Description
The AT27BV010 is a high performance, low power, low voltage 1,048,576 bit one-
time programmable read only memory (OTP EPROM) organized as 128K by 8 bits.
It requires only one supply in the range of 2.7V to 3.6V in normal read mode opera-
tion, 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

accessed in less than 70 ns. With a typical power draw of only 18 mW at 5 MHz and
V
= 3V, the AT27BV010 consumes less than one fifth the power of a standard 5V

System Considerations
EPROM. Standby mode supply current is typically less
than 1 µA at 3V. The AT27BV010 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

tioned as close as possible to the point where the power
supply is connected to the array.
Atmel’s AT27BV010 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 AT27BV010
programs exactly the same way as a standard 5V
AT27C010 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.

Notes: 1. The Input Timing Reference is 0.8V for VIL and
2.0V for VIH.
3. When programming the AT27BV010, a 0.1 µF capacitor is
required across VPP and ground to suppress spurious
voltage transients.
2. tOE and tDFP are characteristics of the device but
must be accommodated by the programmer.

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-
lected until all have been checked. V is then lowered to
5.0V and V to 5.0V. All bytes are read again and com-
pared with the original data to determine if the device
passes or fails.
