MC908AZ60ACFUER - 8-Bit HC08 MCU, 60KB Flash, 64-QFP | NXP
MPN: MC908AZ60ACFUER ✗ Cuối đờiMC908AZ60ACFUER Tóm tắt
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.

Ghi chú thiết kế
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.
