MC9S08RC8CFG - 8MHz 8KB Flash 8-Bit MCU | Motorola | LQFP-44
料号： MC9S08RC8CFG ✗ 停产MC9S08RC8CFG 概述
A microcontroller is a programmable control component that integrates a CPU core, memory, and peripherals on one semiconductor device. The S08 family belongs to the broader embedded-controller hierarchy and is designed for compact control systems rather than high-performance computing. MC9S08RC8CFG combines an 8MHz maximum clock with 8KB Flash, making it appropriate for products that require moderate real-time control, local program storage, and a low component count without an external memory interface.
The verified specifications identify the MCU as an 8-bit S08 device with 8KB Flash and a 44-LQFP package. The S08 architecture uses a CISC-style instruction set and is suited to embedded products requiring straightforward firmware control, GPIO handling, timers, serial communication, and analog or control functions, subject to the exact peripheral configuration in the manufacturer datasheet. The 44-pin package provides substantially more external connection options than small-outline packages, making the device practical for designs needing multiple I/O signals or mixed analog and digital functions.
MC9S08RC8CFG can be considered for industrial controls, consumer appliances, instrumentation, motor and relay control, sensor interfaces, and compact embedded modules. Its 8MHz clock is generally sufficient for supervisory loops, keypad and display handling, communication management, and deterministic low-to-moderate-complexity control. The part is available through multiple distributors, and one verified listing reports an in-stock starting price of $1.4906, while another reports a price of $4.0627; prices should therefore be checked by quantity, condition, and authorized distributor inventory as of 2026-10-30.
For PCB design, verify the exact pin assignments, exposed-pad requirements, decoupling recommendations, and operating-temperature limits in the MC9S08RC8 datasheet before layout release. Because the supplied search results do not include a complete manufacturer pin table, the pinout is intentionally left unavailable rather than presenting guessed pin numbers. Likewise, final peripheral counts, timer resources, ADC specifications, communication interfaces, and electrical timing characteristics require confirmation from the authoritative device documentation.

典型应用
MC9S08RC8CFG 适用于 6 应用s: Industrial Sensor Interface, Consumer Appliance Control, Motor and Relay Control, Battery-Powered Measurement Node, Instrumentation and Test Equipment, Communication Gateway Module.
Industrial Sensor Interface
MC9S08RC8CFG fits compact sensor-hub and condition-monitoring designs that need an 8-bit S08 controller, 8MHz clock, and 8KB Flash for local control code. Its 44-LQFP package provides a larger pin count for digital inputs, outputs, serial signals, and mixed analog connections than a small-outline MCU. The implementation can sample sensors, apply filtering, manage thresholds, and report status without an external processor. The principal engineering check is the exact ADC resolution, channel count, timer resources, and operating-voltage limits, because the supplied excerpts do not provide those details.
推荐
Consumer Appliance Control
The MC9S08RC8CFG is suitable for appliance-control boards that coordinate buttons, indicators, relays, and simple motor functions. Its 8MHz S08 core provides enough clock rate for supervisory logic, while 8KB Flash stores firmware and operating parameters in the MCU itself. The 44-LQFP footprint supports numerous I/O and mixed-function connections on a compact board. Designers should verify output-drive ratings, timing margins, and analog functions in the datasheet, then use transistor or MOSFET stages rather than driving motors or relays directly from general-purpose pins.
推荐
Motor and Relay Control
MC9S08RC8CFG can serve as the supervisory controller in a compact motor, valve, or relay-control module. The 8MHz clock supports deterministic sequencing of discrete control steps, and the 44-pin package leaves room for command inputs, status outputs, and communication links. External MOSFETs or driver circuits should handle load current and voltage transients. Firmware must include safe-state behavior, debounce logic, and timing margins, while the hardware review should confirm whether the selected MC9S08RC8CFG voltage and temperature grade suit the target motor environment.
推荐
Battery-Powered Measurement Node
The MC9S08RC8CFG is applicable to compact, low-duty-cycle measurement nodes where an 8-bit controller processes local sensor data and an 8KB Flash capacity is sufficient for firmware. Its S08 architecture avoids the memory and processing overhead of a larger MCU, while the 44-LQFP package offers more I/O than a minimal package. A battery-powered implementation should confirm sleep-mode current, wake-up behavior, ADC accuracy, and supply-voltage limits because those values are not available in the supplied search data. Firmware should use the low-power modes and duty cycle documented for the exact device suffix.
推荐
Instrumentation and Test Equipment
MC9S08RC8CFG can be used in compact instrumentation where local control, digital I/O, and serial communication are more important than high-end processing. The 8MHz S08 core can execute measurement sequencing, calibration logic, and front-panel control, while the 44-pin LQFP package supports mixed external connections. Noise-sensitive analog routing still requires careful partitioning from digital and switching circuitry. Before release, verify the ADC, timer, oscillator, and communication specifications in the manufacturer datasheet; those detailed values are not established by the distributor snippets provided here.
推荐
Communication Gateway Module
MC9S08RC8CFG can act as a local protocol-conversion or gateway controller in compact embedded equipment. Its 8MHz S08 processor can handle address and message parsing, while 8KB Flash holds configuration and protocol routines. The 44-pin package provides additional I/O for status indicators, configuration inputs, and communications. A practical design should isolate interface transceivers from the MCU supply, provide proper connector protection, and verify the exact UART or other serial resources. The verified listings do not specify peripheral counts, so those functions must be confirmed before assigning hardware connections.

关键差异点
- Documented 8MHz operating speed and 8KB Flash configuration （对比 MC9S08RC8CAG)

- Widely visible distributor availability （对比 MC9S08RC8CXG)
设计说明
Use the exact 44-LQFP footprint and pin table from the manufacturer datasheet rather than a generic 44-pin library symbol. Confirm pad dimensions, exposed-thermal-pad treatment, pin-1 orientation, and assembly tolerances before Gerber release. Place input and output decoupling close to the corresponding power pins, and reserve the required programming, reset, clock, and debug connections according to the device reference design.
The verified records associate MC9S08RC8CFG with 2.5V to 3.6V operation, while one listing states 1.8V to 3.6V. Resolve that discrepancy using the exact ordering suffix and manufacturer datasheet before selecting a supply. Provide local bypass capacitance and clean power routing, and account for startup, reset, and peripheral current in the system power budget.
Keep oscillator and reset traces short, away from relay-coil, motor, and switching-node return currents. Route communications and analog inputs away from digital clock edges and power converters, with a continuous ground reference where possible. For designs using external transceivers, place protection and interface circuits near the connector and keep high-current returns out of the MCU analog and digital ground paths.
