MC9S12D64CFUER

MCU 16Bit HCS12 CISC 64KB Flash 2.5V/5V 80Pin PQFP T/R

Overview

The MC9S12D is a 16-bit MCU composed of standard on-chip peripherals, including:

* Two asynchronous serial communications interfaces

* 8-channel IC/OC enhanced capture timer

* Two 8-channel, 10-bit analog-to-digital converters ADC

* 8-channel pulse-width modulator PWM

* 20 discrete digital I/O lines

* Inter-IC Bus

System resource mapping, clock generation, interrupt control and bus interfacing are managed by the System Integration Module SIM.

The MC9S12D has full 16-bit data paths throughout. However, the external bus can operate in an 8-bit narrow mode so single 8-bit wide memory can be interfaced for lower cost systems.

A PLL circuit allows power consumption and performance to be adjusted.
