1. Description  
The AT27LV020A is a high-performance, low-power, low-voltage 2,097,152 bit one-  
time programmable read-only memory (OTP EPROM) organized as 256K 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 AT27LV020A consumes less than one fifth the power of a stan-  
dard 5V EPROM. Standby mode supply current is typically less than 1 µA at 3.3V.  
The AT27LV020A is available in industry-standard JEDEC approved one-time pro-  
grammable (OTP) plastic PLCC, TSOP, and VSOP. All devices feature two-line  
control (CE, OE) to give designers the flexibility to prevent bus contention.  
The AT27LV020A 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 AT27LV020A 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  
AT27LV020A programs exactly the same way as a standard 5V AT27C020 and uses  
the same programming equipment.
