It operates at up to 40 MHz bus frequency, supports LIN via ESCI, and targets automotive body electronics and industrial control systems requiring CAN communication and analog sensing.

For engineers reviewing the MC908GZ60CFJE datasheet, MC908GZ60CFJE pinout, MC908GZ60CFJE application, or MC908GZ60CFJE equivalent, key selection criteria include CAN 2.0A/B compliance, Flash memory size and block protection, ADC channel count and reference flexibility, low-power stop/wait modes with wake-on-CAN/IRQ, and oscillator PLL configuration for clock stability in harsh environments.

Technical Context

The MC908GZ60CFJE implements the HCS08 CPU core with enhanced addressing modes and a 16-level hardware stack. Its Clock Generator Module (CGM) integrates a crystal oscillator, PLL with programmable multiplier (×1–×32), and automatic acquisition/lock logic for stable 40 MHz bus clock generation from low-frequency crystals.

It features a dedicated MSCAN08 module compliant with ISO 11898-1:2003, supporting both standard and extended frames, message buffering, and automatic retransmission. The ESCI module provides LIN 2.0-compliant serial communication with automatic sync-break detection and configurable baud rate generation.

FAQ

What is the maximum bus frequency supported by the MC908GZ60CFJE?

The MC908GZ60CFJE supports a maximum bus frequency of 40 MHz, achieved through its integrated Clock Generator Module (CGM) with programmable PLL multiplier (×1 to ×32). This frequency is derived from an external crystal (1–8 MHz) or internal RC oscillator, and is confirmed in Section 4.3.2 and Table 21-1 of the Rev. 6 datasheet. The MC908GZ60CFJE maintains timing integrity across voltage (4.5–5.5 V) and temperature (−40°C to +125°C) ranges specified for automotive use.

Does the MC908GZ60CFJE include a hardware CAN controller?

Yes, the MC908GZ60CFJE integrates the MSCAN08 controller, a fully compliant CAN 2.0A/B module supporting standard and extended frames, 32 message buffers, automatic retransmission, and error confinement. This hardware accelerator offloads CAN protocol handling from the HCS08 CPU, enabling deterministic real-time messaging without software stack overhead. Details are in Chapter 12 of the MC908GZ60CFJE datasheet.

How many analog input channels does the ADC in the MC908GZ60CFJE support?

The MC908GZ60CFJE features a 10-bit successive-approximation ADC with 24 configurable analog input channels, mapped across Ports A (AD8–AD15), B (AD0–AD7), and G (AD16–AD23). Channel selection, conversion trigger sources (software, timer, or external), and result justification (left/right-aligned) are controlled via ADC registers described in Chapter 3. Reference voltage can be internally generated or externally applied via VREFH/VREFL pins.

What low-power modes are available on the MC908GZ60CFJE?

The MC908GZ60CFJE supports three primary low-power modes: Wait (CPU halted, peripherals active), Stop (all clocks stopped except RTC/LVI, 0.5 µA typical), and Monitor (debug-enabled Stop variant). Wake-up sources include IRQ, KBI, CAN activity, and timer events. These modes are detailed in Chapter 10 and electrically characterized in Section 21.5 (5.0-Vdc specs), ensuring suitability for battery-powered or energy-conscious automotive subsystems.

Is the MC908GZ60CFJE pin-compatible with other GZ-series MCUs like the MC908GZ48 or MC908GZ32?

Yes, the MC908GZ60CFJE shares identical pinout and package (64-pin LQFP) with MC908GZ48CFJE and MC908GZ32CFJE, as confirmed in Section 1.4 "Pin Assignments" and Figure 1-1 of the Rev. 6 datasheet. Functionally identical pins enable hardware reuse across memory variants; only Flash/RAM sizes differ (60/48/32 KB Flash, 2/1.5/1 KB RAM). This allows scalable design without PCB redesign.
