AT27C256R
6
Programming Waveforms
(1)
Notes: 1. The Input Timing Reference is 0.8V for V
IL
and 2.0V for V
IH
.
2. t
OE
and t
DFP
are characteristics of the device but must be accommodated by the programmer.
3. When programming the AT27C256R a 0.1
µ
F capacitor is required across V
PP
and ground to suppress spurious voltage
transients.
