ERASE AND PROGRAMMING PERFORMANCE
Notes:
1. Typical program and erase times assume the following conditions: 25
°
C, 3.0 V V
CC
. Programming specifications 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 based upon 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 two- or four-bus-cycle sequence for the program command. See
Table
11
for further information on command definitions.
8. The device has a minimum erase and program cycle endurance of 100,000 cycles.
