Pin Functions in PROM Mode
V_PP:
Applies the on-chip PROM programming voltage (12.5 V ±0.3 V).
CE:
Inputs a control signal to set the on-chip PROM to the write/verify enabled state.
OE:
Inputs a data output control signal during verification.
A₀ to A₁₄:
On-chip PROM address input pins.
O₀ to O₄:
On-chip PROM data bus I/O pins.
MO, RESET, TEST:
PROM mode setting pins. PROM mode is set by driving the RESET, and MO pins low, and driving the
TEST pin to the V_PP level.
Other pins:
V_CC and AV_CC should be connected to V_CC potential.
GND, AV_SS, and X1 should be connected to GND potential.
Other pins should be left open.
