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
accessed in less than 90 ns. With a typical power dissipation of only 18 mW at 5 MHz

The AT27LV010A is available in industry standard
JEDEC-approved one-time programmable (OTP) plastic

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
gramming Algorithm reduces the time required to program
the part and guarantees reliable programming. Programming time i s typically only 100 µs/byte. The Integrated
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
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
and Ground terminals. This capacitor should be posi-
