AC CHARACTERISTICS
ERASE AND PROGRAMMING PERFORMANCE
Notes:
1. Typical program and erase times assume the following conditions: 25×C, 5.0 V VCC, 100,000 cycles. Additionally,
2. Under worst case conditions of 90°C, VCC = 4.5 V (4.75 V for -45), 100,000 cycles.
3. The typical chip programming time is considerably less than the maximum chip programming time listed, since most bytes
4. In the pre-programming step of the Embedded Erase algorithm, all bytes are programmed to 00h before erasure.
5. System-level overhead is the time required to execute the four-bus-cycle command sequence for programming. See Table 4
6. The device has a minimum erase and program cycle endurance 100,000 cycles guaranteed.
