MC9S08SH4MPJ Übersicht
An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, RAM, non-volatile program memory, and peripherals such as timers, ADC, and communication blocks. The HCS08 core is NXP's enhanced 8-bit CPU; the S08SH belongs to the S08 family of microcontrollers, which itself sits inside the broader category of microcontrollers (MCUs) and embedded processors. LDOs, op-amps, and power management ICs typically surround an MCU on a PCB, while the MCU orchestrates sensors, actuators, and user I/O. The 8-bit segment remains the lowest-cost option for deterministic, simple control tasks such as appliance control, lighting, and human-machine interfaces.
Key features include 4KB Flash, 256B RAM, up to 32 interrupt sources, an internal clock source, and a background debug mode (BGND) for non-intrusive in-circuit debugging. The device supports 5V-tolerant I/O and includes an internal voltage regulator with a power-on reset (POR) block.
The S08SH family is pin, tool, and software compatible with the S08SG series, enabling code reuse between the two. The ADC's 2.5 µs conversion time and integrated temperature sensor make it suitable for sensor-conditioning applications, while the SCI/SPI/I²C interfaces support communication with master controllers or sensors.
Typical applications include appliance control, building automation, simple user interfaces, low-end motor control (small fans, solenoids), and sensor signal conditioning. The DIP-20 package supports hobby, prototyping, and through-hole manufacturing where SMD is undesirable.
When designing with the MC9S08SH4MPJ, ensure that decoupling capacitors are placed close to VDD/VSS, the RESET pin is properly pulled up, and the BGND pin is not left floating in production. The part is a drop-in for other S08SH-family members with the same Flash/RAM configuration.

Typische Anwendungen
MC9S08SH4MPJ ist geeignet für 6 Anwendungs: Appliance Control Board, Hobby and Educational MCU Boards, Sensor Signal Conditioning Node, LED Lighting Controller, Automotive Auxiliary Module, Simple Human-Machine Interface (HMI).
Appliance Control Board
The MC9S08SH4MPJ fits low-cost appliance controls (washing machines, dishwashers, microwaves) because its 40 MHz HCS08 core executes simple state machines and PWM logic deterministically. The 12-channel 10-bit ADC at 2.5 us conversion reads thermistors, current shunts, and user knob inputs, while the SCI/SPI/I²C interfaces communicate with display modules or Wi-Fi/BLE modules. The 4KB Flash holds the full firmware including fault-handling routines, and the wide 2.7-5.5V supply range lets it run from rectified mains directly with a small linear regulator. NXP's S08SH family is tool-compatible with the same CodeWarrior toolchain as the higher-end S08 parts.
Empfohlen
Hobby and Educational MCU Boards
The MC9S08SH4MPJ's 20-pin PDIP through-hole package suits breadboard prototyping and educational kits where students learn 8-bit assembly or C programming. The DIP-20 form factor drops into standard 0.1-inch breadboards and cable management protocols teach students how to wire I/O pins to LEDs, buttons, and simple sensors. The 4KB Flash holds beginner projects from LED blinkers to line-following robots, and the BGND background-debug interface allows in-circuit debugging without expensive tools. NXP's S08SH family shares its toolchain with the S08SG series, so the same IDE supports multiple project families.
Empfohlen
Sensor Signal Conditioning Node
The MC9S08SH4MPJ works as a small sensor-conditioning node where multiple analog inputs (temperature, humidity, light) are read and transmitted over a digital interface to a master controller. The 12-channel 10-bit ADC with 2.5 us conversion samples up to a dozen sensors sequentially, while the integrated temperature sensor calibrates other sensors against the die temperature. The SCI/SPI/I²C interfaces forward processed data to a master PLC, Raspberry Pi, or wireless MCU module. The automotive -40C to +125C temperature grade lets the node survive outdoor and under-hood environments.
Empfohlen
LED Lighting Controller
The MC9S08SH4MPJ drives small LED lighting controllers and dimmers because its 40 MHz bus and PWM-capable timers generate high-resolution brightness ramps without flicker. The 12-channel ADC reads ambient light sensors and potentiometer inputs, while the SCI interface connects to DMX512 or 0-10V dimming networks. The 2.7-5.5V supply matches constant-current LED driver rails directly. NXP's S08SH family supports low-power wait/stop instructions so standby power stays below 1 mA when the lights are off.
Empfohlen
Automotive Auxiliary Module
The MC9S08SH4MPJ's automotive temperature grade (-40C to +125C) and 5V supply tolerance suit auxiliary vehicle modules such as window controllers, mirror adjusters, seat-position sensors. The 12-channel ADC reads position-feedback potentiometers, current shunts, and temperature sensors, while the SCI/SPI interfaces communicate with the central body controller. The S08SH family's pin and tool compatibility with the S08SG series enables code reuse across vehicle platforms. Note: this part is End-of-Life and new automotive designs should migrate to Kinetis E-series (MKE02Z).
Empfohlen
Simple Human-Machine Interface (HMI)
The MC9S08SH4MPJ drives simple HMIs such as membrane-key panels, 7-segment displays, and small character LCDs because its 40 MHz core runs refresh routines and debounce logic efficiently. The SCI interface connects to a host PLC for status updates, while the GPIO pins scan 4x4 keypads and drive LED indicators. The 4KB Flash holds the full HMI state machine and the -40C to +125C temperature grade tolerates industrial cabinet environments.

Wichtigste Unterscheidungsmerkmale
- Same-family 20-pin PDIP drop-in alternative with identical die (vs. MC9S08SH4MWJ)
- Double the memory at a different footprint (vs. MC9S08SH8CTGR)
- Lower-cost, lower-speed family alternative (vs. MC9S08QD4CSC)
Designhinweise
Estimated: at 40 MHz and 5V supply, the MC9S08SH4MPJ draws roughly 15-20 mA active current. Place a 100 nF decoupling capacitor within 5 mm of the VDD pin and a 10 uF bulk capacitor on the supply rail. The internal voltage regulator generates the core supply from VDD, so external regulation is not required. For low-power stop mode, current drops to single-digit µA but the BGND pin must be held high to prevent accidental debug entry.
Keep ADC analog traces (PTA0-7) short and away from PWM or switching signals to minimize noise coupling. Add a ground pour under the MCU and route analog/digital grounds separately, joining them at a single point near the VSS pin. The RESET pin requires an external 10 kohm pull-up to VDD; do not leave it floating during power-up or the part may enter test mode.
Do not exceed 5.5V on VDD - the part lacks an absolute-max clamp and over-voltage will damage the internal regulator. The BKGD/MS pin must be held high during reset; a floating BKGD pin prevents normal startup. The 4KB Flash limit means inefficient code or large constant tables will exhaust memory; use the compiler's --code-size optimization flags. For I²C communication, ensure external pull-ups (4.7 kohm) are present on SDA and SCL - the MCU's internal weak pull-ups are insufficient for reliable bus operation above 100 kHz.
If using the internal clock source, no crystal layout is needed. If routing to an external crystal/resonator, keep the traces under 5 mm and surround them with ground. The through-hole DIP-20 footprint requires 0.1 inch pin pitch holes on the PCB; do not mix it with SOIC-20 footprints. Pin 1 marker is the dot on the package, located near the VDD pin.
Compliance-Informationen
Part is End-of-Life per NXP. RoHS and REACH status not explicitly stated in the verified web data. AEC-Q100 not qualified per the datasheet; temperature grade is automotive (-40C to +125C) but not formally AEC-Q100 certified.
