3/5#
INPUT
3.3/5.0 VOLT SELECT:
3/5# high configures internal circuits for 3.3V
operation. 3/5# low configures internal circuits for 5.0V operation.
NOTE:
Reading the array with 3/5# high in a 5.0V system could damage the
device. Reference the power-up and reset timings (Section 5.9) for 3/5#
switching delay to valid data.
PROGRAM/ERASE POWER SUPPLY (12.0V ± 0.6V, 5.0V ± 0.5V):
For
erasing memory array blocks or writing words into the flash array. V
PP
=
5.0V ± 0.5V eliminates the need for a 12.0V converter, while connection
to 12.0V ± 0.6V maximizes program/erase performance.
NOTE:
Successful completion of program and erase attempts is inhibited with
V
PP
at or below 1.5V. Program and erase attempts with V
PP
between 1.5V
and 4.5V, between 5.5V and 11.4V, and above 12.6V produce spurious
results and should not be attempted.
DEVICE POWER SUPPLY (3.3V ± 0.3V, 5.0V ± 0.5V):
To switch 3.3V to 5.0V (or vice versa), first ramp V
CC
down to GND, and
then power to the new V
CC
voltage.
Do not leave any power pins floating.
GROUND FOR ALL INTERNAL CIRCUITRY:
Do not leave any ground pins floating.
NO CONNECT:
Lead may be driven or left floating.
