MC9S08RE8CFGE 概述
An 8-bit microcontroller is a compact embedded processor designed to execute control logic, monitor digital inputs, operate peripherals, and manage system behavior in appliances, industrial equipment, access systems, and small consumer products. The S08 family provides a practical platform for applications that need deterministic embedded control without the memory and processing demands of a higher-bit microcontroller. MC9S08RE8CFGE is therefore positioned as a low-complexity, Flash-based MCU rather than a signal-processing or high-performance computing device.
The verified data identifies the principal engineering features as an 8-bit architecture, 8 MHz operating speed, and 8 KB Flash memory. The Flash organization of 8K x 8 supports firmware storage in a compact package while keeping the external memory requirement low. The 44-LQFP package provides a defined, inspectable leaded footprint suitable for conventional PCB assembly and prototyping. The 10 x 10 mm package dimensions help support compact control boards, although the leaded format occupies more board area than a comparable fine-pitch package.
The MC9S08RE8CFGE can be used as the central controller in keypad interfaces, relay-control boards, motor-control peripherals, sensor-conditioning systems, and compact consumer products. Its 8-bit processing and 8 MHz clock are appropriate for supervisory control, digital state machines, timing functions, and peripheral coordination. Designers should verify pin-level functions, voltage limits, memory organization, peripheral availability, clock requirements, and programming details in the official datasheet before finalizing a new PCB or production firmware.
The 44-LQFP footprint simplifies assembly compared with a very fine-pitch package and provides good access to pins for continuity testing. Because the verified data does not include the complete pinout, electrical operating limits, peripheral list, supply-voltage range, or package drawings, those values must be confirmed from the manufacturer datasheet. MC9S08RE8CFGE should be selected when an S08 8-bit, 8 MHz, 8 KB Flash controller in a 44-LQFP package is specifically required.
This page consolidates verified distributor specifications, package information, sourcing links, datasheet references, and engineering guidance. It also separates confirmed facts from parameters that require datasheet verification, helping engineers evaluate MC9S08RE8CFGE for embedded-control designs without confusing an S08 MCU with unrelated 8-bit or cross-package devices.

典型应用
MC9S08RE8CFGE 适用于 6 应用s: Compact Embedded Control Board, Keypad and Access-Control Interface, Industrial Relay and Sequencer Control, Small Motor-Control Peripheral, Sensor and Digital I/O Conditioning, Consumer Appliance Controller.
Compact Embedded Control Board
MC9S08RE8CFGE fits compact supervisory controllers that monitor digital inputs, coordinate peripheral states, and execute firmware from its 8 KB Flash memory. Its 8 MHz S08 core is appropriate for deterministic control loops, state machines, keypad handling, and timing functions. The 44-LQFP 10 x 10 mm package is easy to assemble and inspect, although the complete pinout and electrical limits must be confirmed in the NXP datasheet before schematic capture.
推荐
Keypad and Access-Control Interface
The 8-bit MC9S08RE8CFGE can serve as the central controller in keypad, credential, or access-control interfaces where firmware scans inputs, manages indicators, and enforces timing sequences. An 8 MHz clock supports responsive polling and event-driven logic, while 8 KB Flash provides space for compact control firmware. Verify pin multiplexing, voltage levels, debounce requirements, and any security-related peripheral requirements in the official datasheet.
推荐
Industrial Relay and Sequencer Control
MC9S08RE8CFGE is suitable for relay sequencing, machine interlocks, and small industrial automation modules where an 8-bit MCU handles discrete control rather than complex computation. Its 8 MHz operation can manage debounce, timing, state transitions, and actuator sequencing, while the Flash memory holds compact application code. Confirm output-driver ratings, isolation boundaries, flyback protection, and electrical limits before connecting power-stage devices.
推荐
Small Motor-Control Peripheral
An MC9S08RE8CFGE-based module can handle low-complexity motor functions such as command decoding, limit monitoring, timing, and enable sequencing. The 8-bit S08 architecture is appropriate when the controller coordinates external power electronics rather than executing advanced motor algorithms. The designer must confirm PWM, timer, pin, and electrical requirements in the manufacturer datasheet and provide suitable protection between the MCU and the motor driver.
推荐
Sensor and Digital I/O Conditioning
MC9S08RE8CFGE can act as a digital front-end for sensor modules, threshold monitoring, and I/O aggregation. Its 8-bit processing is useful for converting discrete inputs into system events and coordinating alarms or actuators, while 8 KB Flash accommodates compact control routines. ADC resolution, comparator availability, I/O count, and input thresholds are not specified in the verified data and must be checked before selecting it for analog or high-speed sensing.
推荐
Consumer Appliance Controller
MC9S08RE8CFGE can support compact appliance controllers that coordinate buttons, displays, relays, sensors, and operating modes. The 8 MHz S08 core and 8 KB Flash are appropriate for embedded supervisory functions where low cost and simple firmware are priorities. Because the verified source does not specify RAM, display interfaces, timers, or electrical limits, the complete appliance requirements should be compared with the official datasheet and reference designs.

设计说明
Use the official MC9S08RE8CFGE package drawing to create the 44-LQFP land pattern and confirm pin 1 orientation before routing. The verified data confirms a 44-LQFP 10 x 10 mm package but does not provide pad dimensions or pin functions. Keep programming, reset, clock, ground, and decoupling connections accessible for manufacturing and validation.
Confirm the device's supply-voltage limits, operating current, reset behavior, and recommended decoupling from the NXP datasheet before connecting external circuitry. The verified listing provides 8 MHz and 8 KB Flash information but no electrical current or voltage limits. Size nearby passive components only after those values and the reference circuit requirements are known.
Do not assume that another S08-family MCU is a drop-in replacement. MC9S08AC8CFGE, MC9S08AC16CFGE, MC9S08FL8CLC, and MC9S08AC60CPUE may be related devices, but the supplied search data does not prove identical pinout, memory map, clocking, peripherals, or electrical limits. Compare the official datasheets and package drawings and retest firmware before substitution.
