| Capacity | 64-megabit (4M x 16) |
|---|---|
| Supply Voltage | 2.65V - 3.6V |
| Access Time | 70 ns |
| Sector Erase Time (32K) | 500 ms |
The device supports single-voltage operation between 2.65V and 3.6V, or a narrower range of 2.7V to 3.6V.
Typical sector erase time for 32K Word Sectors is 500 ms.
A low level on the RESET pin halts operation and puts the outputs in a high-impedance state.
