A29010 Series 128K X 8 Bit CMOS 5.0 Volt-only, Preliminary Uniform Sector Flash Memory
The A29010 series provides 128 Kbytes of non‑volatile storage organized as four 32 KB sectors. It operates from a single 5.0 V supply, eliminating the need for a separate VPP voltage, and supports in‑system programming and erase. The device features toggle bits for program/erase status, sector protection, and an embedded erase algorithm that can erase any combination of sectors or the entire chip.
Typical applications include microcontroller‑based systems requiring fast access (55 ns‑90 ns), low standby current (≈1 µA), and long data retention (20 years at 125 °C). The part is offered in 32‑pin PLCC, TSOP (forward type) and PDIP packages and is pin‑compatible with JEDEC single‑power‑supply flash standards.
