Notes:
1. Typical program and erase times assume the following conditions: 25°C, 3.0 V VCC, Programming specification assume that
all bits are programmed to 00h.
2. Maximum values are measured at VCC = 3.0, worst case temperature. Maximum values are valid up to and including 100,000
program/erase cycles.
3. Word/Byte programming specification is based upon a single word/byte programming operation not utilizing the write buffer.
4. For 1-16 words or 1-32 bytes programmed in a single write buffer programming operation.
5. Effective write buffer specification is calculated on a per-word/per-byte basis for a 16-word/32-byte write buffer operation.
6. In the pre-programming step of the Embedded Erase algorithm, all bits are programmed to 00h before erasure.
7. System-level overhead is the time required to execute the command sequence (s) for the program command. See Tables 12 and
13 for further information on command definitions.
8. The device has a minimum erase and program cycle endurance of 100,000 cycles.
