Notes:
1. Typical program and erase times assume the following conditions: 25°C, 5.0 V VCC, 1 million cycles. Additionally,
programming typicals assume checkerboard pattern.
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
program faster than the maximum byte program time listed. If the maximum byte program time given is exceeded, only then
does the device set DQ5 = 1. See the section on DQ5 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 minimum guaranteed erase cycle endurance of 1 million cycles.
