ES29LV320D is a 32Mbit (4M x 8/2M x 16) CMOS 3.0 Volt-only, Boot Sector Flash Memory manufactured by Excel Semiconductor. It features single power supply operation, sector structure, top or bottom boot block, and an extra security code sector.
The ES29LV320D is a 32‑Mbit CMOS flash memory device that operates at a single 3.0 V power supply (2.7 V‑3.6 V range). It is offered in a 48‑pin TSOP package and is RoHS‑compliant. The device supports both byte (4M × 8) and word (2M × 16) configurations, with eight boot sectors and sixty‑three main sectors, plus a 256‑byte security sector.
Key features include fast access times (80 ns‑120 ns), low standby current (200 nA), and robust endurance (minimum 100 000 program/erase cycles per sector with 20‑year data retention at 125 °C). The datasheet details hardware pins, bus operations, power‑down modes, programming algorithms, and sector protection mechanisms.
