Description
The AT27BV040 chip is a high performance, low power, low voltage, 4,194,304 bit
one-time programmable read only memory (EPROM) organized as 512K 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 100 ns. With a typical power dissipation of only 18 mW at 5
MHz and VCC = 3V, the AT27BV040 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 AT27BV040 simplifies system design and stretches battery lifetime even further
by eliminating the need for power supply regulation.

Notes: 1. VCC must be applied simultaneously with or before
VPP, and removed simultaneously with or after VPP.
2. VPP may be connected directly to VCC, except during pro-
gramming. The supply current would then be the sum of ICC
and IPP.

Notes: 1. The Input Timing Reference is 0.8V for VIL and
2.0V for VIH.
2. tOE and tDFP are characteristics of the device but
must be accommodated by the programmer.
3. When programming the AT27BV040 a 0.1 µF capacitor
is required across VPP and ground to suppress spuri-
ous voltage transients.
