CMOS IC
LC86E7148
8-Bit Single Chip Microcontroller
with the UVEPROM
Preliminary
Overview
The LC86E7148 is a CMOS 8-bit single chip microcontroller with UVEPROM for the LC867100 series. This
microcontroller has the function and the pin description of the LC867100 series mask ROM version, and 48K-byte EPROM.
The program data is rewritable. It is suitable to develop the program.
Features
(1) Option switching by EPROM data
The option function of the LC867100 series can be specified by the EPROM data.
LC86E7148 can be checked the functions of the trial pieces using the mass production board.
(2) Internal EPROM capacity
: 49152 bytes
(3) Internal RAM capacity
: 1152 bytes
Used EPROM or RAM capacity are equal ROM or RAM capacity of mask ROM version which applies LC86E7148.
