MC908QY4CDWER-FR 8-Bit 8MHz 4KB Flash MCU | NXP
MPN： MC908QY4CDWER-FR ✓ 啟用中MC908QY4CDWER-FR 概覽
An HC08 microcontroller is an embedded processor within the broader 8-bit microcontroller category. It combines a CPU08 core, on-chip program memory, peripheral modules, I/O ports, and interrupt-driven control functions on one device. This integration allows a design to replace discrete logic and reduces board area compared with larger general-purpose microcontrollers. The MCU is particularly useful where deterministic control, modest processing demand, and low system complexity are more important than high bandwidth or extensive memory.
The key verified specifications are an 8 MHz maximum operating frequency, 4 KB flash storage, 8-bit CPU architecture, and a 16-pin SOIC package. A related NXP product-page result identifies the MC908QY4CDWE as an HC08Q-family device with a 4 KB flash option. The verified distributor data also describes the target as a 4K-flash HC08 MCU with ADC-related product labeling, although detailed ADC conversion parameters, RAM capacity, timer specifications, and electrical limits are not included in the supplied source data and are therefore not inferred here.
The MC908QY4CDWER-FR can be used in compact consumer controllers, simple instrumentation, keypad interfaces, low-speed communication modules, relay-control boards, and embedded automation products. Its small package helps reduce PCB footprint, while flash memory supports self-contained firmware. The 8 MHz clock is suitable for basic sequencing, state-machine control, input scanning, and peripheral coordination rather than demanding signal-processing workloads.
For a new design, engineers should verify the exact pinout, ADC characteristics, memory map, reset behavior, and operating electrical limits against the manufacturer datasheet before layout or firmware commitment. Because the supplied data includes conflicting distributor descriptions for related package and speed fields, this page preserves the directly verified 8 MHz, 4 KB flash, 8-bit, and 16-SOIC values for MC908QY4CDWER-FR.
This page combines verified distributor and manufacturer-product information with package-focused engineering guidance, availability references, and cautious replacement analysis. It avoids treating similar HC08 variants as drop-in alternatives unless the supplied cross-reference evidence establishes the required pin and parametric compatibility.

典型應用
MC908QY4CDWER-FR 適用於 6 應用s: Compact Consumer Appliance Controller, Keypad and User Interface Control, Basic Sensor Signal Conditioning, Small Motor and Relay Control, Low-Cost Instrumentation Interface, Embedded Automation Node.
Compact Consumer Appliance Controller
The MC908QY4CDWER-FR fits compact appliance controllers that coordinate buttons, indicators, relays, and small motors while keeping the board area low. Its verified 8 MHz 8-bit CPU is appropriate for deterministic state-machine control, and 4 KB flash provides space for a self-contained control program. The 16-pin SOIC package also supports conventional surface-mount assembly. Designers should verify ADC, timer, and pin details from the exact datasheet because those specifications are not fully exposed in the supplied data.
推薦
Keypad and User Interface Control
Use MC908QY4CDWER-FR in a compact keypad or simple user-interface controller when the device must scan inputs, debounce contacts, update indicators, and manage a small state machine. The verified 8-bit architecture and 8 MHz clock are aligned with basic input polling and control logic, while 4 KB flash can hold firmware without external program memory. Exact I/O mapping and timing margins must be confirmed because the supplied information does not provide a complete pinout.
推薦
Basic Sensor Signal Conditioning
MC908QY4CDWER-FR can serve as a basic embedded controller for slow-changing sensor measurements when the system requires local logic, thresholding, and actuator signaling. Its ADC-related product designation makes the part relevant to measurement-oriented designs, but no ADC resolution, sampling rate, input range, or accuracy is stated in the verified data. Use it only after confirming the ADC electrical characteristics and pin assignment in the manufacturer datasheet.
推薦
Small Motor and Relay Control
The 8-bit HC08/S08 MC908QY4CDWER-FR is suitable for modest relay or small-motor sequencing where the controller mainly handles commands, interlocks, timing, and status feedback. Its 8 MHz clock is more than adequate for ordinary control loops, and the 4 KB flash footprint supports a compact embedded program. The available data does not specify timer resolution, output drive current, or protection requirements, so power transistors, flyback paths, and timing must be designed separately.
推薦
Low-Cost Instrumentation Interface
For basic instrumentation, MC908QY4CDWER-FR can coordinate sensor acquisition, local display or indicator updates, button input, and alarm thresholds. The 4 KB flash memory and 8 MHz 8-bit CPU support small embedded applications without a high-performance processor, while the 16-pin SOIC package keeps the design compact. The supplied sources do not verify the complete ADC, RAM, timing, or communication peripheral set, so instrumentation requirements must be checked against the official datasheet.
推薦
Embedded Automation Node
MC908QY4CDWER-FR can be used in a small automation node for local sequencing, discrete I/O handling, and controlled actuator outputs. Its CISC/Von Neumann HC08 architecture is appropriate for straightforward embedded control, and the 16-pin package supports compact boards when external drivers are provided. For field deployments involving long wiring, electrical transients, or extended temperature exposure, verify transient immunity and environmental ratings because those values are not present in the supplied data.

主要差異化特點

- Same-package sourcing family (對比MC908QY4CDTER)
設計說明
Use the exact 16-pin SOIC land pattern from the official package drawing and verify pin numbering against the MC908QY4CDWER-FR datasheet before routing. The supplied sources establish the package family but do not provide the complete signal map, so do not assign power, programming, reset, ADC, or I/O functions from a generic HC08 footprint. Confirm pad dimensions, pin-one orientation, and exposed thermal-pad requirements; no exposed pad is identified in the verified data.
The verified comparison data lists a 4.5 V to 5.5 V supply range for the related MC908QY4CDWER listing, but the exact FR ordering document should be checked before power-system design. Provide stable supply and ground connections within the manufacturer’s limits, and place local bypassing where the datasheet requires it. Do not infer absolute maximum voltage, ADC reference limits, or output-drive current from distributor snippets.
Do not substitute a related HC08 MPN solely because it has a 16-pin SOIC package. MC908QY4ACDWE, MC908QB8CDWE, MC908QB4CDWE, MC908QY4CDTER, and MCHC908QY4MDWE appear in cross-reference search results, but the supplied evidence does not establish identical pin mapping, memory, timing, peripherals, or voltage behavior. Check the manufacturer datasheets and qualify any alternate in the final firmware and hardware test plan.
For a mixed analog or digital design, keep the MCU supply return short and route potentially noisy switching or motor-drive paths away from ADC and control inputs. Because the supplied data does not specify ADC input impedance, sampling time, reference-voltage limits, or recommended layout, treat these values as missing and use the official application guidance once obtained. Add test points for reset, programming, supply, and critical I/O when space permits.
