PD75P116
Function
Voltage application pin for program memory write/verify
(normally VDD potential).
Address update clock inputs for program memory write/
verify. Inverse of X1 pin signal is input to X2 pin.
Operating mode selection pin for program memory write/
verify.
8-bit data input/output pins for progrm memory write/
verify.
Supply voltage application pin.
Applies 5 V
± 10 % in normal operation, and 6 V for
program memory write/verify.

Note
Since the
PD75P116 is a one-time PROM version, UV-ray erasure is not possible.
3.1
PROGRAM MEMORY WRITE/VERIFY OPERATING MODES
The
PD75P116 assumes the program memory write/verify mode is +6 V and +12.5 V are applied respec-
tively to the VDD and VPP pins. The table below shows the operating modes available by the MD0 to MD3 pin
setting in this mode. The rest of pins are all set at the VSS potential by the pull-down resistor.

PROM (PROGRAM MEMORY) WRITE AND VERIFY
The ROM built into the
PD75P116 is a 16256 × 8-bit PROM. The pins shown in the table below are used to
write/verify this PROM. There is no address input; instead, a method to update the address by the clock input
from the X1 pin is adopted.
