AC CHARACTERISTICS

Write/Erase/Program Operations

Notes:

1. Rise/Fall ð 10 ns.

2. Maximum specification not needed due to the devices internal stop timer that will stop any erase or write operation that exceed

the device specification.

3. Embedded Program Operation of 16

µs consist of 10 µs program pulse and 6 µs write recovery before read. This is the

minimum time for one pass through the programming algorithm. D5 = “1” only after a byte takes longer than 48 ms to Write.
