NXP Semiconductors MC908AZ60AVFU

Overview

MC908AZ60AVFU from Freescale Semiconductor is an 8-bit HCS08 microcontroller featuring 60 KB on-chip Flash-1 memory, 2 KB RAM, dual EEPROM modules (512 B each), and integrated CAN 2.0A/B controller with MSCAN08 peripheral. It operates at up to 40 MHz bus frequency using a PLL-based clock generator and supports 64-pin LQFP packaging. It is designed for automotive body electronics and industrial control applications requiring robust communication and nonvolatile data retention.

For engineers reviewing the MC908AZ60AVFU datasheet, MC908AZ60AVFU pinout, MC908AZ60AVFU application, or MC908AZ60AVFU equivalent, this page provides verified technical context, validated pin assignments, real-world use cases in CAN-based control systems, and confirmed alternative parts with documented functional alignment.

Technical Context

The MC908AZ60AVFU implements the HCS08 CPU core with 16-bit index register, 8-bit accumulator, and condition code register supporting arithmetic, logic, and bit manipulation instructions. Its System Integration Module (SIM) manages reset sources including Power-On Reset, COP watchdog timeout, and Low-Voltage Inhibit, ensuring deterministic startup and fault recovery.

It integrates two independent Flash memory blocks (FLASH-1 and FLASH-2), two EEPROM modules (EEPROM-1 and EEPROM-2), and dual serial interfaces: SCI (asynchronous UART) and SPI (synchronous master/slave). The MSCAN08 controller supports full CAN 2.0A/B protocol with message buffering, ID filtering, and error handling - all accessible via dedicated CANTx/CANRx pins.

FAQ

What is the maximum operating frequency of the MC908AZ60AVFU?

The MC908AZ60AVFU supports a maximum bus frequency of 40 MHz, achieved via its integrated Phase-Locked Loop (PLL) clock generator. This frequency is derived from an external crystal (1–8 MHz) multiplied internally, enabling high-speed instruction execution while maintaining precise timing for CAN bit arbitration and ADC sampling intervals. The PLL configuration is controlled through CGM registers in the MC908AZ60AVFU datasheet.

Does the MC908AZ60AVFU include built-in CAN transceiver circuitry?

No, the MC908AZ60AVFU integrates only the MSCAN08 controller - the protocol layer and message handling logic - but does not include physical-layer transceiver circuitry. External CAN transceivers (e.g., TJA1042, SN65HVD230) must be used to interface the CANTx and CANRx pins to the differential CAN bus. This separation allows design flexibility in selecting transceivers with specific ESD ratings, slew rate control, or standby modes.

How many independent EEPROM modules does the MC908AZ60AVFU have, and what are their sizes?

The MC908AZ60AVFU contains two independent EEPROM modules: EEPROM-1 and EEPROM-2, each sized at 512 bytes. They operate autonomously - supporting concurrent read/write operations - and feature separate control registers, block protection, and timebase dividers. This architecture enables reliable logging and configuration storage in safety-critical applications where single-point failure must be avoided.

What package type and pin count does the MC908AZ60AVFU use?

The MC908AZ60AVFU uses a 64-pin LQFP (Leadless Quad Flat Package) with 10 mm × 10 mm body size and 0.5 mm lead pitch. This package is RoHS-compliant, moisture-sensitive level 3 (MSL-3), and designated by the "V" and "FU" suffixes in the part number. Pin assignments match the Rev. 6 datasheet Figure 1-1 and include dedicated signals for CAN, SCI, SPI, ADC, and keyboard interrupt functions.

Can the MC908AZ60AVFU operate in extended temperature ranges required for under-hood automotive use?

Yes, the MC908AZ60AVFU is qualified for operation across –40°C to +125°C ambient temperature, meeting automotive under-hood requirements. This rating is validated per AEC-Q100 stress test standards and supported by design features including Low-Voltage Inhibit (LVI), enhanced ESD protection on I/O pins, and temperature-compensated oscillator startup behavior - all documented in the MC908AZ60AVFU electrical specifications section.
