NXP Semiconductors MC908GZ60CFUER

Overview

MC908GZ60CFUER from NXP (formerly Freescale) is an 8-bit HCS08 microcontroller with 60 KB on-chip Flash, 2 KB RAM, and integrated MSCAN08 CAN controller, ADC, ESCI, SPI, and TIM modules. It operates at up to 40 MHz core frequency, supports 5 V operation, and targets automotive body electronics, industrial control, and CAN-based sensor nodes.

For engineers reviewing the MC908GZ60CFUER datasheet, MC908GZ60CFUER pinout, MC908GZ60CFUER application, or MC908GZ60CFUER equivalent, key selection criteria include CAN 2.0A/B compliance, 24-channel 10-bit ADC with hardware averaging, PLL-based clock generation with CGMXCLK output, and support for stop/wait low-power modes with wake-up via IRQ, KBI, or CAN bus activity.

Technical Context

The MC908GZ60CFUER implements the CPU08 core with enhanced addressing modes and a 16-bit index register. Its Clock Generator Module (CGM) integrates a crystal oscillator, PLL with programmable multiplier (×1–×32), and base clock selector enabling flexible system clock derivation from internal or external sources.

The MSCAN08 controller supports full CAN 2.0A/B protocol with three message buffers, programmable bit timing, and automatic retransmission. The ESCI module provides LIN 1.3-compliant serial communication with automatic baud rate detection and break generation-critical for automotive sub-networks.

FAQ

What is the maximum operating frequency of the MC908GZ60CFUER core?

The MC908GZ60CFUER CPU08 core supports a maximum bus clock frequency of 40 MHz. This is achieved via the integrated PLL-e.g., using an 4 MHz crystal with ×10 multiplication yields 40 MHz BUSCLK. The core executes instructions at 1–2 cycles per instruction, enabling deterministic real-time response critical for CAN message scheduling and ADC sampling deadlines in the MC908GZ60CFUER.

Does the MC908GZ60CFUER support CAN FD or only classical CAN?

The MC908GZ60CFUER implements the MSCAN08 controller, which supports only Classical CAN (ISO 11898-1, CAN 2.0A/B) at up to 1 Mbit/s. It does not support CAN FD features such as flexible data-rate, extended data length, or CRC enhancements. For CAN FD, designers should consider NXP's S32K1xx or Kinetis KV series, not the MC908GZ60CFUER.

How many ADC channels does the MC908GZ60CFUER provide, and what is their resolution?

The MC908GZ60CFUER features a 24-channel, 10-bit successive approximation register (SAR) ADC. Channels map across Ports A, B, and G (AD0–AD23). Conversion time is 12.5 µs per sample at maximum speed, and hardware averaging across 2–8 samples per channel is supported to improve effective resolution without CPU intervention-key for stable sensor readings in noisy automotive environments using the MC908GZ60CFUER.

Is the MC908GZ60CFUER pin-compatible with other devices in the GZ family?

Yes-the MC908GZ60CFUER shares identical 64-pin LQFP pinout and electrical characteristics with MC68HC908GZ48 and MC68HC908GZ32. Differences are limited to Flash size (60/48/32 KB) and RAM (2 KB across all), allowing drop-in replacement during design iteration or cost optimization without PCB changes-confirmed by Table 22-1 and Figure 22-1 in the MC68HC908GZ60 Rev. 6 datasheet for the MC908GZ60CFUER.

What debug and programming interfaces does the MC908GZ60CFUER support?

The MC908GZ60CFUER supports background debug mode (BDM) via a single-wire interface using the BKGD pin (shared with Port D pin 7). This enables full-speed debugging, flash programming, and real-time register inspection without halting execution. No JTAG or SWD is supported. Development tools include the NXP DEMO9S08GZ60 evaluation board and CodeWarrior IDE-standard for all HCS08 devices including the MC908GZ60CFUER.
