MKM33Z64CLH5 Обзор
A microcontroller, or MCU, is a compact embedded-computing device integrating a processor core, nonvolatile program memory, data memory, peripherals, and communication interfaces on one semiconductor. The MKM33Z64CLH5 belongs to the Kinetis KM family, optimized for metrology and precision measurement. Its metrology-oriented integration can reduce the need for separate measurement, display, and communication components in utility-meter and industrial sensor products.
Verified product information identifies 64 KB of flash, 16 KB of SRAM in one indexed datasheet result, and 8 KB of RAM in the NXP product-page result. Because these source snippets differ, downstream firmware planning must confirm the actual memory map and relevant orderable-device data. The device is identified as a 32-bit microcontroller with an Arm Cortex-M0+ processor operating at up to 50 MHz in the DigiKey listing.
The MKM33Z64CLH5 is particularly relevant to electricity meters, flow meters, and precision measurement instruments. Its metrology MCU positioning supports designs that need deterministic embedded control alongside measurement front-end processing and communication. The exact ADC, timer, display, communications, voltage, temperature, and package dimensions are not fully present in the supplied source data and must be checked against the manufacturer documentation before schematic or firmware release.
For new designs, engineers should verify the memory configuration, pin multiplexing, LCD segment capability, clock limits, electrical operating range, and programming requirements directly with NXP. The verified sources identify the device as a 64-LQFP industrial-grade component in distributor indexing, but current stock, lifecycle status, pricing, and detailed electrical limits were not supplied.
This page consolidates verified distributor descriptions, official NXP product information, package identity, source differences, and engineering selection considerations. It does not infer missing electrical specifications or treat functional metrology MCUs as pin-compatible alternatives without verified evidence.

Типичное применение
MKM33Z64CLH5 подходит для 6 применениеs: Single-Phase Electricity Meter, Two-Phase Electricity Meter, Three-Phase Electricity Meter, Flow Meter Controller, Precision Measurement Instrument, Segment LCD Metering Interface.
Single-Phase Electricity Meter
The MKM33Z64CLH5 fits single-phase electricity-meter concepts because its Kinetis KM family is explicitly identified for this application. The 32-bit Arm Cortex-M0+ core, verified 64 KB flash program memory, and segment LCD support provide a base for measurement processing, calibration, display output, and communications. Its 64-LQFP 10 mm × 10 mm package offers 64 pins for mixed analog and digital connectivity. Before schematic release, verify ADC accuracy, metering-specific timers, input ranges, clock limits, and pin multiplexing because those values are not included in the supplied snippets.
Рекомендуется
Two-Phase Electricity Meter
The Kinetis KM family positioning cited in the verified data extends to two-phase electricity meters, making the MKM33Z64CLH5 relevant for dual-channel energy-measurement designs. Its Cortex-M0+ architecture supports compact embedded control, while 64 KB flash can hold application firmware, calibration tables, and communications logic. The 64-LQFP package provides more I/O density than a small leadless package. Final suitability depends on confirming simultaneous sampling resources, metering accuracy, oscillator requirements, and supported display or communications interfaces in the authoritative NXP documentation.
Рекомендуется
Three-Phase Electricity Meter
The supplied family description identifies the Kinetis KM devices as enabling three-phase electricity meters, so the MKM33Z64CLH5 is architecturally relevant to polyphase metering. Its 32-bit Cortex-M0+ core and 64 KB flash can support measurement scheduling, tariff logic, event logging, and display control, while the 64-LQFP footprint exposes a substantial pin count. Engineers must confirm converter-interface requirements, isolation boundaries, ADC synchronization, temperature compensation, and regulatory accuracy; none of those detailed specifications can be verified from the supplied result snippets.
Рекомендуется
Flow Meter Controller
The MKM33Z64CLH5 is suitable for consideration in precision flow-meter controllers because the verified family description explicitly names flow meters alongside electricity meters. Its Cortex-M0+ processor supports embedded measurement logic, compensation, accumulation, alarms, and communications within a compact embedded design. The 64-LQFP package offers ample external connectivity compared with a small microcontroller package, and the segment LCD capability can simplify local readout designs. Validate transducer interfaces, timer capture, ADC performance, supply range, and low-power requirements before component approval.
Рекомендуется
Precision Measurement Instrument
The metrology-focused Kinetis KM architecture gives the MKM33Z64CLH5 a logical role in precision measurement instruments that combine sensor conditioning, control, calibration, and a local display. Its verified 32-bit Arm Cortex-M0+ core and 64 KB flash provide embedded processing, while the 64-LQFP format supports a broad mix of sensor, communications, and display connections. The design must confirm the MCU’s analog conversion performance, oscillator accuracy, voltage range, temperature limits, and required interfaces. A conservative 48 MHz clock ceiling should be used until the conflicting 48 MHz and 50 MHz source claims are reconciled.
Рекомендуется
Segment LCD Metering Interface
The segment LCD feature identified for the MKM33Z64CLH5 supports direct use in metering products with local numeric or status displays. Combining a metrology microcontroller and segment-display control in one 64-LQFP device can simplify a one- or two-phase meter layout while preserving a dedicated MCU core for measurement and calibration. The available segment count, common-drive scheme, frame rate, and alternate multiplexing are not supplied and therefore cannot be assumed. Confirm display voltage, glass pin requirements, unused segment behavior, and package-level multiplexing in the manufacturer datasheet before laying out the PCB.

Заметки по проектированию
Do not build production firmware around the conflicting memory and frequency snippets. The official NXP result lists 8 KB RAM and up to 48 MHz, while other indexed results claim 16 KB SRAM and DigiKey lists 50 MHz. Use the lowest stated frequency during initial planning and verify the exact order-code documentation before linker scripts, clock trees, timing constants, or register definitions are finalized.
Treat all 64 LQFP positions as unresolved until the official package drawing is checked. Assign power, ground, analog inputs, LCD outputs, programming signals, and communications only after reviewing the authoritative pin multiplexing table. Preserve decoupling flexibility, maintain clean analog routing, and provide unobstructed access to programming and debug interfaces because their exact pin assignments were not included in the supplied data.
Electricity-meter and precision-measurement boards should separate sensitive analog inputs from LCD drive, programming, and switching-supply paths. Use a continuous ground reference, minimize high-impedance sensor traces, place filtering close to the measurement interface, and keep LCD and communication return currents away from reference nodes. Exact time constants cannot be derived because ADC, impedance, sampling, and filter specifications are unavailable in the supplied sources.
Информация о соответствии
The supplied verified data does not contain explicit environmental or automotive compliance declarations. Industrial temperature-grade indexing does not establish RoHS, REACH, or AEC-Q100 status. AEC-Q100 is treated as not applicable because the indexed target is an industrial MCU, not an automotive-qualified device.
