(Rev.:2001)

2-Megabit (256K x 8) Unregulated Battery-Voltage High Speed OTP EPROM

Atmel Corporation 

Programming Waveforms(1)

AT27BV020

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.
