Atmel AT49BV320D(T) Flash Memory Datasheet
The AT49BV320D(T) is a 32‑megabit flash memory device offered in TSOP and CBGA packages. It supports single‑voltage read/write operation from 2.65 V to 3.6 V, provides 71 erase sectors, and includes flexible sector protection with soft‑lock, hard‑lock and a WP pin. The device features low‑power operation (10 mA active, 15 pA standby) and a 128‑bit protection register for security.
The datasheet details command sequences for read, program, erase, suspend/resume, and status register handling. It also describes the VPP pin behavior, sector‑locking states, and provides revision history and contact information for Atmel worldwide offices.
