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 V = 2.7V, any byte can be
CC
accessed in less than 90 ns. With a typical power consumption of only 18 mW at 5
MHz and V
= 3V, the AT27BV512 consumes less than one fifth the power of a
CC
standard 5V EPROM.

System Considerations
Description (Continued)
Standby mode supply current is typically less than 1 µA at
3V. The AT27BV512 simplifies system design and
stretches battery lifetime even further by eliminating the
need for power supply regulation.
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
The AT27BV512 is available in industry standard JEDEC-
approved one-time programmable (OTP) plastic PLCC,
SOIC, and TSOP packages. All devices feature two-line
control (CE, OE) to give designers the flexibility to prevent
bus contention.

to stabilize the supply voltage level on printed circuit
boards with large EPROM arrays, a 4.7 µF bulk electrolytic
capacitor should be utilized, again connected between the

tioned as close as possible to the point where the power
supply is connected to the array.
Atmel’s AT27BV512 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/byte. 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 AT27BV512
programs exactly the same way as a standard 5V
AT27C512R 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 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.
4. VH = 12.0 ± 0.5V.
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 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.
