Description

The AT27LV040A is a high performance, low power, low voltage, 4,194,304 bit one­time 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 V
accessed in less than 120 ns. With a typical power dissipation of only 18 mW at 5
MHz and V
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 (
bus contention.

The AT27LV040A operating with V
TTL level outputs that are compatible with standard TTL
logic devices operating at V
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
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 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 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-

Rapid Programming Algor ithm

A 100 µs CE pulse width is used to program. The address
is set to the first location. V
raised to 13.0V. Each address is first programmed with
one 100 µs

CE 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. V

is then lowered to 5.0V and VCC to

original data to determine if the device passes or fails.
