USB2514I-HZH - USB 2.0 HS 4-Port Hub Controller | Microchip
USB2514I-HZH

USB2514I-HZH - USB 2.0 HS 4-Port Hub Controller | Microchip

Microchip Technology USB2514I-HZH is a USB 2.0 high-speed four-port hub controller packaged in a 48-pin VQFN with an exposed pad and supplied in a tray. The verified product information identifies it as a low-speed, full-speed, and high-speed hub controller operating from a 3.3 V supply. Its four-port USB interface architecture makes it relevant to systems that need to expand a single host USB connection across several peripherals while retaining USB 2.0 high-speed support. A USB hub controller is an interface integrated circuit within the broader USB interface-controller hierarchy. It manages traffic between an upstream USB host and multiple downstream USB ports, allowing peripheral devices such as keyboards, storage adapters, communications equipment, and human-interface devices to share one host port. A four-port USB 2.0 implementation is especially relevant to embedded systems, industrial control panels, test benches, and compact peripheral systems that require more attachment points than a host controller exposes directly. The verified product data highlights three defining characteristics: USB 2.0 high-speed operation, four downstream hub ports, and a 48-pin VQFN exposed-pad package. The USB2514I-HZH is also identified as an industrial-temperature-rated part. Microchip describes the related USB251xB family as cost-effective and power-efficient while using MultiTRAK technology to support mixed-speed USB data throughput. These features distinguish it from basic four-port repeater devices by placing port management, signaling, and USB connectivity in one dedicated controller. The part operates from 3.3 V and supports low-speed, full-speed, and high-speed USB devices, allowing a mixed-speed peripheral set to share the same hub. That mixed-speed capability is useful when a design includes legacy USB devices alongside high-speed peripherals. The exposed-pad package also provides a defined thermal and electrical land pattern that must be connected according to the manufacturer layout guidance rather than treated as an unused pin. Typical applications include industrial USB expansion, embedded instrumentation, laboratory data-acquisition systems, USB-to-serial equipment, and peripheral hubs for host computers or embedded controllers. In these systems, the hub can consolidate several external functions behind one upstream USB connection while the controller manages enumeration, downstream port behavior, and data traffic. The USB2422-CP-TR and USB2517I-JZX are related USB interface components available through XAIPART for broader design evaluation. Designers should verify the complete pin assignment, electrical limits, crystal or clock requirements, port-current budget, and exposed-pad connection against the manufacturer datasheet before layout release. The verified distributor information confirms a 48-pin VQFN exposed-pad package and tray packaging, but it does not provide the complete pinout, operating-temperature interval, power dissipation, or recommended external-component values. This product record combines verified manufacturer and distributor information with an explicit comparison of available same-package alternatives, commercial pricing, and application guidance. Missing technical values are marked rather than guessed, allowing engineers to distinguish confirmed USB2514I-HZH characteristics from details that still require direct datasheet verification.

USB2517-JZX - 7-Port USB 2.0 Hi-Speed Hub Controller | Microchip
USB2517-JZX

USB2517-JZX - 7-Port USB 2.0 Hi-Speed Hub Controller | Microchip

The Microchip USB2517-JZX is a versatile, cost-effective, and power-efficient 7-port USB 2.0 Hi-Speed hub controller IC in a 64-pin QFN (9x9 mm) package with exposed thermal pad, designed for low-power, small-footprint embedded USB applications. It provides seven downstream USB ports, supports Low-Speed (1.5 Mbps), Full-Speed (12 Mbps), and Hi-Speed (480 Mbps) downstream devices, and operates from a 1.8V/3.3V supply rail. A MultiTRAK™ multi-transaction translator enables concurrent Full-/Low-Speed traffic on multiple downstream ports without bandwidth starvation, and the upstream port supports Hi-Speed operation in accordance with the USB 2.0 specification (April 27, 2000, with 12/7/2000 and 5/28/2002 errata). A USB hub controller is an Interface IC that aggregates multiple USB peripherals behind a single upstream port, presenting each downstream port to the host as an independent device while managing enumeration, power, and transaction translation. Within the broader system hierarchy, the USB2517-JZX sits at Interface IC → USB Controller → USB Hub Controller → USB 2.0 Hi-Speed Hub. Hub controllers are essential building blocks of docking stations, monitors, embedded industrial PCs, and consumer electronics that need to expand a single host USB root port into several usable downstream ports. Key features include per-port or ganged power switching, individual port over-current sensing, integrated 1.5 kΩ upstream pull-up resistor, OTP/serial EEPROM configuration, and support for both bus-powered and self-powered hub topologies. The 64-QFN package with EP provides low thermal resistance and a small 9x9 mm PCB footprint. The device supports SMBus or I²C configuration, complies with USB Battery Charging Specification 1.1 pre-configurations, and integrates an internal 3.3V regulator requiring only a single 3.3V supply or a 5V VBUS-derived rail. The architecture combines a USB 2.0 physical layer (PHY) and a serial interface engine (SIE) per port with a hub repeater and a MultiTRAK transaction translator. This allows multiple Full-/Low-Speed devices to communicate simultaneously with the host at full USB 2.0 bandwidth, eliminating the bandwidth bottleneck found in single-TT hub designs. The hub repeater handles connect/disconnect, suspend/resume, and reset signaling, while per-port PHYs provide signal integrity at 480 Mbps across PCB traces of typical lengths. Typical applications include USB port expansion in monitors, docking stations, industrial PCs, embedded computing, and consumer hubs. It is also used in test equipment, automotive infotainment head units, and any product that must turn one host port into seven USB 2.0 ports. The 1.8V/3.3V flexible supply and small 9x9 mm QFN make it ideal for space-constrained embedded designs. When designing with this part, ensure that the upstream port's 90 Ω differential pair is routed as a length-matched, impedance-controlled USB 2.0 microstrip with a continuous reference ground plane. Place the 480 MHz crystal or oscillator reference as close as possible to the XI pin, and decouple each VDD pin with a 0.1 µF X7R ceramic cap tied to a solid ground pour. A common pitfall is forgetting to populate the upstream series choke or ESD protection array; the hub will enumerate but fail USB-IF compliance without these. This page synthesizes current distributor pricing, same-brand drop-in alternatives from the USB251x family, and practical design notes that go beyond the manufacturer datasheet to help engineers shorten time-to-prototype.

The controller supports Low-Speed, Full-Speed, and Hi-Speed downstream devices when operating as a Hi-Speed hub, while its upstream attachment can operate as a Full-Speed or Full-/Hi-Speed hub. A USB hub controller is an interface semiconductor that manages traffic between one upstream USB host and multiple downstream devices. It belongs to the USB interface controller, interface IC, and connectivity semiconductor hierarchy. The USB2517 family uses MultiTRAK technology to support mixed-speed USB environments while helping embedded designs consolidate multiple peripheral connections behind one upstream host interface. The USB2517I is identified in the verified data as the industrial-temperature-rated member of the USB2517 family. Its 64-QFN 9 x 9 mm package supports compact embedded implementations, while the integrated hub function reduces the need for discrete USB routing and control components. The device is described by Microchip as low power and OEM configurable, making it suitable for system-level USB port expansion where firmware, hub configuration, and downstream-port requirements are controlled by the OEM. Typical embedded uses include industrial equipment, test systems, printers, storage appliances, communications equipment, and other products that need more USB connections than a host controller provides directly.

USB2524-ABZJ - USB 2.0 4-Port Switching Hub | Microchip
USB2524-ABZJ

USB2524-ABZJ - USB 2.0 4-Port Switching Hub | Microchip

The Microchip Technology USB2524-ABZJ is a USB 2.0 multi-switch hub controller with two upstream host connections, four downstream ports, and a 56-QFN-EP surface-mount package measuring 8 mm by 8 mm. Its stated operating supply range is 3.0 V to 3.6 V, while USB 2.0 Hi-Speed operation supports 480 Mbps signaling. The controller provides electronic reconfiguration and reassignment of any downstream port to either upstream host on the fly. A USB hub controller is an interface integrated circuit that coordinates communication between one or more USB hosts and attached peripherals. In the broader hierarchy, USB2524-ABZJ belongs to the USB interface controller family, which sits within interface ICs and broader semiconductor devices. Unlike a conventional four-port hub with only one upstream connection, this device combines a Hi-Speed hub with switching logic so two hosts can share the same downstream device set. The USB2524 is identified by Microchip as the industry's first USB switching hub combining USB Hi-Speed hub and switching functions in one device. Its two upstream ports and four downstream ports enable USB device sharing, dynamic host ownership, and reassignment without physically moving equipment. All required resistors on the USB ports are integrated according to the manufacturer data sheet, reducing discrete termination content on the PCB. Operationally, the controller is intended to work with an external USB power-distribution switch device. That external device controls VBUS switching to downstream ports, limits current, and senses over-current conditions. The separation between data-port switching and power-distribution control allows a board designer to use a suitably rated power switch instead of integrating high-current switching entirely inside the 56-QFN controller. Typical uses include shared test benches, industrial peripheral-sharing systems, embedded equipment with multiple USB hosts, kiosk configurations, and automatic test equipment that needs a peripheral to move between hosts. The 3.0 V to 3.6 V supply range suits conventional 3.3 V digital systems, although the complete board must also meet USB signal-integrity, impedance, VBUS, and current-protection requirements. Layout is the principal implementation constraint for this 56-QFN-EP device. Differential USB data pairs require controlled impedance and minimized mismatch, while the exposed pad needs a deliberate thermal and ground strategy. Designers should also follow the manufacturer's USB layout guidance and confirm external power-switch selection, port-current budgets, EEPROM requirements, and all pin functions against the current USB2524 data sheet. This page consolidates the verified manufacturer and distributor information, distinguishes confirmed electrical facts from unspecified parameters, and provides application, sourcing, and design guidance. It also records the absence of a verified pin-to-pin substitute rather than presenting functionally similar or differently packaged USB controllers as drop-in replacements.

USB2602-NU-02

USB2602-NU-02 - USB 2.0 4-Port Hub Controller | Microchip

The Microchip Technology USB2602-NU-02 is a USB 2.0 compound-device controller that combines a three-port downstream USB hub and a Flash Card Media Controller in a 128-lead TQFP package. Its operating supply range is 3 V to 3.6 V, and the listed -NU-02 ordering code identifies the USB 2.0 interface, Flash Media, four-port hub configuration supplied in a 14 mm by 14 mm TQFP package. The controller is intended to sit between one upstream USB host and downstream USB devices while also supporting Flash media connectivity. A USB hub controller is an interface IC within the broader USB interface-controller and semiconductor hierarchy. It manages port connectivity, power distribution, and data transfer between an upstream host and downstream peripherals. A compound device combines multiple USB functions within one controller, allowing the USB2602 to provide hub and Flash media functionality without requiring a separate hub controller for each function. This integration can reduce board-level component count and simplify enclosure and product design. The USB2602 family supports xD Picture Card format for licensees, as stated by the manufacturer product page. Its USB 2.0 architecture targets host-side accessories, card readers, multifunction peripherals, and embedded USB products requiring a compact hub-and-media-controller solution. The supplied distributor records identify the component as a four-port hub controller and list DigiKey and Mouser as sources for technical data, pricing, and availability. The device operates from a 3 V to 3.6 V supply, allowing use with 3.3 V system rails. Because USB devices impose strict signal-integrity, enumeration, and current-management requirements, board implementation should follow the manufacturer reference design and recommended external-component layouts rather than treating the controller as a generic USB switch. Input and output impedance-controlled traces, short differential connections, solid ground planes, and careful separation between high-current and low-level data paths are particularly important in compact four-port implementations. Typical installations include USB 2.0 card readers, multifunction docking products, removable-media appliances, and compact embedded USB hubs. The integrated hub and Flash media functions are useful where one upstream connection must serve multiple USB peripherals while also reading Flash-based storage. Engineers should confirm host compatibility, supported media formats, electrical characteristics, and enclosure requirements against the current manufacturer documentation before production release. The principal design consideration is validating the complete USB power, firmware, and signal path rather than selecting the IC from headline hub features alone. The 3.3 V supply requirement, upstream and downstream routing, downstream-port current budget, Flash interface implementation, and mechanical package all affect whether the controller is suitable for a given product. This page combines manufacturer function data, distributor availability references, package information, sourcing links, and application-focused engineering guidance. It also distinguishes verified USB2602-NU-02 data from suffix variants whose detailed electrical and pin-level differences are not supplied in the source material, helping engineers make a safer procurement or replacement decision.

Its 48-QFN package supports compact surface-mount designs, while the exposed-pad package construction provides a defined thermal and electrical land pattern. The device is intended for systems that need local USB port expansion together with removable flash-media connectivity. Typical uses include USB docking stations, compact desktop computers, consumer electronics, card-reader equipment, printers, storage accessories, and embedded USB peripherals. Because the controller consolidates hub and media-card functions, it can reduce the number of separate interface devices required in a compact system. Designers must still account for USB signal routing, connector protection, supply decoupling, card-detect wiring, and the exposed thermal pad when laying out the PCB. For USB2642-I/ML designs, confirm the exact pin functions, electrical limits, reference circuitry, and supported media details against the Microchip datasheet before release. USB high-speed pairs require controlled impedance and careful return-path continuity; card-interface traces should be kept away from noisy switching nodes. The part is not a general-purpose power semiconductor, so a Safe Operating Area chart is not applicable. This page combines the verified manufacturer and distributor information with package, application, procurement, and replacement guidance. It is intended to help engineers identify whether the USB2642-I/ML matches a USB hub plus flash-media architecture before committing the 48-QFN footprint to a PCB layout.

The manufacturer datasheet identifies USB 2.0 high-speed operation, support for eMMC, and sustained flash transfer rates exceeding 35 MB/s. The available part also lists I2C, SPI, and USB interfaces, providing configuration and connectivity options for embedded host systems. The USB2642 architecture is intended to place a USB host interface, downstream-port control, flash-media access, and supporting digital interfaces in one surface-mount IC. Its 48-QFN package provides a compact 7 mm × 7 mm footprint, but the exposed thermal pad requires careful PCB layout and adequate copper for heat dissipation. The -I ordering designation identifies the industrial -40°C to +85°C operating range shown in the comparison data. Typical uses include multifunction printers, set-top boxes, digital media systems, industrial HMI panels, and compact embedded USB systems that need both peripheral expansion and flash-card access. In such systems, the controller can connect storage media to an existing USB host while presenting two downstream USB ports for peripherals, reducing component count relative to separate controllers. The primary design consideration is power and signal integrity. Layout must preserve USB differential-pair routing, provide the decoupling and exposed-pad thermal structure required by the datasheet, and account for downstream-port current requirements. Designers should also verify card-format support, host-driver compatibility, firmware configuration, and connector protection before committing the USB2642T-I/ML to a new design. This page consolidates verified distributor pricing, package and interface details, manufacturer documentation, and a practical assessment of the limited directly verifiable drop-in alternatives.

The verified device data identifies USB 2.0 low-, full-, and high-speed operation, I2C and SPI interfaces, USB hub functionality, and flash-media controller functionality. The 48-QFN package provides a high pin count for integrated USB and storage connectivity, while the exposed pad supports thermal management on a suitably designed PCB. The exact supported media formats, electrical limits, operating-temperature range, and complete pin assignment are not provided in the supplied search data and must be confirmed from the manufacturer datasheet. Typical implementation places the USB2642T/ML between a USB host controller and downstream USB ports, with flash-media interfaces serving external storage devices. Firmware must configure the hub and media-access functions, while the host system supplies reference, clock, power, and I2C or SPI control. Designers should follow Microchip's USB routing, impedance, decoupling, and exposed-pad guidance rather than treating the QFN footprint as a generic package. The principal design consideration is signal integrity. USB high-speed edges require controlled impedance, short routing, continuous return paths, minimized stubs, and careful separation from noisy power and digital clocks. The exposed thermal pad must be connected to the intended ground or thermal plane according to the datasheet land pattern, and adequate decoupling must be placed close to the supply pins.

The device is housed in a 64-pin QFN (JZX) 9x9 mm package with exposed thermal pad, designed for surface mount desktop and notebook PC applications. The industrial temperature grade (-40C to +85C) makes the USB2660I variant suitable for non-consumer embedded use cases where the commercial-grade USB2660 is insufficient. A USB 2.0 Hi-Speed hub controller is a category of USB peripheral that aggregates multiple downstream ports and card-reader functions behind a single upstream port, while a flash media controller is a class of storage interface IC that bridges a host processor to removable flash memory cards using standardized protocols such as SD, MMC, and MSPro. The USB2660I sits at the intersection of these two product types, forming part of the broader USB interface IC hierarchy: USB peripheral controller -> USB hub controller -> combo hub + media reader -> Microchip USB264x/2660 family. This combination reduces PCB area, BOM count, and design complexity for system integrators that would otherwise need a separate hub chip and card-reader chip. Key features of the USB2660I-JZX-03 include 2 downstream USB 2.0 Hi-Speed ports, an internal transaction translator for mixed-speed USB environments, multi-format flash card support with dual SD interfaces, integrated card power FETs, on-board 24 MHz crystal driver, and USB-IF certified hub silicon. The chip is USB 2.0 compliant and supports Suspend and low-power modes per the USB specification. Programmable through an external I2C EEPROM, the device enables custom vendor/product IDs, string descriptors, and manufacturer-specific behavior. Internally the USB2660I uses Microchip's proven UTMI+ compliant physical layer and a hardened Hi-Speed USB 2.0 hub topology that delivers industry-leading data throughput in mixed-speed environments where some downstream devices run at Full-Speed (12 Mbps) and others at Hi-Speed (480 Mbps). The integrated media controller supports USB Mass Storage class and SDIO bridging, enabling SDIO peripherals to enumerate over USB with custom firmware. Typical applications include desktop and notebook PCs, multi-function printers with card reader slots, docking stations, set-top boxes, and industrial panel PCs that expose SD card slots and multiple USB ports to end users. Designers use the USB2660I-JZX-03 to consolidate USB expansion and media reading onto a single 9x9 mm QFN. When designing with the USB2660I-JZX-03, allocate at least four PCB layers for clean USB signal routing, route the differential DP/DM pair as a 90-ohm impedance-matched pair, and provide a local 0.1 uF decoupling cap adjacent to every power pin. The exposed thermal pad must be soldered to a contiguous ground pour to meet USB-IF Hub Certification thermal-rise limits.

USB3320C-EZK - Hi-Speed USB 2.0 ULPI Transceiver | Microchip
USB3320C-EZK

USB3320C-EZK - Hi-Speed USB 2.0 ULPI Transceiver | Microchip

The Microchip USB3320C-EZK is a highly integrated full-featured Hi-Speed USB 2.0 transceiver built on the proven ULPI (UTMI+ Low Pin Interface) standard, housed in a 32-pin QFN (5x5 mm) package. It supports 480 Mbps High-Speed and 12 Mbps Full-Speed USB signaling, operates from a single 3.3 V supply with on-chip 1.8 V LDO regulator, and provides up to +30 V VBUS ESD protection on the USB connector side. A USB 2.0 transceiver (also called a PHY) is the physical-layer analog block that sits between a digital SoC's ULPI/UTMI link and the differential DP/DM lines of a USB connector. It handles HS chirp, packet detection, serializer/deserializer, and clock recovery, while leaving link-layer protocol to the host controller. Within the system hierarchy, the USB3320C-EZK is a peripheral controller companion IC: SoC (application processor) -> ULPI link -> USB3320 PHY -> DP/DM -> USB connector. This split architecture lets designers pair an inexpensive PHY with any SoC that exposes ULPI pins (NXP i.MX, ST STM32, Xilinx Zynq, TI Sitara). Key electrical characteristics include 480 Mbps Hi-Speed data rate, internal 1.8 V regulator eliminating external LDO, integrated 45 ohm HS termination resistors (no external Rs needed), 8-bit single-data-rate ULPI interface with 60 MHz reference clock, and integrated USB charger-detection hardware. The device is USB 2.0 specification compliant, USB Battery Charging v1.2 capable, and OTG-ready via the ID pin. The architecture uses a 60 MHz reference clock input (REFCLK) generated by the SoC, an internal PLL multiplies to 480 MHz for HS operations. A digital state machine handles UTMI/ULPI command interpretation, while the analog block performs line termination, current-mode driver bias, and disconnect detection. The chip supports both host and peripheral roles. Typical applications include USB 2.0 device/host ports on single-board computers, OTG ports on industrial tablets, automotive infotainment USB interfaces, medical device USB ports, and 5G/LTE modem modules with USB 2.0 diagnostic channels. Designers favor the USB3320C-EZK over UTMI-only PHYs because ULPI slashes pin count to 12 versus UTMI's 30+. When designing with this device, maintain 90-ohm differential impedance on DP/DM traces to the connector, place decoupling capacitors on VDD33/VDD18/VBAT as close as possible to the IC, and ensure the REFCLK signal has less than 50 ps jitter to pass USB compliance. Do not omit the ID pin pull-up for OTG or charger-detection operation.

USB3803

USB3803 - 3-Port USB 2.0 Hi-Speed Hub Controller | Microchip

The Microchip USB3803 is a three-port USB 2.0 Hi-Speed hub controller optimized for portable, battery-powered embedded systems, integrating BC 1.1 charger detection, flexible internal power regulators, and a 25-ball WLCSP package. It connects to an upstream port as a Full-Speed or Hi-Speed hub and supports Low, Full, and Hi-Speed downstream devices on all enabled ports. The device targets tablets, smartphones, and other mobile platforms where small footprint, low standby current, and minimal BOM are critical design constraints. A USB hub controller is a dedicated interface IC that aggregates multiple downstream USB ports behind a single upstream port, handling transaction translation, port power control, and suspend/resume signaling. In the broader USB-IF taxonomy, hubs sit between hosts (root hubs inside PC chipsets) and peripherals, implementing Chapter 11 of the USB 2.0 specification. The USB3803 belongs to the "embedded hub" sub-category, optimized for integration into battery-powered devices rather than stand-alone retail hubs. Key features include 480 Mbps Hi-Speed upstream support, integrated USB-IF Battery Charging 1.1 detection on the upstream port, integrated 5V-to-3.3V and 1.8V regulators, a serial slave (I2C) interface for status/configuration, and ultra-low standby and bypass current modes. The WLCSP-25 package measures only 2.0 x 2.0 mm, enabling placement on space-constrained mobile mainboards. Microchip's Bypass mode (USB3803C variants) reduces quiescent current to single-digit microamperes when the host is off, directly extending battery life. Architecturally, the USB3803 integrates a Hi-Speed UTMI/ULPI-less PHY, a serial interface engine (SIE), per-port transaction translators, and the charger-detection analog block. The on-chip regulators remove the need for external LDO components when powered from a single 5V VBAT rail, further shrinking BOM count. The I2C serial slave interface exposes charger-status and configuration registers, allowing the application processor to query attach type, port power status, and override default settings. Typical applications include tablets and 2-in-1 laptops requiring one USB-A expansion port, smartphone accessories with OTG-to-host bridging, portable medical devices, and embedded infotainment head units. The charger-detection block also enables the device to act as a charger-sensing front-end, reporting Standard Downstream Port (SDP), Charging Downstream Port (CDP), or Dedicated Charging Port (DCP) classification back to the application processor over I2C. When designing with this part, allocate adequate PCB area under the WLCSP for the exposed die pad and route the 90-ohm differential USB pairs with controlled impedance. Microchip's USBCheck online design review service is available free of charge to qualified customers using the USB3803 in production designs.

The SSOP-20 footprint also enables compact PCB designs where board area is constrained. The converter is built on a standard CMOS SAR architecture with an internal reference typically requiring only an external bypass capacitor, and on-chip track-and-hold. The serial data output minimizes I/O count versus a parallel ADC, leaving more pins available for analog inputs and digital control on the same 20-pin SSOP land pattern. Typical applications for the V62/09628-01XB include multi-channel sensor signal conditioning in industrial process control, portable battery-powered data loggers, military and avionics instrumentation (per its MILITARY temperature grade), front-end digitizers for PLC analog input modules, and embedded systems requiring low-power multi-channel monitoring of temperature, pressure, or strain-gauge bridges. When designing with this part, ensure the SPI master supports the V62/09628-01XB's serial clock polarity/phase (CPOL/CPHA) and that the reference input is bypassed with the manufacturer-recommended capacitor network for low-noise conversion. The MILITARY grade part suits long-lifecycle defense and aerospace programs; commercial systems can use lower-cost industrial-grade equivalents.

Typical applications include data center networking (600 GbE switches), storage controllers, wired communications (400G connectivity), and high-performance embedded computing. The device's high-bandwidth memory interfaces and transceivers enable it to handle massive data streams with low latency. When designing with the VM2152, careful attention must be paid to power delivery and thermal management due to its high performance. The 1369-FCBGA package requires a robust PCB layout with adequate decoupling and thermal vias. Additionally, the Processing System Wizard IP should be used for PS configuration, as the traditional CIPS IP is not supported on this device.

VNC1L-1A - Vinculum Embedded USB Host/Slave Controller, 48-LQFP | FTDI

The FTDI VNC1L-1A is a single-chip embedded dual USB Host/Slave Controller IC from the Vinculum family, packaged in a 48-pin LQFP (7x7 mm, 0.5 mm pitch). It integrates two USB 2.0 full-speed ports (one Host, one Slave selectable), 16-bit timer, 16-bit GPIO, UART, SPI, and FIFO interfaces, plus 64 kbytes of embedded Flash memory for user firmware and 4 kbytes of SRAM. The device operates from a single 3.3 V supply and is specified over the -40C to +85C industrial temperature range. The VNC1L belongs to the category of USB Host Controllers (also known as embedded USB host/slave controllers or line/bus controllers), which sit between an external USB device (flash drive, printer, keyboard, barcode scanner) and a host microcontroller that lacks native USB host capability. Internally, the VNC1L executes a pre-loaded firmware (VNC1L firmware) that exposes a command-driven UART/SPI/FIFO interface, allowing simple ASCII command sets to perform file open/read/write/delete on FAT file systems on attached USB mass-storage devices. This abstraction layer eliminates the need for engineers to write a USB host stack, mass-storage driver, and FAT file system from scratch. Key features documented in the FTDI datasheet revision 2.02 (document FT_000030) include dual USB 2.0 full-speed (12 Mbps) ports, integrated 3.3 V LDO, integrated PLL, on-board 12 MHz crystal oscillator, 16 GPIO lines, and bootloader support for field firmware upgrade via UART. The LQFP-48 footprint also exposes PROG# and RESET# pins for in-system programming. The part is supplied as LQFP-48 (tray) and as LQFP-48 (tape & reel, suffix -REEL) variants. Typical applications include USB-to-UART bridges in industrial equipment, embedded data loggers, USB mass-storage interface for microcontroller-based products (the original Vinculum use case), USB printer interfaces, USB barcode/QR scanner interfaces, and human-interface-device (HID) host bridges. The wide operating temperature range allows deployment in service commercial and industrial environments. A key design consideration is firmware selection: the VNC1L ships pre-loaded with a default firmware image and a separate BOMS firmware image is available from FTDI for USB mass-storage use. Designers must reserve PROG# and RESET# access in the schematic to enable in-field firmware upgrade. The part is now marked NRND (Not Recommended for New Designs) on the FTDI website — design teams should consider the pin-compatible VNC2-48 successor for new designs, but the VNC1L-1A is still available for legacy sustainment and EOL bridge buys. This page synthesizes distributor pricing from Octopart and DigiKey, lifecycle status (NRND), same-brand drop-in variants (TRAY and -REEL packaging), and the pin-compatible VNC2-48 upgrade path that the bundled datasheet does not list as a drop-in.

VS1073A-L - MP3/Ogg/FLAC Audio Codec LQFP-48 | VLSI
VS1073A-L

VS1073A-L - MP3/Ogg/FLAC Audio Codec LQFP-48 | VLSI

The VLSI Solution VS1073A-L is an MP3 / Ogg Vorbis / FLAC / WAV encoder and audio codec IC housed in a surface-mount LQFP-48 package. It combines a stereo DAC, a stereo ADC, and a high-performance DSP core on a single die, and communicates with a host MCU over an SPI bus. Supporting product, with GPIO, I2S, SPI, and UART interfaces. An audio codec IC is a mixed-signal integrated circuit that converts analog microphone or line-level audio into digital samples (ADC path) and converts stored or received digital audio back into analog signals for headphones or line output (DAC path). Modern codecs such as the VS1073A-L integrate a hardware DSP accelerator so that compressed formats like MP3 and Ogg Vorbis, as well as FLAC and WAV PCM, can be decoded or encoded on-chip without consuming the host MCU's CPU cycles. Key features include on-chip encoding and decoding of MP3, Ogg Vorbis, FLAC, WAV PCM, and G.711/G.722 voice formats; a stereo 16-bit DAC and stereo 16-bit ADC; separate analog AVDD and digital CVDD supplies; a high-level SCI (Serial Control Interface) command set; and a dedicated serial audio data (SDI) input that streams compressed bitstreams to the decoder. The part runs from a 6.144 MHz fundamental-mode crystal or external clock and supports variable sample rates from 8 kHz to 48 kHz at the analog interfaces. The VS1073A-L uses a 6.144 MHz reference clock and a separate internal PLL to derive the audio sample-rate clocks. It exposes I2S in addition to the parallel/DSP serial audio data path, which simplifies connection to external DACs, ADCs, or digital speaker amplifiers. The 1.25 V CVDD rail must be generated externally (the VS10xx comparison app note recommends a dedicated LDO for future-proofing). Typical applications include MP3 player modules, Ogg Vorbis / FLAC playback docks, voice recorders, two-way intercom panels, USB audio adapters, and embedded audio playback in industrial HMIs. The combination of on-chip encoding and decoding makes it a fit for products that must both record and play audio. When designing with this part, ensure the CVDD rail is stable before AVDD is applied, route the analog grounds separately back to the regulator, and keep the 6.144 MHz crystal traces short to avoid jitter that would otherwise degrade the DAC SNR. This page synthesizes distributor pricing, drop-in VS10xx family alternatives, and practical design notes not found in the bare manufacturer datasheet, giving engineers a one-stop reference for sourcing and designing with the VS1073A-L.
