MC9S08SH4CSC 概要
An S08 microcontroller is an embedded-processing device that combines a processor core, program memory, data memory, and peripherals on one semiconductor package. In the broader hierarchy, it is an 8-bit microcontroller, an embedded controller, and a semiconductor intended for control-oriented products. The MC9S08SH4CSC is suited to applications where simple firmware, peripheral integration, and compact board area are more valuable than a high-performance 32-bit architecture.
The main verified features are 40 MHz maximum operating frequency, 4 KB internal flash, 512 B RAM, and integrated USB 2.0. The S08 family also provides an enhanced HCS08 CPU with support for up to 32 interrupt/reset sources. These figures make the device relevant for USB-connected peripherals, compact control modules, and cost-constrained embedded products. A separate third-party comparison also describes an enhanced HCS08 CPU with a 20 MHz bus, but the supplied search data does not establish that value as a formal MC9S08SH4CSC specification.
Typical uses include low-cost USB dongles, simple human-interface-device controllers, compact motor or relay-control boards, instrumentation interfaces, and other 5 V embedded systems. The SOIC-8 package supports conventional surface-mount assembly and is easier to handle than a very fine-pitch package in low- or medium-volume production.
Designers should verify the exact pin functions, USB electrical requirements, clock configuration, and programming workflow in the NXP datasheet before layout release. Because the supplied results contain inconsistent package references from third-party aggregators, the target should be treated as an SOIC-8 device based on the distributor and manufacturer listings, while uncertain electrical details remain marked for verification.
This page consolidates the verified manufacturer and distributor information, separates confirmed specifications from unavailable parameters, and highlights sourcing and replacement limitations for an end-of-life low-cost MCU.

主な用途
MC9S08SH4CSC の用途: 6 件s: USB Embedded Peripheral, Cost-Sensitive 5V Control Module, Human Interface Device Controller, Compact Motor and Relay Control, Portable Instrumentation Interface, Embedded Educational and Prototype Platform.
USB Embedded Peripheral
MC9S08SH4CSC fits a compact USB peripheral when the product needs an 8-bit controller rather than a higher-performance application processor. Its verified 40 MHz S08 core, 4 KB flash, 512 B RAM, and integrated USB 2.0 provide a small control platform for configuration, status reporting, and device-class firmware. The design should reserve pins and routing for USB data, provide the required decoupling, and validate enumeration and suspend behavior on the final board. Because the part is marked End of Life, prototype and production planning should include supply risk and a qualified migration path.
おすすめ
Cost-Sensitive 5V Control Module
The MC9S08SH4CSC is suited to simple 5 V control modules where a small 8-SOIC footprint and integrated USB are useful. It can execute sequencing and state-machine firmware for relays, indicators, keypads, or actuator interfaces without requiring a larger microcontroller package. Its 40 MHz operating rating provides processing headroom, while 4 KB flash limits the application image and 512 B RAM constrains buffering. Firmware designers should measure code size during development and confirm the exact supply-voltage limits, reset behavior, and peripheral assignments from the NXP datasheet before schematic release.
おすすめ
Human Interface Device Controller
MC9S08SH4CSC can serve as the controller for a compact keyboard, button panel, or configuration interface connected through USB. The integrated USB 2.0 feature is the main fit criterion, while the 8-bit S08 core handles debouncing, report formatting, and low-bandwidth device logic. A production design must verify USB data-line routing, pull-up or pull-down requirements, power budgeting, and enumeration timing. The 4 KB flash budget should be treated as a firmware constraint, and the 512 B RAM figure should be checked against descriptor and buffering requirements. Since lifecycle status is End of Life, a second-source strategy is important.
おすすめ
Compact Motor and Relay Control
MC9S08SH4CSC is appropriate for a compact controller that coordinates relays, motors, indicators, or digital actuators through deterministic firmware. The 40 MHz S08 processor provides more timing headroom than a very low-clock microcontroller, while the SOIC-8 package keeps the control section compact. The MCU should be placed near the regulated logic supply and separated from noisy motor paths, while power transistors and protection components handle the actual load current. Verify the target’s timer, GPIO, analog, and supply specifications in the datasheet before selecting it for safety-critical or high-current systems. Use a qualified replacement plan because the part is End of Life.
おすすめ
Portable Instrumentation Interface
MC9S08SH4CSC can be used as a USB-connected interface controller in portable measurement or diagnostic equipment. The integrated USB 2.0 connection can simplify host communication, while the 40 MHz S08 core handles command parsing, status reporting, and low-rate control functions. With only 4 KB flash and 512 B RAM, the device is best positioned as a communications and supervisory controller rather than the primary high-volume data processor. Keep analog and power circuitry away from USB routing, validate grounding and cable ESD protection, and verify the exact ADC or comparator requirements separately because the supplied target data does not establish them.
おすすめ
Embedded Educational and Prototype Platform
MC9S08SH4CSC works as a compact learning target for embedded-control experiments involving USB firmware, interrupts, timers, and simple sensor interfaces. Its small SOIC-8 package makes it practical for a custom breakout board, while the 40 MHz specification and familiar S08 architecture support timing demonstrations and state-machine examples. The device is also suitable for evaluating low-cost USB data acquisition or control prototypes. However, the limited 4 KB flash and 512 B RAM require careful example selection, and the End of Life designation should be included in the lesson plan so students understand lifecycle and sourcing constraints.

設計ノート
Verify the target-specific supply-voltage limits, decoupling requirements, and USB power requirements in the NXP datasheet before schematic release. The supplied search data supports a 5 V application context but does not establish the absolute voltage range. Place the MCU's required bypass capacitors close to the supply and ground pins, and keep USB transceiver or connector supply current separate from sensitive analog paths where possible.
Treat the SOIC-8 footprint as a compact but pin-limited layout. Route USB data lines as a controlled pair, minimize stubs, provide the datasheet-required termination or biasing, and keep switching or motor-current paths away from the MCU ground reference. Because the verified source does not include the complete pin assignment, do not finalize a footprint-only PCB library entry until the official pinout and package drawing are checked.
Do not substitute a related S08SH part solely because its frequency and flash memory appear similar. Check every pin, USB behavior, reset scheme, clock configuration, memory map, and peripheral difference. The supplied alternatives are presented as engineering candidates for review; the search data does not establish that all are true drop-in replacements, so validate hardware and firmware before production use.
The supplied data does not provide a power-dissipation value, junction-temperature limit, or package thermal resistance for MC9S08SH4CSC. Do not calculate a thermal margin from an assumed figure. Use the manufacturer electrical characteristics and the actual USB, I/O, and supply loads, then apply the package thermal data from the official datasheet during thermal design.
コンプライアンス情報
The supplied verified results identify the manufacturer, package, memory, frequency, USB feature, and lifecycle status, but do not provide RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals declarations.
