CMOS IC FROM 48K/40K/32K/28K/24K/20K/16K-byte, RAM 640/512-byte on-chip and 352 ×9-bit OSD RAM

Overview

The LC863448/40/32/28/24/20/16B 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 : 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 × 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

• 12-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.
