NXP Semiconductors MC908AZ60AVFUER

Overview

MC908AZ60AVFUER from NXP (formerly Freescale) is an 8-bit HCS08 microcontroller featuring 60 KB on-chip FLASH, 2 KB RAM, and integrated CAN 2.0A/B controller. It operates at up to 40 MHz bus speed with internal PLL clock generation, supports 5V operation, and includes 10-bit ADC, SPI, SCI, and programmable timers - deployed in automotive body control modules and industrial sensor nodes.

For engineers reviewing the MC908AZ60AVFUER datasheet, MC908AZ60AVFUER pinout, MC908AZ60AVFUER application, or MC908AZ60AVFUER equivalent, key selection criteria include CAN interface support, 60 KB FLASH endurance (100k erase/write cycles), VDD = 4.5–5.5 V operation, and QFP-80 package compatibility for ECU-level integration.

Technical Context

The MC908AZ60AVFUER implements the HCS08 CPU core with enhanced BDM debug interface, dual FLASH blocks (FLASH-1/FLASH-2) enabling background programming, and independent EEPROM-1/EEPROM-2 modules each offering 2 KB with 100k cycle endurance. Its System Integration Module (SIM) manages reset sources including COP watchdog, LVI, and illegal opcode detection.

Integrated peripherals include MSCAN08 CAN controller with message buffers and acceptance filtering, 10-bit 16-channel ADC with configurable sample time, two 16-bit timer modules (TIMA/TIMB), and a Clock Generator Module (CGM) supporting crystal oscillator + PLL multiplication (×1 to ×32) for precise bus clock derivation.

FAQ

What is the maximum operating frequency of the MC908AZ60AVFUER?

The MC908AZ60AVFUER achieves a maximum bus frequency of 40 MHz using its internal PLL to multiply an external crystal input (e.g., 4 MHz ×10). This frequency governs instruction execution, peripheral timing, and ADC sampling rate - all synchronized to the derived bus clock. The MC908AZ60AVFUER datasheet specifies timing margins under worst-case voltage and temperature conditions to ensure reliable operation at this rate.

Does the MC908AZ60AVFUER support in-system programming (ISP)?

Yes, the MC908AZ60AVFUER supports in-system programming via its Background Debug Mode (BDM) interface using standard Freescale BDM tools. Both FLASH-1 and FLASH-2 blocks can be reprogrammed while the device is soldered on the target board, enabling field firmware updates without removing the MC908AZ60AVFUER from the PCB.

How many CAN message buffers does the MC908AZ60AVFUER MSCAN08 module provide?

The MSCAN08 controller in the MC908AZ60AVFUER provides eight full-message buffers - four transmit and four receive - each with dedicated ID, DLC, and data registers. This allows concurrent handling of multiple CAN identifiers without software arbitration overhead, critical for deterministic response in automotive networks.

What is the endurance rating of the EEPROM modules in the MC908AZ60AVFUER?

Both EEPROM-1 and EEPROM-2 modules in the MC908AZ60AVFUER are rated for 100,000 erase/write cycles per block, with individual block protection configurable via dedicated control registers. This endurance supports long-term data logging and calibration storage in applications like infusion pumps and sensor nodes where write frequency is moderate but reliability is critical.

Can the MC908AZ60AVFUER operate from a single 5 V supply without external regulators?

Yes, the MC908AZ60AVFUER is fully specified for 4.5 V to 5.5 V operation and integrates internal voltage regulation for core logic and I/O. It requires only external decoupling capacitors on VDD/VSS and separate analog filtering on VDDA/VSSA - eliminating need for external DC-DC or LDO regulators in standard 5 V automotive or industrial systems.
