AT27BV512  
Green (Pb/Halide-free) Packaging Option  
1. Description  
The AT27BV512 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 2.7 to 3.6V in normal read mode operation,  
making it ideal for fast, portable systems using either regulated or unregulated 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 = 2.7V, any byte can be  
accessed in less than 70 ns. With a typical power consumption of only 18 mW at  
5 MHz and VCC = 3V, the AT27BV512 consumes less than one fifth the power of a  
standard 5V EPROM.  
Standby mode supply current is typically less than 1 µA at 3V. The AT27BV512 simpli-  
fies system design and stretches battery lifetime even further by eliminating the need  
for power supply regulation.  
The AT27BV512 is available in industry-standard JEDEC-approved one-time  
programmable (OTP) plastic PLCC, SOIC, and TSOP packages. All devices feature  
two-line control (CE, OE) to give designers the flexibility to prevent bus contention.  
The AT27BV512 operating with VCC at 3.0V produces TTL level outputs that are com-  
patible with standard TTL logic devices operating at VCC = 5.0V. At VCC = 2.7V, the  
part is compatible with JEDEC approved low voltage battery operation (LVBO) inter-  
face specifications. 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.
