RC28F128P33B85B

RC28F128P33B85B - 128Mbit NOR Flash, 52MHz, 85ns, 64-EasyBGA | Intel/Altera

The Intel/Altera RC28F128P33B85B is a 128-Mbit parallel NOR Flash memory device organized as 8M x 16, built on Intel's StrataFlash Embedded Memory technology and housed in a 64-ball EasyBGA (8x10 mm) package. It supports 2.5V/3.3V dual-voltage operation, offers 52 MHz CFI (Common Flash Interface) read throughput with 85 ns initial access time, and provides hardware-accelerated 33-bit ECC for reliable code and data storage. A NOR Flash memory is a non-volatile storage technology that provides random read access at byte or word granularity, in contrast to NAND Flash which is read in large pages. NOR Flash retains code directly executable in-place (XIP), making it the historical choice for boot ROM, firmware storage, and embedded systems where deterministic read latency matters. Within the memory hierarchy, NOR Flash sits above NAND Flash and below SRAM/DRAM, trading higher density for fast random reads and long-term data retention. Key features of the RC28F128P33B85B include 128 Mbit (16 Mbyte) density, x16 data bus, Common Flash Interface (CFI) for vendor-independent identification, 33-bit hardware ECC, and a uniform 64-Kbyte symmetric block architecture with configurable read-while-write (RWW) capability. The P33 process technology delivers lower power consumption and faster program/erase times than earlier Numonyx/Intel P30 devices. This part supports simultaneous read-while-write operations, allowing the host CPU to fetch instructions from one bank while another bank is being programmed or erased. The EasyBGA-64 (8x10 mm) package offers a compact footprint suitable for space-limited embedded designs while exposing the full multiplexed address/data bus needed for legacy parallel interfaces. Typical applications include embedded boot ROM for networking equipment, industrial control firmware storage, automotive telematics and infotainment code storage, and legacy parallel-interface designs that require deterministic read latency. The 52 MHz synchronous burst-read mode also enables higher-throughput data streaming. When designing with this device, ensure the host platform supports the legacy CFI query protocol and the 33-bit hardware ECC engine for production-grade reliability. Designers transitioning from older Numonyx/Intel P30 devices must verify pinout compatibility, as the EasyBGA ball map differs from earlier TSOP packaging. This page synthesizes distributor pricing from LCSC, DigiKey Marketplace and Octopart, drop-in package-compatible alternatives from the same P33 family, and practical design considerations not consolidated in the manufacturer datasheet.

It functions as a line driver and level shifter IC for IO-Link communication, integrating push-pull output drivers with RDS(ON) below 2.5 ohm and tolerating supply voltage transients up to 60 V. The part supports both IO-Link master and device roles, making it suitable for sensor/actuator nodes and master-side communication. An IO-Link physical layer (PHY) transceiver is a dedicated interface IC that implements the IEC 61131-9 single-drop digital communication interface for industrial sensors and actuators. The PHY sits between the microcontroller UART/IO-Link stack and the 3-wire sensor cable (L+, L-, CQ), handling 24 V line drive levels, reverse-polarity protection, surge suppression, and the 8 mA / 16 mA / 24 mA current-sinking modes defined by the IO-Link standard. It belongs to the hierarchy: IO-Link PHY -> industrial transceiver -> interface IC -> integrated circuit -> semiconductor. Key features include configurable CQ output stages (push-pull, high-side, low-side), integrated reverse-polarity blocking on the supply pin, 60 V transient robustness on L+, an OWI (One-Wire Interface) configuration channel for parameter storage, and CMOS mixed-signal technology that supports 4.5 V to 30 V supply operation. The 12-DFN package offers a compact 3x3 mm footprint for space-constrained sensor heads. The RH4Z2501 includes internal protection features that simplify the external TVS/Schottky network typically required by IO-Link designs: over-temperature shutdown, under-voltage lockout, and reverse-polarity handling. The OWI channel allows the MCU to write configuration and identification data to on-chip non-volatile memory during end-of-line commissioning. Typical applications include IO-Link sensor signal conditioning in factory automation, IO-Link master communication modules, 24 V industrial valve and actuator drivers, and PLC digital I/O cards implementing single-drop IO-Link ports. When designing with this part, place the decoupling capacitor (10 V on L+) as close to the pin as possible and keep the CQ trace short to minimize radiated EMI. Configure the OWI address during manufacturing only - do not reconfigure OWI in the field without a controlled procedure.

RK3288

RK3288 - Quad-Core Cortex-A17 SoC | Rockchip | BGA-636

The Rockchip RK3288 is a low-power, high-performance 32-bit quad-core application processor built around four ARM Cortex-A17 cores with a separately clocked NEON SIMD coprocessor and an ARM Mali-T764 GPU, packaged in a 636-ball BGA. It is designed for mobile phones, personal mobile internet devices (PMID), and other digital multimedia applications, integrating CPU, GPU, multimedia, memory controller, and peripheral I/O into a single SoC. A quad-core application processor (AP) is a system-on-chip that integrates multiple CPU cores, a graphics processor, memory interfaces, display controllers, and standard peripherals (USB, SDIO, I2C, SPI, UART, Ethernet, HDMI, LVDS, MIPI) on a single die. In a system architecture, the AP sits between power management ICs (PMICs), DRAM (LPDDR2/LPDDR3/DDR3), and the display/camera subsystems. The RK3288 belongs to a broader family of Rockchip ARM APs and is part of the Cortex-A17 generation that targeted Android tablets, set-top boxes, Chromebooks, and digital signage during the mid-2010s. Key features include quad-core ARM Cortex-A17 up to 1.8 GHz, Mali-T764 GPU with OpenGL ES 3.1 support, hardware-accelerated 4K H.264/H.265 video decode, HDMI 2.0 output up to 4K@60Hz, dual-channel 32-bit LPDDR3/DDR3/LPDDR2 interface, MIPI DSI and LVDS display outputs, USB 2.0, SD/MMC, eMMC 5.0 support, and integrated audio codec with SPDIF/I2S. The chip supports Android 5.x/6.x and Linux kernels, making it a versatile multimedia AP for consumer and embedded OEMs. The RK3288 uses a 28 nm HKMG CMOS process, which balances performance with reasonable power consumption. Its quad-core Cortex-A17 out-of-order design delivers significantly higher single-threaded performance than the Cortex-A9 predecessor (RK3188) and enables efficient multitasking. The Mali-T764 GPU supports modern graphics APIs, while the 4K hardware codec block offloads video decode from the CPU cores. Typical applications include Android tablets, Chromebooks, digital signage, smart home control panels, set-top boxes, industrial HMI terminals, and embedded kiosks. Designers choose the RK3288 when they need a mature quad-core Cortex-A17 SoC with strong multimedia capabilities and broad Linux/Android BSP support. When designing with the RK3288, pay attention to PCB layout for the BGA-636 footprint - it requires microvia / HDI PCB technology for reliable BGA escape routing. Thermal management is critical because the SoC can dissipate 2 to 5 W under full CPU+GPU+4K decode load. Use a multi-layer PCB with a continuous ground plane under the BGA and provide adequate copper thermal relief around the package. Validate the PMIC compatibility (e.g., RK808 or ACT8846 family) and DRAM timing margins before committing to volume production.

RK3368

RK3368 - Octa-Core 64-bit ARM Cortex-A53 SoC | Rockchip

The Rockchip RK3368 is a low-power, high-performance 64-bit application processor integrating an octa-core ARM Cortex-A53 CPU cluster with separately clocked NEON coprocessors and an ARM Mali-T720MP2 GPU, targeted at smart TV boxes, OTT streaming devices, set-top boxes, and personal mobile internet devices. The part is manufactured in a 28 nm HPC process, supports up to 1.5 GHz core frequency, integrates 4K H.265/H.264 hardware decoding, HDMI 2.0 output up to 4K@60 Hz, and dual-channel DDR3/DDR3L/LPDDR2/LPDDR3 memory controllers. The RK3368 ships in a 19 mm x 19 mm BGA-453 package (0.8 mm pitch) and is specified for commercial-grade operation at 0 C to +80 C ambient. What is an application processor SoC? An application processor SoC (System-on-Chip) integrates the CPU, GPU, memory controller, video decoder/encoder, display pipeline, and connectivity peripherals onto a single silicon die. In the broader taxonomy: SoC -> application processor -> microprocessor unit (MPU) -> semiconductor. Rockchip positions the RK3368 in its 64-bit octa-core family below the RK3399 (big.LITTLE A72+A53) and above the entry-level RK3328 (quad-core A53).

The integrated Cortex-A53 cores provide 2-3x the performance-per-watt of the previous-generation Cortex-A7 used in the RK3288. The RK3368 architecture uses a single homogeneous octa-core cluster with coherent L2 cache, simplifying software scheduling compared to big.LITTLE designs. The 28 nm process keeps idle power low, while the integrated LPDDR3 controller with 32-bit width and 800 MHz clock provides up to 6.4 GB/s memory bandwidth suitable for 4K video decode. Typical applications include 4K Android TV boxes, OTT streaming sticks, smart signage players, industrial HMI panels, and education tablets. The Cortex-A53's power efficiency also makes the part suitable for fanless enclosures. Design consideration: the RK3368 requires careful 4-layer or 6-layer PCB stack-up with matched-length DDR3 traces and a robust PMIC (RK806 or compatible). LPDDR3 routing demands 100 ohm differential impedance; deviations will cause read/write errors at high temperatures.

RMLV0816BGSD-4S2 - 8Mb Low-Power SRAM 512Kx16 45ns TSOP | Renesas

The Renesas RMLV0816BGSD-4S2 is an 8-Mbit Advanced Low-Power Static RAM organized as 524,288-word x 16-bit (512K x 16), fabricated on Renesas' high-performance Advanced LPSRAM process technology. The device is offered in a 52-pin TSOP-II package and delivers 45 ns parallel access time, making it suitable for low-power embedded systems that require fast random read/write cycles. An LPSRAM (Low-Power SRAM) is a class of asynchronous static random-access memory that retains data without refresh and is optimized for ultra-low standby current consumption. LPSRAMs occupy a distinct position in the memory hierarchy: faster than NOR flash, lower pin-count than DRAM (no refresh controller required), and dramatically lower quiescent current than legacy SRAM - typically in the microamp range. They are widely used as working RAM, data buffers, and backup-memory companions to MCUs in industrial and consumer designs. Key features of the RMLV0816BGSD-4S2 include a single 2.7 V to 3.6 V supply, 45 ns address access time, fully static asynchronous operation (no clock required), TTL-compatible I/O, three-state outputs, and an operating temperature range of -40 C to +85 C for the industrial grade variant. The device supports byte-wise control via /LB and /UB pins for 8-bit/16-bit flexible access, plus standard /CS, /OE, and /WE control signals. Advanced LPSRAM technology achieves low standby current while maintaining fast access, suitable for battery-backed applications. Architecturally, the RMLV0816BGSD-4S2 employs a 6-transistor (6T) CMOS memory cell array with on-chip sense amplifiers and self-timed write circuitry. The advanced LPSRAM process allows smaller cell size while preserving the low-leakage characteristics that define the family. Internal address latches and a common I/O bus enable efficient 8-bit (byte) and 16-bit (word) access without external logic. Typical applications include industrial controls, factory automation PLCs, networking line cards, portable instrumentation, medical devices, POS terminals, and any battery-backed data-logging system requiring reliable byte-wide or word-wide buffering. Designers often pair this LPSRAM with low-power MCUs such as Renesas RX or RA families for energy-harvesting or sleep-mode designs. A key design consideration is the decoupling strategy: place a 0.1 uF ceramic bypass capacitor within 5 mm of the VCC pin and a 10 uF bulk capacitor on the supply rail. Avoid driving the I/O bus faster than the rated access time to prevent bus contention during read/write transitions.

RMLV0816BGSD-4S2#AC0

RMLV0816BGSD-4S2#AC0 - 8Mb Advanced LPSRAM | Renesas | TSOP-II 52

The Renesas RMLV0816BGSD-4S2#AC0 is an 8-Mbit advanced low-power static RAM organized as 524,288-word × 16-bit (or 1M × 8), fabricated on Renesas's high-performance Advanced LPSRAM process. The device operates from a single 2.4V to 3.6V supply, provides 45 ns access time, and ships in a 52-pin TSOP-II surface-mount package. It is part of the RMLV0816BGSD family aimed at embedded systems that need byte-wide or word-wide battery-backed memory. A low-power SRAM (LPSRAM) is a type of volatile static random-access memory that retains data without refresh cycles and consumes very low standby current, making it the preferred choice for battery-powered or always-on subsystems. Within the broader memory hierarchy, LPSRAM sits between small on-chip MCU SRAM and larger DRAM, filling the role of fast, byte-addressable working memory. Compared to DRAM, LPSRAM eliminates the need for periodic refresh, simplifies board design, and improves immunity to bit errors caused by particle hits, at the cost of lower density per die. Key features of the RMLV0816BGSD-4S2 include a wide 2.4V–3.6V single-supply range, 45 ns access time, byte-control via UB#/LB# pins for x16 operation, support for x8 / x16 bus width selection, and very low standby current. The 52-TSOP II footprint is the industry-standard pinout for 8-Mbit word-wide SRAM, allowing it to replace legacy parallel SRAMs from Cypress, ISSI, and Alliance on existing PCB layouts. The Advanced LPSRAM cell technology keeps active current low while delivering fast read/write cycles for data logging or boot-loader scratchpad use. Internally, the die uses a six-transistor (6T) SRAM cell with CMOS I/O, including a chip-enable (CE#), write-enable (WE#), output-enable (OE#), and upper/lower byte select (UB#/LB#) for flexible bus sizing. The wide voltage range is achieved through on-chip charge-pump-free regulation, so no external VCCQ or VPP rail is required. The 45 ns access time is sufficient for direct connection to most microcontrollers and low-end microprocessors without wait-state insertion at ≤33 MHz, which covers typical MCU-class applications. Typical applications for the RMLV0816BGSD-4S2 include industrial control data buffers, metering and instrumentation scratch memory, networking router packet buffers, automotive infotainment working memory, and battery-backed data retention when paired with an external supercapacitor or coin cell. The wide 2.4V–3.6V range also suits USB, Bluetooth, and Zigbee module working memory. When designing with this part, ensure that decoupling (0.1 µF + 10 µF bulk) is placed within 5 mm of VCC, and respect the data retention voltage (typically 2.0V) if you intend to operate from a battery backup rail. UB# and LB# must be tied low for full 16-bit access; leaving them floating introduces bus contention and increases standby current.

RMWV3216AGBG-5S2#AC0

RMWV3216AGBG-5S2#AC0 - 32Mb Advanced LPSRAM, 2Mx16, 55ns | Renesas

The Renesas Electronics RMWV3216AGBG-5S2#AC0 is a 32-Mbit Advanced Low-Power SRAM (LPSRAM) organized as 2,097,152 words × 16 bits, fabricated in Renesas's high-performance Advanced LPSRAM CMOS technology. It is offered in a 48-ball TFBGA package measuring 7.5 mm × 8.5 mm, operates from a single 2.7 V to 3.6 V supply, and delivers a 55 ns fast access time in parallel mode. The I-temperature grade (-40 °C to +85 °C) makes it suitable for industrial environments. An LPSRAM (Low-Power SRAM) is a class of asynchronous static random-access memory that retains data without refresh and offers dramatically lower active and standby current than conventional SRAM. LPSRAM sits in the broader memory hierarchy between volatile DRAM (which needs refresh and is dense) and true non-volatile memory (Flash/EEPROM, which is slow to write). Within Renesas's portfolio, Advanced LPSRAM targets battery-backed and energy-harvesting applications where every microwatt of quiescent current matters, while still delivering the byte-level random access that Flash cannot. Key features include very low standby current for battery-backup retention, a wide 2.7 V to 3.6 V single-rail supply range that simplifies power-tree design, common parallel SRAM interface pinout (CS, OE, WE, UB/LB byte enables) for drop-in replacement of legacy async SRAMs, and 3-STATE outputs for bus-sharing. The 48-ball TFBGA footprint is also substantially smaller than TSOP or SOJ packaging used by older 32-Mbit parallel SRAMs. Technically, the device uses a six-transistor (6T) CMOS memory cell array with on-chip address decoding and sense amplifiers, plus internal voltage generation for the memory core. The die is organized as 2M × 16 with separate upper-byte and lower-byte write enables (UB, LB), which simplifies 8-bit and 16-bit bus designs in the same socket. Power-saving features include automatic power-down when CS is deselected, plus data-retention modes down to 2.0 V for coin-cell backup. Typical applications include industrial metering and data loggers, factory automation controllers, point-of-sale terminals, automotive infotainment buffers, medical handheld instruments, networking line cards requiring fast read/write buffers, and battery-backed equipment such as e-meter or PLC retentive memory. The low standby current makes it attractive as a shadow RAM for systems that must preserve state through power loss. When designing with this part, follow the datasheet's decoupling guideline of a 0.1 µF ceramic capacitor placed within 5 mm of each VCC ball, plus a bulk 10 µF tantalum or ceramic on the supply rail. Place the device close to the host controller to keep the address/data bus traces short, since the 55 ns access time assumes modest capacitive loading.

RTAX1000S-1LG624V

RTAX1000S-1LG624V - 1M-Gate Rad-Tolerant FPGA | Microchip

The Microchip Technology RTAX1000S-1LG624V is a radiation-tolerant antifuse FPGA delivering 1,000,000 equivalent system gates with 12096 CLBs, 18144 logic cells, and up to 418 user I/Os, housed in a 624-ball ceramic column grid array (LG624) package. A radiation-tolerant FPGA is a field-programmable gate array engineered to survive the ionizing radiation and single-event effects encountered in orbital and deep-space environments. Unlike reprogrammable SRAM FPGAs, the RTAX-S family uses nonvolatile antifuse technology, in which permanent interconnects are formed at one-time programming. This eliminates configuration-storage vulnerabilities, gives true live-at-power-up operation, and makes the device a single-chip solution in the power management hierarchy of spacecraft avionics systems. Key features include one-time-programmable antifuse interconnect with no external configuration PROM, up to 540 kbits of embedded SRAM with optional EDAC protection, segmentable clock resources, chip-wide highway routing, and carry logic inherited from the commercial Axcelerator architecture. Total ionizing dose tolerance is 300 krad (functional) and 200 krad (parametric), with SEU rates below 1E-10 errors per bit-day. The CMOS architecture achieves a maximum combinatorial delay of 0.93 ns on the -1 speed grade. Embedded FIFO control logic and dual-port SRAM blocks support on-board data processing, telemetry formatting, and payload signal chains without external memory in many designs. Typical applications include satellite payload processing, spacecraft telemetry and command interfaces, radiation-hardened bus controllers, and Earth-observation instrument data acquisition where live-at-power-up behavior is mandated. Design consideration: because the device is one-time programmable, complete functional simulation and a prototyping pass on the pin-mapped commercial Axcelerator device via Microchip Extender boards or Aldec CG624 adaptor boards are strongly recommended before committing flight parts.

Unlike flash- or SRAM-based FPGAs, the RTAX-S/SL family uses antifuse programmable interconnect that is one-time programmed, providing live-at-power-up operation with no external configuration storage required. Key features include 1,000,000 system gates of capacity, embedded SRAM blocks with built-in FIFO control logic, segmentable clock resources, chip-wide highway routing, and dedicated carry logic for arithmetic chains. Because the configuration is locked into the antifuse fabric, the device is immune to configuration upsets that plague SRAM FPGAs, dramatically reducing SEU-driven system-level mitigation overhead. The RTAX1000SL is based on the commercial Axcelerator architecture, so designers can prototype on cost-effective Axcelerator devices and migrate using Microchip's footprint-compatible adaptor board methodology and EDIF netlist/pinout conversion flow described in the RTAX-S/SL datasheet. Typical applications include spacecraft avionics buses, satellite payload data processing, telemetry/command interfaces, and instrument control in low-Earth-orbit and deep-space missions where low power and single-chip form factor matter. A key design consideration: antifuse devices are one-time programmable, so functional verification (simulation and hardware prototyping on Axcelerator equivalents) must be completed before programming flight units.

Architecturally, the RTAX2000S is fabricated in a CMOS process and organizes its ~2 million gates across logic modules, embedded SRAM blocks, and I/O clusters. Designers implement radiation-hardening-by-design techniques at the system level, typically combining the RTAX-S fabric with external triple-module-redundancy (TMR) schemes supported by Microchip's Libero design suite and Hi-Rel mitigation flows. Typical applications include satellite payload processing, spacecraft bus control, telemetry and telecommand interfaces, and launch-vehicle avionics - anywhere complex logic must operate for years in orbit.

A radiation-tolerant FPGA (Field Programmable Gate Array) is a programmable logic device engineered to survive the ionizing radiation environments of space flight, including total ionizing dose (TID), single-event upset (SEU), and single-event latchup (SEL). Within the power hierarchy of spacecraft electronics, the RTAX-S family sits alongside rad-hard processors and memory as core onboard data-processing silicon, using anti-fuse programmable interconnect that is programmed once and remains stable under radiation. Key features of the RTAX2000S-CQ256PROTO include low-power consumption, true single-chip form factor, and live-at-power-up (LAPU) operation, which eliminates the need for an external configuration device. The PROTO variant shares the same functional characteristics as the space flight unit but ships in a non-hermetic package at a fraction of the cost, specifically for functional verification before committing to flight parts. Architecturally, the RTAX-S/SL family uses Microchip's Axcelerator-derived logic fabric with a sea-of-modules architecture combining C-cells, R-cells, and embedded SRAM/dedicated FIFO blocks, enabling high performance at densities up to four million equivalent system gates for space-based applications. Typical applications include satellite on-board data handling, spacecraft payload processing, telemetry and telecommand interfaces, and reprogrammable prototyping of RTAX-S flight designs. Designers often pair the PROTO device with Aldec prototyping adaptors that map ProASIC3E flash technology onto the CQ256 footprint for iterative functional verification. A key design consideration is that PROTO devices are non-hermetic and not radiation-screened, so they must never be flown; they exist solely for de-risking the flight design. Timing closure performed on PROTO silicon should be re-verified against flight-grade specifications.
