Overview

The LC864332A/28A/24A/20A/16A/12A microcontrollers are 8-bit single chip microcontrollers with the following on-chip functional blocks:

• CPU : Operable at a minimum bus cycle time of 0.5 µs

• On-chip ROM maximum capacity : 32K bytes

• On-chip RAM capacity : 384 bytes

• CRT display RAM : 640 × 9 bits

• Closed-caption TV controller and the on-screen display controller

• 16-bit timer/counter

• 4-channel × 5-bit A/D converter

• 8-bit synchronous serial-interface circuit

• Closed-caption data slicer

• 12-source 10-vectored interrupt system

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