Description
The AT27LV040A is a high performance, low power, low voltage, 4,194,304 bit one-
time programmable read only memory (OTP EPROM) organized as 512K by 8 bits.
It requires only one supply in the range of 3.0 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 3V supply. At VCC = 3.0V, any byte can be
accessed in less than 120 ns. With a typical power dissipation of only 18 mW at 5
MHz and VCC = 3.3V, the AT27LV040A consumes less than one half the power of a
standard 5V EPROM. Standby mode supply current is typically less than 1 µA at
3.3V.

Description (Continued)
The AT27LV040A 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.
The AT27LV040A operating with VCC 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 AT27LV040A 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 AT27LV040A
programs exactly the same way as a standard 5V
AT27C040 and uses the same programming equipment.
System Considerations
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
be connected between the VCC 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 posi-
tioned as close as possible to the point where the power
supply is connected to the array.
