SC9S08QG8TCDTER 概要
What is an 8-bit microcontroller? An 8-bit MCU is a small, self-contained computer-on-a-chip that executes instructions on 8-bit-wide data paths. It belongs to the broader category of microcontrollers -> embedded microcontrollers -> microprocessors -> semiconductors. The S08QG family specifically sits at the low-cost, low-power end of NXP's HCS08 lineup, offering S08 CPU performance with peripheral integration to minimize external component count.
Key features include 8KB Flash for program storage, an HC08/S08 CPU core, multiple GPIO lines, timers, and an on-chip analog-to-digital converter. The TSSOP-16 footprint makes the part well-suited for compact PCB layouts where board area is at a premium. Internal peripherals and a flexible clock source further reduce external part count.
The architecture follows the HCS08 instruction set, with an enhanced S08 core that improves performance over the legacy HC08 while preserving code compatibility. On-chip debug and Flash programming support accelerate development cycles, and the wide operating voltage range enables battery-powered as well as line-powered designs. The SC9S08QG8TCDTER is supplied in 16-pin thin-shrink small-outline package (TSSOP-16), a thin-profile surface-mount option that balances board density with hand-rework ease.
Typical applications include consumer electronics remote controls, small sensor hubs, home-appliance user-interface controllers, low-end toy and hobby electronics, and battery-powered handheld devices. The small Flash footprint and modest RAM resources make it a natural fit for applications with fixed-function firmware rather than user-upgradable software.
Designers should plan firmware size carefully within the 8KB Flash budget and verify that peripheral usage matches the pin-out of the TSSOP-16 package. A robust decoupling network and a clean clock source are essential to maintain MCU timing accuracy in noise-sensitive applications.

主な用途
SC9S08QG8TCDTER の用途: 7 件s: Consumer Remote Control, Home Appliance User Interface, Battery-Powered Sensor Node, Toy and Hobby Electronics, LED Lighting Controller, Industrial Sensor Interface, Small Motor Control (BLDC/Fan).
Consumer Remote Control
The SC9S08QG8TCDTER is well suited for handheld IR/RF remote controls thanks to its 8KB Flash budget, low pin count, and TSSOP-16 surface-mount package. In a typical remote, the MCU reads a key matrix, encodes IR or RF commands, and manages battery-conserving sleep modes between button presses. The 8-bit S08 instruction set is sufficient for fixed-function remote firmware, while the TSSOP-16 keeps the PCB footprint small enough to fit beneath a keypad. Compared to 32-bit Cortex-M0 alternatives, the SC9S08QG8TCDTER reduces BOM cost at the expense of processing headroom, which is acceptable because remotes rarely need more than GPIO scanning and a transmit timer.
おすすめ
Home Appliance User Interface
In washing machines, microwave ovens, and small kitchen appliances, the SC9S08QG8TCDTER can drive LED or seven-segment displays, scan keypad input, and control relays or triacs for load switching. The on-chip peripherals reduce external component count, and the TSSOP-16 package is small enough for tight control boards. The 8KB Flash covers typical UI state machines including timing, fault detection, and indicator control. Designers should budget for debounce routines and zero-crossing detection in firmware, and use optocouplers or gate drivers for mains isolation.
おすすめ
Battery-Powered Sensor Node
Wireless sensor endpoints for temperature, humidity, or occupancy monitoring can use the SC9S08QG8TCDTER as a low-cost MCU that wakes periodically, reads a sensor over GPIO or bit-banged I2C, and transmits results via a paired RF transceiver. The 8KB Flash is enough for simple sensor-fusion and transmission state machines. Battery life is dominated by the sleep-mode current of the MCU and the RF transmit duty cycle, so designers should use the S08's wait/stop modes between samples and gate power to the radio. The TSSOP-16 footprint fits in coin-cell sensor PCBs.
おすすめ
Toy and Hobby Electronics
Cost-sensitive toys, educational electronics kits, and hobby controllers fit the SC9S08QG8TCDTER profile: small footprint, simple peripherals, 8KB of Flash for behavior trees or state-machine code, and a sub-$2 unit cost at volume. The MCU can interface with hobby servos over GPIO bit-banging or a simple timer PWM, drive LEDs and small motors via MOSFETs, and read analog sensors through the on-chip ADC. The TSSOP-16 package allows hand-solderable builds for hobbyists. Volume pricing drops below $1 at qty-1000 per current distributor tiers.
おすすめ
LED Lighting Controller
Addressable LED strip drivers and decorative lighting controllers can use the SC9S08QG8TCDTER to generate WS2812/SK6812 timing protocols via bit-banged GPIO or PWM+DMA techniques. The 8KB Flash fits color-pattern libraries and animation state machines. The TSSOP-16 keeps controller boards compact for inline strip drivers, and the wide supply range enables direct 5V or 12V operation with a small LDO. Each LED driver board typically uses one SC9S08QG8TCDTER driving 100-300 addressable LEDs at modest refresh rates.
おすすめ
Industrial Sensor Interface
Simple industrial sensor interface boards (4-20 mA loop-powered transmitters, thermistor conditioners, switch debouncers) can use the SC9S08QG8TCDTER as a low-cost signal-conditioning MCU. It reads analog sensors, linearizes them, and outputs a digital signal over UART, SPI, or a 4-20 mA DAC. The industrial temperature range (-40C to +85C) and TSSOP-16 surface-mount package suit small DIN-rail or panel-mount boards. Firmware should include CRC-protected communications and watchdog timers for industrial robustness.
おすすめ
Small Motor Control (BLDC/Fan)
Low-power brushless DC fan controllers and small motor drivers can use the SC9S08QG8TCDTER for commutation timing and speed-control loops. The S08's timer peripherals can drive 3-phase commutation PWM, and the 8KB Flash fits sensored or sensorless startup routines. The TSSOP-16 package keeps the controller small enough to integrate into the motor housing or a small fan driver board. Designers must add external gate drivers and MOSFETs because the MCU GPIO cannot directly drive motor windings.

設計ノート
Decouple VDD (pin 9) with a 100nF ceramic capacitor placed within 5 mm of the supply pin, and add a 10uF bulk capacitor on the same rail. The S08 core's STOP/WAIT modes drop current to microamps; gate any unused peripheral power domains to extend battery life. Estimated: at 3.3V VDD and 20 MHz bus, active current is approximately 5-8 mA per S08QG family typical characteristics.
Route the BKGD/MS line (pin 15) away from high-frequency switching traces to avoid debug-noise coupling. Keep the RESET line (pin 16) short and add an external pull-up of 10 kohm to VDD; place a 100nF cap to VSS if a tactile reset button is used. The TSSOP-16 thermal pad is not present - ensure copper pours under the part for ground stitching rather than heat spreading.
Do not exceed 8 KB of compiled Flash - firmware growth past this boundary requires migrating to a higher-density S08QG variant. The TSSOP-16 pinout reuses PTA/PTB pins for alternate peripheral functions; lock pin assignments early so peripheral reassignment does not break firmware. Pin 15 must be pulled high during reset for normal operation; floating BKGD can prevent boot.
