AC CHARACTERISTICS
Alternate CE# Controlled Erase/Program Operations
Notes:
1. Not 100% tested.
2. Typical program and erase times assume the following conditions: 25 °C, V
3. Excludes system-level overhead, which is the time required to execute the four-bus-cycle sequence for the program
4. Excludes 0x00 programming prior to erasure. In the preprogramming step of the Automatic Erase algorithm, all bytes are
5. The typical chip programming time is considerably less than the maximum chip programming time listed since most bytes
