16Bit MCU, S12 core, 128KB Flash, 25MHz, -40/+125℃, Automotive Qualified, QFP 112
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.
