The document describes the features and characteristics of the AT29LV020 product, including single voltage supply, 3V to 3.6V supply range, fast read access time, low power dissipation, etc.
The AT29LV020 is a 3‑volt‑only, in‑system flash programmable read‑only memory offering 2 Mbit (256 K × 8) of storage organized into 1024 sectors of 256 bytes each. It features fast 100 ns read access, low active current (15 mA) and ultra‑low standby current (50 pA), and provides optional 8 KB boot blocks with programmable lockout.
The datasheet includes pin configurations for 32‑lead PLCC and TSOP packages, detailed timing diagrams, operating modes, absolute maximum ratings, and packaging dimensions. Electrical characteristics such as input/output voltage levels, current consumption, and timing parameters are specified for reliable integration into embedded systems.
