Description
The AT27C040 chip is a low-power, high-performance, 4,194,304-bit one-time pro-
grammable read only memory (OTP EPROM) organized as 512K by 8 bits. The
AT27C040 requires only one 5V power supply in normal read mode operation. Any
byte can be accessed in less than 70 ns, eliminating the need for speed reducing
WAIT states on high-performance microprocessor systems.
Atmel's scaled CMOS technology provides low active power consumption, and fast
programming. Power consumption is typically 8 mA in active mode and less than 10
µA in standby mode.

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

1. VCC must be applied simultaneously or before VPP and removed simultaneously or after VPP.
2. This parameter is only sampled and is not 100% tested. Output Float is defined as the point where data is no longer driven
— see timing diagram.
3. Program Pulse width tolerance is 100 µsec ± 5%.
