µPD75112(Aw)w,w.D7at5aS1he1et46U.c(oAm )
4-Bit Single Chip-Microcomputer
Description
The µPD75116(A) is one of the 4-bit single-chip micro-
computer 75X series.
The µPD75116(A) is a product with the extended ROM
capacity of the µPD75108(A). In addition of high-speed
operations, it can manipulate data in units of 1, 4 and 8
bits. In particular, the I/O operation of the µPD75116
have been improved by a wide variety of bit control
instructions. The µPD75116 is provided with interface
inputs/outputs with peripheral circuits having different
power voltages, and analog inputs and suitable for
controlling automobile electrical equipment, etc. For
the µPD75116(A), an on-chip pin-compatible one-time
PROM product (µPD75P116) is separately available for
system development evaluation.
Functions are described in detail in the following User’s
Manual, which should be read when carrying out
design work.

5.3 Clock Output Circuit
The clock output circuit is a circuit to generate clock
pulses from the P22/PCL pin. It is used to supply the
peripheral LSIs with clock pulses.
Clock output (PCL):Φ, 524 kHz, 262 kHz (at 4.19 MHz
operation)
The clock output cicuit configuration is shown as the
following.
