Evaluation Chip for The LC665XX Series
Microcomputers
Overview
The LC66PG5XX is an EPROM-mountable type 4-bit mi-
crocomputer for developing and evaluating programs writ-
ten for the CMOS 4-bit single-chip LC665XX series mi-
crocomputers. Either 2764 or 27128 type EPROM can be
mounted on the LC66PG5XX. The LC66PG5XX with the
EPROM mounted can carry out the same functions as those
of the LC665XX series microcomputers. Therefore, you
can evaluate programs developed for application products
controlled by the LC665XX series microcomputers by in-
corporating the LC66PG5XX into the applications before
the programs are masked in the ROMs.

Features
• Either 2764 or 27128 type EPROM can be mounted.
• Shrink type 64-pin configuration compatible with the
LC665XX series microcomputers. Note that pull-up re-
sistors need to be externally added.
• Options provided for selecting functions.
Options allowing the user to select output signal level for
ports 0, 1 and 8 at the initial reset or to specify whether
the watchdog timer function is employed by setting ex-
ternal pin levels
• Instruction cycle time 0.92 to 10 microseconds.
• +5V single power source.
The LC66PG5XX has the 28-pin soket and 14-pin soket
on the top face of the package. It also has the shrink type
64-pin terminals on the bottom face of the package. The
28-pin soket is used for mounting the EPROM containing
the programs and 14-pin soket for selecting functions by
options (input/output options not included). The shrink type
64-pin terminals are compatible with the LC665XX series
microcomputers.
