Flashrite Programming Algorithm
Notes:
1. See AC and DC Characteristics for values of V
PP
parameters. The V
PP
power supply can be hard-wired to the device or
switchable. When V
PP
is switched, V
PPL
may be ground, no connect with a resistor tied to ground, or less than V
CC
+ 2.0 V
2. Program Verify is performed only after byte programming. A final read/compare may be performed (optional) after the register
is written with the read command.
