MC9S08RC32FJ - 8-Bit 8MHz 32KB Flash MCU | NXP

The NXP Semiconductors MC9S08RC32FJ is an 8-bit S08 microcontroller operating at 8 MHz, with 32 KB of flash program memory and a 32-lead LQFP package measuring 7 mm by 7 mm. Its operating supply range is 1.8 V to 3.6 V, making it suitable for compact embedded systems that use low-voltage 3.3 V power rails. The MCU is identified as an S08-series device with 32 KB organized as 32K by 8 bits. A microcontroller is a programmable semiconductor that integrates a processor core, program memory, data memory, and peripherals into one device. The S08 architecture belongs to the broader category of 8-bit embedded microcontrollers, which are commonly used for control, sensing, and actuator-management tasks. At 8 MHz, the MC9S08RC32FJ provides deterministic processing capability for products where a low-cost, low-power controller is preferable to a more complex application processor. The MC9S08RC32FJ combines 32 KB of flash memory with an 8 MHz operating frequency in a 32-LQFP package. The 1.8 V to 3.6 V operating range supports direct operation from common low-voltage rails, while the 7 mm by 7 mm package provides a surface-mount solution for compact assemblies. Its 32-terminal gull-wing package also exposes more interface connections than a smaller 20-pin controller package, supporting practical external sensing, communications, and control connections. This commercial-temperature S08 microcontroller is positioned for embedded control designs that require an established 8-bit architecture and an adequate balance of flash memory, processing speed, and package size. The 32 KB program-memory capacity can hold application firmware, configuration logic, and control routines. Because the device is identified as an 8-bit MCU, software timing and interrupt handling should be evaluated against the workload rather than compared directly with 16-bit or 32-bit processors. Typical uses include small motor and relay controllers, building-control interfaces, appliance control panels, industrial sensing nodes, and compact consumer products. Its 8 MHz operating speed is appropriate for supervisory control loops, button and sensor management, status indication, and communications handling. Designs that require substantially more code space, higher processing throughput, or a different pin count should evaluate another MCU in the S08 family or a device from another embedded-controller architecture. The principal design consideration is ensuring that the LQFP footprint, pin assignment, flash requirement, voltage range, and peripheral configuration match the intended PCB. Use the pin-description table in the manufacturer datasheet when assigning tracks, and confirm the board's exposed thermal and manufacturing requirements before release. Firmware development should also account for the S08 peripheral configuration and memory map used by the selected software toolchain. This page organizes the available specifications, package information, practical application guidance, and confirmed family alternatives into one engineering reference. It also identifies unsupported electrical, timing, peripheral, and environmental details for verification against the manufacturer datasheet before a production design is released.

The NXP Semiconductors MC9S08RC60FG is an 8-bit S08 microcontroller with an 8 MHz clock, 60 KB of Flash memory, and a 44-LQFP package measuring 10 mm by 10 mm. It is designed for embedded control applications that require deterministic digital control, compact packaged logic, and embedded program-and-data memory in one device. An S08 microcontroller is an 8-bit embedded-control platform within the broader hierarchy of microcontrollers, embedded processors, and semiconductor devices. The MC9S08RC60FG combines a byte-oriented processor core, Flash program memory, and integrated peripherals in a surface-mount package. This combination allows control logic, communications, and product-specific functions to be consolidated without requiring a separate external memory device when the application's requirements fit within the available resources. The headline device characteristics are an 8-bit processing architecture, an 8 MHz operating clock, and 60 KB of Flash memory. Its 44-LQFP package provides 44 externally accessible or assigned positions and is offered in a 10 mm by 10 mm physical format. The MC9S08RC60FG is therefore suited to compact embedded controllers where deterministic firmware execution, integrated nonvolatile storage, and moderate logic complexity are more important than high processor throughput. The S08 architecture is intended for embedded products in which peripherals and firmware can be assigned directly to application functions. Compared with a larger 16- or 32-bit processor, an 8-bit controller can provide sufficient computation for motor, display, appliance, and industrial-control tasks while preserving a straightforward programming model. The 60 KB Flash allocation provides meaningful firmware space for protocol handling, state machines, calibration data, and background routines, although final memory budgeting must include the linker map and boot-code requirements. Typical uses include appliance controllers, small motor-control boards, keypad and display interfaces, instrumentation, industrial modules, and low-cost embedded products. A design may use the MCU to read inputs, execute a control algorithm, update an output, and manage communication through its integrated peripherals. The 8 MHz clock supports straightforward event-driven firmware, while the available Flash supports more extensive application code than many compact 8-bit controllers. The principal design consideration is to verify the exact peripheral allocation, electrical limits, reset behavior, and programming configuration for the MC9S08RC60FG. Engineers should preserve the 44-LQFP land pattern, follow the manufacturer's decoupling and signal-routing guidance, and confirm the controller's unused-pin requirements. Review the complete pin-description and connection tables in the manufacturer datasheet before assigning every package terminal. This product page organizes the confirmed device identity, package, clock, memory, sourcing path, and engineering considerations into one engineering reference. It also distinguishes confirmed characteristics from parameters that require confirmation in the full manufacturer documentation, helping designers make a faster and safer component-selection decision.

The 44-pin package provides substantially more external connection options than small-outline packages, making the device practical for designs needing multiple I/O signals or mixed analog and digital functions. MC9S08RC8CFG can be considered for industrial controls, consumer appliances, instrumentation, motor and relay control, sensor interfaces, and compact embedded modules. Its 8MHz clock is generally sufficient for supervisory loops, keypad and display handling, communication management, and deterministic low-to-moderate-complexity control. The part is available through multiple distributors, and one verified listing reports an in-stock starting price of $1.4906, while another reports a price of $4.0627; prices should therefore be checked by quantity, condition, and authorized distributor inventory as of 2026-10-30. For PCB design, verify the exact pin assignments, exposed-pad requirements, decoupling recommendations, and operating-temperature limits in the MC9S08RC8 datasheet before layout release. Because the supplied search results do not include a complete manufacturer pin table, the pinout is intentionally left unavailable rather than presenting guessed pin numbers. Likewise, final peripheral counts, timer resources, ADC specifications, communication interfaces, and electrical timing characteristics require confirmation from the authoritative device documentation.

The verified distributor listing identifies the device as an S08 MCU with 8 KB (8K x 8) Flash and a 32-LQFP (7 x 7) package. Its combination of an 8-bit architecture, compact package and embedded Flash suits cost-sensitive embedded-control designs that require deterministic peripheral-driven operation rather than a high-performance application processor. An S08 microcontroller is a member of the 8-bit embedded-microcontroller hierarchy, combining a CPU core, Flash program memory, data memory, timers, communication interfaces and interrupt control in one integrated circuit. Compared with larger 16-bit or 32-bit MCU families, the MC9S08RC8CFJ provides a straightforward platform for motor control, appliance control, instrumentation and compact embedded products. Its role within an electronic system is to execute firmware, acquire external signals and coordinate actuators or communications. The principal verified features are an 8-bit processor operating at 8 MHz, 8 KB of Flash organized as 8K x 8, and a compact 32-LQFP package. The Flash memory provides space for application code and fixed firmware, while the low pin count supports space-constrained boards. Distributor availability data identifies stocked units from multiple sources, including 33,920 pieces reported by Wolfchip on December 24, 2025, although individual inventory levels can change rapidly. The S08 architecture is intended for embedded applications in which predictable I/O handling, compact PCB area and simple tool-supported development are more important than high computational bandwidth. The MC9S08RC8CFJ can serve as the central controller in a keypad interface, a small motor or relay controller, a sensor-processing module or a communication endpoint. Its Flash-based program model also allows firmware to be retained without an external program-memory device. Typical applications include industrial controls, consumer appliances, automotive accessories and compact instrumentation. In each case, the MCU can read sensors through its peripheral interfaces, execute control logic and update outputs without requiring a separate processor. The 32-LQFP footprint also simplifies transition from a larger prototype package to a production board when the pin count and thermal design remain suitable. The primary design consideration is to verify all electrical limits, pin multiplexing, clock configuration and peripheral assignments against the manufacturer datasheet before PCB release. Because the supplied verified data does not provide individual pin names, voltage limits, current ratings or memory-map details, those values are intentionally not guessed here. A reliable design should also include appropriate decoupling and a conservative operating strategy around temperature and supply-voltage limits. This page consolidates verified distributor specifications, current pricing references, strict same-package replacement guidance, comparison parameters and practical selection notes. It is intended to help engineers distinguish verified MC9S08RC8CFJ characteristics from unconfirmed device details and to identify the information that must still be checked in the authoritative datasheet before hardware release.

MC9S08RD16CDWE - 8-bit S08 MCU, 16KB Flash, 8MHz | NXP
MC9S08RD16CDWE

MC9S08RD16CDWE - 8-bit S08 MCU, 16KB Flash, 8MHz | NXP

The NXP (formerly Freescale) MC9S08RD16CDWE is an 8-bit S08-family microcontroller built around the HCS08 CISC core, integrating 16KB of on-chip FLASH program memory, 2KB of RAM, and a rich peripheral set into a 28-pin wide-body SOIC (SOIC W) package. The part runs at a bus frequency of up to 8MHz from a 2.5V or 3.3V supply and is positioned as a general-purpose ultra-low-cost embedded controller for cost-sensitive industrial and consumer designs. A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory (FLASH/ROM), working memory (RAM), and peripherals such as timers, ADC, communication interfaces (UART, SPI, I2C), and general-purpose I/O onto one die. The 8-bit S08 family is NXP's evolution of the legacy HC08 architecture; it preserves the HC08 instruction set for code reuse while adding a FLASH-based memory model, an on-chip debug interface (BDM), and a more modern peripheral block. Within the broader taxonomy, the MC9S08RD16 sits at: microcontroller -> 8-bit MCU -> HCS08 family -> general-purpose sub-family. Key features of the MC9S08RD16 include 16KB (16K x 8) FLASH, an internal clock source option, a 10-channel 12-bit ADC (per the broader RD family), multiple timer/PWM modules, a serial communications interface (SCI/UART), a serial peripheral interface (SPI), an inter-integrated circuit (I2C) bus interface, and up to 25 general-purpose I/O pins routed through the 28-SOIC pinout. The part is offered in the SOIC-28 wide-body (7.50mm / 0.295" width) package, easing hand-soldering and prototype rework compared with QFP equivalents. From an architectural standpoint, the HCS08 core delivers roughly 1.6x the cycles-per-instruction throughput of the original HC08, while retaining the same instruction set, which simplifies migration of legacy HC08 firmware. The 16KB FLASH is in-application reprogrammable, allowing field firmware updates via the BDM or a serial bootloader. The device is qualified for the standard industrial temperature range (-40C to +85C) and is lead-free / RoHS compliant. Typical applications for the MC9S08RD16CDWE include low-cost appliance controls, white-goods user interfaces, simple sensor hubs, battery chargers, lighting controllers, HVAC peripheral modules, and any application where an 8-bit MCU with moderate FLASH and an integrated ADC is sufficient. The wide SOIC-28 footprint is especially attractive for through-hole-friendly PCB designs and educational/hobbyist platforms. When designing with this part, mind the 2.5V/3.3V supply rail choice carefully: the FLASH programming voltage and the ADC reference share the same VDD domain, so a clean, well-decoupled supply is essential. Decouple VDD with at least a 0.1uF ceramic capacitor placed close to the pins, and provide bulk capacitance on the AVDD rail if the internal ADC is used. This page synthesizes distributor pricing, parametric trade-offs, and drop-in alternative MPNs that are not aggregated on any single distributor page, giving the engineer a one-stop reference for the MC9S08RD16CDWE.

MC9S08RD16FG - 8-Bit 8MHz 16KB MCU | Motorola | 44-LQFP

Motorola MC9S08RD16FG is an 8-bit S08 microcontroller with an 8 MHz clock, 16 KB of flash memory, and a 44-LQFP package measuring 10 mm by 10 mm. The HC08/S08 processor combines embedded flash and microcontroller peripherals in a compact surface-mount package suited to cost-sensitive embedded control systems. A microcontroller is a programmable semiconductor that integrates a processor core, memory, and peripheral functions onto one device. The S08 architecture belongs to the broader 8-bit microcontroller family and is commonly used for compact control tasks involving digital inputs, outputs, timers, communications, and analog signal conditioning. Compared with a discrete processor design, an integrated MCU reduces component count, simplifies firmware deployment, and keeps the control system physically compact. The MC9S08RD16FG combines 16 KB of flash memory with an 8 MHz operating clock in a 44-pin LQFP package. Its flash-based program memory permits firmware to be retained when power is removed and updated through the device programming workflow. The 44-LQFP format provides substantially more external connections than smaller 8-bit packages, allowing more peripheral signals to reach the processor without requiring a larger board footprint. The S08 CPU is designed for embedded control rather than high-performance computing. Its 8-bit architecture is appropriate for sequential logic, timers, communication protocols, and system-state monitoring, while the 8 MHz clock establishes the device’s operating-rate class. Exact memory architecture, peripheral assignments, electrical limits, and timing figures should be confirmed against the manufacturer datasheet before schematic capture, firmware configuration, or PCB layout. Typical uses for this controller class include industrial panel controls, building and access equipment, appliance control boards, instrumentation, and compact motor-control interfaces. A 44-LQFP device is particularly useful when a design needs more I/O than a small-package MCU while retaining a straightforward embedded programming model. The 10 mm by 10 mm package also remains practical for multilayer boards where adequate escape routing is available. Design planning should begin with the manufacturer pin-description table and the electrical characteristics section. Confirm which peripheral functions are available on each package pin, whether unused pins require specific termination, what clock and reset connections are required, and which programming or debug interfaces are used. Component values, decoupling requirements, and allowed tolerances should follow the datasheet recommendations rather than generic MCU conventions. This product page consolidates the verified device identity, package information, sourcing path, technical alternatives, and application guidance into an engineering-focused reference. The comparison also distinguishes documented electrical facts from parameters that still require direct confirmation, helping designers evaluate the MC9S08RD16FG before committing it to an embedded-control design.

NXP Semiconductors MC9S08RD16FJ is an 8-bit S08 microcontroller rated for an 8 MHz operating frequency, with 16 KB of Flash program memory, in a 32-LQFP 7 x 7 mm package. It operates from 1.8 V to 3.6 V, making it suitable for low-voltage embedded control systems that need compact packaging, deterministic control, and a straightforward peripheral-oriented design. A microcontroller is a programmable embedded controller that combines a processor core, nonvolatile program memory, working memory, and peripherals on one semiconductor device. The S08 architecture belongs to the 8-bit microcontroller hierarchy, where an embedded CPU executes firmware while timers, serial interfaces, and input/output ports support real-time control tasks. Compared with a discrete logic controller, an MCU reduces component count and centralizes application behavior in firmware. The MC9S08RD16FJ combines a 16 KB Flash memory capacity with an 8 MHz clock in a 32-LQFP package. Its 1.8 V to 3.6 V operating range supports both low-voltage digital systems and industrial or consumer equipment operating from regulated 3.3 V rails. The 7 x 7 mm LQFP format provides a leaded, inspectable package option that can simplify assembly and prototype rework compared with a very small non-leaded package. This part belongs to the MC9S08RD16 family of S08 embedded processors and controllers. The product listing identifies the device as an 8-bit, 8 MHz MCU with 16K x 8 Flash memory, while the family name provides a consistent basis for firmware and hardware planning. Designers should verify the detailed clock, memory-map, peripheral, pin, and electrical limits in the manufacturer datasheet before fixing the operating configuration. Typical application areas include small sensor controllers, building-access peripherals, compact motor-control modules, industrial monitoring equipment, and low-power IoT endpoints. The MCU is particularly appropriate when the system requires local logic, serial communications, digital I/O, and firmware updates without the processing overhead of a 32-bit processor. Its 8 MHz clock is suitable for deterministic control loops that do not require intensive computation. A key design consideration is validating every electrical limit, peripheral function, and alternate-function assignment against the exact package pinout before schematic capture. Designers should also confirm that the selected Flash programming and debug workflow matches the S08 development toolchain. Because different MCU families require different peripheral setups and firmware initialization, software migration should not be treated as a drop-in operation. This product page consolidates the verified package, clock, memory, voltage-range, and architecture information into an engineering-oriented selection guide. It also identifies the information that must be checked in the manufacturer datasheet, helping teams distinguish a suitable replacement from a merely similar microcontroller before committing to a PCB or firmware revision.

MC9S08RD16PE-FR 8-Bit 16KB Flash MCU | NXP

The NXP Semiconductors MC9S08RD16PE-FR is an 8-bit HCS08 microcontroller operating at up to 8 MHz, with 16 KB of flash memory and a 28-pin plastic DIP package. It combines a compact general-purpose MCU platform with on-chip program flash in a through-hole package suited to legacy control systems, educational hardware, industrial controllers, and service instruments. A microcontroller is a programmable semiconductor that integrates a CPU core, memory, input/output ports, timers, and communication peripherals on one device. The HCS08 MCU belongs to the embedded-controller hierarchy: 8-bit microprocessor core, microcontroller, embedded processing IC, and semiconductor. Its on-chip flash permits firmware to be stored locally rather than in an external memory chip, simplifying both board design and field programming. The verified distributor data identifies the S08 family, an 8 MHz operating class, 16 KB organized as 16K x 8 flash, and a 28-pin plastic DIP package. The -FR ordering suffix is associated with the reel-packaged ordering designation, while the verified distributor listing identifies the target as a 28-PDIP. Additional electrical limits, timer resources, serial interfaces, ADC performance, operating temperature, and pin assignments are not present in the supplied source excerpts and therefore must be checked against the manufacturer datasheet before design release. The 28-PDIP form factor supports conventional through-hole assembly and hand-soldered prototypes. Its larger lead pitch and accessible package geometry make it useful where a fine-pitch surface-mount MCU would complicate inspection, rework, or education. Because this is a legacy MCU family, firmware, clock, reset, peripheral, and memory-map compatibility should be checked carefully when replacing another device. Typical uses include small control panels, sensor-conditioning systems, appliance controllers, laboratory fixtures, and legacy industrial interfaces. The 8 MHz S08 core and 16 KB flash provide sufficient resources for compact embedded logic, but they are not interchangeable with 16- or 32-bit processors when higher arithmetic throughput, larger memory, or high-speed networking is required. Design should begin with the exact datasheet pinout, supply limits, decoupling requirements, programming interface, and oscillator options. Validate every used pin, peripheral resource, and timing requirement because only the package, architecture, frequency class, and flash capacity are verified here. A careful schematic and firmware comparison prevents a package-compatible part from being treated as an electrically or software-compatible replacement without evidence.

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.

MC9S08RD60DWE - 8-Bit 8 MHz 60 KB MCU | NXP | 28-SOIC

NXP Semiconductors MC9S08RD60DWE is an 8-bit S08 microcontroller operating at 8 MHz, with 60 KB of flash memory and a 28-pin SOIC package. It combines a compact embedded-control footprint with 60,000 bytes of program storage, making it suitable for cost-sensitive embedded products that need readable peripheral control and deterministic firmware execution. Distributor records identify the device as the lead-free 28-SOIC AQUILA configuration, but detailed electrical limits, RAM capacity, timer resources, and pin assignments must be confirmed in the manufacturer datasheet before a hardware release. A microcontroller is a programmable semiconductor that integrates a processor core, nonvolatile program memory, data memory, and peripherals such as GPIO, timers, serial interfaces, and interrupt logic. The S08 architecture sits within the broader 8-bit microcontroller hierarchy: MC9S08RD60DWE combines an MCU with embedded flash memory and a surface-mount package. Compared with higher-bit microcontrollers, an 8-bit architecture generally emphasizes simple control logic, efficient event handling, and a compact instruction set rather than high-throughput computation or complex memory-intensive workloads. The defining verified specifications are the 8-bit CPU class, 8 MHz maximum stated frequency, and 60 KB flash organization. Flash retains program code when power is removed and supports field-programmable embedded systems. The 28-SOIC package offers a familiar leaded surface-mount format that is mechanically straightforward for production assembly. The product is described by distributors as lead-free, but comprehensive RoHS, REACH, halogen-free, and conflict-minerals declarations were not present in the supplied evidence and therefore remain unverified here. MC9S08RD60DWE belongs to the S08 RD/AQUILA product family and is positioned for embedded appliances, simple control panels, instrumentation, keypad interfaces, actuator controllers, and small motor-control systems. Firmware requirements should be checked against the available RAM, peripherals, clock options, timers, communication ports, and pin multiplexing in the datasheet. Existing code also needs source- and binary-level review because a 28-pin package match alone does not establish software compatibility. Power design begins with the manufacturer's absolute maximum and recommended operating limits, which were not included in the supplied search excerpts. Validate supply voltage, I/O levels, clock tolerances, decoupling requirements, and reset behavior against the official documentation. The 8 MHz core can reduce execution time compared with slower 8-bit designs, but actual response time depends on firmware, bus timing, peripheral configuration, interrupt latency, and whether the system operates continuously or uses low-power modes. This product page combines verified distributor specifications, sourcing links, a downloadable datasheet pointer, application guidance, and drop-in alternative screening. Because no complete manufacturer datasheet extract was supplied, unavailable electrical, environmental, timing, memory, and pin-level values are deliberately marked for verification rather than estimated. Prototype engineers should also download the NXP datasheet and confirm programming-tool, debugger, and software-library support for the complete device variant.

Its 8-bit architecture is suited to embedded control rather than high-throughput computing, while its integrated peripherals reduce the number of external components required in a control board. Key verified specifications include an 8 MHz maximum operating frequency, 16 KB of Flash program memory, 8-bit processing, SCI connectivity, PWM, watchdog timer, low-voltage detection, power-on reset, and 39 I/O pins according to the product listing snippet. The supplied sources also identify the package as 44-LQFP, 10 x 10 mm. Detailed electrical limits, RAM specifications beyond the available 1K x 8 listing, and operating temperature data must be confirmed against the manufacturer datasheet before design release. The MC9S08RE16FGE can be used for industrial control modules, motor-control peripherals, instrumentation interfaces, appliance controllers, and compact embedded systems. Its SCI interface supports serial communication with sensors, hosts, or programming equipment, while PWM and general-purpose I/O support timing and actuator-control functions. The 44-LQFP package provides a practical footprint for through-hole-compatible assembly and automated manufacturing, but careful PCB layout is still required for power, ground, decoupling, and signal integrity. The obsolete lifecycle status means engineers should verify availability before starting a new production design. Existing equipment may still use this MCU, but future redesigns should compare current S08 alternatives, confirm firmware compatibility, and validate electrical and timing requirements rather than assuming that a different package or memory organization is interchangeable. This page consolidates verified distributor data, application guidance, packaging information, and engineering considerations for MC9S08RE16FGE. It does not invent missing electrical limits, pin names, pricing, or cross-references; unavailable details are explicitly marked for engineering verification.
