ERASE AND PROGRAMMING PERFORMANCE

Notes:

1. 25

°C, 5 V V

2. Under worst case condition of 90

°C, 4.5 V V

3. 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.

4. The Embedded Algorithms allow for 1.8 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 (7 to 14

µs).This is demonstrated by the Typical and Maximum Programming

Times listed above.
