Description
The AT27LV512A is a high performance, low power, low voltage 524,288 bit one-time programmable read only memory (OTP EPROM) organized as 64K 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 and V ard 5V EPROM.

Description (Continued)
Standby mode supply current is typically less than 1 µA at
3.3V. The AT27LV512A is available in industry standard
JEDEC-approved one-time programmable (OTP) plastic PLCC, SOIC, and TSOP packages. All devices feature two-line control ( prevent bus contention.
The AT27LV512A 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 AT27LV512A 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 AT27LV512A programs exactly the same way as a standard 5V AT27C512R 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 OE/VPP is raised to 13.0V. Each address is first pro­grammed with one 100 µs 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 ve rifies properly, the next address is se­lected until all have been checked. ered to V
