MC9S08RC8FJE - 8-Bit 8MHz MCU, 8KB Flash | NXP
MPN: MC9S08RC8FJE ✓ AktifMC9S08RC8FJE Ringkasan
A microcontroller is a programmable semiconductor that integrates a CPU core, nonvolatile program memory, volatile data memory, and peripherals such as timers, serial interfaces, and I/O ports. The HCS08 CPU core belongs to the broader microcontroller hierarchy: HCS08 core, 8-bit microcontroller, embedded processor, and semiconductor. The MC9S08RC8FJE is intended to provide an integrated platform for control logic, user-interface scanning, sensing, and communication in small embedded products.
The verified device data identifies 8 KB (8K x 8) of Flash program memory, 1K x 8 RAM, 25 I/O, an 8 MHz operating speed, and an internal oscillator. Flash memory supports in-system or in-application programming when used with the appropriate device programming flow, while RAM supports working variables, stack operations, and peripheral data handling. The internal oscillator can reduce the number of external timing components required in a compact design.
Typical application signals for this controller family include universal remote controls, handheld instruments, and portable consumer devices. These applications benefit from a compact package, integrated program and data memory, and an 8-bit control-oriented architecture. The verified listing identifies a 32-LQFP, 7x7 mm package with a commercial temperature grade, while detailed electrical limits and peripheral assignments should be confirmed in the official manufacturer datasheet before design release.
When designing a PCB, place decoupling capacitors close to the device power pins and route high-current and sensitive signals away from the controller clock and programming interface. Confirm the exact pin names, alternate functions, voltage limits, oscillator options, and programming connections against the official MC9S08RC8 datasheet. This data page uses only values present in the supplied verification records; unspecified electrical details are intentionally marked as data needed rather than estimated.

Aplikasi Biasa
MC9S08RC8FJE patut untuk 6 aplikasis: Universal Remote Control, Handheld Instrument, Portable Consumer Device, Simple Control Panel, Battery-Powered Sensor Node, Embedded Interface Controller.
Universal Remote Control
The MC9S08RC8FJE fits compact remote-control products because its 8-bit HCS08 core can manage button scanning, command encoding, status logic, and user feedback without a separate processor. Its verified 8 KB Flash program memory provides room for firmware storage, while 1K x 8 RAM supports state variables and short data buffers. The 25 I/O count leaves multiple connections for keys, indicators, or external control lines. Use the internal oscillator documented in the supplied records to reduce unnecessary clock circuitry, but verify exact current consumption and power-management modes in the official datasheet before designing a coin-cell or battery-powered product.

Handheld Instrument
For a handheld measurement or test instrument, the MC9S08RC8FJE provides an 8 MHz 8-bit control core, 8 KB Flash firmware storage, 1K x 8 RAM, and 25 I/O in a 7x7 mm LQFP. These resources suit display-control logic, keypads, measurement sequencing, and communication between a front panel and other embedded blocks. The compact surface-mount package helps preserve board area, while the internal oscillator can simplify the clocking plan. Before selecting it for a precision instrument, confirm the actual analog interface requirements, ADC availability, reference accuracy, timing specifications, and supply-voltage range in the manufacturer documentation.
Disebarkan
Portable Consumer Device
The MC9S08RC8FJE is suitable for portable consumer products where a small controller manages local controls, indicators, and simple peripheral state. The verified 8 MHz operating speed is appropriate for event-driven user-interface tasks, while 8 KB Flash and 1K x 8 RAM provide a modest but workable embedded footprint. Its 32-LQFP package supports denser PCB layouts than a large through-hole controller, and the documented internal oscillator may reduce component count. Battery optimization requires additional verification of sleep modes, operating current, wake-up behavior, and peripheral clock gates because those values are not included in the supplied records.

Simple Control Panel
The MC9S08RC8FJE can serve as the central controller for a small keypad-based control panel, using its 25 I/O for switch inputs, status outputs, and communication signals. The 8-bit HCS08 architecture is aligned with straightforward supervisory tasks such as debouncing, mode selection, indicator sequencing, and command routing. With 8 KB Flash available for firmware and 1K x 8 RAM for working state, it can host moderate control logic in a compact 7x7 mm LQFP footprint. Validate pin multiplexing, interrupt assignments, reset behavior, and programming-test access against the official pinout before laying out the PCB.
Disebarkan
Battery-Powered Sensor Node
The MC9S08RC8FJE may be used in a small sensor-node controller when its required sensing and communication functions match the device peripherals. The 8 MHz HCS08 core can coordinate sensor acquisition, threshold decisions, data buffering, and low-rate control communications, while 25 I/O supports external sensors and status signaling. The internal oscillator can help simplify the hardware, but low-power suitability must be proven against the exact datasheet current specifications. In particular, verify active current, standby or sleep behavior, wake-up time, I/O leakage, and whether the sensor interface requires functions not confirmed in the supplied data.
Disebarkan
Embedded Interface Controller
The MC9S08RC8FJE is a reasonable candidate for an embedded interface controller that bridges buttons, indicators, and a larger system bus, provided its pin multiplexing and timing satisfy the design. The verified 25 I/O and 8 MHz clock provide a practical platform for protocol handling, state machines, and supervisory functions, while 8 KB Flash is suitable for compact firmware. Because the supplied records do not specify UART, SPI, I2C, CAN, USB, or other peripheral details, engineers must inspect the official datasheet before assigning communications pins. A footprint match alone does not guarantee software or electrical drop-in compatibility with another MCU.

Penyeberangsung Jelas
- Compact 8-bit S08 control platform (vsMC9S08QE32CLCR)

- Application-oriented 25 I/O and internal oscillator (vsMC9S08QE32CLCR)
Catatan Desain
Use a manufacturer-approved 32-LQFP land pattern and verify the exact pin numbering before routing. Place the device's supply bypass capacitors as close as practical to their corresponding power pins, with short, low-loop-area connections. Because the supplied records identify a 7x7 mm LQFP but do not provide a complete pinout, do not infer exposed-pad, programming, reset, or ground connections from the package outline alone. Validate the PCB library against the official datasheet and assembly notes.
The verified data confirms an 8 KB Flash, 1K x 8 RAM, 8 MHz, 25-I/O device but does not provide supply voltage or current limits. Before connecting external circuits, identify every supply and ground pin in the official datasheet, check the operating voltage range, and calculate the worst-case load from peripherals rather than from the CPU core alone. Add local decoupling and provide a clean return path for switching or sensor loads to reduce noise on the controller rail.
Do not treat a matching package name as proof of drop-in replacement. The supplied cross-reference results mention MC9S08QE32CLCR and MC9S08RE16CFDE, but they do not prove identical pin mappings, memory sizes, voltage limits, peripheral functions, or firmware behavior. For a redesign, create a pin-by-pin difference table, compare reset and programming pins, and review timing, interrupts, clocking, and memory-map assumptions before substituting any part.
Route high-current outputs and externally driven signals away from sensitive control inputs and programming nets. Keep oscillator and reset-related traces short, preserve the device's recommended decoupling arrangement, and check that exposed or adjacent ground connectivity follows the official package drawing. If the controller drives relays, displays, or motor-related circuitry, use appropriate isolation and protection rather than relying on the 25 I/O pins as unlimited power outputs.
Maklumat Kesediaan
The supplied verified product records do not state RoHS, REACH, lead-free, halogen-free, conflict-minerals, or automotive qualification status. Commercial temperature grade is listed in a distributor result, but that does not by itself establish AEC-Q100 qualification.
