Overview
The LC877264A, LC877256A and LC877248A are 8 bit single chip microcontrollers with the following on-chip functional blocks :
    - CPU: operable at a minimum bus cycle time of 100 ns
    - On-chip ROM Maximum Capacity : LC877264A 64K bytes
        LC877256A 56K bytes
        LC877248A 48K bytes
    - On-chip RAM capacity: 2048 bytes
    - LCD controller / driver
    - 16 bit timer / counter (can be divided into two 8 bit timers)
    - 16 bit timer / PWM (can be divided into two 8 bit timers)
    - Timer for use as date / time clock
    - Synchronous serial I/O port (with automatic block transmit / receive function)
    - Asynchronous / synchronous serial I/O port
    - 12-channel × 8-bit AD converter
    - Small signal detector
    - 14-source 10-vectored interrupt system

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