Overview
The LC863432/28/24/20/16A are 8-bit single chip microcontrollers with the following on-chip functional blocks:
   - CPU : Operable at a minimum bus cycle time of 0.424µs
   - On-chip ROM capacity
      Program ROM : 32K/28K/24K/20K/16K bytes
      CGROM : 16K bytes
   - On-chip RAM capacity : 512 bytes
   - OSD RAM : 352 × 9 bits
   - Closed-Caption TV controller and the on-screen display controller
   - Closed-Caption data slicer
   - Four channels × 6-bit AD Converter
   - Three channels × 7-bit PWM
   - 16-bit timer/counter, 14-bit base timer
   - IIC-bus compliant serial interface circuit (Multi-master type)
   - ROM correction function
   - 11-source 8-vectored interrupt system
   - Integrated system clock generator and display clock generator
      Only one X’tal oscillator (32.768kHz) for PLL reference is used for both generators
      TV control and the Closed Caption function
   All of the above functions are fabricated on a single chip.
