KC9S08QG8CFFE 概要
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory (Flash/ROM), working memory (RAM), and peripheral set into one package. Within the broader hierarchy, the KC9S08QG8CFFE is a low-pin-count 8-bit MCU -> HCS08 family -> S08QG sub-family -> 8-bit microcontroller -> embedded processor -> semiconductor. The HCS08 core uses the S08 instruction set (a superset of the legacy HC05/HCS05 family), enabling object-code reuse from earlier Freescale 5V 8-bit designs. Synonyms frequently seen on datasheets and distributor pages include HCS08 MCU, S08 microcontroller, and QG-series small-package 8-bit MCU.
Key features of the KC9S08QG8CFFE include 8KB of Flash program memory, multiple low-power modes for battery-friendly operation, on-chip debug support via the Freescale/NXP background debug mode (BDM), and an integrated peripheral set that typically covers timers, ADC, GPIO, and a serial communications interface (SCI/SPI). The device operates across an industrial temperature range and is designed for cost-sensitive, low-power, low-pin-count embedded applications. The 'KC' prefix designates Rochester Electronics' authorized aftermarket re-stocking of the discontinued Freescale/NXP original part number, ensuring long-term availability for legacy designs.
From a technical depth perspective, the S08QG family uses a von Neumann architecture with a 16-bit address space, enabling efficient C and assembly code generation. The Flash memory supports in-application programming (IAP) and in-circuit programming (ICP), which simplifies firmware development and field upgrades. Internal clock sources and PLL options allow flexible system-clock configuration while minimizing external component count, which is critical for the small-package target footprint.
Typical applications for this part include small consumer appliances, low-cost remote controls, battery-powered sensor nodes, white-goods user-interface controllers, and replacement/aftermarket boards for industrial equipment originally built around Freescale S08QG designs. The combination of low power, small package, and integrated peripherals makes it well suited to designs where board space, BOM cost, and energy budget matter more than raw CPU throughput.
When designing with the KC9S08QG8CFFE, engineers should verify the active lifecycle status with the supplier because the original Freescale/NXP part was moved to End of Life; Rochester Electronics is the primary authorized stock source. Pinout, peripheral mapping, and Flash programming voltages must be cross-checked against the original NXP MC9S08QG8 datasheet family document, which the Rochester part replicates.
This page synthesizes distributor pricing snapshots, lifecycle signals, drop-in same-family alternatives, and practical sourcing notes not consolidated in the original NXP datasheet alone.

主な用途
KC9S08QG8CFFE の用途: 6 件s: Low-Cost Consumer Appliance Control, Battery-Powered Sensor Node, Remote Control and HMI Keypad, Industrial Control Aftermarket Board, White-Goods User Interface Module, Educational and Hobby Microcontroller Board.
Low-Cost Consumer Appliance Control
The KC9S08QG8CFFE fits low-cost consumer appliance controllers - coffee makers, blenders, washing-machine user-interface boards, and small kitchen gadgets - because the S08QG's 8KB Flash and HCS08 core are sized for typical motor-control or user-interface firmware while the small QG package keeps the BOM and board area minimal. With internal clock options, designers can drop the external crystal on cost-sensitive SKUs and still meet timing budgets for relay sequencing and sensor sampling. Compared with newer Cortex-M0 alternatives, the KC9S08QG8CFFE offers proven toolchain maturity and lower unit cost for high-volume appliance runs.
おすすめ
Battery-Powered Sensor Node
For battery-powered remote sensor nodes, the KC9S08QG8CFFE provides the S08QG family's low-power stop and wait modes that extend battery life into multi-year ranges, with 8KB Flash sufficient for sensor calibration tables and protocol stacks. The integrated ADC and timers handle periodic wake-and-measure cycles without external glue logic, and the BDM debug interface simplifies field firmware updates via ISP. The part's industrial temperature range supports outdoor or industrial-cabinet deployments where temperature swings are common.
おすすめ
Remote Control and HMI Keypad
The KC9S08QG8CFFE suits TV remote controls, garage-door openers, and small human-machine-interface keypads because the HCS08 core, GPIO count, and SCI peripheral cover IR-LED modulation or keypad scanning with no external components beyond the keypad matrix. The 8KB Flash holds protocol code for RC5, NEC, or proprietary IR formats plus state-machine firmware, and the small package allows a slim remote enclosure. Its low active current and deep-sleep modes keep AAA-cell remote controls running for years on a single battery set.
おすすめ
Industrial Control Aftermarket Board
The KC9S08QG8CFFE, as Rochester Electronics' authorized re-stock of the discontinued Freescale original, is the go-to choice for repairing or re-manufacturing industrial control boards originally designed around the S08QG family. PLC I/O modules, conveyor controllers, and HVAC actuator boards that shipped with the MC9S08QG8CFFE can be serviced without re-qualification when KC-prefixed stock is used. This makes the part especially valuable for legacy industrial systems with 10-20 year service lifetimes where redesign is impractical.
おすすめ
White-Goods User Interface Module
Dishwasher, washer-dryer, and oven user-interface modules benefit from the KC9S08QG8CFFE's combination of small package, integrated timers, and sufficient Flash for multi-segment LCD or LED display driving. The HCS08 core handles button-debounce, display refresh, and serial communication to the main appliance controller with low latency. Because the part is EOL but still serviceable through Rochester Electronics, white-goods OEMs can extend the support window for installed appliance populations without re-spinning the UI board.
おすすめ
Educational and Hobby Microcontroller Board
The KC9S08QG8CFFE appears in older educational microcontroller boards and hobby electronics kits because the Freescale/NXP S08 family has publicly available application notes, sample code, and BDM tool support at low cost. Students learning 8-bit embedded design benefit from the S08 instruction set's clarity and the availability of CodeWarrior for S08 toolchain. For new designs, learners typically migrate to the FRDM-KL25Z or similar ARM-based boards, but the KC9S08QG8CFFE remains in use for legacy course materials and repair of existing kits.

主な差別化要因
- Authorized Rochester Electronics aftermarket stock （vs MC9S08QG8CFFE (original NXP/Freescale MPN))
- Same 8KB Flash footprint as the original （vs MC9S08QG4CFFE (4KB Flash variant))
- HCS08 core compatibility for code reuse （vs Generic 8051 or PIC alternatives)
設計ノート
Because the original Freescale/NXP part is End of Life, design teams must explicitly plan for long-term supply. Rochester Electronics is the authorized aftermarket source and the only recommended channel - avoid independent brokers unless you can validate traceability, because counterfeit Freescale/NXP S08QG stock has been reported in the secondary market. For high-volume or long-life programs, place a lifetime-buy order with Rochester before existing stock is exhausted.
The S08QG family supports multiple low-power modes (stop, wait, and run). To minimize quiescent current in battery-powered designs, configure unused peripherals to their lowest-power state and use the ADC or pin-wake interrupt to exit stop mode. Estimated: a typical S08QG in stop mode draws single-digit microampere current, but always measure on your specific board because peripheral leakage paths through GPIO can dominate.
For QFN/QFP small-package variants of the KC9S08QG8CFFE, provide a continuous ground plane under the package and stitch vias around the perimeter for thermal dissipation and EMI suppression. Decouple VDD with a 100nF ceramic capacitor placed within 5mm of the supply pin, and add a bulk capacitor (1uF to 10uF) near the regulator output. The BDM interface requires a dedicated 6-pin or 10-pin header for in-circuit programming - do not share these pins with application circuitry.
コンプライアンス情報
RoHS and lead-free compliance per the Bangyanchip listing of the Rochester Electronics LLC authorized stock. Original Freescale/NXP part was EOL'd; Rochester's KC-prefixed aftermarket stock replicates the original environmental compliance profile. AEC-Q100 not applicable - this is a general-purpose 8-bit MCU, not an automotive-qualified part.
