Description
The AT27LV010A 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 3.0V to 3.6V in normal read mode opera-
tion, making it ideal for fast, portable systems using battery power.
Atmel’s innovative design techniques provide fast speeds that rival 5V parts while
keeping the low power consumption of a 3.3V supply. At V = 3.0V, any byte can be
CC
accessed in less than 90 ns. With a typical power dissipation of only 18 mW at 5 MHz
and V = 3.3V, the AT27LV010A consumes less than one fifth the power of a stand-
CC
ard 5V EPROM. Standby mode supply current is typically less than 1 µA at 3.3V.

System Considerations
The AT27LV010A is available in industry standard
JEDEC-approved one-time programmable (OTP) plastic
PLCC and TSOP packages. All devices feature two-line
control (CE, OE) to give designers the flexibility to prevent
bus contention.
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 device, as close to the device as possible. Additionally,
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
capable of standard 5-volt operation making it ideally
suited for dual supply range systems or card products that
are pluggable in both 3-volt and 5-volt hosts.
Atmel’s AT27LV010A 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 AT27LV010A
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 output
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 +7.0
volts for pulses of less than 20 ns.

3. When programming the AT27LV010A a 0.1 µF capacitor
is required across VPP and ground to suppress spurious
