MC68HLC908QY4CDW 개요
An HC08 microcontroller is an 8-bit embedded processor within the broader microcontroller and semiconductor hierarchy. Its instruction set, memory resources, I/O, and timing behavior are designed for compact control systems rather than high-performance computing. The MC68HLC908QY4CDW combines a 4K x 8 Flash architecture with an 8 MHz clock capability, making it appropriate for products that require embedded program storage and modest processing throughput.
Key verified characteristics include the M68HC08 HC08 CPU, 8-bit data width, 8 MHz operation, 4 KB Flash memory organized as 4K x 8, and a 16-SOIC package. The manufacturer datasheet search result specifically states that the QY4 family is available in 16-pin packages. Additional specifications such as RAM size, I/O counts, timing ratings, voltage limits, temperature range, and peripheral details are not available in the supplied verified data and therefore require verification from the manufacturer datasheet before design release.
Typical applications for this device include small appliance controllers, sensor-interface modules, simple motor or relay-control boards, keypad interfaces, and industrial embedded-control products where an 8-bit CPU and nonvolatile program memory are sufficient. The 8 MHz clock provides a straightforward execution target for basic control logic, while Flash permits firmware to be stored directly on the device.
Designers should confirm the exact MC68HLC908QY4CDW pin assignment, supply-voltage range, memory map, reset behavior, oscillator options, and peripheral availability from the manufacturer datasheet. Do not infer those parameters from the related MC68HC908QY4 family without checking the complete ordering information. PCB layout must follow the verified 16-pin SOIC footprint and preserve the device-specific power, ground, reset, and programming connections.
This product page combines the verified distributor identity, package information, manufacturer datasheet link, technical parameters, and replacement considerations for engineers evaluating an HC08-based embedded controller. Because detailed timing, electrical, and pin-level data were not supplied in the verified web snippets, those values are intentionally not guessed here.

일반적인 애플리케이션
MC68HLC908QY4CDW 적합 용도: 8 애플리케이션s: Small Appliance Controller, Sensor Interface Module, Simple Relay Control Board, Keypad and Human-Interface Controller, Industrial Embedded Control Module, Programmable Logic Controller, Basic Motor Control Interface, Battery-Powered Embedded Product.
Small Appliance Controller
The MC68HLC908QY4CDW fits a small appliance controller when the product needs an 8-bit CPU, 8 MHz processing, and 4 KB of on-chip Flash for embedded control firmware. The 16-SOIC package provides a compact surface-mount footprint for a controller PCB. Firmware can handle button states, operating modes, timing, and basic actuator logic without requiring a separate program-memory device. Because the supplied data does not specify I/O count, RAM, timers, or voltage range, the designer should confirm those parameters in the NXP datasheet. The principal benefit is integrated nonvolatile storage in a modest embedded package; the main trade-off is limited memory and processing capacity compared with larger 16-bit or 32-bit microcontrollers.
추천
Sensor Interface Module
The MC68HLC908QY4CDW can be used in a sensor-interface module when the system only requires basic digital control and compact firmware. Its 8 MHz 8-bit CPU is suitable for reading sensors, evaluating thresholds, filtering simple signals, and coordinating outputs. The 4 KB Flash memory provides room for program code, while the 16-SOIC package supports automated surface-mount assembly. The device should not be assumed to include a specific ADC, UART, or SPI peripheral because those specifications are not included in the supplied verified snippets. Confirm the complete pinout and peripheral list before selecting external sensors or communication transceivers.
추천
Simple Relay Control Board
The MC68HLC908QY4CDW is a plausible choice for a simple relay-control board where an 8-bit controller must execute state logic, debounce inputs, and operate relays or indicators. The 8 MHz clock supports deterministic loop execution for low- to moderate-complexity control, and 4 KB of Flash keeps application firmware on the device. Designers must verify available I/O pins, output-drive limits, reset behavior, and supply requirements from the datasheet before connecting relay drivers. Relay coils should use appropriate transistor or driver circuitry because a microcontroller pin is not automatically a dedicated relay-driver output.
추천
Keypad and Human-Interface Controller
The MC68HLC908QY4CDW can support a keypad, menu, or simple human-interface controller when the interface consists of discrete inputs and outputs. Its 8-bit architecture is appropriate for debouncing, scanning, state transitions, and display-control logic at modest update rates. The 4 KB Flash capacity is useful for compact firmware, while the 16-SOIC package allows a relatively small PCB footprint. Before implementation, verify the number and electrical characteristics of I/O pins, operating voltage, oscillator requirements, and any timing assumptions. The controller should not be selected for a complex graphical interface unless the available processing and memory requirements are carefully checked.
추천
Industrial Embedded Control Module
The MC68HLC908QY4CDW may be evaluated for an industrial embedded-control module where a low-cost 8-bit processor, compact packaging, and integrated Flash are useful. A controller of this class can monitor discrete sensors, sequence outputs, implement timeout logic, and provide local status indication. The 8 MHz clock and 4 KB Flash are explicitly identified, but the supplied material does not establish industrial temperature qualification, ESD ratings, communication peripherals, or long-term availability. Those attributes must be verified before using the device in a production industrial design. If regulatory, environmental, or extended-temperature requirements exceed the verified data, select a documented qualified MCU instead.
추천
Programmable Logic Controller
The MC68HLC908QY4CDW can be evaluated for a small programmable logic controller or fixed-function sequencer that combines input evaluation and output control. Its 8-bit CPU is adequate for structured ladder-like logic, counters, timers, and state machines when the system does not require extensive communications. The 16-SOIC package helps maintain a compact controller footprint, and 4 KB of Flash permits firmware storage without an external memory device. The design must verify pin availability, timing, watchdog behavior, and input/output electrical limits from the manufacturer datasheet. A production PLC may require a higher-performance MCU for networking, diagnostics, expansion, or safety-related monitoring.
추천
Basic Motor Control Interface
The MC68HLC908QY4CDW may serve as the supervisory controller in a basic motor-control interface when the main power stage is implemented with external MOSFETs or drivers. The 8 MHz 8-bit processor can execute state logic, limit checks, timing sequences, and fault latching for a modest system. Its 4 KB Flash is useful for storing control and diagnostic firmware, while the 16-SOIC package keeps the control section compact. Actual suitability depends on verified PWM outputs, timer resources, ADC availability, and I/O ratings, none of which are confirmed in the supplied snippets. Use external protection and driver circuitry rather than driving motor current directly from the MCU.
추천
Battery-Powered Embedded Product
The MC68HLC908QY4CDW may be investigated for a battery-powered embedded product requiring a small controller and on-chip program memory. The 4 KB Flash can reduce the need for an external program-memory IC, while the 16-SOIC package is compatible with compact surface-mount assemblies. Battery applications require careful review of supply voltage, sleep behavior, active current, wake-up sources, and analog input limits, but those values are not present in the supplied verified data. Confirm the datasheet before selecting battery chemistry, regulator, and power-management components. The controller is best suited to low-to-moderate duty-cycle control functions rather than power-intensive processing.

설계 노트
Do not design the PCB from the distributor title alone. The verified snippets identify an 8 MHz 8-bit device with 4 KB Flash and a 16-SOIC package, but they do not provide the complete pin table. Download the NXP datasheet, map power, ground, reset, oscillator, programming, and I/O pins, and confirm the exact SOIC footprint before fabrication.
Verify the supply-voltage range and absolute maximum limits from the NXP datasheet before connecting external circuitry. The verified data does not provide voltage values, so the regulator and decoupling network cannot be selected responsibly from the search snippets. Confirm whether the device requires specific power sequencing, startup behavior, or programming-mode voltage conditions.
Keep the 16-SOIC footprint orientation tied to the verified pin-1 marking and follow the manufacturer land pattern. Place any required decoupling capacitors close to the device power pins and route programming or reset signals away from noisy switching nodes. Do not infer exposed-pad or thermal-pad requirements; the supplied data identifies a 16-SOIC package but does not provide a thermal-pad detail.
The supplied data does not provide operating temperature, power dissipation, or package thermal-resistance values. Thermal design should therefore wait for the complete datasheet and the final switching frequency and load conditions. Use the surface-mount package's verified copper and land pattern, and validate temperature rise in the assembled prototype rather than estimating from the package name alone.
Related family members should not be treated as equivalents simply because their names end in QY4, QY2, or QY1. Verify memory size, CPU behavior, voltage, reset, oscillator, peripherals, programming, and exact pin assignment for each ordering code. Firmware and PCB changes can turn an apparently related device into a non-drop-in replacement.
규정 준수 정보
