M29F002BT, M29F002BNT 2 Mbit (256Kb x8, Boot Block) Single Supply Flash Memory provides a single 5V ± 10% supply voltage for program, erase, and read operations, with 45 ns access time, 8 µs byte programming time, and 7 memory blocks. The memory includes 1 boot block (top or bottom location), 2 parameter blocks, and 4 main blocks. The device features embedded byte program algorithm, embedded multi-block/chip erase algorithm, status register polling and toggle bits, erase suspend and resume modes, read and program another block during erase suspend mode, unlock bypass program command, faster production/batch programming, temporary block unprotection mode, low power consumption (standby and automatic standby), 100,000 program/erase cycles/block, and 20 years data retention (defectivity below 1 ppm/year). Electronic signature includes manufacturer code (20h), top device code M29F002BT (B0h), top device code M29F002BNT (B0h), bottom device code M29F002BB (34h), and bottom device code M29F002BNB (34h).
The M29F002 series provides 2 Mbit (256 Kb × 8) single‑supply flash memory with a boot block, parameter blocks and main blocks. The devices operate from a 5 V supply and support read, program and erase operations, with built‑in block protection and an on‑chip program/erase controller.
The handbook describes absolute maximum ratings, signal definitions, bus operations, command sequences, and timing characteristics. It also lists package options (TSOP32, PLCC32, PDIP32) and provides electrical specifications such as voltage ranges, temperature limits, program/erase cycles and data retention.
