AC Characteristics for WE
- Controlled Command Write Operations

CC
= 5.0 V ± 0.5 V, T
A
= 0°C to +70°C
NOTES:
1. Read timing during write and erase are the same as for normal read.
2. Refer to command definition tables for valid address and data values.
3. Sampled, but not 100% tested.
4. Write/Erase durations are measured to valid Status Register (CSR) Data.
5. Byte write operations are typically performed with 1 Programming Pulse.
6. Address and Data are latched on the rising edge of WE
for all Command Write operations.
