FAQ

What is the maximum operating frequency of the MC908GR60ACFUE?

The MC908GR60ACFUE achieves a maximum core frequency of 40 MHz using its integrated PLL with programmable multiplication factor (×1 to ×32). This is derived from an external 1–8 MHz crystal or internal RC oscillator. The actual achievable frequency depends on VDD voltage and ambient temperature, with full 40 MHz operation guaranteed at 5.0 V and 25°C per the datasheet's AC electrical specifications.

Does the MC908GR60ACFUE support LIN communication natively?

Yes, the MC908GR60ACFUE supports LIN 2.0 communication natively through its Enhanced Serial Communications Interface (ESCI). It provides automatic sync-break detection, 13-bit identifier recognition, and configurable baud rates from 1.2 to 20 kbps - eliminating the need for external LIN transceivers in compliant slave-node implementations.

How many ADC channels does the MC908GR60ACFUE have, and what is their resolution?

The MC908GR60ACFUE features a 10-bit successive-approximation ADC with 16 input channels (AD0–AD7 on Port B, plus additional channels mapped to Port A and Port E). It supports single-ended and differential conversion modes, with a maximum sampling rate of 250 kSPS and built-in result justification (left/right-aligned) for direct DSP interface.

What low-power modes are available on the MC908GR60ACFUE?

The MC908GR60ACFUE supports two primary low-power modes: Wait Mode (CPU halted, peripherals active, ~10 µA typical) and Stop Mode (all clocks stopped except LPO, ~1.5 µA typical). Both modes retain RAM contents and allow wake-up via IRQ, KBI, ADC end-of-conversion, or timer overflow - critical for battery-operated sensor nodes and portable medical devices.

Is the MC908GR60ACFUE pin-compatible with other HCS08 family members like the MC68HC908GR16A?

No, the MC908GR60ACFUE is not pin-compatible with the MC68HC908GR16A. While both belong to the HCS08 family and share architectural similarities, the MC908GR60ACFUE uses a 64-pin QFP package with expanded peripheral mapping (e.g., dual timers, more ADC channels, ESCI), whereas the MC68HC908GR16A uses a 44-pin SOIC/QFP. Pin assignments, power domains, and I/O multiplexing differ significantly between the two.
