MC9S08FL8CLC - 8-Bit 20MHz MCU, 8KB Flash | NXP
MPN: MC9S08FL8CLC ✗ Cuối đờiMC9S08FL8CLC Tóm tắt
An 8-bit microcontroller is a programmable semiconductor containing a central processing unit, memory, and integrated peripherals on one package. The S08 core belongs to the broader microcontroller hierarchy, which includes embedded processors and microcontrollers used for real-time control. Compared with application-specific controllers, the S08 family provides a general-purpose platform that can implement application logic, monitor inputs, control outputs, and manage communications through its available peripherals.
The MC9S08FL8CLC's principal verified characteristics are its S08 instruction set, 8-bit processing width, 20 MHz operating frequency, 8 KB flash memory, 5 V supply designation, and 32-LQFP package. These values make it relevant for compact embedded products that need local control without the memory footprint or processing complexity of a higher-bit MCU. The LQFP package also exposes more I/O than a small leadless package while remaining compatible with conventional leaded PCB assembly processes.
The MC9S08FL8CLC is identified by NXP as an End of Life product, so new designs should account for lifecycle constraints, availability uncertainty, and the possibility of last-time-buy treatment. Its 8 KB flash allocation is relatively modest, requiring compact firmware and disciplined memory planning. At the same time, a 20 MHz clock can support time-sensitive control tasks when the firmware execution time, peripheral timing, and interrupt latency are properly evaluated.
Typical embedded applications include simple industrial control panels, compact appliance controllers, motor or relay sequencing systems, instrumentation interfaces, LED status and lighting controllers, and small sensor-hub devices. In each case, the MCU serves as the system controller rather than as a high-performance communications processor. The available pin count can support external inputs, outputs, and serial interfaces when the required functions are confirmed against the manufacturer pinout and datasheet.
Designers should verify the exact pin assignments, peripheral resources, electrical limits, and programming requirements before layout release. Because the part is end-of-life, production risk should be evaluated alongside software support, second-source availability, and any approved NXP migration path. This page consolidates verified manufacturer and distributor information, lifecycle status, family-level alternatives, and practical design considerations to support sourcing and engineering review.

Ứng dụng tiêu biểu
MC9S08FL8CLC phù hợp cho 6 Áp dụngs: Compact Industrial Control Panels, Appliance and Equipment Controllers, Relay and Sequencer Control, LED Status and Lighting Control, Portable Sensor and Status Nodes, Serial Interface Equipment.
Compact Industrial Control Panels
The MC9S08FL8CLC is appropriate for compact control panels that read discrete inputs, operate relays or indicators, and run deterministic application logic. Its S08 core operates at up to 20 MHz, providing useful execution margin for interrupt-driven tasks while the 8 KB flash budget keeps the firmware footprint controlled. The 32-LQFP package provides a practical leaded footprint for conventional PCB assembly and external I/O expansion. Designers should verify the exact I/O count, timer channels, and electrical limits from the NXP datasheet before assigning panel inputs or outputs.
Được đề xuất
Appliance and Equipment Controllers
The MC9S08FL8CLC can serve as the central controller in a small appliance or laboratory instrument where an 8-bit MCU is sufficient. The verified 20 MHz operating frequency supports time-based sequencing, state-machine control, and periodic service tasks, while 8 KB flash requires concise application code. In a 5 V-oriented design, the controller can supervise switches, indicators, sensors, and safety interlocks. Its End of Life status means the application should include a procurement buffer or a planned migration for future production rather than treating the MCU as a long-lived platform choice.
Được đề xuất
Relay and Sequencer Control
The MC9S08FL8CLC is suitable for relay sequencing, pump interlocks, and small multi-step actuator controllers where deterministic firmware timing is more important than high processor throughput. Its 20 MHz S08 core can execute a compact state machine and service timer events, while the 32-LQFP package exposes the pins needed for control signals and sensing. The 8 KB flash limit favors short, structured code with minimal middleware. Before finalizing drive circuitry, validate every output's voltage, current, and timing specification against the official datasheet and use suitable external transistor or driver stages.
Được đề xuất
LED Status and Lighting Control
The MC9S08FL8CLC can control LED indicators, status displays, and simple lighting sequences in embedded products. The 20 MHz operating speed provides sufficient headroom for multiplexed indicator updates and debounce logic, while 8 KB flash is adequate for compact lookup tables and timing routines when the application remains focused. The 32-LQFP package provides more external connections than a very small leadless MCU, which can simplify routing between indicator outputs and control inputs. Exact current limits and whether a dedicated LED driver is required must be confirmed from the NXP datasheet.
Được đề xuất
Portable Sensor and Status Nodes
The MC9S08FL8CLC can support a compact sensor node that samples inputs, filters measurements, records operating state, and reports results through a serial interface. The S08 core's 20 MHz maximum frequency is useful for periodic acquisition and communication routines, although the 8 KB flash budget requires careful firmware sizing. Its 32-LQFP package is appropriate where a leaded assembly process and moderate I/O count are preferred. Battery-operated designs should confirm active and sleep current from the manufacturer data before estimating operating life because those values were not present in the supplied data.
Được đề xuất
Serial Interface Equipment
The MC9S08FL8CLC is applicable to compact equipment that translates between local controls and a legacy or industrial serial bus. The 20 MHz S08 processor can manage framing, status logic, and configuration, while the 32-LQFP package offers sufficient pins for communications and supervision functions. Firmware designers should use interrupt-driven routines and constrained buffering to preserve performance within the 8 KB flash limit. The exact on-chip UART, SPI, or I2C resources must be verified from the official pin and peripheral tables before selecting a companion transceiver.

Ghi chú thiết kế
Do not assume that another S08 MCU is a drop-in replacement merely because it uses the S08 core. The verified candidates MC9S08FL8CLD and MC9S08FL8CLH use the same 32-LQFP family footprint, but the ordering-code temperature grades differ. Before substitution, compare the official pin table, power and ground assignments, reset behavior, clock source, memory map, peripheral mapping, and programming configuration. The supplied cross-reference results also show larger-package S08 devices that are not PCB-compatible.
Reserve the 32-LQFP land pattern and verify pin 1 orientation against the official package drawing before releasing artwork. Place the MCU close to its supply bypass capacitors and keep high-current switching paths away from sensitive input traces. The verified data confirms a 7 mm x 7 mm LQFP package but does not provide the numbered pinout, exposed-pad arrangement, or recommended land pattern, so those details must come directly from NXP documentation.
The verified 5 V designation identifies the intended supply class, but exact minimum and maximum operating voltages were not supplied. Use the official electrical-characteristics table to select the regulator tolerance, startup ramp, decoupling capacitors, and any brownout behavior. The 8 KB flash budget also means a bootloader, diagnostics, and application code must be size-checked together. Do not infer RAM, EEPROM, or active-current requirements from the distributor summary.
Because NXP identifies MC9S08FL8CLC as End of Life, avoid designing a new platform around unverified remaining inventory. Add a procurement buffer, obtain written supply confirmation, and evaluate an NXP-approved migration or a redesign using a currently supported MCU. Validate the migration toolchain, bootloader, peripheral libraries, pin mapping, timing, and EMC performance rather than assuming source-level compatibility will be sufficient.
