Overview
The LC875164A/48A/32A 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/48K/32K bytes ROM
   - 1024 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
   - two synchronous serial I/O ports (with automatic block transmit/receive function)
   - one asynchronous/synchronous serial I/O port
   - 12-bit PWM × 2
   - 8-channel × 8-bit AD converter
   - high speed 8-bit parallel interface
   - 19-source 10-vectored interrupt system

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