric code, then a binary encoder delivers the output word in a single clock edge. The internal sample-and-hold amplifier stabilizes the input within the aperture window, which is critical for full-scale inputs above 10 MHz to avoid code-edge distortion. The reference ladder is externally driven, giving the designer freedom to set the LSB size by scaling VREF between 1 V and VDD. Typical applications include digital oscilloscope input channels, video digitizers, CCD imaging front ends, radar IF sampling, ultrasound beamforming pre-processors, and industrial data-acquisition front ends. The 75 mW dissipation also suits portable test gear and battery-powered instrumentation where the internal S/H eliminates an external track-and-hold IC. Design tip: Place a 0.1 uF ceramic decoupling capacitor within 5 mm of the VDD pin and a bulk 10 uF tantalum capacitor near the analog ground island; route the 8-bit parallel bus with matched trace lengths to prevent sub-LSB timing skew at the full 20 MSPS rate. Also bypass the external VREF pin with 10 uF to keep the internal resistor ladder stable and reduce sparkle-code errors.

XRD8775AIU-F - 8-Bit 20MSPS Parallel ADC | MaxLinear | Exar

The MaxLinear XRD8775AIU-F is an 8-bit resolution, 20MSPS sampling rate analog-to-digital converter (ADC) with a single-ended input and parallel digital data interface, housed in a 20-pin SSOP package. Originally introduced by Exar Corporation and now sold under MaxLinear, the part is specified as IC ADC 8BIT PAR 20MSPS 20SSOP and operates from a single 5V analog supply. An analog-to-digital converter (ADC) is a data-acquisition integrated circuit that samples continuous analog signals and converts them into discrete digital codes. Flash ADCs like the XRD8775AIU-F use an array of comparators to deliver the fastest conversion times, typically reserved for video, instrumentation, and high-speed control loops where sub-microsecond conversion latency is mandatory. The 8-bit, 20MSPS segment sits at the entry level of high-speed conversion and is well suited for digitizing video bandwidths, IF signals, and oversampled measurement channels. Key features per the manufacturer datasheet include 8-bit resolution, 20 MHz maximum sampling rate, an internal sample-and-hold (S/H) function, a single-ended analog input range of 0V to VDD, a reference input range of 1V to VDD, and typical power consumption of 75 mW (excluding reference current). The device provides latch-up free operation and ESD protection rated at 2000V minimum, simplifying board-level robustness. The XRD8775AIU-F uses a flash converter architecture with a 1:1 S/H-to-ADC ratio, providing a single simultaneous sampling channel with a parallel 8-bit output bus. This architecture removes the need for an external track-and-hold amplifier in most digitizer front ends and simplifies downstream FPGA or ASIC capture logic. Typical applications include standard-definition video digitizers, CCD/camera signal chains, ultrasound front-end signal conditioning, IF sampling for communications receivers, and high-speed industrial inspection systems. The 20MSPS capability comfortably handles component video and baseband IF signals up to about 7 MHz of input bandwidth. When designing with this part, ensure the analog input drive network presents low source impedance at the Nyquist frequency and that the reference pin is decoupled with a low-ESR capacitor placed within 5 mm of the package pin. Because the part is sourced via MaxLinear (after the Exar acquisition) and is listed as obsolete in some distributor databases, confirm long-term supply before committing to high-volume production.

XRD8785AID-F

XRD8785AID-F - 8-Bit 20MHz Flash ADC, 24-SOIC | MaxLinear

The MaxLinear (formerly Exar) XRD8785AID-F is an 8-bit, 20 MSPS flash analog-to-digital converter (ADC) with one input channel, housed in a 24-pin SOIC wide-body package. It uses an advanced 5V CMOS process and provides 8-bit resolution, up to 20 MHz sampling rate, an internal sample-and-hold function, and a single 5V analog supply. The device accepts an input range of 0V to VDD and a reference range of 1V to VDD, making it suitable for general-purpose digitizing of unipolar signals. Latch-up free operation and a minimum 2 kV ESD protection rating ensure robust real-world handling during board assembly and field use. An 8-bit flash ADC is the fastest ADC architecture, using 2^8 (256) parallel comparator-latch cells and a resistor reference ladder to convert an input voltage to a digital code in a single clock cycle. Flash ADCs occupy the low-resolution, very-high-speed corner of the converter family tree: SAR ADCs (successive approximation) offer higher resolution at lower speed, while pipelined ADCs sit between them. Flash ADCs therefore dominate in digital oscilloscopes, video digitizers, CCD imaging front-ends, radar IF sampling, and digital receiver IF strips where sub-100 ns latency matters more than 12-16 bit precision. Key features of the XRD8785AID-F include 5V single-supply operation, a typical power dissipation of 75 mW excluding the reference current, an internal S/H that removes the need for an external track-and-hold amplifier, and three-state CMOS-compatible digital outputs. Its flash topology delivers full-code conversion in a single clock, and the 24-SOIC package exposes all digital outputs and the S/H control pins for easy parallel interfacing to FPGAs, microcontrollers, or display controllers. Typical applications for the XRD8785AID-F include digital oscilloscope front-ends, video digitizers, CCD imaging signal chains, instrumentation digitizers, and communication IF sampling. The simple 5V/CMOS interface, parallel output bus, and low 75 mW dissipation also suit it for board-level prototyping where a fast acquisition path is needed without the cost of a precision ADC. When designing with this device, follow the datasheet's recommended decoupling and reference bypassing carefully. Place a 0.1 uF ceramic bypass close to the analog supply pin and a 10 uF bulk tantalum or ceramic capacitor nearby; bypass the reference pin with a low-impedance capacitor so the high-speed comparator ladder does not see reference bounce. For engineers evaluating the XRD8785AID-F, DigiKey, Mouser, and Octopart list it as an active MaxLinear SKU with multiple distributor stocks, while legacy Exar datasheet PDFs remain valid references.

The MaxLinear XRD8785AIDTR-F is an 8-bit flash analog-to-digital converter (ADC) sampling at up to 20 MSPS with a single 5V supply, housed in a 24-pin wide-body SOIC package (0.295 inch / 7.50 mm body width) shipped on tape and reel. Key electrical parameters include 8-bit resolution, 20 MHz maximum sampling rate, one single-ended analog input, internal sample-and-hold (S/H), external or internal reference option, 0V-to-VDD analog input range, 1V-to-VDD reference range, 75 mW typical power consumption (excluding reference), and an operating temperature range of -40C to +85C. The suffix "D" indicates the 24-SOIC package, "T" indicates tape-and-reel packaging, and "R-F" denotes the MaxLinear / Exar part-numbering convention. A flash ADC is a type of analog-to-digital converter that uses a parallel bank of 2^n comparators to convert an analog signal to an n-bit digital code in a single clock cycle, achieving the highest sampling speed of any ADC architecture. The hierarchy is: ADC -> data converter -> data acquisition IC -> mixed-signal IC -> semiconductor. Flash converters excel in applications demanding low latency and wide input bandwidth, but they trade resolution and power efficiency against sampling speed. The XRD8785AIDTR-F occupies the entry-level 8-bit, 20 MSPS tier, which is the typical sweet spot for video digitisation, ultrasound receive beams, and intermediate-frequency (IF) sampling in low-cost communications receivers. Key features of this device include a parallel (TTL-compatible) digital output bus, internal S/H front-end, latch-up free CMOS construction, ESD protection on analog and digital pins, single 5V supply operation, and low power consumption at 75 mW typical. The 24-SOIC wide-body package measures approximately 15.4 mm x 7.5 mm x 2.35 mm, providing generous die-to-board clearance for through-hole or socketed prototypes. The device is built on a 5V CMOS process, providing low power consumption, latch-up immunity, and ESD protection. Internal reference mode simplifies bill-of-materials, while external reference mode lets designers optimise linearity or temperature drift for instrumentation-grade designs. Typical applications include video digitisation, digital oscilloscope front-ends, IF sampling in communications receivers, CCD/CMOS image sensor digitisation, and industrial control loop sampling. When designing with this device, ensure the analog input signal is bandwidth-limited to less than the Nyquist frequency (10 MHz for 20 MSPS) and that the external reference decoupling capacitor is placed within 5 mm of the REF pin to prevent kickback noise from corrupting the conversion.

XRD8799AIQ - 10-Bit 2MSPS 8-Ch ADC | MaxLinear/Exar | 44-PQFP

The MaxLinear XRD8799AIQ (originally Exar) is a 10-bit resolution, 2 MSPS pipelined analog-to-digital converter with an integrated 8-channel analog input multiplexer, housed in a 44-pin PQFP (10x10 mm) package. It combines low-power CMOS operation (35 mW typical active, 0.8 mW in power-down) with a wide input range spanning GND to VDD, eliminating the need for external signal-conditioning scaling on most signals. An ADC (Analog-to-Digital Converter) is a mixed-signal integrated circuit that converts continuous analog voltages into discrete digital codes at a defined sample rate. The XRD8799AIQ belongs to the multi-channel, low-power successive-approximation/pipelined ADC family - a category that sits inside the broader hierarchy of data converter -> data acquisition IC -> mixed-signal semiconductor. It is purpose-built for systems that must digitize multiple analog sources while staying within strict power and board-area budgets. Key differentiating specifications include 10-bit resolution, a 2 MHz maximum sampling rate, eight single-ended input channels routed through an on-chip mux, parallel digital output, and an input range that accepts rail-to-rail signals without external scaling. A built-in power-down mode drops consumption to 0.8 mW typical, and the device does not require an external sample-and-hold for analog signals below 100 kHz or for CCD-type signals, simplifying the analog front end and BOM cost. Architecturally, the converter uses a pipelined topology that distributes conversion work across multiple low-resolution stages, achieving higher throughput than pure SAR architectures at comparable power. The integrated 8-channel mux eliminates an external analog switch tree, reducing board space, leakage paths, and channel-to-channel crosstalk sources. The PQFP-44 package gives a generous thermal pad and 10 mm x 10 mm footprint suitable for both hand-solderable prototyping and SMT production. Typical applications include CCD signal acquisition in industrial imaging, multi-sensor data logging in process control, portable instrumentation with battery operation, and mixed-signal front ends for embedded controllers. Industrial multi-channel data-acquisition boards and portable medical monitoring devices frequently select this part for its combination of throughput and low quiescent draw. When designing with the XRD8799AIQ, note that input signals below 100 kHz do not need an external track-and-hold, but faster signals should be buffered to maintain dynamic performance. Place a 0.1 uF decoupling capacitor close to each supply pin and follow the manufacturer's reference ground layout to keep digital switching noise out of the analog path.

The MaxLinear (formerly Exar) XRD87L75AID-F is a low-voltage CMOS 8-bit analog-to-digital converter with a maximum sampling rate of 10 MSPS, an internal sample-and-hold, and a single 3.3V supply rail. It is housed in a 20-pin SOIC (0.295 inch / 7.50 mm body width, D-suffix package) and is provided in tube packaging per the -F factory suffix. An 8-bit flash ADC is a type of analog-to-digital converter that uses a parallel bank of 2^n comparators to convert an input voltage into a digital code in a single clock cycle, achieving the fastest possible conversion latency at moderate resolution. Within the broader signal-chain taxonomy, the XRD87L75AID-F sits between a traditional sample-and-hold stage and a digital host (FPGA, ASIC, or microcontroller), and is a member of the speed-optimized, low-resolution ADC family used for video, instrumentation, and IF digitisation. Key features include 8-bit resolution, a 10 MHz typical sampling rate, an internal track-and-hold, an analog input range of 0V to VDD, a reference input range of 1V to VDD, and typical power dissipation of 25 mW (excluding reference current). The device is latch-up free, operates from a single 3.3V supply, and uses a parallel CMOS-compatible digital interface, which simplifies connection to modern MCUs and FPGAs without external level shifters. The device is built on an advanced 3.3V CMOS process and uses a flash architecture to deliver 10 MSPS conversion speeds. Its internal S/H function guarantees a stable sample window across rapidly-changing inputs and avoids the need for external S/H circuitry, simplifying the analog front-end. Typical applications include video digitisation, CCD imaging front-ends, digital oscilloscope front-ends, IF sampling in communications, portable instrumentation, and general-purpose high-speed data acquisition. The wide analog input range (0V to VDD) lets designers digitise single-ended signals without external attenuators. When designing with this device, ensure the analog input is properly driven (low-impedance buffer recommended) and that the reference decoupling is solid. The single 3.3V supply simplifies the power tree but requires that downstream digital logic be 3.3V tolerant.

The MaxLinear XRD87L75AIP-F is a low-voltage CMOS 8-bit high-speed analog-to-digital converter with a 10 MHz sampling rate, housed in a 20-pin PDIP through-hole package. It features a single 3.3 V supply rail, an internal sample-and-hold function, an analog input range of 0 V to VDD, and a reference input range of 1 V to VDD, achieving typical power dissipation of 25 mW excluding the external reference. What is an 8-bit ADC? An analog-to-digital converter (ADC) is a data converter that samples a continuous analog waveform and produces a discrete digital code proportional to the input voltage at each clock edge. 8-bit ADCs deliver 256 discrete codes (1 LSB = full-scale / 256), which suits digital instrumentation, video digitizing, and digital oscilloscope front ends where 8-bit dynamic range is sufficient. Within the data-converter hierarchy, an 8-bit ADC sits below SAR and pipelined converters in resolution but above flash converters in speed and below the latest 12-/14-/16-bit parts in accuracy. The 10 MSPS sampling rate places this part in the legacy high-speed, low-resolution tier used in CRT digitizers, image scanners, ultrasound receive channels, and digital IF processing. Key features include latch-up free CMOS construction, parallel digital output, single 3.3 V supply operation, internal S/H function, and a wide reference input voltage range from 1 V to VDD for design flexibility. The 2-step flash architecture minimizes comparator count while delivering 10 MSPS throughput, and the part is offered as a Pb-free (RoHS-compliant) 20-pin PDIP variant suitable for industrial, instrumentation, and test-equipment applications. The XRD87L75AIP-F integrates the input track-and-hold, reference buffer, and decoding logic on a single CMOS die, allowing direct connection to a microcontroller or DSP data bus. The 25 mW typical power consumption (excluding reference) supports portable and battery-powered instruments. The 3.3 V single supply also matches CMOS logic families, simplifying interface to FPGAs and microcontrollers without level translation. Typical applications include digital oscilloscope front ends, video digitizers, ultrasound imaging receive channels, point-of-sale barcode scanners, and industrial process control data acquisition. The wide 0 V to VDD input range allows direct sampling of single-ended signals without external signal conditioning. When designing with this part, place a 0.1 uF bypass capacitor close to the VDD pin and ensure the reference input is driven by a low-impedance source. For best linearity, route CLK and digital outputs away from the analog inputs to minimize crosstalk.

XRD87L75AIU - 8-Bit 10MSPS ADC, 3.3V, SSOP-20 | MaxLinear

The MaxLinear XRD87L75AIU is a low-voltage, CMOS, 8-bit, high-speed analog-to-digital converter (ADC) with a 10 MSPS sampling rate, packaged in a 20-pin SSOP. Operating from a single 3.3 V supply, it features an internal sample-and-hold function, an analog input range of 0 V to VDD, and a reference input range of 1 V to VDD, dissipating a typical 25 mW (excluding reference current). What is an 8-bit ADC? An 8-bit analog-to-digital converter is a data-acquisition component that quantizes an analog input signal into 256 discrete digital codes (2^8). ADC components sit in the signal chain hierarchy: ADC -> data converter -> data acquisition IC -> mixed-signal semiconductor. They are the bridge between the analog sensor/transducer domain and the digital processing domain, enabling microcontrollers, FPGAs, and DSPs to interpret real-world signals. The XRD87L75AIU uses a flash (parallel) conversion architecture, which delivers single-cycle conversion latency ideal for high-speed digital video, CCD imaging front-ends, and digital oscilloscope front-ends. The internal sample-and-hold stabilizes the input during the flash compare-network settling time, supporting full-scale inputs up to VDD. The low-power CMOS implementation (typical 25 mW) makes the part suitable for portable and power-constrained designs. The 3.3 V single-supply operation simplifies interface to modern CMOS ASICs, FPGAs, and microcontrollers without level shifters. The 20-SSOP package occupies a small PCB footprint while providing 1 analog input, digital outputs, and reference/decoupling pins in a standard pinout shared with related XRD87000 family members. Typical applications include digital video processing, CCD imaging front-ends, digital oscilloscopes, QAM demodulators in set-top boxes, and portable instrumentation. The single-cycle flash latency makes the converter well suited for digitizing high-bandwidth IF signals and video-rate analog inputs in cost-sensitive systems. When designing with this part, place a 0.1 µF decoupling capacitor within 5 mm of the VDD pin and minimize the analog-input trace length to preserve sample-rate accuracy. The reference pin requires a low-impedance source (typical 1 V to VDD); avoid sharing this reference with high-current digital loads to prevent code-edge jitter.

XRD87L75AIUTR-F

XRD87L75AIUTR-F - 8-Bit 10MSPS Flash ADC, 20-SSOP | MaxLinear

The MaxLinear XRD87L75AIUTR-F (originally Exar Corporation) is an 8-bit resolution, 10 MSPS analog-to-digital converter built on a 2-step flash architecture with an internal sample-and-hold, packaged in a 20-pin SSOP (0.209 inch / 5.30 mm width) with tape-and-reel packaging. It operates from a single 3.3 V supply, accepts a single-ended analog input from 0 V to VDD, and provides an external reference input range of 1 V to VDD for flexible full-scale setting. An ADC (Analog-to-Digital Converter) is a data acquisition integrated circuit that converts continuous analog signals into discrete binary codes at a defined sampling rate. Within the broader hierarchy, this device sits as: ADC -> data converter -> data acquisition IC -> mixed-signal semiconductor. The 2-step flash architecture is a variant of the flash ADC that halves the comparator count versus a full flash, reducing both die cost and input capacitance, while the integrated S/H eliminates the need for an external track-and-hold amplifier in most applications. Key features include 8-bit resolution at 10 MHz sampling rate, single 3.3 V supply operation with 25 mW typical power dissipation (excluding external reference current), parallel digital output interface for direct connection to microcontrollers, DSPs, or FPGAs, and latch-up free CMOS construction for robust ESD/handling performance. The internal sample-and-hold eliminates external S/H requirements and supports full Nyquist bandwidth input frequencies, making the device suitable for general-purpose digitizing tasks where cost-per-channel matters. The XRD87L75AIUTR-F architecture uses a 2-step flash topology with on-chip S/H, error correction, and a parallel CMOS-compatible output bus. Its low input capacitance and high input bandwidth reduce drive-amplifier loading, and the part is specified to operate from a single 3.3 V rail, simplifying power tree design in 3.3 V logic systems. The internal reference buffer accepts a user-supplied reference from 1 V to VDD for system-level gain calibration. The -F suffix denotes the lead-free, RoHS-compliant tape-and-reel packaging option. Typical applications include video digitizing and graphics capture, CCD/CIS sensor front-ends, digital oscilloscope front-ends, baseband IF sampling, low-cost digital imaging, and portable instrumentation. The 8-bit/10 MSPS combination aligns well with standard-definition video bandwidths (~5 MHz) and consumer imaging throughput requirements. When designing with this part, place the input RC anti-alias filter directly at the analog input pin and provide a low-impedance reference buffer because the reference pin input current scales with sampling rate. Parallel output bus traces should be length-matched and series-terminated near the ADC to limit digital switching noise coupling back into the analog input. Decouple VDD with both a 0.1 uF ceramic and a 10 uF bulk capacitor placed within 5 mm of the supply pin.

XRD87L99AIQ-F

XRD87L99AIQ-F - 10-Bit 2 MSPS 8-Ch MUX ADC | MaxLinear

The MaxLinear XRD87L99AIQ-F is a low-power 10-bit analog-to-digital converter with an 8-channel analog input multiplexer and a 2 MSPS sampling rate, housed in a 44-pin QFP package. It operates from a single 2.7V to 5.5V supply, draws only 24 mW typical at full speed, and falls to 0.1 mW in its hardware power-down mode. The device requires no external sample-and-hold for input signals below 100 kHz or for CCD-style signals, simplifying analog front-end design. An ADC (analog-to-digital converter) is a mixed-signal integrated circuit that samples continuous analog voltages into a parallel digital word at a defined clock rate. ADCs sit within the broader hierarchy of data acquisition ICs -> data converters -> mixed-signal ICs -> integrated circuits, and they are the critical bridge between analog sensors and digital processors. Multi-channel, low-power ADCs like the XRD87L99AIQ-F are typically used to digitize several sensors with one converter, reducing board area, BOM cost, and software overhead in embedded designs. Key features of the XRD87L99AIQ-F include 10-bit resolution, an integrated 8-to-1 analog multiplexer with channel-address latches, a parallel microprocessor-compatible digital interface, an external reference input, and a hardware power-down pin. Its wide input range covers GND to VDD, which lets the device directly digitize rail-to-rail sensor outputs. The 44-QFP package is industry-standard and supports conventional surface-mount assembly. Typical applications for the XRD87L99AIQ-F include multi-channel data acquisition systems, CCD signal processing chains in scanner and copier subsystems, portable and battery-powered instrumentation, industrial process monitoring, and embedded control boards that need to read several analog sensors at moderate speeds. In each case the device's low power dissipation, integrated mux, and parallel interface reduce both component count and software complexity. Designers should remember that the XRD87L99AIQ-F is in EOL/last-time-buy status according to distributor lifecycle fields, so long-life designs should plan for a qualified replacement or place a last-time-buy order. Drive the analog inputs with low-impedance sources to keep the input settling error inside the 10-bit budget, and place the 0.1uF VDD decoupling capacitor within a few millimeters of the supply pin.
