MC9S08RC16FG - 8-Bit 8MHz 16KB Flash MCU | NXP
Référence : MC9S08RC16FG ✗ Fin de vieMC9S08RC16FG Présentation
A microcontroller is a programmable integrated circuit that combines a processor core, memory, and peripherals into one component for controlling electronic systems. The S08 family belongs to the broader embedded-microcontroller hierarchy, where firmware executes from internal flash and interacts with sensors, switches, communications interfaces, and other external circuits. This role distinguishes the MC9S08RC16FG from passive components and from general-purpose processors intended for larger computing systems.
The principal documented characteristics of the MC9S08RC16FG are its 8-bit architecture, 8 MHz operating frequency, and 16 KB flash capacity. The flash arrangement is identified as 16K x 8, meaning the program memory stores 16,384 eight-bit locations. These figures position the device for embedded products requiring moderate code space without the complexity of a larger controller. The 44-LQFP package also supports compact, high-density PCB layouts while exposing more I/O than a small-outline package.
The S08 architecture is designed for cost-conscious embedded control, where deterministic control behavior, general-purpose I/O, and integrated nonvolatile program memory are more important than a large high-level operating-system footprint. The 8 MHz clock provides the execution basis for the controller, while the 16 KB flash region supports firmware storage and boot-oriented embedded routines. Detailed RAM organization, peripheral channels, voltage limits, and electrical timing must be confirmed in the manufacturer datasheet before a board design is released.
Typical application directions include appliance controllers, small motor-control boards, digital keypads, industrial modules, sensor-interface products, and compact access-control equipment. In each case, the device can coordinate inputs and outputs through firmware while its flash memory retains the application program. The 44-LQFP footprint is especially useful when a design needs more external connections than a small 20-pin package can offer.
Designers should verify the complete pin assignment, power requirements, clock options, programming method, and peripheral multiplexing before layout. The package drawing and pin descriptions in the manufacturer datasheet are the authoritative references for track routing and programming-header connections. A footprint based only on the 44-LQFP body size is incomplete unless pad dimensions, pin numbering, and exposed thermal-pad treatment are also confirmed.
This product page consolidates the verified device identity, package information, source documents, sourcing guidance, and engineering-focused selection considerations. It also separates confirmed characteristics from parameters that require direct datasheet verification, helping engineers plan a design without overlooking memory, package, or cross-reference constraints.

Applications typiques
MC9S08RC16FG convient pour 6 applications: Appliance Control Board, Industrial Sensor Interface, Access Control and Keypad Reader, Compact Motor and Relay Controller, Battery-Powered Monitoring Module, Data Acquisition Front End.
Appliance Control Board
The MC9S08RC16FG fits compact appliance controllers where an 8-bit processor, 8 MHz clock, and 16 KB of nonvolatile flash can run the operating firmware. Its 44-LQFP package provides a useful balance between board area and external connection capacity. The controller can coordinate button inputs, indicator outputs, timing functions, and sensor signals while retaining its program through power removal. Final design work should verify the exact I/O mapping, timer resources, voltage limits, and flash endurance required by the appliance.
Recommandé
Industrial Sensor Interface
An MC9S08RC16FG-based module can translate sensor and switch inputs into a compact embedded-control platform. The 8 MHz S08 processor supplies deterministic control-loop execution, while 16 KB of flash provides nonvolatile storage for configuration tables and application firmware. The 44-LQFP footprint allows the design to route multiple discrete signals rather than forcing them through a smaller package. Engineers should confirm the required timer channels, serial interface, analog functions, and operating-temperature limits in the datasheet.
Recommandé
Access Control and Keypad Reader
The MC9S08RC16FG is suitable for a keypad reader or access-control peripheral that scans user inputs, controls indicators, interprets a credential, and communicates with a door controller. Its 8-bit architecture and 8 MHz clock fit event-driven firmware, and 16 KB of flash is appropriate for compact application code and retained settings. The 44-LQFP package offers more I/O opportunities than a small controller package. Communication protocol timing, security requirements, and power behavior must be confirmed before implementation.
Recommandé
Compact Motor and Relay Controller
A small relay or low-power motor-control board can use the MC9S08RC16FG for sequencing, timeout handling, input monitoring, and status reporting. The 8 MHz processor provides adequate control bandwidth for many non-timing-critical actuator routines, while the 16 KB flash stores the firmware. Its 44-LQFP package offers enough pins for control signals, feedback inputs, and communications. The designer must verify PWM or timer availability, output drive limits, inductive-load protection, thermal margins, and the controller's operating voltage range.
Recommandé
Battery-Powered Monitoring Module
The MC9S08RC16FG can support a compact battery-powered monitoring module that periodically reads inputs, processes local logic, and reports status through a serial link. Its 8-bit S08 architecture and 16 KB flash suit low-complexity firmware, while the 44-LQFP package provides adequate signal access without moving to a very large controller. Because no low-power mode, current consumption, or voltage range is established by the available listing, battery-life calculations must use the manufacturer datasheet and include margin for sensing and communications.
Recommandé
Data Acquisition Front End
The MC9S08RC16FG can act as the local controller for a small data-acquisition front end, sequencing sensor readings and transferring formatted measurements to a host. The 8 MHz processor supports straightforward sampling-control logic, and the 16 KB flash stores firmware and configuration. Its 44-LQFP package allows multiple digital signals to be exposed alongside communications. Critical ADC timing, memory depth, serial bandwidth, and input accuracy must be confirmed because the target's analog and memory specifications are not established in the available product listing.

Principaux différenciateurs
- Established device identity with a confirmed 8-bit and 8 MHz configuration (vs MC9S08QE4CTG)
- Compact 10 mm x 10 mm 44-LQFP implementation (vs MC9S08QE4CTG)
- S08-family firmware continuity (vs MC9S08QE4CTG)
Notes de conception
Use the manufacturer package drawing for the 44-LQFP footprint rather than deriving pad geometry from the 10 mm x 10 mm body size alone. Confirm lead pitch, exposed-pad dimensions, solder-mask clearance, and copper-tolerance requirements before releasing artwork. Place the MCU close to its decoupling and programming-header connections, and route sensitive inputs away from switching nodes to reduce coupling into the control system.
Calculate the local supply requirement from the MCU operating current plus peripheral loads, then add margin for startup and transient conditions. Place the required supply and ground capacitors at the corresponding device pins using the layout guidance in the manufacturer datasheet. Verify minimum input voltage, maximum input voltage, I/O drive limits, and any internal voltage-reference requirements before connecting sensors or external circuits.
Do not assume that two S08-family devices with 44-LQFP packages are interchangeable. Pin multiplexing, timer channels, serial functions, memory maps, interrupts, and programming procedures can differ even when the package is identical. For the MC9S08RC16FG and MC9S08QE4CTG candidate comparison, create a net-by-net migration table and compile both software projects against their respective device headers before approving a substitution.
Reserve a reliable programming path for the target because field firmware updates depend on a stable connection to the programming interface. Follow the datasheet recommendation for signal conditioning or series resistance if required, keep programming-trace geometry away from noisy power stages, and provide a stable ground reference. Review the package pin table and programming configuration section together because unused pins may need specific termination.
