AT27BV512

Programming Waveforms

(1)

Notes: 1. The Input Timing Reference is 0.8V for V

and 2.0V for V

2. t

and t

DFP

are characteristics of the device but must be accommodated by the programmer.

3. When programming the AT27BV512, a 0.1

F capacitor is required across V

and ground to suppress spurious voltage

transients.
