MC9S08RD32PE 概要
A microcontroller is a programmable semiconductor device that combines a CPU core, memory, peripherals, and input/output functions on one integrated circuit. The S08 architecture is an 8-bit CISC-style embedded-control core commonly used in industrial, appliance, consumer, and communications equipment. MC9S08RD32PE belongs to the broader semiconductor hierarchy of MCU, embedded processor, and embedded-control IC.
Key verified attributes include an 8-bit MCU architecture, 8 MHz operating frequency, 32 KB Flash memory organized as 32K x 8, and a 28-pin PDIP package. Distributor records also identify the part as an S08 microcontroller and list its operation at 2.5 V or 3.3 V. Exact RAM, peripheral, temperature, timing, and package-dimension values require confirmation from the manufacturer datasheet before final design release.
The device is suitable for motor and relay control, sensor acquisition, industrial control panels, appliance controllers, embedded instrumentation, and communications modules. A designer should verify every peripheral, pin, electrical limit, and timing requirement against the applicable datasheet because the supplied search data does not include a complete electrical specification table.
The 28-pin PDIP package favors through-hole prototyping and legacy control boards. Confirm pin assignments, oscillator connections, programming interfaces, reset behavior, and supply decoupling before layout. Because the available records show distributor inventory references but do not provide a complete manufacturer lifecycle statement, lifecycle status is retained as active only for this generated data version.
This product page consolidates the verified distributor identity, package, Flash memory, clock, and supply information with sourcing and design considerations. It does not replace the manufacturer datasheet, which remains the controlling source for electrical limits, timing, pin definitions, and production qualification.

主な用途
MC9S08RD32PE の用途: 6 件s: Industrial Control Panels, Appliance Controllers, Sensor Acquisition and Conditioning, Relay and Motor Sequencing, Embedded Instrumentation, Legacy Communication Equipment.
Industrial Control Panels
MC9S08RD32PE fits an embedded industrial control panel requiring a dedicated 8-bit MCU, 8 MHz processing, and 32 KB Flash for control firmware. The 28-pin PDIP package is practical for prototypes, legacy boards, and hand-assembled control systems where through-hole construction simplifies inspection and rework. The designer should verify the exact GPIO count, timer resources, communication peripherals, and reset behavior in the datasheet before assigning inputs or outputs. Because the supplied data does not identify isolated I/O ratings, the MCU should be placed behind appropriate protection, driver, and signal-conditioning stages rather than connected directly to industrial loads.
おすすめ
Appliance Controllers
The MC9S08RD32PE is suitable as the central controller in an appliance when firmware fits within 32 KB Flash and the 8 MHz S08 performance is adequate for motor, valve, display, or sensor sequencing. Its 2.5 V or 3.3 V operating identification permits initial rail planning, while the PDIP package supports prototype and repair work. A production appliance normally needs robust brownout behavior, relay-driver transistors, isolated sensing, and careful grounding; those specifications are not present in the supplied search data. Verify watchdog, timers, ADC, communication interfaces, and electrical limits before finalizing the appliance control architecture.
おすすめ
Sensor Acquisition and Conditioning
MC9S08RD32PE can serve as the digital controller for a sensor-acquisition module when the system requires low-to-moderate processing complexity, nonvolatile 32 KB firmware storage, and an 8 MHz embedded-control core. The MCU can coordinate sensor enable timing, digital filtering, status reporting, and actuator commands after the analog front end performs amplification and filtering. The supplied data does not specify ADC resolution, analog pins, sample rate, or sensor interfaces, so analog capability must be verified directly in the manufacturer datasheet. The 28-pin PDIP package also makes this approach useful for breadboard prototypes and laboratory instrumentation before a smaller production package is selected.
おすすめ
Relay and Motor Sequencing
The MC9S08RD32PE is appropriate for deterministic relay, solenoid, stepper, or small-motor sequencing when its 8 MHz S08 core can execute the required state machine and the confirmed 32 KB Flash is sufficient for firmware. Outputs should drive transistors or gate drivers rather than load contacts directly. Timing, pulse-width limits, flyback protection, current limits, and thermal conditions must be taken from the complete MCU and driver documentation; none are quantified in the supplied results. The PDIP package is advantageous for first prototypes because each pin is accessible for probing, but production designs may migrate to a smaller package after pin compatibility and board redesign are complete.
おすすめ
Embedded Instrumentation
MC9S08RD32PE can be used in a compact laboratory or field instrument for status sequencing, local display control, switch handling, data acquisition coordination, and communications support when the application does not require a high-performance CPU. The 8 MHz clock and 32 KB Flash provide a clear baseline for firmware planning, while the 28-pin PDIP package supports educational builds and repairable prototypes. A complete design still needs confirmed UART, SPI, I2C, timer, ADC, and GPIO specifications, none of which are provided here. Use a hardware programming interface and conservative reset circuitry, and validate timing margins before adding measurement algorithms.
おすすめ
Legacy Communication Equipment
MC9S08RD32PE may be appropriate for a legacy communication device that already uses the S08 ecosystem, provided its serial peripherals, baud-rate support, memory map, and programming method are verified. The confirmed 8 MHz CPU and 32 KB Flash can support protocol framing, command handling, status reporting, and supervisory logic in compact equipment. Do not assume that any listed related MCU is pin-compatible: the supplied data only confirms the target package and core attributes. For repair or clone designs, compare the complete datasheet pinout, register map, interrupt vector table, timing, and supply requirements with the original board before substituting a part.

設計ノート
Do not treat a related S08 MPN as interchangeable merely because it has a similar family name. Before substituting MC9S08RD16PE or another candidate, compare the complete 28-pin PDIP pinout, supply limits, Flash and RAM sizes, peripheral mapping, oscillator requirements, programming interface, interrupt behavior, and timing. The supplied records do not provide a complete compatibility matrix, so a board-level review and datasheet comparison are mandatory.
For a prototype board, provide a short, direct supply path to the MCU and place the required bypass capacitors close to the device power pins. Preserve the package pin numbering from the manufacturer datasheet, provide a defined reset path, and route oscillator and programming signals away from noisy switching nodes. Because the supplied data does not specify the pinout or decoupling values, use the datasheet rather than estimating them.
Plan the external power tree around the identified 2.5 V or 3.3 V operating options, but verify minimum and maximum supply limits, startup behavior, brownout thresholds, and input current from the manufacturer documentation. Use transistor or gate-driver stages for relays, motors, solenoids, and high-current LEDs. Estimated power dissipation and thermal rise cannot be calculated from the supplied data because current draw and junction-temperature limits are missing.
Keep the 28-pin PDIP MCU away from high-current switching paths and use a compact ground return around the device. Separate analog sensor wiring from relay and motor traces, add flyback protection on inductive loads, and use a stable clock source according to the datasheet. The large through-hole package simplifies probing, but production layouts should be re-reviewed before converting to a smaller package because land patterns and pin availability may differ.
コンプライアンス情報
