20. Erase and Programming Performance
Notes
1. Typical program and erase times assume the following conditions: 25
°
C, 1.8 V V
CC
, 10,000 cycles typical. Additionally, programming
typicals assume checkerboard pattern.
2. Under worst case conditions of 90°C, V
CC
= 1.70 V, 100,000 cycles.
3. Effective write buffer specification is based upon a 32-word write buffer operation.
4. The typical chip programming time is considerably less than the maximum chip programming time listed, since most words program faster
than the maximum program times listed.
5. In the pre-programming step of the Embedded Erase algorithm, all words are programmed to 00h before erasure.
6. System-level overhead is the time required to execute the two- or four-bus-cycle sequence for the program command. See
Table 11.4 on
page 52
for further information on command definitions.
21. BGA Ball Capacitance
Notes
1. Sampled, not 100% tested.
2. Test conditions T
A
= 25°C, f = 1.0 MHz.
