MC9S08RC8FGE - 8-Bit 8MHz MCU 8KB Flash 44-LQFP | NXP
MPN: MC9S08RC8FGE ✗ پایان تولیدMC9S08RC8FGE نمای کلی
The S08 family is a general-purpose 8-bit microcontroller architecture used for control-oriented products. A microcontroller combines a CPU core, program memory, data memory, I/O ports, timers, and communication peripherals on one integrated circuit. This makes the MC9S08RC8FGE suitable for products that need deterministic embedded control without a separate external memory device.
Key specifications include 8 KB (8K x 8) of Flash program memory, 1K x 8 RAM, 39 I/O pins, an 8 MHz maximum speed, and an internal oscillator. The device also includes SCI connectivity, PWM, a watchdog timer, low-voltage detection, and power-on reset functions according to the supplied component listings.
The 44-LQFP package provides 39 external I/O connections and is suitable for compact, leaded industrial and consumer assemblies. Because the MCU includes an internal oscillator and Flash memory, a basic design can minimize external component count while retaining dedicated serial communication and timing functions.
Typical uses include universal remote controls, handheld instruments, and portable consumer devices. Its low-power technology and multiple power-management modes also make it relevant to battery-operated equipment where average current consumption and standby behavior affect product usability.
The primary design consideration is that MC9S08RC8FGE is reported as obsolete. New production should therefore be planned around confirmed lifecycle and availability rather than assuming a long-term supply window. Any replacement must be checked carefully for memory size, S08 peripheral compatibility, package footprint, pin mapping, voltage range, clock requirements, and software migration effort.
This product data combines verified distributor and manufacturer-page attributes with practical sourcing and design context. It highlights the exact memory, I/O, speed, package, and lifecycle information needed to assess whether an existing MC9S08RC8FGE design can remain unchanged or requires redesign.

کاربردهای معمول
MC9S08RC8FGE مناسب است برای 6 کاربردs: Universal Remote Controls, Handheld Instruments, Portable Consumer Devices, Battery-Powered Sensor Interfaces, Small Industrial Control Modules, Serial Communication Adapters.
Universal Remote Controls
The MC9S08RC8FGE fits a universal remote because its 8-bit HCS08 core can handle button decoding, command tables, and low-rate control logic within 8 KB of Flash. The 39 I/O pins provide ample connections for keypad scanning, status indicators, and external interfaces, while SCI supports communication with a host or accessory. Using the internal oscillator can simplify the RF-control board and reduce component count. The principal limitation is the obsolete lifecycle and modest 1 KB RAM, so production redesigns should consider a currently supported MCU. Existing remote-control firmware should also be checked for peripheral timing and interrupt assumptions before the part is sourced.

Handheld Instruments
The MC9S08RC8FGE can serve as the control processor in a handheld instrument when the instrument requires 39 I/O connections, serial communication, and compact embedded logic. SCI connectivity is useful for connecting a sensor board, display module, or calibration equipment, while PWM and watchdog functions support periodic measurement and system recovery. The 10 x 10 mm 44-LQFP package helps preserve board area in portable products. Because the MCU is obsolete and supplies only 1 KB of RAM, engineers must verify interrupt depth, buffer requirements, and firmware size. A supported 8-bit or 32-bit MCU may provide a safer path for a new instrument platform.
پیشنهادی
Portable Consumer Devices
The MC9S08RC8FGE's 8 KB Flash, internal oscillator, low-power technology, and multiple power-management modes suit compact portable products where board area and standby consumption are important. Its 39 I/O pins can support user inputs, indicators, sensors, and a serial link without requiring a separate bus transceiver for basic control tasks. Using the listed 2.5 V or 3.3 V operation can simplify power architecture when the rest of the portable product uses the same rail. For a new consumer launch, lifecycle risk dominates the otherwise attractive integration level. The product team should balance board-reuse savings against tooling, certification, and long-term component-availability requirements.

Battery-Powered Sensor Interfaces
The MC9S08RC8FGE can act as a low-duty-cycle sensor interface when the design uses its internal oscillator, SCI peripheral, and multiple low-power modes. The controller can wake for measurement, convert results, transmit data, and return to a low-power state without requiring a large external support network. Its 39 I/O pins allow several sensors, status lines, and switches to share a compact controller. Designers must verify the exact standby and run-current values in the full datasheet because they were not included in the supplied verified data. The obsolete status also makes this role better suited to maintaining an existing product than launching a new connected sensor platform.
پیشنهادی
Small Industrial Control Modules
The MC9S08RC8FGE's 39 I/O pins and SCI connectivity make it applicable to compact industrial modules that supervise switches, indicators, and a serial master. The internal oscillator reduces the need for a dedicated crystal circuit, while PWM and watchdog-timer functions support timing and recovery tasks. The 44-LQFP package remains practical for leaded surface-mount assembly and provides more I/O than a typical small-package MCU. Before reuse, engineers should verify industrial temperature-grade requirements, isolation, EMC exposure, and supply lifecycle because those details were not supplied in the verified records. A supported MCU should be preferred when equipment qualification or long-term supply is required.
پیشنهادی
Serial Communication Adapters
The MC9S08RC8FGE's SCI interface, internal oscillator, and 39 available I/O positions support small serial adapters that translate device commands or collect button and sensor states. A protocol-conversion or diagnostic product can place the MCU beside a transceiver, configure SCI baud rate, and use additional pins for status indicators or configuration controls. Flash memory allows firmware to be updated or reconfigured without external storage. However, the 1 KB RAM and 8 KB Flash limit suitable for complex protocol stacks, so this application is best for lightweight command handling. Since the component is obsolete, preserve existing firmware and test vectors when sourcing a replacement rather than changing the protocol architecture.

- Flash-based standalone embedded control (در مقابلMC9S08AC32MFGE)
یادداشت‌های طراحی
Do not treat a related S08 device as a drop-in replacement merely because it has a similar orderable number. MC9S08FL8CLC and MC9S08AC32MFGE appear in the supplied comparison results, but no verified evidence establishes a shared 44-LQFP footprint, identical pin mapping, matching memory limits, or equivalent SCI and timer resources. Verify the complete pin list, alternate-function routing, reset behavior, clock assumptions, and peripheral register compatibility before changing a production BOM.
The verified data identifies 2.5 V and 3.3 V operation but does not provide minimum, maximum, or per-rail operating-voltage limits. Confirm the complete supply range and current consumption from the manufacturer datasheet before connecting sensors, transceivers, and pull-up networks to the I/O pins. Also verify that every external signal remains within the selected rail; the internal oscillator simplifies clocking but does not remove the need for careful power-domain compatibility checks.
Use the 44-LQFP 10 x 10 mm footprint only after checking the official package drawing and land pattern against the PCB library. Place decoupling close to the supply pins, route exposed or sensitive signals away from power-current transitions, and confirm all 39 I/O positions against the design's schematic. The supplied search records do not contain a complete pinout, so do not reconstruct the footprint from an unverified third-party pin table.
The 8 KB Flash and 1 KB RAM constraints can create hidden redesign problems even when a replacement appears electrically similar. Check linker-map utilization, stack depth, serial receive buffers, interrupt service routines, and bootloader space rather than comparing nominal Flash capacity alone. Preserve the original executable image and test hardware whenever possible so that timing, watchdog behavior, SCI framing, and power-management transitions can be compared during qualification.
