Overview
The LC875064B/56B/48B microcontroller is 8-bit single chip microcontroller with the following on-chip functional blocks:

    - CPU: Operable at a minimum bus cycle time of 100ns
    - 64K/56K/48K bytes ROM
    - 2048 byte RAM
    - two high performance 16 bit timer/counters (can be divided into 8 bit units)
    - two 8 bit timers with prescalers
    - timer for use as date/time clock
    - one synchronous serial I/O ports (with automatic block transmit/receive function)
    - one asynchronous/synchronous serial I/O port
    - 12-bit PWM × 2
    - 3-channel × 8-bit AD converter
    - high speed 8-bit parallel interface
    - 16-source 10-vectored interrupt system

All of the above functions are fabricated on a single chip.
