MKM33Z64CLL5R-FR Présentation
A microcontroller is a programmable system-on-chip that integrates a processor core, nonvolatile program memory, volatile data memory, peripherals, and communication interfaces on one semiconductor device. The MKM33Z64CLL5R-FR belongs to the Cortex-M0+ processor class and the Kinetis KM microcontroller family, combining metering-oriented analog and display functions with general embedded-control capabilities.
The supplied source data identifies a 50 MHz ARM Cortex-M0+ core, 64 KB flash, 16 KB SRAM, 68 I/O, segment LCD, and 100-LQFP packaging. Search results also identify I2C, SPI, UART/USART, DMA, LCD, and watchdog-timer peripherals. Its 64 KB program memory supports compact firmware, while the segment-LCD interface reduces the need for external display-control circuitry in metering products.
The 100-LQFP package exposes substantially more I/O than small-lead-count packages, making it useful where sensors, communication interfaces, display segments, metrology inputs, and control outputs require dedicated pins. The verified snippets list 1.8 V, 2.5 V, and 3.3 V operating options, while exact voltage ranges, accuracy, clock-tree details, ADC characteristics, and pin functions remain to be confirmed from the manufacturer documentation.
Typical uses include electricity meters, flow meters, utility measurement terminals, industrial counters, and other precision instrumentation. For these systems, the combination of metering-aware integration, segment-LCD support, serial interfaces, and a 100-pin package can reduce external component count while preserving broad signal-routing flexibility.
Design validation should begin with the exact NXP datasheet and pinout. Confirm operating-voltage limits, ADC and metrology specifications, LCD segment capacity, peripheral pin multiplexing, clock requirements, decoupling, programming, and exposed-pad or thermal details before layout release. Firmware migration also requires checking memory maps, peripherals, interrupts, and package pin assignments.
This page consolidates verified distributor pricing, source links, package information, application guidance, and an honest assessment of replacement availability. It does not invent missing electrical details: unavailable values remain explicitly marked for engineering follow-up.

Applications typiques
MKM33Z64CLL5R-FR convient pour 6 applications: Single-Phase Electricity Meter, Three-Phase Electricity Meter, Flow Meter Controller, Industrial Precision Counter, Utility Meter Communication Hub, Low-Voltage Measurement Instrument.
Single-Phase Electricity Meter
The MKM33Z64CLL5R-FR fits single-phase metering platforms because the verified Kinetis KM family targets one-, two-, and three-phase electricity meters. Its 50 MHz ARM Cortex-M0+ core can supervise measurement timing, filtering, calibration, and communication, while 64 KB flash supports compact application firmware. The 16 KB SRAM provides working memory for data processing, and the segment-LCD interface can drive a local display. With 68 I/O and I2C, SPI, and UART/USART connectivity, the MCU can integrate measurement front ends, tamper inputs, calibration storage, and communications. Final design suitability depends on verifying the official ADC and metrology specifications, voltage limits, accuracy, and applicable safety requirements.
Recommandé
Three-Phase Electricity Meter
The MKM33Z64CLL5R-FR is a candidate for three-phase electricity meters because the verified family description explicitly includes that topology. The 50 MHz Cortex-M0+ core supports real-time control tasks, the 64 KB flash accommodates metering and communications firmware, and the 16 KB SRAM supports buffers and intermediate results. Its 68 I/O in a 100-LQFP package provides more routing flexibility than a small package, while serial interfaces can connect communications or external metering components. The segment-LCD controller reduces display-interface overhead. Engineers must still confirm phase-count-specific resources, analog signal-chain support, accuracy, timing, isolation boundaries, and meter safety certification against the NXP documentation.
Recommandé
Flow Meter Controller
The MKM33Z64CLL5R-FR is suitable as a controller for precision flow meters, an application explicitly associated with the Kinetis KM family. Its 50 MHz core can execute measurement timing, accumulation, diagnostics, and display updates, while 64 KB flash and 16 KB SRAM provide a balanced embedded footprint. The 68 available I/O support pulse inputs, sensor-control signals, alarm inputs, and local indicators, and I2C, SPI, and UART/USART provide options for external converters or communications. The segment-LCD interface is especially useful for compact flow displays. Meter accuracy still depends on the sensor front end, reference quality, clock accuracy, calibration method, and overall system design.
Recommandé
Industrial Precision Counter
The MKM33Z64CLL5R-FR can serve as the control platform for an industrial precision counter where pulse measurement, local display, logging, and communications must be combined in one device. Its verified 50 MHz Cortex-M0+ core provides timing headroom for interrupt handling and debounce logic, while 64 KB flash supports application and communication firmware. The 68 I/O allow direct connection of sensors, status LEDs, control outputs, and communication hardware. Integrated DMA, watchdog, and segment-LCD functions can simplify system organization. Industrial suitability must be evaluated against the verified operating-temperature specification, supply tolerance, EMC requirements, isolation needs, and functional-safety expectations.
Recommandé
Utility Meter Communication Hub
The MKM33Z64CLL5R-FR can support a local utility-meter communications function where metering data must be combined with serial connectivity and a segment display. Its I2C, SPI, and UART/USART peripherals provide several interface choices, while the 50 MHz Cortex-M0+ core can supervise buffering and protocol tasks. The 100-LQFP package offers 68 I/O for status inputs and external interface control, and the 16 KB SRAM can hold short-lived protocol and measurement data. Engineers should use only the interface speeds and electrical levels verified in the official datasheet, then validate timing margins, protocol isolation, surge protection, and long-duration communications reliability in the target utility equipment.
Recommandé
Low-Voltage Measurement Instrument
The MKM33Z64CLL5R-FR fits low-voltage measurement instruments requiring local control, display, and serial connectivity without a high-performance application processor. The verified 1.8 V, 2.5 V, and 3.3 V supply options allow the MCU to match several embedded power architectures, although exact rail limits remain to be checked. Its 50 MHz core and 16 KB SRAM support timing and data processing, while the segment-LCD controller simplifies numeric instrument displays. With 68 I/O, the design can connect sensors, references, buttons, alarms, and communications. Power-consumption figures, ADC accuracy, analog input topology, and operating-temperature limits must be verified before architecture freeze.

Notes de conception
Do not treat the base MKM33Z64CLL5 listing as proof that every package or order-code suffix is interchangeable with MKM33Z64CLL5R-FR. Confirm the complete ordering code, package drawing, pin assignments, temperature grade, and shipping form. The supplied results establish a 100-LQFP device with 68 I/O, but they do not provide a complete authoritative pin table, so release should wait for verification against the current NXP datasheet and package documentation.
The verified evidence lists 1.8 V, 2.5 V, and 3.3 V supply options, but it does not state exact voltage ranges or current consumption. Before designing the power tree, verify core, I/O, analog, and peripheral limits in the manufacturer datasheet. Select decoupling and regulator tolerances only after confirming those rails, and include margin for transients, startup current, analog accuracy, and peripheral loading. Do not infer current ratings from the 50 MHz clock frequency.
The 100-LQFP footprint provides 68 I/O but still requires disciplined assignment of sensitive analog, clock, reset, and serial signals. Begin with the official pin table and alternate-function matrix, place decoupling at the documented pins, and preserve clean return paths for metrology and reference circuitry. The verified data does not include exact analog pin assignments or exposed-pad details, so PCB layout must not be inferred from distributor diagrams alone.
The supplied technical result identifies the family device as not for new designs even though distributor listings show inventory. Treat available stock as a supply condition, not a long-term roadmap guarantee. New programs should request an NXP successor recommendation and migration plan; existing programs should document the exact approved source, traceability, firmware revision, and end-of-life mitigation plan.
Informations de conformité
The supplied verified data does not provide formal RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals declarations. NXP's broad automotive-design wording is not treated as evidence of AEC-Q100 qualification.
