Features & Applications
The MC9S12D microcontroller unit (MCU) is a 16-bit device composed of standard on-chip peripherals including a 16-bit central processing unit (HCS12 CPU), 2 asynchronous serial communications interfaces, an 8 channel IC/OC enhanced capture timer, two 8-channel, 10-bit analog-to-digital converters (ADC).

It has 8-channel pulse-width modulator (PWM), 20 discrete digital I/O lines, and an 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. The inclusion of a PLL circuit allows power consumption and performance to be adjusted to suit operational requirements.
