FLASH ERASE AND PROGRAMMING PERFORMANCE
Notes:
1. Typical program and erase times assume the following conditions: 25
°C, 2.0 V V
CC, 1,000,000 cycles. Additionally,
programming typicals assume checkerboard pattern.
2. Under worst case conditions of 90
°C, V
CC = 1.8 V,
1,000,000 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 program times
listed.
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
two- or four-bus-cycle sequence for the program command.
See Table 13 for further information on command
definitions.
6. The device has a minimum erase and program cycle endurance of 1,000,000 cycles.
FLASH LATCHUP CHARACTERISTICS
