AT27LV040A  
1. 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 90 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 stan-  
dard 5V EPROM. Standby mode supply current is typically less than 1 µA at 3.3V.  
The AT27LV040A is available in industry-standard JEDEC-approved one-time pro-  
grammable (OTP) plastic PLCC, TSOP, and VSOP 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 pro-  
duction 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 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.
