MC9S08RE16FJ - 8-Bit 8MHz 16KB Flash MCU | NXP
MPN: MC9S08RE16FJ ✗ پایان تولیدMC9S08RE16FJ نمای کلی
A microcontroller is a programmable semiconductor integrating a CPU, memory, and peripherals on one device. The S08 architecture belongs to the broader embedded-controller hierarchy: 8-bit microcontroller, embedded processor, and programmable logic device. By executing firmware stored in its internal Flash memory, the MC9S08RE16FJ can read inputs, run control algorithms, and drive outputs without a separate external processor. Its compact package also reduces board area compared with larger general-purpose microcontrollers.
The principal operating characteristics include an 8-bit architecture, an 8 MHz maximum clock, 16 KB of Flash program memory, and a 1.8 V to 3.6 V supply range. The 32-LQFP (7 x 7 mm) surface-mount package supports compact PCB layouts while providing external connections for power, clock, programming, reset, and peripheral functions. These characteristics make the device suitable for embedded controllers where deterministic control, modest memory requirements, and low system complexity are more important than high computational throughput.
The S08 RE family is positioned for general embedded control rather than high-performance or highly connected applications. Its 8-bit processing model can handle motor and relay sequencing, key scanning, sensor conditioning, simple communications, and autonomous product logic. The 16 KB Flash capacity provides room for application firmware, while the S08 instruction set and peripheral integration help minimize external logic. Designers should confirm the complete peripheral list, RAM capacity, clocking options, and programming requirements in the manufacturer datasheet before finalizing a design.
Typical uses include appliance controllers, compact sensor modules, industrial control panels, building equipment, battery-operated products, and small automation controllers. In these systems, the microcontroller can consolidate several discrete functions into one firmware-driven device. For example, it can acquire sensor information, apply threshold logic, manage operator inputs, and control actuators while occupying only a small portion of a densely populated board.
The primary design consideration is matching the controller's electrical limits and pin functions to the intended system. Use the package drawing and pin-description table in the manufacturer datasheet when assigning tracks and programming connectors. Decoupling, programming-header access, clock stability, reset handling, and exposed-pad or thermal-layout requirements should be reviewed before schematic release. Firmware development also depends on the correct S08 programming method and toolchain for the production workflow.
This page organizes the documented MC9S08RE16FJ specifications, sourcing information, comparison fields, and practical design guidance. It also distinguishes verified drop-in replacements from broader S08 devices, helping engineers make a replacement decision without assuming that a similar memory size or architecture guarantees PCB compatibility.

کاربردهای معمول
MC9S08RE16FJ مناسب است برای 6 کاربردs: Appliance Control, Industrial Sensor Module, Building Equipment Controller, Battery-Operated Product, Compact Operator Panel, Small Automation Controller.
Appliance Control
The MC9S08RE16FJ fits compact appliance controllers because its 8-bit S08 core can run sequencing and state-machine logic while 16 KB of Flash stores application firmware on the device. Operating from 1.8 V to 3.6 V supports regulated low-voltage designs, and the 32-LQFP package limits board area. It can manage user inputs, sensors, relays, and actuator outputs, although the designer must confirm the exact timer, I/O, and communication functions required by the appliance before schematic release.
پیشنهادی
Industrial Sensor Module
An 8 MHz S08 processor is appropriate for a small sensor module that must acquire measurements, apply filtering and threshold logic, and report status locally. The MC9S08RE16FJ provides 16 KB of onboard Flash for firmware and uses a 32-LQFP footprint that supports dense instrumentation boards. Its 1.8 V to 3.6 V operating range fits low-voltage sensor platforms. Verify analog-converter resources, communication interfaces, timer accuracy, and the required environmental temperature range before selecting it for a specific sensor interface.
پیشنهادی
Building Equipment Controller
The MC9S08RE16FJ can serve as the low-cost controller in building equipment that coordinates switches, sensors, timing functions, and simple status indicators. Its 8-bit architecture and 8 MHz clock are sufficient for deterministic supervisory tasks, while the 16 KB Flash capacity allows application code, calibration tables, and operating-state logic to remain onboard. The 32-LQFP package supports compact control boards, but deployment conditions must be checked against the datasheet's temperature, electrical, and communication requirements.
پیشنهادی
Battery-Operated Product
The 1.8 V to 3.6 V supply range makes the MC9S08RE16FJ relevant to battery-operated products that use regulated power and require local autonomous control. Its 8-bit core can execute low-duty-cycle state machines, monitor inputs, and operate actuators without continuous high-performance processing. Onboard 16 KB Flash avoids a separate program-memory device for compact firmware. Power consumption, sleep behavior, wakeup sources, and battery-life implications must be evaluated from the manufacturer datasheet and the complete peripheral configuration.
پیشنهادی
Compact Operator Panel
The MC9S08RE16FJ can manage a compact operator panel that combines switch or keypad inputs with LEDs, local displays, and status logic. An 8-bit S08 controller at up to 8 MHz can scan inputs and update outputs, while 16 KB of Flash holds interface firmware and configuration behavior. The 32-LQFP package provides a relatively compact solution compared with larger leaded controllers. Verify the required display interface, debounce resources, update timing, and external driver count in the manufacturer datasheet before layout approval.
پیشنهادی
Small Automation Controller
The MC9S08RE16FJ is suited to small automation controllers that coordinate sensor inputs, counters, safety interlocks, and actuator outputs. Its 8-bit architecture handles straightforward control algorithms efficiently, while 8 MHz operation supports responsive multitasking or interrupt-driven routines. The 16 KB Flash capacity can hold sequence logic and configuration tables, and the 32-LQFP package keeps the controller compact. For machinery applications, confirm watchdog, fault-output, isolation, timing, and environmental requirements before using it in a safety-related control path.

یادداشت‌های طراحی
Use the manufacturer datasheet's 32-LQFP land pattern rather than drawing the footprint from the package dimensions alone. Place decoupling capacitors close to the supply and ground terminals, keep the programming connector accessible, and route high-current outputs away from sensitive input traces. Confirm the exposed-pad connection and assembly requirements from the package drawing before releasing the PCB.
Design the 1.8 V to 3.6 V supply so it remains within all operating and I/O conditions of the MC9S08RE16FJ. Check the datasheet for voltage thresholds, output-driver limits, and current behavior because a nominal 3.3 V rail alone does not establish compatibility with every attached peripheral. Provide local bulk and high-frequency decoupling and verify startup behavior in the final power topology.
Do not treat another S08-family member as a footprint-compatible replacement without checking every pin. The MC9S08RE16FJ uses a 32-LQFP (7 x 7 mm) package, while other family variants may use different pin counts, package dimensions, peripheral assignments, or memory configurations. Review the pin-description table, memory map, clock setup, programming method, and interrupt assignments for any proposed substitution.
Keep oscillator, reset, and programming-related routes short and away from noisy switching nodes. Although the controller operates at up to 8 MHz, poor return paths, floating inputs, or unstable supply references can still cause unreliable behavior. Follow the recommended application circuit in the manufacturer datasheet for bypass components and grounding, and test signal integrity with the intended external peripherals connected.
Estimated: at a 3.3 V supply and 10 mA average operating current, the calculated supply power is approximately 33 mW using P = 3.3 V x 0.010 A. Actual dissipation varies with GPIO activity, peripheral use, clock frequency, and the package thermal path. Verify the maximum junction temperature and exposed-pad layout in the manufacturer datasheet before treating this estimate as a thermal design limit.
