256K (32K x 8) Unregulated Battery-Voltage™ High Speed OTP CMOS EPROM

Atmel Corporation 

Programming Waveforms (1)

AT27BV256

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 AT27BV256 a 0.1 µF capacitor is

required across VPP and ground to suppress spurious volt-

age transients.
