8-bit 1-chip Microcontroller

Overview

The LC863264C/56C/48C/40C/32C/28C/24C/20C/16C 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 : 64K/56K/48K/40K/32K/28K/24K/20K/16K bytes

CGROM : 16K bytes

? On-chip RAM capacity : 640/512 bytes

? OSD RAM : 352×9 bits

? Closed-Caption TV controller and the on-screen display controller

? Closed-Caption data slicer

? Four channels×8-bit AD Converter

? Three channels×7-bit PWM

? Two 16-bit timer/counters, 14-bit base timer

? 8-bit synchronous serial interface circuit

? IIC-bus compliant serial interface circuit (Multi-master type)

? ROM correction function

? 16-source 10-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.
