Description
The AT27C020 is a low-power, high performance 2,097,152-bit one-time programma-
ble read only memory (OTP EPROM) organized as 256K by 8 bits. It requires only
one 5V power supply in normal read mode operation. Any byte can be accessed in
less than 55 ns, eliminating the need for speed reducing WAIT states on high perfor-
mance microprocessor systems.
In read mode, the AT27C020 typically consumes 8 mA. Standby mode supply current
is typically less than 10 µA.

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.
