AT49BV322D(T) is a 2.7V 32-megabit Flash memory organized as 2,097,152 words of 16 bits each or 4,194,304 bytes of 8 bits each. The x16 data appears on I/O0 - I/O15; the x8 data appears on I/O0 - I/O7. The memory is divided into 71 sectors for erase operations. The device is offered in a 48-lead TSOP and a 48-ball CBGA package. The device has CE and OE control signals to avoid any bus contention. This device can be read or reprogrammed using a single power supply, making it a reliable and compact solution with excellent performance and cost-effectiveness.
The AT49BV322D is a 32‑megabit (2M × 16 / 4M × 8) flash memory that operates from a single 2.65 V to 3.6 V supply. It offers fast programming (10 µs word program) and sector erase (100 ms) with suspend/resume capabilities, low‑power standby (15 pA) and up to 100 000 erase cycles.
The document provides a full pin‑out for the 48‑lead TSOP and 48‑ball CBGA packages, command‑sequence timing, status‑bit operation, sector lockdown, protection register details, and revision history, enabling designers to integrate the device in‑system and to program it safely.
