概要
Description
PC28F00AM29EWHA is a NOR-type flash memory device used to store firmware and other non-volatile data in embedded systems. It belongs to the PC28F00A family and is typically a parallel (8-bit) NOR flash part.
Key points:
- Capacity: around 1 Mbit (about 128 KB) in the common PC28F00A family variant.
- Interface/pinout: parallel 8-bit data bus; requires standard NOR flash control signals (CE, OE, WE) and address lines.
- Voltage: usually 3.0–3.6 V (3.3 V nominal).
- Operation: random-access reads; page/sector erase and byte/word programming with standard command sequences.
- Endurance and retention: typical erase/program cycles in the tens of thousands; data retention rated for many years.
- Package: commonly a mid-density TSOP/SOP-type 48-pin variant, but exact package depends on the lot/steering variant.
- Applications: firmware storage, boot ROMs, code and data storage in microcontroller or embedded designs.
Note: exact timings, speed grade, package, and endurance vary by revision. Always consult the official datasheet for precise specifications and pinout.
