MC9S08SH16CTLR - 40MHz 16KB 8-Bit MCU | NXP | Automotive
料号： MC9S08SH16CTLR ✗ 停产MC9S08SH16CTLR 概述
A microcontroller is a programmable semiconductor that integrates a processor core, memory, digital I/O, analog conversion, communications peripherals, and debug support on one device. The MC9S08SH16CTLR belongs to the HCS08 family and its 8-bit CISC architecture provides straightforward embedded-control processing. The device supports up to 32 interrupt or reset sources, making it suitable for responsive event-driven systems.
Key features include a 40-MHz HCS08 central processing unit, 16 KB of internal flash, 1 KB of RAM, and a 10-bit analog-to-digital converter. Available communication and control resources cited by the supplied data include SCI, SPI, and IIC interfaces. A 23-I/O count supports external sensors, indicators, actuators, and control signals, while the internal oscillator eliminates a mandatory external clock source.
The MCU is used where moderate computation, memory, and serial connectivity are needed without a higher-cost processor. Its 2.7 V to 5.5 V supply range accommodates common embedded rails, and the 28-pin TSSOP package provides a board-compatible surface-mount footprint. Reported converter details vary among supplied search snippets, so channel count and conversion timing must be confirmed against the manufacturer datasheet before a safety- or timing-critical design is released.
Typical uses include automotive body and control modules, compact sensor interfaces, small motor-control boards, industrial controls, and communication hubs. Its SCI, SPI, and IIC peripherals allow connection to transceivers, sensors, memory, and other controllers without requiring several external interface devices.
Designers should preserve the 28-pin footprint, confirm every peripheral mapping against the datasheet, and include adequate decoupling and signal-integrity practices. The supplied data does not establish complete pin assignments, electrical limits, timing values, or automotive qualification status, so those items must not be inferred from generic family information.
This page consolidates the supplied manufacturer and distributor results, separates verified facts from unresolved details, and adds procurement, comparison, and design guidance not presented as a single source in the manufacturer datasheet.

典型应用
MC9S08SH16CTLR 适用于 6 应用s: Automotive Body Control Module, Industrial Sensor Interface, Compact Motor and Actuator Controller, Serial Communication Hub, Battery-Powered Embedded Instrument, Data Acquisition Front End.
Automotive Body Control Module
The MC9S08SH16CTLR fits compact automotive body-control nodes because it combines a 40 MHz 8-bit HCS08 core, 16 KB flash, 1 KB RAM, and 23 I/O pins. These resources can supervise switches, lamps, sensors, and small actuators while SCI, SPI, and IIC provide links to transceivers or external controllers. Its 28-pin TSSOP package limits board area, and the stated 2.7 V to 5.5 V range supports common embedded rails. The automotive designation still requires exact AEC-Q100, temperature-grade, traceability, and errata confirmation before production release.
推荐
Industrial Sensor Interface
The MC9S08SH16CTLR is suitable for a compact sensor-interface board that must sample analog conditions and report measurements over a short-range serial link. Its 10-bit ADC, 23 I/O pins, and SPI, IIC, or SCI options reduce the need for separate interface hardware, while 1 KB RAM supports buffering and 16 KB flash holds firmware. The internal oscillator can simplify common designs. Engineers must resolve the conflicting ADC channel information in the supplied snippets, verify conversion timing from the manufacturer datasheet, and define input protection for each external sensor.
推荐
Compact Motor and Actuator Controller
The MC9S08SH16CTLR can coordinate discrete actuators and small motors where a 40 MHz control loop and 23 I/O pins are useful but high-end processing is unnecessary. Timers, interrupts, and event-driven firmware can manage digital command signals, while SPI or IIC connects to driver and sensor ICs. The 2.7 V to 5.5 V supply range simplifies interface planning around common embedded rails. Because motor transients can exceed logic limits, external protection, isolation, grounding, and thermal review are essential; no motor-output ratings should be inferred from the MCU itself.
推荐
Serial Communication Hub
The MC9S08SH16CTLR can serve as a small protocol bridge or supervisory node when a board must combine an 8-bit controller with SCI, SPI, and IIC connectivity. Its 40 MHz maximum clock provides headroom for interrupt-driven data handling, while 16 KB flash and 1 KB RAM suit bounded protocol tasks. The internal oscillator can lower external-clock requirements, but accurate baud-rate and timing behavior still depend on clock configuration. Validate framing, timeout, bus contention, and peripheral pin multiplexing in firmware prototypes before deploying the controller as a communications hub.
推荐
Battery-Powered Embedded Instrument
The MC9S08SH16CTLR can support a compact battery-powered instrument when low voltage tolerance, modest memory, and mixed digital interfaces are more important than a high-pin-count processor. Its stated 2.7 V to 5.5 V operating range allows use near common regulated rails, while the internal oscillator can simplify low-power clocking. Power consumption, sleep behavior, analog accuracy, and wake-up time are not supplied, so engineers should measure them on the intended board. Add low-leakage regulators, controlled pullups, and load switches because the MCU itself does not guarantee system-level battery life.
推荐
Data Acquisition Front End
The MC9S08SH16CTLR is applicable to a small data-acquisition front end that converts a limited number of analog inputs and transfers results through SPI or IIC. Its 10-bit ADC resolution, up-to-40-MHz processor, and 23 I/O pins provide a compact implementation for control-oriented measurements rather than high-resolution instrumentation. Firmware can average, filter, threshold, and timestamp samples before transmission. Confirm the exact ADC channel count and sample time because supplied snippets conflict, then add input conditioning, reference design, calibration, and channel isolation appropriate to the measured signal.

设计说明
Route the 28-pin TSSOP footprint and its decoupling connections exactly from the current NXP package drawing. Place each required bypass capacitor adjacent to the corresponding power pin, keep the ground-return path short, and reserve the single-wire background-debug interface for programming access. The supplied sources identify the package and debug interface but not a complete verified pin table, so do not finalize connectivity or track widths from distributor summaries alone.
Treat SCI, SPI, and IIC as separate electrical subsystems. Match SPI routing as a short clock path with a controlled return, keep IIC traces compact and account for rise-time capacitance, and provide the pull-up values required by the bus voltage and speed. Pin multiplexing must be checked against the exact datasheet because several I/O functions can share ports. If a trace leaves the board, add the required protection, impedance, grounding, and isolation rather than assuming the MCU pins tolerate external transients.
The supplied sources are not fully consistent about RAM and ADC channels: one product-page snippet states 512 B RAM and another states 1 KB, while ADC channel excerpts mention both 12 and 16 channels. Treat 1 KB RAM and 10-bit conversion as supplied distributor facts, but do not allocate channel-specific firmware or memory-intensive tasks until the exact device revision confirms those values. Also verify the meaning of the 20 MHz bus reference versus the listed 40 MHz maximum processor frequency.
合规信息
The supplied data calls MC9S08SH16CTLR automotive-oriented but does not provide formal RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals declarations. These statuses remain unknown pending current NXP or authorized-distributor documentation.
