Note:

1. The AT27LV010A has the same Product Identification

Code as the AT27C010. Both are programming

compatible.

*AC Conditions of Test:

Input Rise and Fall Times (10% to 90%)..........20 ns

Input Pulse Levels................................0.45V to 2.4V

Input Timing Reference Level................0.8V to 2.0V

Output Timing Reference Level.............0.8V to 2.0V

2. This parameter is only sampled and is not 100%

tested. Output Float is defined as the point where

data is no longer driven —see timing diagram.

3. Program Pulse width tolerance is 100

Rapid Programming Algorithm

A 100

µs PGM pulse width is used to program. The ad-

with one 100

µs PGM pulse without verification. Then a

verification / reprogramming loop is executed for each ad-

dress. In the event a byte fails to pass verification, up to

10 successive 100

µs pulses are applied with a verifica-

tion after each pulse. If the byte fails to verify after 10

pulses have been applied, the part is considered failed.

After the byte verifies properly, the next address is se-

pared with the original data to determine if the device

passes or fails.
