Erase and Programming Performance
Notes:
1. Typical program and erase times assume the following conditions: 25
°C, 1.8 V VCC, 1 million cycles. Additionally,
programming typicals assumes a checkerboard pattern.
2. Under worst case conditions of 90°C, VCC = 1.65 V, 1,000,000 cycles.
3. The typical chip programming time is considerably less than the maximum chip programming time listed.
4. In the pre-programming step of the Embedded Erase algorithm, all words 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 million cycles.
FBGA Ball Capacitance
Notes:
1. Sampled, not 100% tested.
2. Test conditions TA = 25°C, f = 1.0 MHz.
3. Fortified BGA ball capacitance TBD.
