ATMEL AT49BV001A/AT49BV001AN/AT49BV001AT/AT49BV001ANT handbook
The AT49BV001A is a 1‑megabit, in‑system reprogrammable flash memory offered by Atmel. It operates from a single 2.7 V to 3.6 V supply and provides a fast 55 ns read access time. The device is organized into a 16 KB boot block, two 8 KB parameter blocks and two main memory blocks of 32 KB and 64 KB.
The datasheet describes the pin configurations for VSOP and TSOP packages, the command sequences for read, program, erase and lockout operations, and the electrical characteristics such as active current (15 mA), standby current (50 pA), and operating temperature ranges. It also details the boot block programming lockout feature and how it can be overridden with a 12 V reset pulse.
