Description
The AT27BV4096 is a high performance, low power, low voltage 4,194,304 bit one-
time programmable read only memory (OTP EPROM) organized as 256K by 16 bits.
It requires only one supply in the range of 2.7V to 3.6V in normal read mode opera-
tion. The by-16 organization makes this part ideal for portable and handheld 16 and
32 bit microprocessor based systems using either regulated or unregulated battery
power.

System Considerations
Switching between active and standby conditions via the
Chip Enable pin may produce transient voltage excur-
sions. Unless accommodated by the system design, these
transients may exceed data sheet limits, resulting in de-
vice non-conformance. At a minimum, a 0.1 µF high fre-
quency, low inherent inductance, ceramic capacitor
should be utilized for each device. This capacitor should

to stabilize the supply voltage level on printed circuit

logic devices operating at V = 5.0V. At V = 2.7V, the

part is compatible with JEDEC approved low voltage bat-
tery operation (LVBO) interface specifications. The device
is also capable of standard 5-volt operation making it ide-
ally suited for dual supply range systems or card products
that are pluggable in both 3-volt and 5-volt hosts.
Atmel’s AT27BV4096 has additional features to ensure
high quality and efficient production use. The Rapid Pro-
gramming Algorithm reduces the time required to program
the part and guarantees reliable programming. Program-
ming time is typically only 100 µs/word. The Integrated
Product Identification Code electronically identifies the de-
vice and manufacturer. This feature is used by industry
standard programming equipment to select the proper
programming algorithms and voltages. The AT27BV4096
programs exactly the same way as a standard 5V
AT27C4096 and uses the same programming equipment.

*NOTICE: Stresses beyond those listed under “Absolute Maxi-

This is a stress rating only and functional operation of the
device at these or any other conditions beyond those indi-
cated in the operational sections of this specification is not
implied. Exposure to absolute maximum rating conditions
for extended periods may affect device reliability.
Note: 1. Minimum voltage is -0.6V dc which may undershoot to
-2.0V for pulses of less than 20 ns. Maximum output
pin voltage is VCC + 0.75V dc which may overshoot
to +7.0V for pulses of less than 20 ns.

2. Read, output disable, and standby modes require,
2.7V ≤ VCC ≤ 3.6V, or 4.5V ≤ VCC ≤ 5.5V.
3. Refer to Programming Characteristics. Programming
modes require VCC = 6.5V.
5. Two identifier words may be selected. All Ai inputs
are held low (VIL), except A9 which is set to VH and A0
which is toggled low (VIL) to select the Manufacturer’s Identi-

one 50 µs CE pulse without verification. Then a verifica-

In the event a word fails to pass verification, up to 10 suc-
cessive 50 µs pulses are applied with a verification after
each pulse. If the word fails to verify after 10 pulses have
been applied, the part is considered failed. After the word
