MC9S08SF4MTJ - 40MHz 8-Bit S08 MCU | NXP
部品番号: MC9S08SF4MTJ ✗ 生産終了MC9S08SF4MTJ 概要
An S08 microcontroller is a compact 8-bit embedded-processing platform based on the HCS08 instruction set. It belongs to the broader hierarchy of microcontroller, embedded processor, semiconductor, and electronic-control-system components. Compared with a general-purpose host processor, the MC9S08SF4MTJ combines a defined peripheral set and deterministic control hardware in a small package, making it suitable for dedicated appliances, motor mechanisms, and compact industrial controllers.
The MC9S08SF4 family integrates up to 18 general-purpose input/output pins, six timers, and support for as many as 32 interrupt or reset sources. Its timer resources allow multiple timing, pulse-width modulation, and motor-control tasks to be coordinated by dedicated hardware. The HCS08-compatible instruction set includes the BGND instruction, while the integrated fault-protection features support safe shutdown behavior when configured for fault detection.
The S08 CPU can operate at up to 40 MHz across a 2.7 V to 5.5 V supply range. This frequency headroom provides more instruction throughput than lower-rate 8-bit controllers without requiring a larger processor architecture. The 4 KB Flash configuration is appropriate for compact control firmware that must retain fast on-chip program storage while minimizing package size and system complexity. An internal 10-bit ADC feature is identified for this device family, although detailed converter ranges and timing require consultation of the manufacturer datasheet.
Typical applications include small brushless DC motor controllers, simple motor mechanisms, fan and pump controllers, actuator interfaces, and embedded industrial control products. Multiple timers and GPIO resources allow a controller to monitor inputs, generate motor-drive timing signals, handle fault conditions, and coordinate external sensors. The wide supply range also accommodates both 3.3 V and 5 V system architectures where their electrical requirements are otherwise compatible.
Designers should preserve the electrical and decoupling requirements in the manufacturer datasheet and place input and output bypass capacitors close to the supply pins. Firmware must reserve suitable GPIO pins for motor-control outputs, fault inputs, and shutdown signaling. Because the MCU can run as fast as 40 MHz, clock configuration, reset behavior, and unused-pin handling should be validated as a complete hardware-software design rather than treated as isolated firmware tasks.
This product overview combines the key electrical limits, memory capacity, control resources, lifecycle status, and application constraints of the MC9S08SF4MTJ. It also identifies package and sourcing considerations for engineers evaluating the device for new compact motor-control platforms, legacy product maintenance, and board-level redesign work.

主な用途
MC9S08SF4MTJ の用途: 6 件s: Compact Brushless DC Motor Controller, Small Fan and Pump Controller, Actuator and Valve Position Controller, Industrial Sensor Interface Hub, Consumer Appliance Control Module, Robust Industrial Control Node.
Compact Brushless DC Motor Controller
The MC9S08SF4MTJ fits compact brushless DC motor controllers because its S08 core reaches 40 MHz while six timer modules provide dedicated timing for commutation, pulse-width modulation, and speed-related functions. Up to 18 GPIO pins leave useful capacity for position sensors, direction controls, fault inputs, and status outputs. The 4 KB Flash footprint supports compact motor logic, while the 2.7 V to 5.5 V range accommodates common low-voltage architectures. Designers should assign motor-direction and fault functions carefully and validate the external driver, current sensing, and shutdown path.
おすすめ
Small Fan and Pump Controller
The MC9S08SF4MTJ is suitable for small fan and pump controllers where multiple timing channels must coordinate speed commands, startup behavior, and fault monitoring. Its six timers can divide into PWM, input capture, or periodic-control functions, while the 40 MHz CPU leaves processing headroom for closed-loop control and diagnostics. The MCU can operate from 3.3 V or 5 V supplies within the specified 2.7 V to 5.5 V range. The external MOSFET or driver stage must be selected for the load current, and supply transients from motor commutation should be isolated from the MCU rail.
おすすめ
Actuator and Valve Position Controller
The MC9S08SF4MTJ can serve as the central controller in compact actuator, valve, and positioning mechanisms that require deterministic pulse timing and several discrete I/O points. The 40 MHz S08 processor supports responsive control logic, the six timers support time-based sequencing, and the up-to-18-pin GPIO allocation can serve limit switches, encoders, solenoid drivers, and diagnostic signals. Its -40 °C to +125 °C rating supports extended environments when the complete mechanism permits it. Firmware should include defined safe states for sensor failure and actuator overtravel.
おすすめ
Industrial Sensor Interface Hub
The MC9S08SF4MTJ works as a compact sensor-interface hub for industrial equipment that must combine digital inputs, timing functions, and controlled outputs in one controller. Its 10-bit ADC feature provides a basic conversion path where appropriate, while up to 18 GPIO pins can accommodate switches, alarm inputs, status LEDs, and communication links. At 40 MHz, the S08 core can service multiple periodic tasks without moving to a higher-power processor. Analog front-end conditioning, input protection, and grounding remain necessary because a general-purpose MCU ADC does not replace precision sensor circuitry.
おすすめ
Consumer Appliance Control Module
The MC9S08SF4MTJ can implement the timing and discrete-control portion of a compact appliance such as a small motor-driven mechanism, pump system, or actuator assembly. Its 4 KB Flash capacity is appropriate for focused firmware, and the 20-pin TSSOP package reduces board area when compared with larger controller packages. Six timers allow multiple motor, valve, or indicator timing functions to operate concurrently. The MCU should be paired with protected driver circuitry because inductive loads can introduce supply noise and ground bounce beyond the logic device’s own protection ratings.
おすすめ
Robust Industrial Control Node
The MC9S08SF4MTJ is appropriate for a compact industrial control node that requires extended-temperature operation, precise timer-based control, and a modest amount of embedded firmware. The -40 °C to +125 °C specification covers demanding ambient conditions, while the 40 MHz CPU and six timers support real-time sampling, PWM generation, and periodic housekeeping. Its 4 KB Flash keeps the program footprint focused, and the 20-pin TSSOP is practical for dense control boards. System qualification must include power-transient immunity, thermal-rise analysis, and safe behavior after reset or sensor failure.

設計ノート
Use the 20-pin TSSOP-20 land pattern specified by the package drawing and place the input and output bypass capacitors close to their respective supply pins. Keep motor-driver power currents away from the MCU ground return; route high-di/dt switch-node copper separately and provide a stable ground reference for the S08. Confirm pin multiplexing, programming signals, reset, and clock connections against the exact datasheet pin-description table before releasing the layout.
Design the 2.7 V to 5.5 V supply path for both steady-state operation and motor-induced transients. Decouple the MCU rail locally, select a regulator with adequate transient response, and avoid routing actuator current through narrow supply traces. Validate the maximum CPU frequency at the lowest intended supply voltage and include brownout or undervoltage behavior appropriate to the mechanical system so the controller enters a defined safe state instead of continuing with invalid logic states.
Do not assume that another S08 MCU with a similar package is software- or pin-compatible. The MC9S08SF4MTJ has a defined Flash size, memory map, interrupt organization, timer layout, and multiplexing scheme that must be matched before substitution. When revising an existing design, preserve the device family and ordering suffix until a manufacturer comparison confirms otherwise; changing only the speed grade or family code can alter peripheral availability even when the land pattern remains unchanged.
The MCU's -40 °C to +125 °C rating does not eliminate thermal design requirements in a motor-control enclosure. Estimate heat rise from the local regulator, external driver, and MCU rather than from the MCU alone, and account for copper area, airflow, and adjacent heat sources. Use the package thermal information for the intended board construction, and perform temperature testing at the highest expected ambient temperature with the motor and power stage operating at their worst-case duty cycle.
