The S9S12D64J4CFUE and MC9S12D are 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 S9S12D64J4CFUE and MC9S12D have 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.
