MC9S08SH4CTG - 8-bit S08 MCU 4KB Flash 40MHz 16-TSSOP | NXP
MPN: MC9S08SH4CTG ✗ Cuối đờiMC9S08SH4CTG Tóm tắt
An 8-bit microcontroller (MCU) is a small computer-on-a-chip that integrates an 8-bit CPU core, non-volatile program memory, working RAM, and peripherals such as timers, communication interfaces, and analog converters. Within the semiconductor hierarchy, MCUs sit under microcontrollers, then embedded processors, then logic/semiconductor ICs. The S08 family specifically uses an enhanced HCS08 instruction set with the BGND (background debug) instruction added for in-circuit debug.
Key features include 4 KB flash, 256 B RAM, a 12-channel 10-bit ADC with 2.5 µs conversion time, an analog comparator, an internal temperature sensor, plus SCI, SPI, and I²C communication interfaces. The device supports up to 32 interrupt/reset sources and offers 13 GPIO pins. Operating voltage spans 2.7 V to 5.5 V, suiting 3.3 V and 5 V designs.
Architecturally, the MC9S08SH4CTG uses a CISC HCS08 core with a 20 MHz internal bus, achieving 40 MHz CPU throughput, plus on-chip debug and a single-wire background debug mode. It is pin, tool, and software compatible with the S08SG family, easing code migration.
Typical applications include low-end consumer appliances, white goods control boards, simple sensor nodes, industrial 5 V control logic, automotive body controllers (where an AEC-Q100 equivalent such as MC9S08SH4CFK is preferred), and battery-powered handheld devices.
When designing with this MCU, budget for the internal bus at 20 MHz and verify the 16-pin TSSOP thermal envelope at sustained 40 MHz operation. For new designs consider migrating to the active S08SH4/8 variants in 20-pin TSSOP for additional GPIO.
This page synthesizes distributor pricing, drop-in alternatives from the S08SH family, and practical design notes that complement the manufacturer datasheet for engineers evaluating the MC9S08SH4CTG.

Ứng dụng tiêu biểu
MC9S08SH4CTG phù hợp cho 6 Áp dụngs: Low-End Consumer Appliance Control, White Goods Control Boards, Industrial 5 V Sensor Node, Simple Battery-Powered Handheld, Automotive Body Controller Auxiliary, Remote Control and IR Transmitter.
Low-End Consumer Appliance Control
The MC9S08SH4CTG's 4 KB flash, 12-channel 10-bit ADC, and 5 V operation make it a cost-effective controller for consumer appliances. With its 256 B RAM supporting state-machine logic for simple control loops, the MCU handles relay drivers, user I/O, and basic sensor reads. Operating at 40 MHz CPU speed, it can service keypad scanning and LED multiplexing without an RTOS, while the on-chip SCI enables status reporting to a master display board.

White Goods Control Boards
Washing machines, dryers, and dishwashers benefit from the MC9S08SH4CTG's 2.7 V to 5.5 V supply tolerance, internal temperature sensor, and analog comparator. The 12-bit ADC accuracy is sufficient for thermistor-based water-temperature sensing, while the SCI enables communication with an inverter or display module. Drop-in compatibility with the S08SG family lets manufacturers reuse firmware across product tiers.
Được đề xuất
Industrial 5 V Sensor Node
The MC9S08SH4CTG's 5 V I/O tolerance removes the need for external level shifters when interfacing legacy industrial sensors. The 12-channel ADC supports multi-sensor acquisition (pressure, flow, temperature), while the I²C and SPI peripherals connect to digital sensors and EEPROMs. With 40 MHz CPU throughput, the MCU can run a Modbus slave over SCI for SCADA integration in factory automation.
Được đề xuất
Simple Battery-Powered Handheld
The MC9S08SH4CTG's low-power HCS08 core, internal temperature sensor, and 2.7 V minimum supply let it run from two AA cells. The integrated ADC supports battery voltage monitoring, while stop-mode current and the internal 1 kHz low-power oscillator minimize quiescent drain. Its 16-pin TSSOP footprint keeps the BOM compact for handheld thermometers, IR remotes, and simple measurement tools.
Được đề xuất
Automotive Body Controller Auxiliary
For non-safety automotive body functions such as interior lighting or seat-position memories, the MC9S08SH4CTG provides sufficient GPIO and SCI/SPI connectivity. While the standard CTG part is NRND rather than AEC-Q100 qualified, designers may evaluate the S08SH automotive variants for non-safety body modules. The 12-channel ADC reads multiple switch inputs, and the analog comparator detects voltage thresholds.
Được đề xuất
Remote Control and IR Transmitter
The MC9S08SH4CTG's SCI module supports infrared modulation directly, enabling IR remote-control applications. Its low pin count (13 GPIO) suits minimalist transmitters, while the 4 KB flash holds extensive key-code tables. The integrated temperature sensor can compensate IR LED characteristics over temperature, and the HCS08 BGND instruction simplifies in-circuit firmware development for consumer remote designs.

Ghi chú thiết kế
The MC9S08SH4CTG accepts 2.7 V to 5.5 V on VDD (pin 6). Decouple VDD with a 100 nF ceramic capacitor placed within 5 mm of the pin, plus a 10 µF bulk capacitor on the supply rail. For battery-powered applications, route the internal 1 kHz low-power oscillator to the system clock in stop mode to minimize quiescent current.
Place the BKGD/MS pin (pin 15) trace away from high-frequency switching nodes. The single-wire background debug interface is sensitive to capacitive loading above 50 pF; keep the trace under 50 mm and avoid passing it under signal traces. For production boards, add a 4.7 kΩ pull-up on RESET (pin 16).
Do not assume the SCI pins (PTC0/PTC1) are 5 V tolerant when the MCU is powered at 3.3 V - they are limited by VDD. Also note that the 12-channel ADC has a 2.5 µs conversion time, which limits sampled bandwidth to ~400 kS/s; do not exceed this for accurate conversions. The internal temperature sensor requires calibration constants stored in flash for accurate readings.
