MC9S12DG256MFUE Description
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 is 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.
