LC66PG5XX中文资料三洋数据手册PDF规格书

Overview

The LC66PG5XX is an EPROM-mountable type 4-bit microcomputer for developing and evaluating programs written for the CMOS 4-bit single-chip LC665XX series microcomputers. 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 incorporating 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 resistors 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 external pin levels

• Instruction cycle time 0.92 to 10 microseconds.

• +5V single power source.
