ERASE AND PROGRAMMING PERFORMANCE
Notes:
1. The typical erase and programming times assume the following conditions: 25
°
C, 5.0 volt V
CC
, 100,000 cycles. These
conditions do not apply to erase/program endurance. Programming typicals assume checkerboard pattern.
2. The maximum erase and programming times assume the following conditions: 90
°
C, 4.5 volt V
CC
, 100,000 cycles.
3. Although Embedded Algorithms allow for longer chip program and erase time, the actual time will be considerably less since
bytes program or erase significantly faster than the worst case byte.
4. System-level overhead is defined as the time required to execute the four bus cycle command necessary to program each
byte. In the preprogramming step of the Embedded Erase algorithm, all bytes are programmed to 00H before erasure.
5. The Embedded Algorithms allow for 2.5 ms byte program time. DQ5 = “1” only after a byte takes the theoretical maximum
time to program. A minimal number of bytes may require significantly more programming pulses than the typical byte. The
majority of the bytes will program within one or two pulses. This is demonstrated by the Typical and Maximum Programming
Times listed above.
