MKM33Z64ACLH5 50MHz 64KB MCU | NXP | Metering
MPN: MKM33Z64ACLH5 ✓ Hoạt độngMKM33Z64ACLH5 Tóm tắt
The Cortex-M0+ MCU belongs to the broader hierarchy of embedded processor, microcontroller, Kinetis microcontroller, and Kinetis KM metrology MCU. Its role is to combine signal acquisition, control, measurement processing, security functions, and communication support in one device. The KM3x family provides active and passive tamper detection with time stamping, a high-precision internal voltage reference with low temperature drift, and an enablement suite described by NXP.
The verified device identity specifies a 50 MHz operating frequency, 64 KB flash, 16 KB SRAM, segment LCD support, and a 64-LQFP package. Supported supply information in the verified distributor data includes 1.8 V, 2.5 V, and 3.3 V operating options. The secure metering and metrology positioning makes the device suitable for energy measurement rather than general-purpose display, motor-control, or high-performance compute applications.
For design work, the key engineering considerations are accurate analog measurement, reference stability, tamper-response behavior, LCD output implementation, firmware protection, and correct PCB layout around the 64-LQFP footprint. The metrology application should validate sensor excitation, ADC accuracy, voltage-reference drift, calibration coefficients, and energy-integrating firmware across the intended temperature range. Because detailed timing, memory-map, electrical-limit, and pin-function values were not included in the supplied verified excerpts, those values must be taken from the official NXP datasheet rather than inferred.
Typical uses include single-phase, two-phase, and three-phase electricity meters, flow meters, load-monitoring instruments, utility metering terminals, and precision sensor systems. The MCU combines security and integrity-module functions with measurement-oriented resources, making it useful when a product needs a dedicated metrology controller rather than a general-purpose MCU.

Ứng dụng tiêu biểu
MKM33Z64ACLH5 phù hợp cho 6 Áp dụngs: Single-Phase Electricity Meter, Two-Phase Electricity Meter, Three-Phase Electricity Meter, Flow Meter Controller, Utility Metering Terminal, Precision Sensor Instrument.
Single-Phase Electricity Meter
The MKM33Z64ACLH5 fits a single-phase electricity meter because the KM3x family is identified by NXP as supporting one-, two-, and three-phase metering architectures. Its 50 MHz Cortex-M0+ core provides deterministic control and measurement processing, while 64 KB flash and 16 KB SRAM provide room for metering firmware and working state. The active and passive tamper-detection functions with time stamping support integrity monitoring in revenue-metering equipment. The high-precision internal voltage reference with low temperature drift is particularly useful when measurement accuracy must remain stable over temperature. A production design should still validate sensor inputs, ADC characteristics, calibration storage, LCD behavior, and applicable metering qualification requirements against the official datasheet.
Được đề xuất
Two-Phase Electricity Meter
A two-phase electricity meter benefits from the MKM33Z64ACLH5 because the KM3x platform is explicitly identified for two-phase metering. The 50 MHz ARM Cortex-M0+ processor can coordinate measurement channels, energy accumulation, tamper handling, and user-interface updates within one embedded controller. Its 64 KB flash and 16 KB SRAM are appropriate starting resources for embedded metering firmware, though exact peripheral mapping must be checked in the manufacturer documentation. The internal low-drift voltage reference supports calibration stability, while active and passive tamper detection with time stamping helps protect energy-accounting integrity. For deployment, validate phase-channel timing, sensor excitation, display mapping, safety behavior, and production calibration across the intended voltage and temperature range.
Được đề xuất
Three-Phase Electricity Meter
The MKM33Z64ACLH5 is suitable for a three-phase electricity meter because the KM3x family supports one-, two-, and three-phase electricity metering. Its 50 MHz Cortex-M0+ core can execute measurement processing and control logic, while 64 KB flash and 16 KB SRAM support compact embedded software. The segment LCD capability is useful for displaying phase status, energy totals, diagnostics, and service information. Tamper detection and timestamp functions provide an integrity foundation for detecting unauthorized enclosure or circuit interference. Because detailed ADC, timer, pin, and electrical parameters are not included in the supplied excerpts, the board designer must verify those items directly from NXP documentation and validate phase accuracy and timing in production.

Flow Meter Controller
The MKM33Z64ACLH5 can serve as a flow-meter controller when the design requires precision measurement processing in a compact embedded system. The 50 MHz Cortex-M0+ core is suitable for handling sensor timing, pulse or analog measurement workflows, diagnostics, and communications, while 16 KB SRAM provides working memory for control state. The internal voltage reference with low temperature drift supports repeatable measurement behavior, and the KM3x family is explicitly associated with flow meters. The designer should confirm the required timer, ADC, sensor-interface, communication, and calibration peripherals in the complete datasheet. Layout must preserve measurement accuracy by isolating sensitive analog paths and minimizing noise near the sensor and reference circuitry.
Được đề xuất
Utility Metering Terminal
The MKM33Z64ACLH5 fits a utility metering terminal where metering control and tamper awareness must coexist in one MCU. The active and passive tamper-detection functions with time stamping support event logging and integrity monitoring, while the high-precision internal voltage reference with low temperature drift supports stable measurement rails and calibration. Segment LCD support can present energy, status, and diagnostic information locally, reducing the need for a separate display controller. The 64 KB flash and 16 KB SRAM provide a compact firmware footprint for embedded meter logic. Product engineering should still validate communications, storage endurance, security configuration, LCD timing, and regulatory requirements for the target market, since those details are not included in the supplied verified excerpts.
Được đề xuất
Precision Sensor Instrument
The MKM33Z64ACLH5 can be used in a precision sensor instrument when an application needs measurement-focused control rather than a general-purpose MCU. Its 50 MHz Cortex-M0+ core supports responsive control loops, the 64 KB flash stores application firmware, and 16 KB SRAM supports buffers, calibration values, and state-machine execution. The low-temperature-drift internal voltage reference is useful for establishing repeatable analog measurements, while segment LCD support can display live sensor values or calibration status. Confirm ADC characteristics, timer resources, analog pins, and reference behavior in the official datasheet before committing to a design. PCB partitioning, grounding, calibration, and environmental testing are essential because MCU specifications alone do not guarantee end-product accuracy.

Ghi chú thiết kế
Use the official NXP datasheet for the exact supply-voltage limits, decoupling requirements, reset behavior, and analog reference connections. The verified distributor data identifies 1.8 V, 2.5 V, and 3.3 V supply options, but it does not provide current ratings or capacitor values. Keep the metering supply path clean, provide local high-frequency bypass, and isolate noisy switching or load-current paths from sensitive measurement nodes.
Treat the analog measurement section as a precision signal path. Route sensor and reference connections away from clocks, LCD drive transitions, switching regulators, and high-current traces. Use a continuous ground reference where the datasheet permits it, minimize loop area around sensitive inputs, and place input filtering close to the MCU pins. Validate the layout with the manufacturer's reference design and calibration procedure where available.
Do not select a replacement from the MPN naming pattern alone. The supplied cross-reference results include MKM33Z64CLH5, MK10DN64VLH5, and MK10DX64VLH5, but they do not prove identical pin assignments or metrology behavior. Before substitution, compare the complete NXP datasheets, package drawings, memory maps, peripheral assignments, security features, supply limits, and application firmware assumptions.
Thông tin tuân thủ
The supplied manufacturer and distributor excerpts do not provide the requested compliance declarations. Verify current RoHS, REACH, lead-free, halogen-free, conflict-minerals, and product-change information directly with NXP.
