Designers should consider the device when total BOM cost and quiescent current dominate the decision more than raw CPU throughput. When laying out a board for this MCU, place the 0.1 uF VDD decoupling capacitor within 3 mm of the supply pin and keep the RESET pull-up trace short. Avoid routing high-current switching signals adjacent to the ADC input pins to prevent crosstalk; use the dedicated AVSS / AVDD pair if analog accuracy is required. For firmware development, CodeWarrior IDE and the PE micro / P&E Multilink debugger are the canonical tool chain.

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 Motorola MC9S08RC8CFG is an 8-bit S08 CISC microcontroller operating at up to 8MHz, with 8KB of Flash memory and a 44-pin LQFP package measuring 10mm by 10mm. The device is intended for embedded control applications requiring modest processing throughput, on-chip Flash program memory, low-voltage operation, and a compact surface-mount package. Verified distributor listings identify the part as an S08 microcontroller with an 8KB Flash configuration and an operating voltage range of 2.5V to 3.6V or 1.8V to 3.6V depending on the source listing; engineers should confirm the exact electrical limits against the manufacturer datasheet before design release. A microcontroller is a programmable control component that integrates a CPU core, memory, and peripherals on one semiconductor device. The S08 family belongs to the broader embedded-controller hierarchy and is designed for compact control systems rather than high-performance computing. MC9S08RC8CFG combines an 8MHz maximum clock with 8KB Flash, making it appropriate for products that require moderate real-time control, local program storage, and a low component count without an external memory interface. The verified specifications identify the MCU as an 8-bit S08 device with 8KB Flash and a 44-LQFP package. The S08 architecture uses a CISC-style instruction set and is suited to embedded products requiring straightforward firmware control, GPIO handling, timers, serial communication, and analog or control functions, subject to the exact peripheral configuration in the manufacturer datasheet. 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

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.

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.

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.

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.

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.
