MC81F4204
8 bit MCU with 12-bit A/D Converter
1. OVERVIEW
1.1 Description
MC81F4204 is a CMOS 8 bit MCU which provides a 4K bytes FLASH-ROM and 192 bytes RAM.
It has following major features,
12 bit ADC : It has 10 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
