Z51F6412
CMOS SINGLE-CHIP 8-BIT MICROCONTROLLER
WITH 12-BIT A/D CONVERTER
1. Overview
1.1 Description
The Z51F6412 MCU is advanced CMOS 8-bit microcontroller with 64K bytes of Flash. This is
powerful microcontroller which provides a highly flexible and cost effective solution to many
embedded control applications. This provides the following features : 64K bytes of Flash, 256 bytes of
SRAM, 3K bytes of XRAM, general purpose I/O, 8/16-bit timer/counter, watchdog timer, watch timer,
SPI, USART, I2C, Calculator, on-chip POR and BOD, 12-bit A/D converter, buzzer driving port, 16-bit
PWM output, on-chip oscillator, and clock circuitry. The Z51F6412 MCU also supports power saving
modes to reduce power consumption.
