CMOS IC
LC86E5632
8-Bit Single Chip Microcontroller
with the One-Time Programmable UVEPROM
Preliminary
Overview
The LC86E5632 is a CMOS 8-bit single chip microcontroller with one-time UVEPROM for the LC865600 series.
This microcontroller has the function and the pin description of the LC865600 series mask ROM version, and 32K-byte
EPROM. The program data is rewritable.
It is suitable to developing the program.
Features
(1) Option switching by EPROM data
The option function of the LC865600 series can be specified by the EPROM data.
LC86E5632 can be checked the function of the trial pieces using the mass production board.
(2) Internal one-time EPROM capacity : 32768 bytes
(3) Internal RAM capacity
: 512 bytes
