MC9S08SH16CTG - 8-Bit 40MHz 16KB MCU 16-TSSOP | NXP
MPN： MC9S08SH16CTG ✗ 停產MC9S08SH16CTG 概覽
A microcontroller is a programmable semiconductor that integrates a CPU, memory, and peripherals into one device. The HCS08 CPU belongs to the 8-bit MCU hierarchy and uses the HC08 instruction set, allowing efficient control of digital inputs, outputs, timers, communications, and analog signals. The MC9S08SH16CTG is positioned as an entry-level S08SH-family controller for compact industrial, automotive, appliance, and instrumentation designs.
The verified product data identifies a 40 MHz maximum clock frequency, 16 KB of Flash organized as 16K × 8, an 8-bit data-bus architecture, and a 16-TSSOP package. The MCU also supports up to 32 interrupt/reset sources according to the supplied technical description. Its integrated analog comparator and keyboard interrupt reduce the need for external circuitry in basic sensing and key-detection systems, while its flash memory supports firmware retention and field-updateable application code.
The S08SH family is intended for applications in the 5 V range and combines conventional embedded-control functions with low-cost integration. A 40 MHz CPU provides processing headroom for state machines, communication protocols, timing tasks, and peripheral coordination. The 16 KB flash capacity is appropriate for compact control firmware where code size, deterministic behavior, and rapid deployment are more important than maximum software capacity.
Typical uses include motor and relay control, appliance controllers, industrial interface modules, keyboard-equipped panels, low-cost instrumentation, and embedded automotive or industrial subsystems. For new 5 V designs, firmware and board validation should be completed carefully because the manufacturer product page identifies the part as End of Life. Designers should confirm availability, lifecycle status, and any approved successor before committing to a production release.
The most important design considerations are supply-voltage compatibility, pin-level peripheral assignment, flash programming, clock configuration, decoupling, and validation of the analog comparator. Because the device is marked End of Life, sourcing should be treated as a lifecycle-managed activity rather than a routine new-design choice. This page consolidates verified distributor and manufacturer information, practical design notes, and lifecycle considerations; detailed electrical limits and pin functions must be checked against the manufacturer datasheet.

典型應用
MC9S08SH16CTG 適用於 6 應用s: Cost-Sensitive Industrial Control, Appliance and Relay Interface, Keyboard and Panel Interface, Low-Cost Analog Threshold Sensing, Embedded Automotive Subsystem, Battery-Powered Embedded Instrument.
Cost-Sensitive Industrial Control
The MC9S08SH16CTG fits compact industrial controllers because it combines a 40 MHz 8-bit HCS08 CPU with 16 KB of Flash in a 16-TSSOP package. Its integrated analog comparator can monitor a threshold signal, while the keyboard interrupt supports local panel input without a separate dedicated controller. A typical design would place the MCU between a sensor interface and relay or actuator drivers, using its interrupt sources for responsive state changes. The 16 KB Flash budget should be checked against firmware, bootloader, calibration, and communication routines before release.
推薦
Appliance and Relay Interface
For appliance and relay-interface products, the MC9S08SH16CTG provides an 8-bit embedded-control core, 16 KB of Flash, and operation identified for the 5 V range. The controller can supervise buttons, sequence relays, monitor a comparator threshold, and manage timing without a separate processor for each function. Its 16-TSSOP package helps reduce board area, while the 40 MHz CPU allows interrupt-driven control tasks to coexist with basic communications. Firmware must include safe output defaults and validation because a relay or appliance actuator requires deterministic shutdown behavior.
推薦
Keyboard and Panel Interface
The MC9S08SH16CTG is suitable for simple keyboard-equipped panels because the verified feature list includes keyboard interrupt support. A scanning or interrupt-based keypad can be connected alongside a small display, indicator LEDs, and a low-cost control interface without relying on a larger application processor. The 40 MHz HCS08 core can debounce inputs, update state, and execute local commands, while 16 KB of Flash holds compact panel firmware. Pin multiplexing, debounce strategy, and electrical levels should be confirmed from the manufacturer pin table and datasheet before layout release.
推薦
Low-Cost Analog Threshold Sensing
The integrated analog comparator makes the MC9S08SH16TG useful for basic analog threshold monitoring, such as battery-level indication, supply monitoring, or simple sensor discrimination. The comparator can generate an interrupt or status signal while the 8-bit CPU performs control and filtering, reducing the need for a dedicated comparator IC in straightforward designs. The verified data also identifies a 12-channel, 10-bit ADC, but exact ADC routing and operating conditions require confirmation. Use resistor-divider design and input protection appropriate to the device electrical limits.
推薦
Embedded Automotive Subsystem
NXP describes the MC9S08SH16CTG as suitable for cost-sensitive industrial and automotive applications. Its integrated Flash, analog comparator, keyboard interrupt, and low-power stop modes can support simple body-control, panel, accessory, or interface functions where an 8-bit controller is sufficient. The 16-TSSOP package supports compact board construction, and the 40 MHz CPU provides timing margin for control tasks. Automotive deployment must additionally verify temperature grade, automotive qualification, electrical transients, functional safety requirements, and any manufacturer-approved replacement because the target is End of Life.
推薦
Battery-Powered Embedded Instrument
The MC9S08SH16CTG can serve as the controller in a small battery-powered instrument that wakes periodically, measures a comparator threshold, updates a display or status indicator, and returns to a low-power state. The supplied data identifies two low-power stop modes, while the 40 MHz CPU provides enough performance for short measurement and control bursts. Designers should verify actual stop-mode current, wake-up sources, and regulator requirements because those values are not included in the supplied data. Battery life should be estimated from the final duty cycle and verified on hardware rather than assumed from the microcontroller name.

設計說明
Decouple each supply pin locally with the capacitance and placement required by the manufacturer’s recommended layout. Because the verified data confirms 3.3 V and 5 V operation but does not provide complete electrical limits, do not infer the allowable voltage, I/O levels, or decoupling values from the distributor description. Confirm supply sequencing, input overvoltage tolerance, and power-source impedance in the current NXP datasheet before fabrication.
Use the 16-TSSOP footprint and preserve the manufacturer’s pin-1 orientation, exposed-pad rules, and solder-reflow profile. The verified listings identify a 16-TSSOP package measuring 4.40 mm wide, but they do not provide a complete pinout or land pattern. Cross-check the exact package drawing and pin multiplexing in the datasheet, especially for programming, reset, clock, comparator, and ADC signals.
Do not treat every S08-family part as a direct substitute. Related MPNs may differ in memory size, peripheral mapping, temperature grade, clocking, package dimensions, or lifecycle status. Before using an alternative, compare the complete pin table, electrical limits, memory map, reset behavior, programming interface, and firmware requirements. The target is End of Life, so lifecycle validation is as important as electrical matching.
For comparator or ADC-based sensing, route the analog input away from switching nodes and keep the input path short. Add protection appropriate to the sensor and verify the reference and filtering scheme in the datasheet. The verified material confirms integrated analog and 12-channel, 10-bit ADC claims, but it does not provide input impedance, acquisition time, accuracy, or reference voltage; those parameters must be obtained before setting sampling or calibration requirements.
The MC9S08SH16CTG is a microcontroller rather than a power semiconductor, so a safe-operating-area chart is not applicable. Thermal design should focus on the package power dissipation, ambient range, PCB copper area, and maximum supply conditions specified by the manufacturer. Those thermal limits are not included in the supplied data, so no junction-temperature calculation is presented here. Measure or calculate from official limits rather than estimating a safe temperature for the TSSOP package.
合規資訊
The supplied distributor and secondary listings do not provide verified RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals declarations for MC9S08SH16CTG. Obtain current compliance documentation from NXP or an authorized supplier.
