Product details
Overview
MC68HC908GZ60VFU from NXP (formerly Freescale) is an 8-bit HCS08-core microcontroller with 60 KB on-chip FLASH-1, 2 KB RAM, integrated MSCAN08 CAN controller, 12-bit ADC with 24 input channels, and dual PLL-based clock generation supporting up to 40 MHz CPU operation. It features 64-pin LQFP packaging, hardware COP watchdog, and low-power stop/wait modes - deployed in automotive body control modules and industrial sensor nodes requiring CAN communication and analog signal acquisition.
For engineers reviewing the MC68HC908GZ60VFU datasheet, MC68HC908GZ60VFU pinout, MC68HC908GZ60VFU application, or MC68HC908GZ60VFU equivalent, key selection criteria include verified CAN 2.0A/B compliance, 12-bit ADC channel count and sampling rate, FLASH memory partitioning (FLASH-1/FLASH-2), CGM PLL lock time under voltage transients, and RST/IRQ interrupt latency in stop mode.
Technical Context
The MC68HC908GZ60VFU implements the HCS08 CPU core with enhanced addressing modes and a 16-level hardware stack. Its Clock Generator Module (CGM) integrates two independent PLLs: one for CPU clock (CGMXCLK) and another for bus/peripheral timing (CGMOUT), each configurable via dedicated multiplier and bandwidth registers.
It embeds a full-featured MSCAN08 controller compliant with ISO 11898-1, supporting both standard and extended frames, programmable bit timing, and three message buffers with priority arbitration. The ADC subsystem supports simultaneous sampling across multiple channels using internal multiplexing and configurable conversion sequences.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC9S08DZ60 | Same HCS08 core, 60 KB FLASH, but adds EEPROM, LIN interface, and enhanced debug support; no MSCAN08 - uses separate CAN module | LIN master capability and EEPROM make it suitable for gateway modules; lacks integrated CAN controller for pure CAN-node roles | Select MC9S08DZ60 only if LIN protocol support or non-volatile parameter storage is required alongside CAN communication |
| S9KEAZN64 | Kinetis E-series ARM Cortex-M0+, 64 KB FLASH, 8 KB RAM, CAN 2.0B, but requires external crystal and lacks integrated CGM PLL | Higher performance and modern toolchain support; however, lacks hardware LVI and dual-FLASH bank isolation for fail-safe updates | Choose S9KEAZN64 for new designs needing scalability and CMSIS compatibility; avoid when legacy HCS08 codebase or deterministic brown-out response is mandatory |
Compared with MC9S08DZ60 and S9KEAZN64, the MC68HC908GZ60VFU delivers superior integration for cost-sensitive CAN-only nodes - retaining hardware LVI, dual FLASH banks, and MSCAN08 in a single die without external components or software abstraction layers.

FAQ
What is the maximum operating frequency of the MC68HC908GZ60VFU?
The MC68HC908GZ60VFU supports a maximum CPU frequency of 40 MHz, achieved via its internal PLL-based Clock Generator Module (CGM). This frequency is derived from an external crystal (1–8 MHz) multiplied by programmable factors in the PLL Multiplier Select Registers. The CGM allows dynamic switching between crystal, PLL, and internal RC sources - enabling flexible power/performance trade-offs in real-time applications.
Does the MC68HC908GZ60VFU include a CAN controller?
Yes, the MC68HC908GZ60VFU integrates the MSCAN08 controller, a fully compliant CAN 2.0A/B module supporting standard and extended frames, programmable bit timing, and three message buffers with hardware priority arbitration. It operates at up to 1 Mbit/s and uses dedicated pins PTC6 (CANTX) and PTC7 (CANRX), eliminating the need for external CAN protocol ICs in basic node implementations.
How much FLASH memory does the MC68HC908GZ60VFU have, and how is it organized?
The MC68HC908GZ60VFU contains 64 KB of total on-chip FLASH memory, partitioned into 60 KB FLASH-1 and 4 KB FLASH-2. FLASH-1 stores primary application code and supports mass/page erase and block protection; FLASH-2 is typically reserved for boot code, calibration data, or firmware update staging - enabling safe over-the-air updates without corrupting active execution.
What is the ADC resolution and input channel count on the MC68HC908GZ60VFU?
The MC68HC908GZ60VFU features a 12-bit successive approximation register (SAR) ADC with 24 selectable analog input channels mapped across Ports A, B, G, and dedicated ADC pins. Conversion time is as fast as 10 µs per sample, and the module supports scan mode for automated sequential conversion across up to 16 channels - ideal for multi-sensor monitoring in automotive and industrial systems.
Is the MC68HC908GZ60VFU pin-compatible with other members of the GZ series?
No, the MC68HC908GZ60VFU is not pin-compatible with MC68HC908GZ48 or MC68HC908GZ32 variants. While all share the same 64-pin LQFP package and core peripheral set, differences in ADC channel mapping, CAN pin assignment, and port functionality require PCB layout revision when migrating between GZ-family members - confirmed by distinct pin function tables in Section 1.5 of the Rev. 6.0 datasheet.
