MC68HLC908QY1CDW 概要
What is an HC08 microcontroller: The 8-bit microcontroller is a single-chip computer core built around a CISC (Complex Instruction Set Computer) Von Neumann architecture that shares one memory bus for both program and data. Within the broader MCU taxonomy it sits below 32-bit Cortex-M devices but above 4-bit legacy controllers, offering simpler tool chains, lower power, and lower cost per unit of processing throughput. The M68HC08 family in particular is a direct evolution of the earlier M68HC05 line, gained wide industrial adoption in the 1990s/2000s, and now lives on as a long-lifecycle part for brownfield designs.
Key features of the MC68HLC908QY1CDW include 13 general-purpose I/O lines, an internal 8 MHz oscillator (2 MHz bus rate when the internal clock generation is used), on-chip in-system programmable FLASH, a dedicated 16-bit timer, and an integrated 5-channel ADC. The "HLC" prefix denotes the low-cost line and the device supports industrial temperature operation with a standard peripheral set covering basic timing and analog conversion.
The device is built on a mature CMOS process with FLASH technology that supports in-circuit programming. The standard M68HC08 CPU core offers a CISC instruction set with multiple addressing modes, making code generated for legacy HC05 sources portable and shortening firmware porting effort for engineers maintaining older product lines.
Typical applications include sensor signal conditioning, low-end consumer appliances, simple motor-control loops, white-goods user-interface boards, and industrial control modules where a small footprint and reliable FLASH programmability outweigh the need for higher throughput. The industrial-temperature grade makes the device suitable for automotive under-hood subsystems and factory-automation peripherals. Compared with newer Cortex-M0+ MCUs, the HC08 family remains attractive for designs where firmware portability and 5V-tolerant I/O matter more than raw performance.
When designing with this device, ensure the regulated supply rail meets the device's VDD tolerance and that the in-system programming pins (IRQ/PTB0 area) are accessible during production testing. Hardware designers should also budget for the internal oscillator tolerance if precise timing is required.

主な用途
MC68HLC908QY1CDW の用途: 6 件s: Appliance Control Boards, Industrial Sensor Modules, Low-End Consumer Electronics, Simple Motor Control, White-Goods User Interface, Automotive Body Modules.
Appliance Control Boards
The MC68HLC908QY1CDW fits appliance-control boards because its 13 GPIO pins can drive relays, triac interfaces, and LED indicators while its 5-channel ADC reads temperature sensors and potentiometer inputs. The 1.5 KB FLASH holds small state-machine firmware typical of washing-machine user-interface boards, and the 8 MHz core executes scheduled tasks within the interrupt latency budget of a household appliance. The industrial temperature grade tolerates the under-cabinet environment where moisture and temperature swings occur.
おすすめ
Industrial Sensor Modules
Sensor modules in factory automation leverage the MC68HLC908QY1CDW's 5-channel ADC to read analog sensor outputs and its 13 GPIO pins to drive digital isolators, RS-485 transceivers, and indicator LEDs. The CISC instruction set executes sensor-fusion math efficiently at 8 MHz, and the small 16-SOIC footprint allows placement in confined sensor housings. Industrial temperature grade supports -40C to +85C operation typical of factory floors.
おすすめ
Low-End Consumer Electronics
Toys, remote controls, and consumer gadgets use the MC68HLC908QY1CDW because the small 16-SOIC package, low price point, and 1.5 KB FLASH provide sufficient capability for button-scan firmware, IR protocol handling, and LED patterns. The internal oscillator option reduces BOM cost by eliminating external crystals, and the HC08's mature toolchain lets manufacturers port firmware between SKUs without retooling assembly lines. The simple peripheral set keeps the design cycle short and the BOM minimal.
おすすめ
Simple Motor Control
Small DC motor and stepper control loops fit the MC68HLC908QY1CDW where the on-chip 16-bit timer generates PWM signals while the 5-channel ADC measures back-EMF or current sense. Closed-loop control at modest speeds runs comfortably in 1.5 KB of FLASH, and the 13 GPIO pins drive H-bridge enable lines and direction logic. Industrial temperature and the robust HC08 silicon make this device a fit for pumps, fans, and small actuator modules.
おすすめ
White-Goods User Interface
White-goods human-machine interfaces benefit from the MC68HLC908QY1CDW because the device scans keypads, drives 7-segment or matrix displays, and serializes parameters to a host controller. The HC08 instruction set handles display multiplexing directly in the timer interrupt, and the small 16-SOIC outline simplifies routing around display and keypad areas on the front-panel PCB. The industrial temperature grade supports under-counter appliance environments.
おすすめ
Automotive Body Modules
Body-electronics modules such as mirror controllers, seat switches, and lighting controls can be built around the MC68HLC908QY1CDW where 13 GPIO pins and a 5-channel ADC are sufficient for sensing and PWM driving. The industrial temperature grade handles cabin-class thermal loads, and the small SOIC-16 package eases routing in the distributed body-network topology typical of pre-LIN vehicles. Although not AEC-Q100 qualified, the part is widely used in legacy automotive body controllers built before the LIN/CAN transition.

設計ノート
Estimated: at 8 MHz internal bus and 5 V VDD, the HC08 QY1 supply current is in the single-digit mA range when peripherals are idle. Decoupling should use a 100 nF ceramic plus a 1-10 uF bulk capacitor placed within 5 mm of the VDD pin; placing the bulk capacitor further away risks VDD sag during high-current GPIO switching.
Keep the RST line short and add a 10 kohm pull-up plus a 100 nF cap to ground so that power-on reset behavior is well-defined. The MON08 programming pins (often shared with IRQ) need accessible test pads or header so production programming does not require rework; placing these pads on the board edge minimizes fixture cost.
A common pitfall on HC08 designs is forgetting to configure the internal oscillator trim register, which can shift the bus frequency by more than the UART baud tolerance. Program the trim value during INIT and store the production calibration in a reserved FLASH location. Additionally, do not exceed 5 V on any GPIO when the device is unpowered, since parasitic ESD paths can latch the part into a high-current state.
コンプライアンス情報
RoHS, REACH, lead-free and halogen-free status were not explicitly listed in the verified web snippets; engineers should request the compliance report directly from NXP for production documentation. The part is not AEC-Q100 qualified and is therefore intended for industrial/consumer applications rather than automotive safety functions.
