MC908QC8CDZE 概要
A microcontroller is a semiconductor device that integrates a CPU core, program memory, data memory, and peripherals into one package. The MC908QC8CDZE uses the HC08 architecture, described in the supplied datasheet search result as an enhanced M68HC08 central processing unit within a CISC, Von Neumann microcontroller family. This positioning makes it suitable for compact control, monitoring, and automation products where a deterministic 8-bit controller and established software toolchain are more appropriate than a higher-complexity processor.
The principal verified specifications are the 8-bit data-bus width, 8 MHz maximum clock frequency, 8 KB flash configuration, HC08 core, and 28-SOIC package. The flash format is listed as 8K x 8, indicating an 8,096-bit-wide organized flash memory representation in the distributor description. Other electrical details, including RAM capacity, I/O count, voltage range, timer resources, and communication peripherals, are not present in the supplied verified data and are therefore not inferred here.
Typical design uses include small motor-control modules, appliance controllers, industrial interface boards, remote sensor nodes, and legacy embedded products that already use the HC08 family. A replacement should be selected only after checking the complete manufacturer datasheet, especially pin assignments, electrical limits, clock requirements, memory organization, and software support. The 28-SOIC footprint is the mechanically confirmed package class in the verified listing, but a genuine drop-in alternative requires exact pin and functional equivalence, not merely a similar flash size.
This page consolidates verified distributor and datasheet-search references for MC908QC8CDZE, highlights the 8 MHz HC08 architecture and 8 KB flash configuration, and separates confirmed data from parameters requiring engineering review. Pricing, lifecycle status, pin-level details, and alternative-device specifications should be confirmed against current manufacturer or authorized-distributor documentation before design release.

主な用途
MC908QC8CDZE の用途: 6 件s: Legacy Appliance Controller, Small Motor-Control Module, Industrial Interface Board, Remote Sensor Node, Remote Control Product, Compact Automation Controller.
Legacy Appliance Controller
The MC908QC8CDZE fits compact appliance-control boards that use an established HC08 codebase. Its confirmed 8-bit core, 8 MHz maximum clock frequency, and 8 KB flash provide a straightforward control platform for mode selection, button handling, actuator sequencing, and status indication. The device is placed as the main embedded controller, with firmware executing from flash and external circuitry handling loads and user inputs. Because voltage, RAM, I/O, and timer details are not present in the supplied verified data, the final design must confirm those resources from the manufacturer datasheet. This is especially suitable for legacy products rather than new systems requiring extensive connectivity or large memory.
おすすめ
Small Motor-Control Module
MC908QC8CDZE can serve as the sequencing and control MCU in a small motor-control module where a compact 28-SOIC device and 8-bit processing are sufficient. Firmware can manage start commands, direction or speed states, limit inputs, and protection flags while external drivers interface to the motor. The confirmed 8 MHz clock gives the software a defined processor-performance basis, and the 8 KB flash limits program size, so code should be compact and table-driven. Timer resources, pin assignments, and electrical limits are not verified in the supplied data and must be checked before assigning motor-control functions.
おすすめ
Industrial Interface Board
The MC908QC8CDZE is appropriate for a small industrial interface or condition-monitoring board that translates discrete inputs into a controlled output sequence. Its 8-bit architecture and 8 MHz clock are suitable for straightforward polling and state-machine firmware, while 8 KB flash supports compact protocol and configuration logic. The board would typically connect the MCU to sensors, optocouplers, relays, and status indicators, with the exact peripheral requirements selected only after checking the verified datasheet. Industrial qualification and environmental limits are unknown from the supplied results, so this application requires additional component and enclosure validation.
おすすめ
Remote Sensor Node
MC908QC8CDZE can be used in a low-power remote sensor node when the node needs local control, periodic sampling, and a compact legacy-compatible platform. The 8-bit HC08 core handles sensor state machines and threshold decisions, while external circuitry supplies conditioning and communication. The 8 MHz clock provides a clear processing ceiling, and the 8 KB flash budget favors small firmware images and fixed configuration data. Because current consumption, RAM, timer availability, and communication peripherals are not confirmed in the supplied data, battery life and radio integration cannot be finalized without the manufacturer documentation.
おすすめ
Remote Control Product
The MC908QC8CDZE is a plausible candidate for a compact remote-control or keypad product built around an existing HC08 ecosystem. The 8-bit processor can scan inputs, debounce switches, maintain operating state, and drive display or indicator outputs. Its 8 KB flash provides storage for a small command table and product-specific behavior, while the 28-SOIC package supports conventional PCB assembly. The supplied evidence does not confirm the number or electrical type of I/O pins, so the complete pinout and external driver requirements must be verified before schematic release.
おすすめ
Compact Automation Controller
MC908QC8CDZE can support compact automation functions such as relay sequencing, timeout handling, alarm logic, and local operator control. The 8-bit HC08 architecture is appropriate when the system is designed around deterministic state machines rather than high-bandwidth computation. The MCU would be placed beside input conditioning, driver transistors, and status circuitry, with firmware occupying the confirmed 8 KB flash budget. The supplied data does not verify communication interfaces, supply range, or environmental ratings, so engineers must review the full datasheet and confirm the controller's production qualification before using it in safety-related or harsh industrial equipment.

設計ノート
Do not finalize the PCB layout from the distributor package label alone. Obtain the exact 28-SOIC drawing and complete manufacturer pin assignment, then verify pin 1 orientation, exposed versus non-exposed thermal-pad details, and every power and ground connection before routing. The verified sources identify the package as 28-SOIC but do not provide a reliable numbered pinout, so schematic and footprint review must use the authoritative datasheet.
Confirm the supported supply range, decoupling requirements, reset thresholds, and input tolerance from the manufacturer datasheet before adding external circuitry. The verified data confirms an 8 MHz HC08 and 8 KB flash but gives no voltage or current limits. Apply the manufacturer's recommended power-decoupling network and confirm that regulator tolerance, startup behavior, and brownout behavior are adequate for the board's supply as of 2026-10-21.
A shared HC08 family name does not establish drop-in compatibility. The target is confirmed as an 8-bit, 8 MHz, 8 KB-flash HC08 in 28-SOIC, but candidate devices may differ in memory, pin assignment, clock options, peripherals, and electrical ratings. Compare every numbered pin and memory function against the manufacturer documents before approving a substitution or reusing an existing footprint.
コンプライアンス情報
The supplied search results do not include a complete, exact-MPN compliance declaration. A generic RoHS label appears in one Freescale-related snippet, but it is insufficient to classify this NXP ordering code. Confirm RoHS, REACH, lead-free, halogen-free, conflict-minerals, and automotive qualification with NXP or an authorized distributor.
