MC80F0424/0432/0448
MC80C0424/0432/0448
CMOS SINGLE-CHIP 8-BIT MICROCONTROLLER
WITH 10-BIT A/D CONVERTER AND UART
1. OVERVIEW
1.1 Description
The MC80F0424/0432/0448 is advanced CMOS 8-bit microcontroller with 48K/32K/24K bytes of ROM(FLASH). This is a powerful mi-
crocontroller which provides a highly flexible and cost effective solution to many embedded control applications. This provides the fol-
lowing standard features : 24K/32K/48K bytes of ROM(FLASH), 1.5K bytes of RAM, 8/16-bit timer/counter, watchdog timer, watch
timer, 10-bit A/D converter, 8-bit Serial Input/Output, UART, 6-bit buzzer driving port, 10-bit PWM output and on-chip oscillator and
clock circuitry. It also has 8 high current I/O pins with typical 20mA. In addition, the MC80F0424/0432/0448 supports power saving modes
to reduce power consumption.
