MC81F4x32
MC81F4x32
8 bit MCU with 12-bit A/D Converter
1. OVERVIEW
1.1 Description
MC81F4x32 is a CMOS 8 bit MCU which provides a 32K 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 ).
