AC Programming Characteristics
T
A
= 25 ± 5°C, V
CC
= 6.5 ± 0.25V, V
PP
= 13.0 ± 0.25V
*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
Notes:
1. V
CC
must be applied simultaneously or before V
PP
and removed simultaneously or after V
PP
.
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
μ
sec
±
5%.

Note:
1. The AT27LV020A has the same Product Identification
Code as the AT27C020. Both are programming com-
patible.
Rapid
Programming Algorithm
A 100
μ
s PGM pulse width is used to program. The
address is set to the first location. V
CC
is raised to 6.5V and
V
PP
is raised to 13.0V. Each address is first programmed
with one 100
μ
s PGM pulse without verification. Then a
verification/reprogramming loop is executed for each
address. In the event a byte fails to pass verification, up to
10 successive 100
μ
s pulses are applied with a verification
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 selected until all
have been checked. V
PP
is then lowered to 5.0V and V
CC
to 5.0V. All bytes are read again and compared with the
original data to determine if the device passes or fails.
