Am28F020A is a 2 Megabit Flash memory organized as 256 Kbytes of 8 bits each. It features high performance, low power consumption, compatibility with JEDEC standard, and programmable erase.
The AM28F020A is a 2 Megabit (256 K × 8‑bit) CMOS flash memory that can be erased in‑system with a 12 V bulk erase voltage. It features embedded erase and program algorithms that simplify timing and verification, providing typical chip erase in five seconds and byte programming in four seconds at room temperature.
The device is offered in 32‑pin PDIP, PLCC, and TSOP packages and supports commercial, industrial, and extended temperature ranges. It uses standard TTL‑level control inputs, with separate chip‑enable (CE#) and output‑enable (OE#) pins, and includes latch‑up protection up to 100 mA.
