MC908AZ60ACFUER Übersicht
What is an HC08 microcontroller? The HC08 (or M68HC08) is Freescale/NXP's family of 8-bit microcontrollers that succeeded the original 68HC05 line. The HC08 is a CISC architecture using an enhanced CPU08 core with 16-bit internal index/accumulator operations, a 64KB linear address space, and broad peripheral integration. HC08 devices sit within the broader taxonomy: microcontroller unit (MCU) -> 8-bit MCU -> HC08 family -> HC08AS/AZ automotive sub-family, and remain in service for cost-sensitive automotive body and chassis applications.
Key features include 60KB (60K x 8) FLASH program memory, 2KB EEPROM, 1KB on-chip RAM, an 8-channel 8-bit ADC, two timer/PWM modules, CAN 2.0A/B interface, SCI (UART), and SPI. The 64-pin QFP (14x14 mm) package offers generous I/O count for body-control and instrument-cluster designs. According to the manufacturer datasheet, the part operates over -40C to +125C and is qualified to AEC-Q100 for automotive applications.
The HC08AS/AZ family uses the same CPU08 instruction set as the rest of the HC08 line, providing upward-compatible firmware development with other family members. The on-chip FLASH allows in-application reprogramming via the standard NXP monitor ROM, simplifying field updates. Internal RC oscillator and PLL options reduce external component count. The 5V supply rail matches conventional automotive body controllers.
Typical applications include automotive body controllers, instrument clusters, HVAC control modules, lighting controllers, industrial sensor hubs, and CAN node endpoints. The integrated CAN 2.0B controller makes the part particularly well suited to distributed in-vehicle networks where multiple ECUs communicate on a single CAN bus.
When designing with this device, ensure the monitor ROM is properly invoked during in-system programming by holding the IRQ pin low at reset. Decouple VDD/VSS with 100nF ceramic capacitors placed within 5mm of each supply pin, and provide a stable 5V rail capable of sourcing 50mA plus I/O sink current.
This page synthesizes distributor inventory, parametric alternatives, and practical design notes not found in the manufacturer datasheet, including same-family AZ/AS part variations and the most common engineering pitfalls for HC08 firmware developers.

Typische Anwendungen
MC908AZ60ACFUER ist geeignet für 6 Anwendungs: Automotive Body Control Module, Instrument Cluster Controller, HVAC Control Module, Lighting Control ECU, Industrial CAN Node Endpoint, Sensor Hub Module.
Automotive Body Control Module
The MC908AZ60ACFUER is well-suited for automotive body control modules where the integrated CAN 2.0B interface connects the ECU to the in-vehicle network. The 60KB FLASH accommodates typical BCM firmware (door locks, lighting, wipers, mirror control) and the 2KB EEPROM stores configuration and diagnostic data. AEC-Q100 qualification and -40C to +125C operation match underhood and cabin environments.
Empfohlen
Instrument Cluster Controller
The MC908AZ60ACFUER's 8-channel 8-bit ADC and 16-bit timer/PWM modules make it a practical choice for instrument cluster stepper-motor gauges and indicator LED drivers. The 60KB FLASH accommodates gauge logic, odometer storage in EEPROM, and CAN bus diagnostics. The 64-QFP package provides enough I/O for multiple gauge outputs while keeping the PCB compact.
Empfohlen
HVAC Control Module
Climate control modules benefit from the MC908AZ60ACFUER's ADC channels for cabin temperature and blend-door position sensing, plus PWM timers for blower motor and actuator control. CAN connectivity enables integration with the vehicle's body network for shared setpoint and status data. The 60KB program memory comfortably fits typical HVAC state machines and PID control loops.
Empfohlen
Lighting Control ECU
Front-lighting and signal-lighting ECUs use the MC908AZ60ACFUER for PWM dimming of LED headlamps, daytime running lights, and turn signal control. The 16-bit timer/PWM modules provide precise LED current control while the CAN interface coordinates with other lighting ECUs. AEC-Q100 qualification ensures reliable operation across automotive temperature extremes.
Empfohlen
Industrial CAN Node Endpoint
Beyond automotive, the MC908AZ60ACFUER serves as a robust CAN node endpoint for industrial sensor hubs and machine controllers. The 5V supply tolerance and wide operating temperature suit factory floor environments. SPI and SCI allow sensor and operator-panel interfacing, while 60KB FLASH accommodates protocol stacks and application logic in a single chip.
Empfohlen
Sensor Hub Module
Distributed sensor hubs in vehicles and machinery use the MC908AZ60ACFUER to aggregate analog and digital sensor data and publish it on the CAN bus. The 8-channel ADC reads multiple sensor inputs, while EEPROM stores calibration constants. The HC08 core's deterministic interrupt response makes timing-sensitive sensor sampling predictable.

Designhinweise
Decouple each VDD/VSS pair with a 100nF ceramic capacitor placed within 5mm of the pins; add a 10uF bulk tantalum or aluminum polymer capacitor near the package. The HC08 core draws peak current during FLASH programming; insufficient decoupling causes programming failures and erratic ADC readings. Tie all VDD pins together and all VSS pins together on the PCB for lowest ground bounce.
Hold the IRQ pin low at reset to invoke monitor mode for in-application FLASH programming via the SCI interface. Releasing IRQ before the monitor firmware stabilizes aborts programming. For production firmware, ensure the IRQ pin has a defined logic state at reset to prevent unintended monitor-mode entry.
Route the OSC1/OSC2 crystal traces with short, symmetric paths and guard them with a ground pour to minimize EMI pickup. Place the crystal within 5mm of the MCU pins and avoid routing digital signal traces underneath. For CAN bus signals, route TxD/RxD as a differential pair with 120-ohm characteristic impedance and 100nF split termination at the transceiver input.
The 64-QFP package has a thermal resistance theta_JA of approximately 50 C/W, suitable for automotive ambient environments up to +85C with modest self-heating. At maximum I/O switching load, the part dissipates under 500mW; no heatsink is required. For underhood +125C operation, derate I/O drive strength and minimize simultaneous switching outputs to limit junction temperature rise.
ADC input traces should be kept short and guarded by analog ground; the ADC reference pins (VREFH/VREFL) require a 100nF bypass plus a 1-10uF bulk capacitor for low-noise 8-bit conversions. Avoid routing ADC traces parallel to digital switching signals to prevent crosstalk. If higher resolution is needed, route the analog signal to an external 12-bit ADC over SPI.
Compliance-Informationen
RoHS and REACH compliance per distributor listings (DigiKey, Mouser, Arrow). AEC-Q100 qualified per manufacturer datasheet and Arrow's automotive qualification statement. Halogen-free status not explicitly stated in available data.
