MC9S08RD8CFJ - 8-Bit 8MHz S08 MCU | 32-LQFP
MPN: MC9S08RD8CFJ ✗ پایان تولیدMC9S08RD8CFJ نمای کلی
An S08 microcontroller is an embedded processing component designed to execute firmware, read inputs, control outputs, and manage communication tasks in a compact embedded system. The term microcontroller describes a processor core, memory, and peripherals integrated on one semiconductor device. In the product hierarchy, the MC9S08RD8CFJ belongs to the S08 family of 8-bit microcontrollers, where the 8-bit architecture supports economical control-oriented systems with relatively low software and hardware complexity.
The principal features supported by the verified data are an 8 MHz maximum operating frequency, 8 KB of built-in Flash program memory, 1 KB of RAM, an 8-bit processor architecture, and a 32-LQFP package measuring 7 x 7 mm. Built-in Flash permits firmware to be stored directly on the microcontroller, while the 1 KB RAM provides volatile working memory for stack, variables, and runtime operations. The 1.8 V to 3.6 V operating range supports low-voltage embedded equipment.
The MC9S08RD8CFJ is specifically identified as part of the S08 product family and is positioned for applications requiring compact, deterministic embedded control. Its 8-bit architecture and 8 MHz operating rate are suitable for supervisory control loops, programmable logic functions, panel interfaces, and basic peripheral control. The verified distributor excerpt does not enumerate the complete peripheral set, clock configuration, timer implementation, or communication blocks, so those details should be checked against the manufacturer documentation before final design approval.
Typical use cases include industrial control modules, building equipment, appliance controllers, instrumentation interfaces, and low-cost embedded products with modest processing requirements. A design team may select this microcontroller when the required firmware fits within 8 KB of Flash, working memory remains within 1 KB, and a compact 32-LQFP surface-mount footprint is preferred over a larger through-hole package.
The principal design consideration is verification of the complete electrical and pin configuration before schematic capture. The available sources confirm the core voltage, temperature, memory, clock, and package data, but they do not provide a complete pin table, absolute-maximum ratings, timing characteristics, or detailed peripheral specifications. Those values must be obtained from the authoritative MC9S08RD8CFJ documentation before PCB release or production use.
This product record consolidates the verified distributor specifications for the MC9S08RD8CFJ and separates confirmed characteristics from unavailable technical data. It also documents current sourcing links, package characteristics, procurement limitations, and design-validation requirements so engineers can assess fit before committing the part to an embedded-control platform.

کاربردهای معمول
MC9S08RD8CFJ مناسب است برای 6 کاربردs: Industrial Control Module, Appliance Controller, Building Equipment Interface, Instrumentation Front Panel, Battery-Powered Sensor Node, Programmable Logic Controller.
Industrial Control Module
The MC9S08RD8CFJ can serve as the central controller in a compact industrial control module when the required firmware fits within 8 KB of Flash and active working data remains within 1 KB of RAM. Its verified 8 MHz S08 processor provides a straightforward platform for sequencing, status monitoring, and discrete output control. The 1.8 V to 3.6 V operating range fits low-voltage embedded equipment, while the -40°C to +85°C specification covers industrial-temperature environments. Before final schematic approval, engineers must confirm the available GPIO, timers, communication peripherals, watchdog behavior, and programming pins from the official documentation because those details were not exposed in the verified snippets.
پیشنهادی
Appliance Controller
The MC9S08RD8CFJ is appropriate for appliance-control logic that combines deterministic firmware execution with limited memory demand. Its 8 KB built-in Flash can retain a control program without requiring an external memory device, and the 1 KB RAM supports variables and execution context. The 8-bit S08 architecture avoids the cost and power burden of a higher-complexity processor when the task consists mainly of reading switches or sensors and driving relays, indicators, or displays. Its compact 32-LQFP 7 x 7 mm package also helps control board area. Final suitability depends on confirming the required I/O count, timing channels, analog functions, and pin multiplexing against the authoritative package and peripheral documentation.
پیشنهادی
Building Equipment Interface
The MC9S08RD8CFJ can support building-equipment interface functions such as local supervisory control, configuration handling, and communication between sensors and a higher-level controller. The -40°C to +85°C operating range is relevant to equipment installed outside a climate-controlled enclosure, provided board-level self-heating remains controlled. Its 1.8 V to 3.6 V operating voltage supports integration with low-voltage system rails, while 8 KB of Flash and 1 KB of RAM suit compact protocol handlers and configuration logic. Designers must verify serial-interface availability, pin multiplexing, ESD requirements, and communication timing; those parameters are not established by the supplied distributor excerpts.
پیشنهادی
Instrumentation Front Panel
The MC9S08RD8CFJ can be evaluated for an instrumentation front panel that manages indicators, buttons, menu logic, and status reporting. Its 8-bit S08 core and 8 MHz clock are appropriate for straightforward human-interface tasks, and 8 KB of Flash can hold compact embedded firmware. The 32-LQFP package provides a surface-mount option for space-conscious instruments, although its 7 x 7 mm body still requires careful connector placement and copper planning. The 1 KB RAM limitation should be checked against display buffering and communication stacks. Engineers should also confirm the number of usable I/O pins, analog conversion capability, and display or communication interfaces before treating the MCU as a complete panel solution.
پیشنهادی
Battery-Powered Sensor Node
The MC9S08RD8CFJ may suit a low-power sensor node when its 8-bit S08 processing, 8 KB Flash, and 1 KB RAM are sufficient for local measurement and control. Its 1.8 V to 3.6 V operating range allows use with a low-voltage energy-storage rail, but actual battery life depends on sleep-mode current, wake-up behavior, and the selected external sensors. The verified snippets do not identify low-power modes, so power-budget calculations require the official electrical specifications. The 8 MHz operating rate permits responsive foreground processing, while the compact 32-LQFP package assists miniaturization. Designers must also verify battery chemistry, regulator behavior, peak load, and whether Flash programming or periodic logging dominates energy use.
پیشنهادی
Programmable Logic Controller
The MC9S08RD8CFJ is a candidate for small programmable logic controllers that combine fixed control sequences, input scanning, and discrete outputs. The 8 MHz maximum frequency is more than adequate for many conventional control loops, and the 8-bit architecture simplifies both hardware and firmware for deterministic operations. The 8 KB Flash capacity accommodates a compact control program, but the 1 KB RAM requires disciplined buffer and data-management choices. Its industrial -40°C to +85°C range supports controlled cabinets and ordinary industrial environments, while the 32-LQFP package allows a compact controller board. Before selection, verify timer count, capture/compare features, watchdog support, communications, input thresholds, and output-drive limits from the authoritative documentation.

یادداشت‌های طراحی
Design the power rail for the verified 1.8 V to 3.6 V operating range, but do not treat those limits as a complete regulator design specification. Place the MCU's bypass capacitors directly beside the supply and ground pins, use short ground-return paths, and confirm required capacitor values, voltage tolerance, and maximum supply conditions from the official documentation. No absolute-maximum voltage or detailed current information was available in the verified excerpts.
Preserve a clean 32-LQFP land pattern and follow the manufacturer's package drawing for pad dimensions, solder mask, and exposed or thermal structures. Keep programming and debug test points accessible, route clock-sensitive signals away from switching nodes, and provide an unobstructed thermal path where the package requires it. Because a complete numbered pinout was not supplied, PCB release should not proceed from the package name alone.
Check firmware size and RAM allocation against the verified limits of 8 KB Flash and 1 KB RAM before committing to a design. Include the bootloader, relocation tables, interrupt vectors, library code, stack headroom, and application state in the memory budget. Also avoid assuming that another S08-family controller is interchangeable; verify every power, programming, clock, reset, interrupt, and peripheral signal against the official pin table.
Perform a board-level thermal check for the maximum expected ambient temperature and operating frequency. The verified industrial range ends at +85°C, so junction temperature must remain below the device limit with margin after accounting for self-heating, copper area, enclosure temperature, and neighboring heat sources. The available data does not include thermal resistance or processor power consumption, so a numerical junction-temperature estimate cannot be made from the supplied evidence.
اطلاعات انطباق
The verified distributor excerpts do not state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status. The -40°C to +85°C temperature specification is confirmed, but it does not by itself establish automotive qualification.
