LC863432A/28A/24A/20A/16A
8-Bit Single-Chip Microcontroller
Preliminary
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.
Note : This product includes the IIC bus interface circuit. If you intend to use the IIC bus interface, please
notify us of this in advance of our receiving your program ROM code order.
Purchase of SANYO IIC components conveys a license under the Philips IIC Patents Rights to use these
components in an IIC system, provided that the system conforms to the IIC Standard Specification as
defined by Philips.
