MC9S08RD32CDWE - 8-Bit 8MHz 32KB MCU | NXP | SOIC-28
N.º de pieza: MC9S08RD32CDWE ✗ Fin de vidaMC9S08RD32CDWE Descripción general
A microcontroller is a programmable semiconductor that integrates a processor core, memory and peripherals into one device. The S08 family is positioned for cost-sensitive embedded control, while the MC9S08RD32 device provides 32K × 8 flash organization for firmware storage. In the broader hierarchy, this part is an MCU, a semiconductor and a member of the NXP S08 microcontroller family.
The key verified features are the 8-bit CPU, 8 MHz operating speed, 32 KB flash memory and 28-pin SOIC package. These values are suitable for compact embedded controllers that need a dedicated nonvolatile program memory area. The distributor listings also describe the part as lead-free, but no detailed environmental, supply-voltage, RAM, timer, serial-interface or temperature data were supplied in the verified source set.
Because the provided sources do not include a complete manufacturer datasheet, electrical limits and peripheral assignments should not be inferred from the MPN alone. Designers should consult the applicable NXP or Freescale datasheet before fixing supply voltage, peripheral connections, reset behavior and timing. The 28-SOIC footprint also requires a board layout that matches the exact land pattern and pin numbering of this variant.
Typical embedded uses for this class of part include simple motor or relay control, keypad interfaces, sensor acquisition, LED indication and low-power control panels. The 8 MHz processing rate and 32 KB flash storage are concrete selection criteria for these designs. A practical design should reserve programming/debug access, decouple the supply rails as specified by the full datasheet, and validate reset and unused-pin behavior on the production PCB.
This page consolidates the verified distributor identity, package, memory and clock data with structured sourcing and honest limitations. It is intended to help engineers locate the correct MCU documentation, compare sourcing records and assess whether the 8-bit, 32 KB, 8 MHz device matches a legacy embedded-control design before requesting a quote.

Aplicaciones típicas
MC9S08RD32CDWE es adecuado para 6 aplicacións: Simple Motor-Control Controller, Keypad and Human-Interface Control, Sensor Signal Conditioning and Monitoring, LED Sign and Indicator Control, Industrial Relay and Discrete Control, Legacy Embedded Product Maintenance.
Simple Motor-Control Controller
MC9S08RD32CDWE is a candidate for an 8-bit embedded motor-control or relay-control controller because the verified device provides an 8-bit MCU core, 8 MHz clock and 32 KB flash memory. It can execute sequencing logic, debounce commands and coordinate simple actuator outputs when the application does not require a larger processor. The 32K × 8 flash organization provides a defined firmware-memory target, while the 28-SOIC package supports conventional through-hole assembly. Verify PWM, timer, ADC, supply-voltage and temperature requirements in the complete datasheet before selecting it.
Recomendado
Keypad and Human-Interface Control
The 8 MHz S08 MCU architecture and 32 KB flash capacity suit simple keypad scanning, mode selection and LED feedback panels. MC9S08RD32CDWE can store the control firmware locally while an 8-bit processor handles debouncing and state-machine updates. The 28-SOIC package is practical when a controller board needs a larger through-hole assembly footprint than a fine-pitch device. Before layout, verify the actual I/O count, pin multiplexing, debounce timing and supply limits because those details are not contained in the supplied distributor snippets.
Recomendado
Sensor Signal Conditioning and Monitoring
MC9S08RD32CDWE can be evaluated for low-complexity sensor monitoring when the selected sensor interface is compatible with its verified 8-bit processing rate and 32 KB program memory. Typical tasks include periodic sampling, threshold comparison, digital filtering, event logging and communication formatting. The known 8 MHz clock provides a concrete timing reference for basic control-loop calculations, but ADC resolution, acquisition timing, serial peripherals and supply range are not included in the verified data. Confirm those specifications and pin assignments before treating it as a sensor-node solution.
Recomendado
LED Sign and Indicator Control
The MC9S08RD32CDWE is appropriate for consideration in simple LED sign, status-indicator or annunciator controllers where firmware manages multiple outputs, timing patterns and user commands. Its verified 8-bit architecture and 8 MHz clock are appropriate for basic sequencing, while 32 KB flash provides storage for fixed display logic and configuration behavior. The 28-SOIC package allows a conventional assembly process and clear routing on a moderately sized board. Verify GPIO count, port mapping, current-drive limits and supply details from the full manufacturer documentation.
Recomendado
Industrial Relay and Discrete Control
MC9S08RD32CDWE can be assessed for relay sequencing, discrete alarm control and small industrial automation modules where the firmware is straightforward and the system does not require a high-performance processor. The verified 8 MHz clock supports deterministic low-complexity tasks, and 32 KB flash stores application logic without an external program-memory device. The device may be useful in legacy control equipment that already uses an S08 toolchain. Its suitability still depends on verified I/O, timing, reset, electrical and environmental limits, none of which are supplied in the current source set.
Recomendado
Legacy Embedded Product Maintenance
MC9S08RD32CDWE is relevant to maintenance and second sourcing of legacy embedded products because its verified identity includes the S08 family, 8 MHz clock and 32 KB flash memory. The MCU can fit an existing board only after confirming the package footprint, pinout, memory organization, supply requirements and firmware behavior. A distributor record may show the part under NXP, Freescale Semiconductor or Motorola Mobility, reflecting sourcing history rather than a verified change in electrical specification. Preserve the original package suffix and validate a replacement sample before production release.

Notas de diseño
Use the exact 28-SOIC land pattern associated with the MC9S08RD32CDWE package suffix and preserve the manufacturer's pin numbering. Place the decoupling network at the device supply pins and route programming, reset and ground connections according to the complete datasheet layout recommendation. The verified data confirms a 28-SOIC package but does not provide the pin table, so do not finalize a schematic or footprint from the MPN alone. Validate the assembled outline and lead pitch against the official package drawing.
Before powering the board, confirm the target device's supply-voltage range, absolute maximum ratings, reset thresholds and peripheral drive limits from the complete manufacturer datasheet. The supplied sources provide no operating voltage or current limits. Check every rail and I/O connection against those values, especially if the board retains legacy peripherals. A distributor description of the part as lead-free does not define its electrical operating envelope, so use the datasheet and measured board requirements rather than inferring safe limits.
The manufacturer or distributor identity associated with MC9S08RD32CDWE may appear as NXP, Freescale Semiconductor or Motorola Mobility across the verified records. Treat those entries as sourcing history, not proof of a different electrical variant. When maintaining a design, confirm the date code, package suffix, memory configuration and lifecycle status before substitution. Also verify the firmware image, oscillator setup, reset behavior and peripheral mapping; a matching MPN string alone does not guarantee production interchangeability.
Información de cumplimiento
The verified Mouser result explicitly describes MC9S08RD32CDWE as an AQUILA SOIC lead-free MCU. RoHS, REACH, halogen-free and conflict-minerals status are not explicitly provided and are therefore recorded as unknown. AEC-Q100 status is not_applicable because the verified sources do not identify an automotive-qualified variant.
