The MCF51AC128ACFUE: It carries a 20-channel 12-bit ADC, CANbus, I²C, SCI, and SPI interfaces, and 54 GPIO lines in a 64-QFP package.
The 20 analog inputs with 12-bit resolution mean you can monitor multiple current-sense resistors, thermistors, and voltage dividers without external muxing.
The MCF51AC128ACFUE uses the Coldfire V1 background debug module (BDM) for programming and debugging. An external oscillator is required for the core clock.
Yes, the MCF51AC128ACFUE is ROHS3 compliant.
