A29001/290011 Series 128K X 8 Bit CMOS 5.0 Volt-only, Preliminary Boot Sector Flash Memory is a 5.0V voltage flash memory chip, with read and write operations voltage of 5.0V±10%, and read time of 55/70/90 (max.).
The AMIC A29001/A290011 series provides 128 K‑bit (131,072 bytes) CMOS flash memory operating at a single 5.0 V supply. It offers flexible sector architectures (8 KB, 4 KB × 2, 16 KB, 32 KB × 3) with full chip erase, sector protection, and embedded erase/program algorithms. The device is available in 32‑pin PLCC, TSOP, and PDIP packages and can be programmed in‑system without a high‑voltage VPP.
Key functions include separate chip‑enable, write‑enable, and output‑enable controls, hardware reset, data‑polling status bits, and standby mode for low power consumption. The memory supports up to 100,000 program/erase cycles per sector and retains data for 20 years at 125 °C. Electrical ratings, timing diagrams, and command sequences are detailed for designers.
