Description
The AT27BV020 is a high-performance, low-power, low-voltage 2,097,152-bit one-
time programmable read only memory (OTP EPROM) organized as 256K 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.

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, expect during programming. 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 AT27BV020 a 0.1 µF capacitor is required across VPP and ground to suppress spurious voltage
transients.
