Overview
The LC87F72C8A is an 8 bit single chip microcontroller with the following on-chip functional blocks :
   - CPU: operable at a minimum bus cycle time of 100 ns
   - 128K bytes flash ROM (on-board rewritable)
   - On-chip RAM: 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.
