1. Description  
The AT27BV1024 is a high-performance, low-power, low-voltage 1,048,576-bit one-  
time programmable read-only memory (OTP EPROM) organized as 64K by 16 bits. It  
requires only one supply in the range of 2.7V to 3.6V in normal read mode operation.  
The by-16 organization makes this part ideal for portable and handheld 16- and 32-bit  
microprocessor based systems using either regulated or unregulated battery power.  
AT27BV1024  
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 word can be  
accessed in less than 120 ns. With a typical power dissipation of only 18 mW at 5 MHz  
and VCC = 3V, the AT27BV1024 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 AT27BV1024 sim-  
plifies system design and stretches battery lifetime even further by eliminating the  
need for power supply regulation.  
The AT27BV1024 is available in industry standard JEDEC-approved one-time pro-  
grammable (OTP) plastic PLCC and VSOP packages. All devices feature two-line  
control (CE, OE) to give designers the flexibility to prevent bus contention.  
The AT27BV1024 operating with VCC at 3.0V produces TTL level outputs that are  
compatible 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)  
interface specifications. The device is also capable of standard 5-volt operation mak-  
ing it ideally suited for dual supply range systems or card products that are pluggable  
in both 3-volt and 5-volt hosts.  
Atmel’s AT27BV1024 has additional features to ensure high quality and efficient  
production use. The Rapid Programming Algorithm reduces the time required to pro-  
gram the part and guarantees reliable programming. Programming time is typically  
only 100 µs/word. The Integrated Product Identification Code electronically identifies  
0631E–EPROM–12/07
