RC28F128P33B85B - 128Mbit NOR Flash, 52MHz, 85ns, 64-EasyBGA | Intel/Altera
MPN: RC28F128P33B85B ✗ پایان تولیدRC28F128P33B85B نمای کلی
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.

کاربردهای معمول
RC28F128P33B85B مناسب است برای 6 کاربردs: Embedded Boot ROM for Networking Equipment, Industrial Control Firmware Storage, Automotive Infotainment Code Storage, Legacy Parallel-Interface Embedded Designs, Firmware Update Storage with Redundancy, Test and Measurement Equipment Data Logging.
Embedded Boot ROM for Networking Equipment
The RC28F128P33B85B is well suited as the boot ROM in routers, switches and base stations because its 85 ns random access and 52 MHz synchronous burst mode support deterministic execute-in-place (XIP) at typical CPU clock speeds. The 16 Mbyte density stores full bootloaders plus secondary recovery images, and the read-while-write architecture enables firmware updates without taking the system offline. Its 2.5 V/3.3 V supply matches the legacy parallel bus found in many PowerPC and MIPS networking SoCs, eliminating level-translation overhead.
پیشنهادی
Industrial Control Firmware Storage
In PLCs, HMIs and motor controllers, the RC28F128P33B85B stores application firmware plus configuration data with industrial -40C to +85C temperature grading. Its 33-bit on-die hardware ECC provides production-grade reliability for long-life industrial equipment, and the EasyBGA-64 (8x10 mm) compact footprint fits within densely populated control boards. Read-while-write allows live firmware patching without halting the control loop, which is critical for continuous-process industries.
پیشنهادی
Automotive Infotainment Code Storage
Although the standard RC28F128P33B85B is industrial-grade (-40C to +85C) rather than AEC-Q100 qualified, it has historically been used in non-safety-critical automotive infotainment and telematics applications where its 128 Mbit density stores navigation maps, media assets and application code. Its parallel x16 bus delivers sufficient throughput for streaming audio/video metadata, and the EasyBGA-64 package withstands automotive thermomechanical stress. For safety-critical ADAS systems, an AEC-Q100 qualified alternative is required.
پیشنهادی
Legacy Parallel-Interface Embedded Designs
Designers maintaining x86 embedded platforms, legacy PowerPC designs, or older MIPS controllers benefit from the RC28F128P33B85B's standard CFI parallel interface and multiplexed address/data bus. The 85 ns access time accommodates 25-40 MHz host bus frequencies without wait states, and the JEDEC CFI query protocol allows the bootloader to identify the part without proprietary commands. This makes it ideal for long-lifecycle designs in medical, defense and industrial automation where board respins are expensive.
پیشنهادی
Firmware Update Storage with Redundancy
The RC28F128P33B85B's read-while-write feature makes it ideal for A/B firmware partition schemes where one bank holds the active image and another receives the update. The 128 Mbit density accommodates two complete 8 Mbyte firmware images plus a non-volatile configuration block. The 33-bit ECC engine corrects bit errors induced by long retention or radiation, which is essential for medical and aerospace systems where data integrity is non-negotiable.
پیشنهادی
Test and Measurement Equipment Data Logging
Oscilloscopes, spectrum analyzers and data-acquisition systems leverage the RC28F128P33B85B for non-volatile capture storage where 128 Mbit holds hundreds of waveform records. Its 52 MHz synchronous burst read mode enables fast recall of stored captures to the display processor, and the hardware ECC preserves calibration constants against bit rot over the equipment's multi-decade service life. The industrial temperature rating suits bench and field-deployed instruments.

یادداشت‌های طراحی
EasyBGA-64 packages require PCB pad design per JEDEC BGA guidelines - use NSMD (non-solder-mask-defined) pads with 0.5 mm diameter and 1.0 mm pitch. Vias-in-pad with filled and plated-over copper are recommended for the inner balls to improve thermomechanical reliability and signal integrity for the multiplexed address/data bus. Reference the Intel StrataFlash P33 hardware design guide for the recommended 4-layer stackup.
The 52 MHz synchronous read mode requires series damping resistors (22-33 ohm) on DQ[15:0] near the flash to suppress reflections from the host memory controller. Trace length matching within 100 mils across the byte lane is essential. Place 0.1 uF X7R decoupling capacitors adjacent to every VCC and VCCQ ball, with bulk 4.7 uF tantalum or ceramic on each supply rail.
Do not assume RC28F128P33B85B software commands are pin-compatible with older P30 or Numonyx M28W parts - the command set, status register layout and CFI query structure changed in the P33 generation. Reprogram your flash translation layer (FTL) or device driver using the latest Intel specification upgrade command set. Failure to do so can corrupt blocks or yield unreliable ECC reports.
During program and erase operations, VCC current can spike to 50 mA per bank. Decoupling must hold VCC within 5% during these transients. Add a 10 uF bulk capacitor per EasyBGA device plus 0.1 uF bypass on every supply pin. Read-while-write operations require both banks to have independent decoupling; do not share bulk capacitors between parallel-mounted flashes.
