Description
The AT27BV512 is a high performance, low power, low voltage 524,288 bit one-time
programmable read only memory (OTP EPROM) organized as 64K by 8 bits. It re-
quires only one supply in the range of 2.7V to 3.6V in normal read mode operation,
making it ideal for fast, portable systems using either regulated or unregulated battery
power.
Atmel’s innovative design techniques provide fast speeds that rival 5V parts while
keeping the low power consumption of a 3V supply. At VCC = 2.7V, any byte can be
accessed in less than 90 ns. With a typical power consumption of only 18 mW at 5
MHz and VCC = 3V, the AT27BV512 consumes less than one fifth the power of a
standard 5V EPROM.

*NOTICE: Stresses beyond those listed under “Absolute Maxi-
mum Ratings” may cause permanent damage to the device.
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 out-
put pin voltage is VCC + 0.75V dc which may be ex-
ceeded if certain precautions are observed (consult
application notes) and which may overshoot to
+7.0V for pulses of less than 20 ns.

Notes: 1. X can be VIL or VIH.
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.
4. VH = 12.0 ± 0.5V.
5. Two identifier bytes may be selected. All Ai inputs are held
low (VIL), except A9 which is set to VH and A0 which is tog-
gled low (VIL) to select the Manufacturer’s Identification byte
and high (VIH) to select the Device Code byte.
