描述 Description

MC81F4x15 is a CMOS 8 bit MCU which provides a 16K bytes FLASH-ROM and 512 bytes RAM.

It has following major features,

12 bit ADC : It has 15 ch A/D Converter which can be used to measure minute electronic voltage and

currents.

810 Core : Same with ABOV’s 800 Core but twice faster. 800 Core use a divided system clock but

810 Core use a system clock directly

Power Consumption – Sub Active Mode: To decrease the power consumption, It can be operated with

sub clock( 32.768KHz ).
