LC863232/28/24/20/16A
8-Bit Single Chip Microcontroller
Preliminary
Overview
The LC863232/28/24/20/16A 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 × 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
