MC9S08RE8FJE Descripción general
A microcontroller is a programmable semiconductor that integrates a processor core, nonvolatile program memory, data memory, peripherals, and input/output circuitry into one device. The MC9S08RE8FJE belongs to the S08 family of 8-bit microcontrollers, a category used for embedded control, monitoring, and simple logic functions. Its 8-bit architecture is suited to compact control tasks rather than high-throughput computing, while its integrated flash supports firmware storage without a separate external memory device.
The verified distributor data identifies the principal attributes as 8-bit processing, 8 MHz operation, and 8 KB of flash memory, with a 32-LQFP package measuring 7 x 7 mm. The LQFP package provides a surface-mount form factor suitable for automated assembly and compact embedded boards. Exact RAM capacity, supply-voltage range, peripheral list, pin assignments, temperature limits, and timing characteristics were not provided in the supplied verified data and therefore are not inferred here.
MC9S08RE8FJE is appropriate for applications such as simple embedded controllers, appliance controls, sensor interfaces, status and sequencing logic, and compact industrial modules where an 8-bit MCU and modest flash capacity are sufficient. The 8 MHz operating frequency provides a defined performance basis for firmware selection, while the 8 KB flash budget constrains program size. Designers should verify the complete device datasheet and pinout before final PCB release.
The 32-LQFP footprint makes layout and assembly more demanding than a small-lead package, but it exposes the device in a standardized, inspectable format for automated production. Decoupling, exposed routing, programming access, and unused-pin handling must be checked against the authoritative NXP documentation. This page combines distributor-confirmed identity, package, memory, and frequency information with procurement guidance and explicitly avoids inventing unverified electrical details.
For sourcing, distributor records list MC9S08RE8FJE from NXP Semiconductors and legacy Freescale Semiconductor listings, with Octopart pages also available for price and availability comparison. Current unit pricing, stock quantity, lifecycle classification, and authorized-distributor status were not included in the provided data, so purchasing decisions require a live distributor quote. Review the official MC9S08RE8FJE datasheet and device-specific documentation before approving a replacement or creating a new PCB footprint.

Aplicaciones típicas
MC9S08RE8FJE es adecuado para 7 aplicacións: Appliance Control, Sensor Interface Module, Status and Sequencing Panel, Compact Industrial Module, Battery-Powered Sensor Node, Communication Gateway Controller, Programmable Logic Controller.
Appliance Control
MC9S08RE8FJE fits compact appliance-control boards where an 8-bit controller must execute deterministic user-interface, relay, timer, and sensor-handling logic. Its confirmed 8 MHz operating frequency defines the processor speed, while 8 KB of flash provides a constrained firmware budget. The 32-LQFP package also supports automated surface-mount assembly. Because RAM, I/O count, and electrical limits were not supplied, confirm them in the official datasheet before assigning motors, heaters, or safety-critical loads.
Recomendado
Sensor Interface Module
The MC9S08RE8FJE can serve as the controller in a small sensor-interface module that samples switches, digital sensors, or simple analog front-end signals and produces local status or control outputs. Its 8-bit S08 architecture is appropriate for basic acquisition and decision logic, and the 8 KB flash limit should be checked against the complete firmware, bootloader, and calibration requirements. The available records do not specify ADC channels, timers, RAM, or pin assignments, so peripheral fit must be verified from the manufacturer documentation.
Recomendado
Status and Sequencing Panel
For a status panel or sequencing controller, MC9S08RE8FJE can coordinate LEDs, input conditions, timing sequences, and communication outputs within an 8-bit embedded-control design. The 8 MHz clock and 8 KB flash are the principal confirmed selection values, making firmware sizing and response-time analysis the first engineering checks. The 32-LQFP package provides a defined 7 x 7 mm surface-mount footprint, but exact I/O availability and pin multiplexing remain unknown from the supplied records and must be checked before schematic capture.
Recomendado
Compact Industrial Module
MC9S08RE8FJE is a plausible controller for a compact industrial module that performs local supervision, periodic measurements, mode selection, and output switching. An 8-bit architecture keeps firmware and hardware requirements manageable for non-high-performance tasks, while the 8 MHz operating point provides a clear baseline for loop timing. Industrial suitability cannot be inferred from the distributor description alone: temperature range, supply voltage, ESD rating, isolation, watchdog behavior, and long-term availability must be confirmed.
Recomendado
Battery-Powered Sensor Node
A battery-powered sensor node may use MC9S08RE8FJE for low-duty-cycle sampling, local filtering, threshold decisions, and periodic reporting when the application fits an 8-bit MCU and 8 KB flash budget. The supplied data does not specify sleep current, active current, voltage range, or timer resources, so battery-life calculations cannot be completed without the datasheet. Confirm low-power modes and wake-up sources before selecting it for an energy-limited product.
Recomendado
Communication Gateway Controller
MC9S08RE8FJE may be used as a protocol or gateway controller when the task is limited to framing, simple state management, status reporting, and control of another communications component. The 8 MHz S08 core and 8 KB flash should be sized against the selected protocol, buffering requirements, and firmware update strategy. The verified records do not identify UART, SPI, I2C, CAN, or other peripherals, so communications capability must be established from the official datasheet rather than inferred from the MCU family name.
Recomendado
Programmable Logic Controller
For a small programmable logic controller, MC9S08RE8FJE can represent the low-level control element that reads discrete inputs and drives outputs according to a compact application program. The 8-bit processing and 8 MB flash-related product positioning should be checked carefully: the verified device data states 8 KB, not 8 MB, of flash. Use the confirmed 8 KB figure for firmware budgeting and verify I/O count, timing, watchdog, and safety requirements before using the device in a replacement PLC design.

Notas de diseño
Use the verified 32-LQFP 7 x 7 mm package designation as the starting footprint, but do not release a PCB footprint until every pad and pin function has been checked against the official MC9S08RE8FJE datasheet. Confirm pin numbering, exposed thermal or ground geometry, package tolerances, assembly land pattern, programming access, and the handling of unused pins. The supplied records do not include a pinout, so generic LQFP assumptions are not sufficient.
Validate the supply voltage range, decoupling requirements, and power-pin arrangement from the manufacturer documentation before schematic release. The verified data confirms an 8-bit, 8 MHz MCU with 8 KB flash but does not state operating voltage or current. Therefore, capacitor voltage rating, regulator headroom, startup behavior, and power-loss sequencing must remain open engineering items rather than assumptions. Record the selected rail and transient conditions in the design review.
Do not size the firmware as though the device has more than the confirmed 8 KB of flash. Budget application code, interrupt handlers, configuration tables, bootloader space, calibration data, and update mechanisms against that figure. RAM is also unknown in the supplied data, so stack depth, buffering, and dynamic allocation must be checked against the authoritative memory map. A candidate replacement should not be approved until both memory and peripheral mappings are reviewed.
Preserve clean routing for power, ground, programming signals, and any clock-sensitive external circuitry. The LQFP lead pitch and 7 x 7 mm body require assembly-capable copper clearance and inspection planning. Because the complete pinout, exposed-pad arrangement, and recommended decoupling are absent from the verified data, use the manufacturer layout guidance rather than extrapolating from another S08 member. Review the final assembly drawing with the contract manufacturer.
