AT49SV322D(T) is a 1.8-volt 32-megabit Flash memory with features including single voltage read/write operation, 80 ns access time, 63 32K word (64K Bytes) sectors and 8 4K word (8K Bytes) sectors with individual write lockout, fast word program time, low-power operation, etc.
The AT49BV322DT is a 1.8‑volt 32‑megabit flash memory organized as 2,097,152 words of 16 bits. It offers 71 erase sectors (63 × 32 K‑word and 8 × 4 K‑word) and supports single‑voltage read/write operation, low‑power active and standby modes, and a 128‑bit protection register.
The document describes command sequences for read, program, erase, suspend/resume, sector lockdown, and status detection via READY/BUSY, data polling, and toggle‑bit methods. It also details package options (48‑lead TSOP and 48‑ball CBGA) and the Common Flash Interface (CFI) query mode.
| Operating voltage | 1.65‑1.95 V |
|---|---|
| Access time | 80 ns |
| Fast word program time | 10 µs |
| Fast sector erase time | 100 ms |
| Active current | 10 mA |
| Minimum erase cycles | 100 000 |
| Memory size | 32 megabit (2 M × 16) |

The device operates from 1.65 V to 1.95 V.
The flash memory is guaranteed for a minimum of 100 000 erase cycles.
Issue the six‑bus‑cycle Sector Lockdown command; the sector then becomes read‑only until a reset or power‑up.
The VPP pin provides write protection and accelerated program operation.
