MC908GZ60CFAE - 8-bit HC08 MCU 60KB Flash 48-LQFP | NXP
MPN: MC908GZ60CFAE ✗ סוף ייצורMC908GZ60CFAE סקירה
A microcontroller (MCU) is a single-chip computer that integrates a CPU, memory (Flash/RAM), and programmable peripherals onto one silicon die. The HC08 family is a long-running 8-bit architecture from Motorola/Freescale (now NXP) designed for deterministic control in cost-constrained applications such as body electronics, HVAC controls, and appliance motor control. Within the taxonomy: 8-bit microcontroller -> microcontroller unit (MCU) -> embedded processor -> semiconductor device. The MC908GZ60CFAE belongs to the HC908GZ sub-family which adds CAN 2.0A/B interface support.
Key features include 60KB Flash program memory, 2KB RAM, 8-channel 10-bit ADC, CAN 2.0A/B controller, SCI and SPI serial interfaces, a 4-channel 16-bit timer, and an integrated clock generator module. The 48-LQFP package provides 40 general-purpose I/O pins with 5V tolerance, supporting direct LED drive and logic-level interface without external translation.
The device uses a Harvard-style architecture with a unified address space for code and data plus a dedicated Flash controller. The CPU08 core executes most instructions in two bus cycles, and the built-in in-circuit programming (ICP) interface allows Flash updates via a serial monitor without an external programmer.
Typical applications include automotive body control modules, HVAC fan/actuator drivers, industrial sensor hubs, appliance control boards, and CAN-connected remote I/O nodes. The wide 5V supply tolerance and -40C to +85C operating range suit underhood and industrial cabinet environments.
When designing with this part, ensure the 48-LQFP footprint is allocated with proper thermal copper land and that the ICP interface pins are accessible for in-circuit firmware updates. The 5V-only supply means a separate regulator is required when the system bus runs at 3.3V.

יישומים טיפוסיים
MC908GZ60CFAE מתאים עבור 6 יישוםs: Automotive Body Control Module, HVAC Fan and Actuator Control, Industrial Sensor Hub with CAN, Appliance Control Board (White Goods), CAN-Connected Remote I/O Node, Security and Access Control Panel.
Automotive Body Control Module
The MC908GZ60CFAE is well-suited for body control modules (BCMs) in mid-2000s and 2010s vehicles where cost-optimized 8-bit compute is sufficient. Its integrated CAN 2.0A/B controller supports body-network communication at up to 1 Mbps, while the 60KB Flash accommodates BCM application code for lighting, door-lock, and turn-signal coordination. The 40 GPIO pins provide ample headroom for relay and LED driver control. With 4.5-5.5 V supply tolerance and -40 C to +85 C operating range, the part handles cabin and trunk-mounted environments. Compared with newer S12 successors, the GZ60CFAE is preferred for cost-down BCM variants. The 8-channel 10-bit ADC supports battery voltage, ambient light, and temperature sensor reads. Pairing with an NXP TJA1042 CAN transceiver completes the physical-layer interface.

HVAC Fan and Actuator Control
HVAC systems for automotive and industrial enclosures benefit from the MC908GZ60CFAE's 4-channel 16-bit timer for PWM generation, which drives blower motors, mode-door actuators, and flap-position servos. The 60KB Flash holds HVAC control algorithm code plus calibration tables for the blower speed curve, while 2KB RAM stores runtime state. The 10-bit ADC reads cabin temperature, evaporator temperature, and sun-load sensor inputs to compute airflow targets. With a 48-LQFP footprint, the MCU fits on a compact PCB alongside motor-driver stages. The 5V supply integrates with the existing HVAC control board power rail. Compared to motor-control-specific MCUs, the GZ60CFAE provides flexibility for mixed HVAC and lighting functions on a single module.
מומלץ
Industrial Sensor Hub with CAN
Distributed industrial sensor hubs deployed on factory floors use the MC908GZ60CFAE to aggregate analog and digital sensor inputs and forward them over CAN. The 8-channel 10-bit ADC monitors pressure, flow, and temperature transducers, while GPIO reads discrete sensors. The on-chip CAN 2.0A/B interface at 1 Mbps provides deterministic field-bus communication in noisy industrial environments. With 60KB Flash, the firmware can include CANopen or DeviceNet stack fragments for protocol translation. The -40 C to +85 C operating temperature range suits unconditioned factory cabinets and outdoor cabinets. Pairing with an isolated CAN transceiver (e.g., ISO1050) provides robust EMC immunity for industrial deployments.
מומלץ
Appliance Control Board (White Goods)
Washing machines, dryers, and dishwashers use the MC908GZ60CFAE for main control functions where cost and reliability are paramount. The 60KB Flash stores motor-control algorithms, user-interface state machines, and fault-diagnostic logs, while 2KB RAM is sufficient for runtime data. The 4-channel 16-bit timer generates PWM for motor and valve control. The 8-channel 10-bit ADC reads water-level, temperature, and motor-current sensors. Compared to dedicated motor-control MCUs, the GZ60CFAE offers more general-purpose GPIO for keypad and display driving. With 5V tolerance, the device interfaces directly with TTL-level display drivers and triac-control optocouplers without external level shifters.
מומלץ
CAN-Connected Remote I/O Node
Remote I/O modules distributed across industrial machines use the MC908GZ60CFAE as a cost-effective CAN node controller. The on-chip CAN 2.0A/B interface supports both standard and extended identifiers, enabling compatibility with classic CANopen and DeviceNet node IDs. The 40 GPIO pins provide ample headroom for mixed digital and analog I/O, while 60KB Flash hosts the CAN protocol stack and I/O mapping logic. The 48-LQFP package allows compact module designs alongside CAN transceivers and isolated DC/DC converters. The part is preferred over newer S08/S12 successors for cost-optimized nodes where legacy firmware investment is significant.
מומלץ
Security and Access Control Panel
Security alarm panels and access-control readers use the MC908GZ60CFAE for keypad scanning, sensor supervision, and communication with central monitoring stations. The 60KB Flash supports keypad mapping, encrypted credential storage, and event-logging algorithms, while 2KB RAM holds transient state. The 8-channel 10-bit ADC reads PIR motion sensors, smoke-detector interfaces, and battery-backup voltage. UART (SCI) interfaces with GSM/GPRS or Ethernet modules for central-station communication, while GPIO drives sirens and relay outputs. With -40 C to +85 C range, the MCU handles indoor and sheltered outdoor cabinets. The 5V supply integrates with conventional alarm-panel power buses.

הערות תכנון
The MC908GZ60CFAE requires a stable 5V supply; per HC08GZ datasheet the POR (power-on-reset) and LVI (low-voltage inhibit) circuits protect against brown-out conditions. A 78M05 or TPS7A4001 LDO with a 100 nF decoupling capacitor placed within 5 mm of the VDD pin is recommended. Add a 10 uF bulk capacitor at the LDO output and a ferrite bead if the supply is shared with switching converters to prevent MCU noise coupling.
Programming the on-chip Flash requires the monitor ROM to be enabled by holding IRQ high during reset; users omitting this step see 'no communication' on the ICP interface. The HC08GZ datasheet revision flags IRQ/VPP pin handling. For production firmware updates, route IRQ to a dedicated test-point header. Additionally, the CAN bit-timing registers (CANBTR0/CANBTR1) must be loaded AFTER the oscillator is stable - configuring them before oscillator lock causes CAN bus errors.
PCB layout for the 48-LQFP requires a copper land beneath the exposed pad area (if present on this variant) connected to VSS for thermal dissipation; without it, junction temperature can rise 15-20 C above ambient in enclosed modules. Keep CAN_TX/CAN_RX traces short and matched within 5 mm to avoid bit-timing skew. Place the 4.7 kohm CAN bus termination ONLY at the physical ends of the bus - never at intermediate nodes. Use a ground guard trace between CAN signals and switching nodes.
Estimated: at maximum 8 MHz bus clock and 5V supply, the MCU draws approximately 25 mA active current. With 48-LQFP theta_JA around 70 C/W, the junction temperature rise in still air is approximately 8.8 C above ambient at full activity. For enclosed automotive cabin environments with ambient up to 85 C, junction stays within the -40 C to +125 C operating limit. Add a copper pour under the LQFP to lower theta_JA to approximately 50 C/W if thermal margin is critical.
