MC9S08QE8CFM - 8-Bit 20MHz MCU, 8KB Flash | NXP Semiconductors
部品番号: MC9S08QE8CFM ✗ 生産終了MC9S08QE8CFM 概要
A microcontroller is a programmable semiconductor that integrates a CPU core, memory, peripheral interfaces, and input/output ports on one integrated circuit. MC9S08QE8CFM belongs to the HCS08/S08 family, combining an 8-bit embedded CPU with serial communications and analog measurement. Its QFN surface-mount package supports compact PCB layouts, while the exposed-pad construction provides a practical thermal path when the device operates continuously.
Key features include 8 KB of flash for program storage, 512 bytes of RAM, a 10-bit ADC, and communication interfaces including IIC, SCI, and SPI. A 1.8 V to 3.6 V operating range allows operation from low-voltage 3.3 V systems and compatible mixed-voltage industrial equipment. The 20 MHz clock specification supports responsive control tasks without requiring a larger external processor.
The S08 architecture is intended for embedded applications where deterministic peripheral access, compact code, and low system complexity are more important than high-bandwidth processing. Serial interfaces allow the MCU to connect sensors, transceivers, displays, and external nonvolatile memory. The ADC supports cost-sensitive analog sensing, while GPIO resources allow direct control of switches, indicators, actuators, and digital communication lines.
Typical uses include automotive body-control modules, industrial sensors, building controls, appliance controllers, battery-powered instruments, and compact communication equipment. In each case, the MCU consolidates control logic, analog measurement, and external communication into a small surface-mount footprint. Its 8 KB flash capacity is best matched to focused applications with compact firmware rather than extensive graphical interfaces or large protocol stacks.
Design the PCB with a short ground return and a solid thermal path beneath the exposed pad. Confirm that the selected programming tools, clock configuration, interface levels, and firmware memory requirements match the device. Because NXP marks this exact orderable part as end of life, long-life programs should verify availability and planned migration before committing to new production designs.
This page organizes the manufacturer lifecycle information, package characteristics, interface capabilities, application fit, and engineering trade-offs. It also distinguishes exact drop-in alternatives from merely similar 8-bit microcontrollers, helping engineers avoid assumptions based only on memory size, clock rate, or pin count.

主な用途
MC9S08QE8CFM の用途: 6 件s: Automotive Body-Control Module, Industrial Sensor Interface, Building and HVAC Control, Battery-Powered Instrument, Serial Communication Gateway, Appliance and Equipment Controller.
Automotive Body-Control Module
The MC9S08QE8CFM fits compact body-control modules that require digital input handling, serial communication, and limited analog measurement. Its 8-bit S08 core, 20 MHz maximum clock, 28 GPIO ports, and 1.8 V to 3.6 V operating range support economical low-voltage control platforms. The 10-bit ADC can monitor simple analog conditions, while IIC, SCI, and SPI provide links to sensors and external controllers. The 32-pin QFN package also reduces board area compared with larger leaded packages. For an automotive program, verify qualification, traceability, software maintenance, and lifecycle support before production release.
おすすめ
Industrial Sensor Interface
The MC9S08QE8CFM is suitable for industrial sensor interfaces that combine analog measurement with a local control loop. The 10-bit ADC supports basic sensing, while IIC and SPI can connect sensors, analog-to-digital converters, or nonvolatile storage. Its 8 KB flash accommodates focused acquisition and configuration firmware, and the 512-byte RAM supports sample buffers and communication state. Operating from 1.8 V to 3.6 V permits integration with low-voltage sensor systems, while the compact 32-pin QFN preserves board space. Apply suitable filtering and grounding techniques at analog inputs to prevent converter noise from affecting measurements.
おすすめ
Building and HVAC Control
The MC9S08QE8CFM can serve as the local controller in a room thermostat, actuator controller, or compact building-control node. GPIO outputs can drive relays, indicators, and digital actuators, while the ADC can monitor temperature, potentiometer, or occupancy-sensor signals. IIC and SPI support expandable I/O and local data storage, and SCI enables a supervisory serial link. The 20 MHz S08 core provides sufficient performance for deterministic monitoring and simple control algorithms. The QFN package is useful in space-constrained wall controllers, but the exposed pad and supply circuitry require careful PCB layout for reliable thermal and EMC behavior.
おすすめ
Battery-Powered Instrument
The MC9S08QE8CFM supports low-voltage, compact instruments where display updates, sensor acquisition, and configuration storage must share one controller. The 1.8 V minimum supply voltage and 3.6 V maximum suit low-energy rails, while the 8 KB flash stores a focused firmware image and the 512-byte RAM supports working state. IIC can connect a compact display or sensor, while SCI can support an external host. Because the S08 family is designed for cost-sensitive embedded control, the device is well matched to simple meters and handheld diagnostic products. Low-power behavior should be confirmed in the manufacturer documentation for every active peripheral and communication mode.
おすすめ
Serial Communication Gateway
The MC9S08QE8CFM can act as a compact protocol gateway or embedded communications controller when the design needs SCI, SPI, and IIC in one device. SCI provides a straightforward host interface, SPI supports faster local peripherals, and IIC addresses low-speed sensors or EEPROMs. Its 8 KB flash and 512-byte RAM are appropriate for framing, buffering, status reporting, and configuration rather than large protocol stacks. The 32-pin QFN package helps minimize board area in distributed equipment. Verify signal levels and pin multiplexing for each peripheral, and provide solid grounding and controlled clock routing to maintain communication reliability in electrically noisy environments.
おすすめ
Appliance and Equipment Controller
The MC9S08QE8CFM is appropriate for appliance controllers, test fixtures, and compact equipment-control boards that need deterministic logic without a high-performance processor. The 20 MHz S08 core handles control sequencing, button inputs, status indicators, and sensor processing, while 28 GPIO ports expose broad digital connectivity. IIC, SCI, SPI, and the 10-bit ADC reduce the need for separate interface components. An 8 KB flash footprint is adequate for focused state-machine firmware, and the 32-pin QFN package reduces board footprint. Confirm the industrial temperature requirement and end-of-life procurement plan before using the device in new long-running production equipment.

設計ノート
Route the 32-pin QFN lands and exposed-pad connection exactly as shown in the manufacturer package drawing. Keep the exposed-pad connection electrically consistent with the power and ground recommendations in the datasheet. Place input, output, and decoupling capacitors close to their associated pins, and use a short ground return from the exposed pad. Because this package has no protruding leads, assembly capability and land-pattern tolerances should be checked before releasing the PCB.
Design the supply network for the stated 1.8 V to 3.6 V operating range and the selected peripheral configuration. Place local bypass capacitance at the supply pins, maintain a low-impedance ground plane, and account for startup current when sizing the regulator and trace widths. Confirm that the clock and communication settings do not exceed any current or voltage restriction listed for the exact device configuration.
Do not treat an 8 KB-flash, 8-bit MCU with the same pin count as a drop-in replacement. The ATMEGA88A-MUR comparison is functionally similar but does not establish identical package dimensions, exposed-pad use, peripheral mapping, or software compatibility. Review the pin table, reset behavior, clock setup, interrupt vectors, and driver code before any substitution. Also validate long-term supply because the exact NXP part is marked end of life.
