Description
The AT27LV010A is a high performance, low power, low voltage 1,048,576-bit onetime 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 operation,
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 CC = 3.0V, any byte can be
accessed in less than 70 ns. With a typical power dissipation of only 18 mW at 5 MHz and V C C = 3.3V, the
AT27LV010A consumes less than one fifth the power of a
standard 5V EPROM. Standby mode supply current is typically less than 1 µA at 3.3V.
The AT27LV010A is available in industry standard JEDECapproved 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.
The AT27LV010A operating with V CC at 3.0V produces TTL
level outputs that are compatible with standard TTL logic
devices operating at VCC = 5.0V. The device is also 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™ Programming Algorithm reduces the time required to program
the part and guarantees reliable programming. Programming time is typically only 100 µs/byte. The Integrated
Block Diagram

AT27LV010A
Product Identification Code electronically identifies the
device 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.
System Considerations
Switching between active and standby conditions via the
Chip Enable pin may produce transient voltage excursions.
Unless accommodated by the system design, these transients may exceed data sheet limits, resulting in device
non-conformance. At a minimum, a 0.1 µF high frequency,
low inherent inductance, ceramic capacitor should be utilized for each device. This capacitor should be connected
between the V CC and Ground terminals of 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 VCC and Ground
terminals. This capacitor should be positioned as close as
possible to the point where the power supply is connected
to the array.

Rapid Programming Algorithm
A 100 µs PGM pulse width is used to program. The
address is set to the first location. VCC is raised to 6.5V and
VPP is raised to 13.0V. Each address is first programmed
with one 100 µs PGM pulse without verification. Then a
verification / reprogramming loop is executed for each
address. In the event a byte fails to pass verification, up to
10 successive 100 µs pulses are applied with a verification
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 selected until all
have been checked. VPP is then lowered to 5.0V and VCC to
5.0V. All bytes are read again and compared with the original data to determine if the device passes or fails.
