MC9S08RC8FG - 8MHz 8KB 8-Bit MCU | Motorola | Embedded
部品番号: MC9S08RC8FG ✗ 生産終了MC9S08RC8FG 概要
A microcontroller is a programmable semiconductor that integrates a processor core, memory, and peripherals into one device. Within the product hierarchy, the MC9S08RC8FG is an embedded microcontroller, an 8-bit microcontroller, and specifically an S08 family device. The S08 core uses a CISC architecture and provides a direct software-driven path to compact embedded-control designs. As an 8-bit MCU, it is better suited to sequential control, sensing, and interface logic than to workloads requiring large memory capacity or high arithmetic throughput.
The principal verified features are an 8 MHz S08 processor, 8 KB of flash memory, 8K x 8 memory organization, 2.5 V or 3.3 V operation, and a 44-LQFP package measuring 10 x 10 mm. These specifications make the MC9S08RC8FG appropriate for industrial control panels, compact instrumentation, appliance controllers, data-acquisition modules, and embedded peripheral controllers. The flash-memory configuration allows firmware to be programmed into the same package used in production without an external program-memory device.
The 44-LQFP package provides 44 external connection points on a 10 x 10 mm footprint, making it useful for designs that require more I/O than a small-outline package can offer. The verified snippets do not state the complete peripheral list, RAM capacity, GPIO count, timer configuration, communication interfaces, temperature range, or electrical timing limits; these values must therefore be confirmed in the manufacturer datasheet before schematic capture or PCB release.
MC9S08RC8FG is best used as a cost-conscious embedded controller when its S08 architecture, 8 KB flash budget, and 44-LQFP footprint fit the design. Engineers should verify the complete pin assignment and peripheral map against the applicable Motorola datasheet, especially when replacing a device with a different package code or temperature-grade suffix. The complete pinout was not exposed in the supplied search results, so this record does not infer individual pin names.
This page consolidates the verified manufacturer and distributor facts, distinguishes direct family alternatives from unsupported cross-brand substitutions, and highlights the engineering details that still require datasheet confirmation before a production design is approved.

主な用途
MC9S08RC8FG の用途: 6 件s: Industrial Control Panel, Appliance Controller, Data Acquisition Module, Battery-Powered Sensor Node, Communication Interface Module, Test and Measurement Front End.
Industrial Control Panel
The MC9S08RC8FG fits a compact industrial control panel that coordinates switch states, indicators, interlocks, and simple sensor inputs. Its verified 8 MHz S08 core provides deterministic sequential processing, while 8 KB of flash supports a focused control application without requiring an external memory device. The 44-LQFP (10 x 10 mm) package preserves access to up to 44 connection points on a relatively small board. Before schematic capture, verify GPIO availability, timer channels, communication interfaces, and electrical limits in the MC9S08RC8 datasheet because those details were not present in the supplied snippets.
Appliance Controller
The MC9S08RC8FG is suitable for an appliance controller responsible for user-interface inputs, operating-state logic, and control of relays, indicators, or actuator signals. Its 8 KB flash budget can hold a compact embedded program, while the 8 MHz S08 processor supports routine debouncing, sequencing, and supervisory tasks. The 44-LQFP package offers enough external connections for multiple control signals while maintaining a compact 10 x 10 mm footprint. The final design must confirm the required GPIO count, ADC functions, timers, and operating-temperature grade directly against the manufacturer documentation.
Data Acquisition Module
The MC9S08RC8FG can serve as the local controller in a compact data-acquisition module that samples available sensor channels, conditions switch states, and forwards results over a supported serial interface. The verified 8 MHz processing rate and 8 KB flash capacity are appropriate for lightweight acquisition and protocol handling rather than high-volume signal processing. Its 44-LQFP footprint provides a practical density for mixed analog and digital connections. Engineers should first verify ADC resolution, sampling capabilities, serial-interface options, and pin multiplexing because those specifications are not confirmed by the supplied distributor excerpts.
Battery-Powered Sensor Node
The MC9S08RC8FG is suitable for a low-power sensor node when the design is built around an S08-compatible sensor interface and modest firmware requirements. The verified 2.5 V or 3.3 V operating options permit integration with compatible low-voltage power rails, while 8 KB of flash provides sufficient storage for compact sensing, sleep-state logic, and status reporting. The 44-LQFP package permits a compact implementation with more signal access than a very small microcontroller package. Verify low-power modes, wake-up sources, ADC performance, and peripheral pin assignments in the datasheet before estimating battery life.
Communication Interface Module
The MC9S08RC8FG can act as the supervisory controller in a communications or protocol-conversion module when its available serial peripherals satisfy the design requirements. The 8 MHz S08 core is suitable for framing, address handling, status monitoring, and low-rate data transactions, and 8 KB of flash permits a focused protocol stack. Its 44-LQFP package provides a practical pin count for a host interface and auxiliary controls. The verified excerpts do not identify UART, SPI, or I2C availability, so no specific interface should be assigned until the complete peripheral map and pin multiplexing are checked.
Test and Measurement Front End
The MC9S08RC8FG can control instrument front-end logic such as range selection, trigger coordination, status LEDs, and communications with a measurement engine. Its verified 8 MHz S08 core and 8 KB flash are adequate for supervisory firmware, while the compact 44-LQFP package helps preserve instrument-panel space. The controller can manage discrete I/O and timing functions when its timer and interrupt resources meet the application requirements. Before selecting it for precision measurement, confirm ADC characteristics, timer resolution, reference-voltage options, input impedance, and calibration support in the manufacturer datasheet.

主な差別化要因
- Exact verified 8 KB memory configuration （vs MC9S08RC16)

- Lower flash footprint than the larger same-family device （vs MC9S08RC32)
設計ノート
Assign the PCB footprint only after checking the exact 44-LQFP (10 x 10 mm) package drawing associated with MC9S08RC8FG. Verify pin 1 orientation, pin numbering, courtyard dimensions, solder-mask clearance, and paste-land geometry against the manufacturer drawing. Do not derive a footprint from the similar MC9S08RC16 or MC9S08RC32 packages because memory-related family variants can still differ in pin multiplexing or exposed connections.
The verified listings identify 2.5 V and 3.3 V operation, but they do not provide current consumption, voltage tolerances, internal regulator details, or power-pin requirements. Before power-tree design, obtain the MC9S08RC8 datasheet and confirm which voltage combinations apply to the core and I/O, whether external decoupling values are specified, and the sequencing limits for VDD and other supply pins. Add the required local bypass capacitors according to those verified guidelines rather than generic assumptions.
Do not treat the target as a universal software replacement for another 8-bit MCU. Although the MC9S08RC16 and MC9S08RC32 are same-family candidates with more flash, their larger memory and possible package or peripheral differences require source, linker, boot-code, and pinout reviews. For MC9S08RC8 substitutions, also confirm the package code, temperature grade, mask revision, and orderable suffix so that the replacement matches the original bill of materials.
Reserve the programming and debug connections required by the S08 device before committing the board layout, and route them away from switching nodes and high-current actuator outputs. The supplied excerpts do not identify the programming pins or communication interface, so their locations must come from the official pinout. Preserve accessible test points and avoid long traces between sensitive analog-capable pins and switching circuitry until the device's pin-multiplexing and application guidance are confirmed.
コンプライアンス情報
The supplied verified search results do not state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status. Each field remains unknown rather than being inferred from the manufacturer or package.
