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
