AC CHARACTERISTICS - Write Operations
NOTES:
1. Read timing characteristics during erase and byte write operations are the same as during read-only operations. Refer to AC
2. Sampled, not 100% tested.
3. Refer to Table 3 for valid A
4. Refer to Table 3 for valid D
5. The on-chip Write State Machine incorporates all byte write and block erase system functions and overhead of standard SHARP
6. Byte write and block erase durations are measure to completion (SR.7=1, RY/ BY#=V
7. See High Speed AC Input/Output Reference Waveforms and High Speed AC Testing Load Circuits for testing characteristics.
8. See AC Input/Output Reference Waveforms and AC Testing Load Circuits for testing characteristics.
