Technical Context

The MC908GZ60CFUE implements the HCS08 CPU core with enhanced addressing modes and a 16-bit index register, supporting efficient C-language execution and interrupt latency as low as 5 cycles. Its Clock Generator Module (CGM) integrates a crystal oscillator, PLL with programmable multiplier (×1–×32), and automatic bandwidth control for stable clock synthesis across temperature and voltage variations.

It features two independent timer interface modules (TIM1/TIM2) with input capture, output compare, PWM generation, and cross-triggering capability; a dedicated MSCAN08 controller compliant with ISO 11898-1 (CAN 2.0B), supporting both standard and extended frames with message buffering and error handling; and a 24-channel 12-bit ADC with configurable sample-and-hold timing and hardware-triggered conversions synchronized to timer events.

FAQ

What is the maximum operating frequency of the MC908GZ60CFUE?

The MC908GZ60CFUE supports a maximum core frequency of 40 MHz, achieved via its integrated PLL-based Clock Generator Module (CGM) with programmable multiplication factors (×1–×32). This allows stable high-speed operation from low-cost 4–8 MHz crystals, and the actual system bus frequency is derived from the core clock with configurable division ratios. The MC908GZ60CFUE datasheet specifies timing parameters up to 40 MHz under 4.5–5.5 V and −40°C to +105°C conditions.

Does the MC908GZ60CFUE include a CAN controller?

Yes, the MC908GZ60CFUE integrates a fully compliant MSCAN08 controller supporting ISO 11898-1 (CAN 2.0B), including 32 message buffers, acceptance filtering, error confinement, and self-test mode. It provides dedicated CANTX (PTC0) and CANRX (PTC1) pins, requiring only an external physical-layer transceiver (e.g., TJA1042 or MC33886) for bus connection. The MC908GZ60CFUE uses hardware-managed CAN messaging to minimize CPU overhead and ensure deterministic response.

What ADC resolution and channel count does the MC908GZ60CFUE support?

The MC908GZ60CFUE features a 12-bit successive-approximation ADC with 24 input channels (AD0–AD23), mapped across Ports A, B, and G. It supports selectable voltage references (internal VDDAD/VSSAD or external VREFH/VREFL), programmable sample time, and hardware triggering from TIM or ESCI modules. The MC908GZ60CFUE ADC achieves ±1 LSB integral nonlinearity and supports left/right-justified data formats for flexible firmware integration.

Is the MC908GZ60CFUE pin-compatible with other GZ-series MCUs?

The MC908GZ60CFUE shares the same 80-pin LQFP package and core pinout with MC68HC908GZ48 and MC68HC908GZ32, but differences exist in peripheral mapping (e.g., ADC channel assignment, TIM channel availability) and Flash/RAM size. While mechanical footprint is identical, direct substitution requires validation of memory usage, peripheral initialization, and interrupt vector table alignment. The MC908GZ60CFUE datasheet confirms pin compatibility only within the GZ60 variant group.

What low-power modes are supported by the MC908GZ60CFUE?

The MC908GZ60CFUE supports Wait, Stop, and Normal modes. In Stop mode, current consumption drops to ≤10 µA with RAM retention, Timebase Module (TBM) running from LPO, and wake-up capability via CAN message, IRQ, or keyboard interrupt. Wait mode halts the CPU while peripherals remain active, drawing ~100 µA. Both modes are controlled via the STOP instruction and CONFIG register settings, and the MC908GZ60CFUE maintains full register state across wake-up events.
