MC9S08AC16MFJE Übersicht
An 8-bit microcontroller is a programmable semiconductor containing a CPU core, memory, I/O ports, timers, communication interfaces, and other peripherals on one integrated circuit. The S08 family belongs to the HCS08 lineage of 8-bit MCUs and is commonly used for appliance controls, industrial modules, automotive functions, and small control boards where an efficient core and dedicated peripherals are more useful than a high-complexity processor.
The verified product information identifies a 40 MHz S08 core, 16 KB Flash memory, 4 KB RAM according to Mouser, 2.7 V to 5.5 V supply voltage, I2C, SCI, SPI, PWM, watchdog, low-voltage detection, and power-on reset. The package information is consistently identified by distributor listings as 32-LQFP, although one secondary result contains conflicting package metadata; the manufacturer and distributor package designation should be checked against the purchased ordering code.
The MC9S08AC16 family is positioned for cost-sensitive automotive and industrial control applications, as described on the NXP product page. Its Flash memory supports in-system firmware storage and updates, while serial interfaces enable connection to sensors, actuators, external memory, and service equipment. The 2.7 V to 5.5 V operating range accommodates regulated 3.3 V and 5 V systems when the individual peripheral and electrical limits are satisfied.
For new designs, engineers should confirm the exact pin assignments, multiplexing options, memory organization, clock configuration, electrical limits, and package drawing from the official NXP or Freescale datasheet before layout release. The MFJE suffix and 32-LQFP footprint should be treated as essential ordering and PCB-matching identifiers.
A typical implementation places the MCU beside a regulated supply, decoupling capacitors, sensor interfaces, and a communication transceiver or connector. Firmware configuration should verify oscillator start-up, watchdog behavior, interrupt priorities, unused-pin handling, and peripheral pin multiplexing before production.

Typische Anwendungen
MC9S08AC16MFJE ist geeignet für 6 Anwendungs: Automotive Control Module, Industrial Sensor Interface, Appliance and Household Control, Motor and PWM Actuator Control, Serial Communication Gateway, Low-Cost Embedded Control Platform.
Automotive Control Module
The MC9S08AC16MFJE fits compact vehicle-control modules where an 8-bit CPU, Flash program memory, serial interfaces, and a 32-LQFP package reduce board complexity. Its listed I2C, SCI, SPI, PWM, watchdog, low-voltage detection, and power-on reset functions support sensing, actuator control, diagnostic communication, and orderly recovery. The automotive positioning should be confirmed against the exact temperature grade and qualification documents before production release.
Empfohlen
Industrial Sensor Interface
The MC9S08AC16MFJE can serve as the controller for a small industrial sensing board using its 40 MHz S08 core, 16 KB Flash, I2C, SCI, and SPI connectivity. The 2.7 V to 5.5 V supply range is useful for regulated 3.3 V or 5 V designs, while PWM and watchdog functions support timing and fault recovery. The design must confirm pin multiplexing, peripheral electrical limits, and grounding in the official datasheet.
Empfohlen
Appliance and Household Control
The MC9S08AC16MFJE is appropriate for appliance controllers that combine local decision-making with serial sensor or actuator connections. Its Flash memory stores firmware, and the S08 core executes control logic without requiring a larger processor when the task set is modest. The verified 32-LQFP package supports compact board layouts, but exact pin functions, reset timing, and peripheral limits must be confirmed before schematic capture.
Empfohlen
Motor and PWM Actuator Control
The MC9S08AC16MFJE can coordinate PWM-based actuator outputs in small motor-control and valve-control subsystems. Its listed PWM feature, watchdog timer, low-voltage detection, and power-on reset support deterministic control-loop execution and system monitoring. The MCU should be paired with the required driver stage, protection circuitry, and decoupling; verify the exact PWM channels, timing, and I/O ratings in the datasheet.
Empfohlen
Serial Communication Gateway
The MC9S08AC16MFJE is suitable for a compact protocol-conversion or service-interface board because it includes SCI and SPI connectivity alongside I2C. Firmware can coordinate between a host serial link and local sensors or actuators while using the watchdog and reset functions for reliability. Communication timing, pin multiplexing, and logic-level compatibility should be verified in the official datasheet and validated on prototype hardware.
Empfohlen
Low-Cost Embedded Control Platform
The MC9S08AC16MFJE provides a straightforward 8-bit control platform with 16 KB Flash, 4K x 8 RAM, and a 40 MHz clock for compact embedded products. Its 2.7 V to 5.5 V supply range allows integration with common regulated rails, while the small 32-LQFP package supports space-constrained boards. Firmware developers should budget memory, test startup and watchdog behavior, and confirm unused-pin requirements before production.

Wichtigste Unterscheidungsmerkmale
- Integrated 8-bit control platform (vs. General-purpose discrete controller approach)
- Compact 32-LQFP integration (vs. Larger-package MC9S08 implementations)
- Broad common-rail supply range (vs. Fixed 3.3 V or fixed 5 V controller designs)
Designhinweise
Design the supply network around the verified 2.7 V to 5.5 V operating range and place the required decoupling capacitors close to the device power pins according to the official datasheet. Confirm absolute maximum ratings, external component voltage ratings, startup current, and brownout behavior before selecting regulators. The low-voltage detection and power-on reset features should be included in the system power-sequencing plan.
Use the official 32-LQFP land pattern and verify pin 1 orientation, courtyard clearance, solder-mask design, and thermal-via strategy against the manufacturer package drawing. The supplied search results contain conflicting QFN metadata from one secondary source, so do not release a footprint until the NXP package information for the complete ordering code is checked. Keep switching or high-current traces away from sensitive sensor and communication routes.
Do not infer pin assignments from another MC9S08AC16 package variant. Confirm pin multiplexing for I2C, SCI, SPI, PWM, reset, clock, and debug functions in the datasheet. Also validate oscillator configuration, watchdog behavior, unused-pin treatment, and communication logic levels. The family name alone does not prove pin-to-pin compatibility.
Compliance-Informationen
A secondary technical listing describes the part as RoHS compliant. The supplied data does not confirm REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status. Automotive positioning and temperature-grade wording are present, but qualification evidence was not supplied.
