Overview
The LC876596B and LC876580B 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 : LC876596B 96K bytes
                                                              LC876580B 80K bytes
   - On-chip RAM: 2048 bytes
   - VFD automatic display 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
   - Weak signal detector
   - 15-source 10-vectored interrupt system

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