MC9S08RD16FG - 8-Bit 8MHz 16KB MCU | Motorola | 44-LQFP
N.º da peça: MC9S08RD16FG ✓ AtivoMC9S08RD16FG Visão geral
A microcontroller is a programmable semiconductor that integrates a processor core, memory, and peripheral functions onto one device. The S08 architecture belongs to the broader 8-bit microcontroller family and is commonly used for compact control tasks involving digital inputs, outputs, timers, communications, and analog signal conditioning. Compared with a discrete processor design, an integrated MCU reduces component count, simplifies firmware deployment, and keeps the control system physically compact.
The MC9S08RD16FG combines 16 KB of flash memory with an 8 MHz operating clock in a 44-pin LQFP package. Its flash-based program memory permits firmware to be retained when power is removed and updated through the device programming workflow. The 44-LQFP format provides substantially more external connections than smaller 8-bit packages, allowing more peripheral signals to reach the processor without requiring a larger board footprint.
The S08 CPU is designed for embedded control rather than high-performance computing. Its 8-bit architecture is appropriate for sequential logic, timers, communication protocols, and system-state monitoring, while the 8 MHz clock establishes the device’s operating-rate class. Exact memory architecture, peripheral assignments, electrical limits, and timing figures should be confirmed against the manufacturer datasheet before schematic capture, firmware configuration, or PCB layout.
Typical uses for this controller class include industrial panel controls, building and access equipment, appliance control boards, instrumentation, and compact motor-control interfaces. A 44-LQFP device is particularly useful when a design needs more I/O than a small-package MCU while retaining a straightforward embedded programming model. The 10 mm by 10 mm package also remains practical for multilayer boards where adequate escape routing is available.
Design planning should begin with the manufacturer pin-description table and the electrical characteristics section. Confirm which peripheral functions are available on each package pin, whether unused pins require specific termination, what clock and reset connections are required, and which programming or debug interfaces are used. Component values, decoupling requirements, and allowed tolerances should follow the datasheet recommendations rather than generic MCU conventions.
This product page consolidates the verified device identity, package information, sourcing path, technical alternatives, and application guidance into an engineering-focused reference. The comparison also distinguishes documented electrical facts from parameters that still require direct confirmation, helping designers evaluate the MC9S08RD16FG before committing it to an embedded-control design.

Aplicações típicas
MC9S08RD16FG é adequado para 6 aplicaçãos: Industrial Equipment Control, Appliance Control Board, Building Access and Security Panel, Instrumentation and Data Acquisition, Battery-Powered Sensor Node, Compact Motor and Relay Interface.
Industrial Equipment Control
The MC9S08RD16FG fits compact industrial equipment controllers that combine digital interlocks, status indication, timers, and communications in one board. Its 8 MHz HC08/S08 processor supports responsive embedded sequencing, while 16 KB of flash provides room for application firmware and fixed control logic. The 44-LQFP package offers a practical number of external connections for buttons, sensors, relays, and bus transceivers. Before finalizing the design, confirm the exact peripheral multiplexing, electrical limits, and environmental grade in the manufacturer datasheet.
Appliance Control Board
The MC9S08RD16FG is appropriate for appliance control boards that coordinate user inputs, display segments, temperature-related sensing, and actuator outputs. Its 8-bit architecture and 8 MHz operating rate align with simple sequencing and state-machine firmware rather than graphics-intensive workloads. Sixteen kilobytes of flash supports a dedicated control program, and the 44-LQFP package simplifies access to multiple discrete signals. Validate the pin assignments, ADC needs, reset behavior, and communication requirements before committing the controller to production.
Building Access and Security Panel
A security or access-control panel can use the MC9S08RD16FG to supervise keypad inputs, indicator states, lock or alarm outputs, and an optional external communications link. The 8 MHz S08 CPU supports event-driven firmware for debouncing and state management, while 16 KB of flash permits retention of application code and configuration logic. The 44-LQFP package provides additional signal routing flexibility compared with a small-outline MCU. Review electrical robustness, watchdog operation, and security requirements before deployment.
Instrumentation and Data Acquisition
The MC9S08RD16FG can serve as the supervisory controller in compact instrumentation systems that collect digital measurements and coordinate displays, alarms, and data-transfer interfaces. Its 8-bit processing capability is suitable for sensor conditioning support, threshold logic, calibration tables, and low-bandwidth control functions. With 16 KB of flash and a 44-LQFP package, the device offers a balance of embedded program space and I/O access. Confirm ADC characteristics, timer precision, reference quality, and interface timing in the datasheet.
Battery-Powered Sensor Node
The MC9S08RD16FG can be evaluated for a battery-powered sensor node where an 8-bit MCU must read switches or external sensing circuits, manage a low-power duty cycle, and report status through a serial link. Its 8 MHz operating class and 16 KB flash support compact control firmware, while the 44-LQFP package offers broad peripheral access. Battery life depends on sleep currents, wake-up sources, and the external sensor load, so verify those electrical characteristics and design the regulator for the actual duty cycle.
Compact Motor and Relay Interface
The MC9S08RD16FG is a candidate for compact motor, solenoid, or relay-interface controllers that require deterministic sequencing, protection coordination, and several discrete I/O points. Its 8 MHz S08 processor can execute a state machine for motion profiles, interlocks, or timed actuation, and 16 KB of flash is useful for retaining control tables and diagnostic logic. The 44-LQFP package makes numerous signal connections available. Separate drivers and protection components remain necessary, and all timing and current limits must come from the device documentation.

Notas de projeto
Verify the recommended supply range, absolute-maximum limits, internal supply pins, and required bypass capacitors in the manufacturer datasheet before finalizing the power architecture. Place each required bypass capacitor close to its associated device pin, use the specified voltage and tolerance, and keep switching-regulator and high-current return paths away from sensitive input traces. The 8 MHz operating rate does not by itself define a safe input voltage, so do not infer the supply range from clock speed.
Design the 44-LQFP footprint from the manufacturer’s package drawing rather than from a generic 44-pin library symbol. Confirm body size, lead span, pitch, pin-1 orientation, and exposed-pad requirements where applicable. Keep programming, reset, clock, and debug nets accessible for test, provide clear assembly orientation marking, and verify that courtyard and land-pattern dimensions accommodate the selected PCB manufacturing process.
Do not substitute the base MC9S08RD16 designation without checking the complete ordering suffix, temperature grade, and package drawing. Multiplexed peripheral functions may move between pins in related family members, and a footprint match alone does not guarantee software compatibility. Review the device pin-description table, reset requirements, clock options, programming method, and errata before releasing schematic, PCB, and firmware revisions.
