MC9S08SH16CWLR 概要
The S08 is an 8-bit CISC microcontroller family intended for embedded control applications where low cost, compact size, and integrated peripherals are important. This part combines a 40 MHz CPU core with flash memory, RAM, serial interfaces, timers, pulse-width modulation, watchdog and reset supervision, and a multichannel ADC. Its 23 I/O pins provide access to the integrated peripherals in a single package.
Verified specifications identify a 40 MHz operating speed, 16KB (16K x 8) flash memory, 1K x 8 RAM, 23 I/O pins, and an internal oscillator. The device supports I2C, LINbus, SCI, and SPI connectivity according to the supplied component listing. Its 16-channel ADC provides 10-bit resolution, while the listed peripheral set includes low-voltage detection, power-on reset, PWM, and a watchdog timer.
The 28-pin SOIC package is approximately 7.50 mm wide and 0.295 inch long according to the verified specification snippet. The listed operating voltage options are 3.3 V and 5 V. The MC9S08SH16CWLR is suitable for compact embedded systems, low-cost control products, sensor interfaces, actuator controllers, and serial-connected industrial equipment where an 8-bit architecture and integrated peripherals are sufficient.
A key sourcing consideration is lifecycle status. The supplied PDF source lists the part as obsolete, while distributor pages provide product information and ordering links. Engineers should confirm availability, remaining supply, and any authorized-source restrictions before beginning a new design. A replacement should be verified for pinout, memory size, voltage range, peripheral compatibility, clock requirements, and software support.
The most important design step for a redesign is to treat software migration as part of the replacement assessment. A device with the same package name may differ in flash capacity, peripheral mapping, interrupt behavior, or clock configuration. This page consolidates the verified source specifications, lifecycle information, package identity, sourcing limitations, and drop-in alternatives while distinguishing confirmed data from information that still requires engineering validation.

主な用途
MC9S08SH16CWLR の用途: 6 件s: Legacy Embedded Control, Sensor and Signal Conditioning, Serial Connected Instrumentation, Actuator and Motor Control, Human-Machine Interface Controller, Battery-Powered Portable Module.
Legacy Embedded Control
The MC9S08SH16CWLR is suitable for maintaining an existing embedded-control design that depends on the 8-bit S08 architecture. Its verified 40 MHz core and 16KB flash provide room for compact control firmware, while 1KB RAM and 23 I/O pins support simple digital control tasks. The listed I2C, LINbus, SCI, and SPI interfaces can connect local sensors, actuators, and service adapters. Because the part is obsolete, engineers should preserve the original firmware toolchain and verify every register, interrupt, and pin-mux setting against the exact datasheet.
おすすめ
Sensor and Signal Conditioning
The integrated 16-channel, 10-bit ADC makes the MC9S08SH16CWLR relevant to low-cost sensing systems that monitor several analog inputs. It can be used in industrial panels, simple condition-monitoring equipment, and compact control modules where 10-bit measurement resolution is adequate. The 3.3 V and 5 V operating options provide flexibility in system power architecture, while I2C, SCI, and SPI support external sensors and digital processing. ADC reference, sample-time, and input-channel details must be confirmed from the family datasheet before setting analog scaling or sampling rate.
おすすめ
Serial Connected Instrumentation
The listed SCI and SPI connectivity makes this MCU appropriate for legacy instruments that communicate with a host controller, display, flash memory, or peripheral bridge. The 40 MHz S08 core can manage deterministic protocol handling and embedded application logic without an external processor. I2C and LINbus further support mixed embedded-system designs. Because no detailed baud-rate, pin-mux, or timing data is supplied, the designer must review the exact MC9S08SH16 documentation before assigning connectors, isolating interfaces, or selecting pull-up and level-shifting components.
おすすめ
Actuator and Motor Control
The verified PWM capability and 23 I/O pins make the MC9S08SH16CWLR a candidate for small actuator, valve, pump, or simple motor-control products. The 8-bit core can execute sequencing and protection logic, while the watchdog, low-voltage detection, and power-on reset features support robust embedded operation. This is not a high-performance motor-controller platform, so timing, PWM resolution, and output-drive ratings must be checked in the datasheet. External drivers may still be required depending on load current and voltage.
おすすめ
Human-Machine Interface Controller
The MCU can serve as the local controller for compact keypads, status indicators, menu systems, and small display modules. Its 23 I/O pins provide a practical interface budget for buttons, LEDs, and external display drivers, while SCI or SPI can connect to a higher-level display or communication controller. The 16KB flash capacity is suitable for modest embedded firmware, and the watchdog can help recover from software faults. The supplied data does not specify GPIO drive strength or timing, so display and driver interfaces require electrical verification.
おすすめ
Battery-Powered Portable Module
The 3.3 V and 5 V operation options make the MC9S08SH16CWLR suitable for compact portable modules when the legacy S08 software and peripheral set are already established. It can coordinate sensors, low-power communication, and simple actuator outputs in devices such as portable meters or field-service modules. Low-power design cannot be finalized from the supplied snippets because sleep current, active current, and clock-tree details are absent. Review the datasheet, disable unused peripherals, and measure the final current budget in the intended operating mode.

主な差別化要因
- Closest verified same-family alternative （vs MC9S08SH16CWL)
- Obsolete-source status requires migration planning （vs MC9S08SH32CWLR)
- Integrated mixed-serial peripheral set （vs MC9S08SH16CWL)
設計ノート
Do not treat a related S08-family MPN as an automatic replacement. The verified comparison identifies MC9S08SH16CWL as the closest candidate, but it also notes that electrical characteristics may differ. Before releasing a substitute, compare the complete pinout, alternate functions, supply limits, clock setup, memory map, interrupt vectors, ADC channels, timer modules, and serial peripheral assignments against the original design. The target is obsolete, so undocumented substitutions can create failures that are expensive to diagnose after fabrication.
Design the 3.3 V and 5 V rails with the exact absolute maximum and operating limits from the MC9S08SH16 family datasheet. The supplied data identifies 3.3 V and 5 V operation but does not provide current consumption, regulator-dropout requirements, or absolute maximum ratings. Check startup behavior, brownout thresholds, low-voltage detection, and power-on reset timing before using the MCU in a battery or industrial supply system. Add local decoupling close to the supply pins according to the manufacturer layout guidance once those values are confirmed.
Reserve the 28-pin SOIC footprint for the verified package and keep sensitive analog and serial routes away from switching nodes. The ADC uses 16 channels at 10-bit resolution, so trace routing, ground return, and reference-decoupling decisions can affect measurement repeatability. Place input and output components according to the datasheet pin table, verify alternate-function multiplexing, and confirm that the SOIC package matches the PCB land pattern. The supplied data does not provide the complete pin mapping, so no pin-specific layout should be released without the manufacturer document.
Do not infer low-power performance from the 40 MHz maximum CPU frequency or the 3.3 V and 5 V labels. Active current, sleep current, peripheral clock behavior, and shutdown behavior are not present in the verified snippets. Measure current across the actual firmware modes, disable unused peripherals, and validate the result against the published operating conditions. This is particularly important for portable modules, where a legacy replacement may retain the same nominal speed but differ in clock or low-power behavior.
コンプライアンス情報
The supplied verified data does not provide RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals declarations for this exact MPN.
