Notes:

1. Typical program and erase times assume the following conditions: 25°C, 5.0V VCC, 100,000 cycles. Additionally,

programming typically assumes checkerboard pattern.

2. Under worst case conditions of 90°C, VCC = 4.5V (4.75V for -55), 100,000 cycles.

3. The typical chip programming time is considerably less than the maximum chip programming time listed, since most bytes

program faster than the maximum byte program time listed. If the maximum byte program time given is exceeded, only

then does the device set I/O5 = 1. See the section on I/O5 for further information.

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 for further information on command definitions.

6. The device has a guaranteed minimum erase and program cycle endurance of 100,000 cycles.
