The part integrates a 16-bit SAR ADC, a 24-bit sigma-delta ADC, and a 6-bit DAC — a mixed-signal front end that typically needs an external converter on competing MCUs. An on-chip LCD controller drives segment displays directly, saving a glass-driver IC and the associated board area. Rated for -40°C to 85°C ambient, the MKM33Z64CLL5R-FR suits factory-floor controllers, outdoor telecom nodes, and panel meters. The supply range spans 1.71 V to 3.6 V on Vdd. Serial interfaces include I²C, SPI, and UART/USART — the standard set for sensor aggregation and Modbus RTU links. DMA offloads data movement from the CPU core, useful when the sigma-delta ADC runs continuous conversions. The watchdog timer (WDT) provides a supervised reset path for unattended equipment. NXP lists the MKM33Z64CLL5R-FR as Active on the product lifecycle.","metaTitle":"NXP MKM33Z64CLL5R-FR Kinetis KM MCU, 50MHz ARM Cortex-M0+","metaDescription":"NXP MKM33Z64CLL5R-FR Kinetis KM 32-bit MCU: 50MHz ARM Cortex-M0+, 64KB Flash, 16KB RAM, 24-bit sigma-delta ADC, LCD controller.","metaKeywords":null},"attributes":{"series":"Kinetis KM","packageCase":null,"mountingType":null,"rohsStatus":"Not applicable","productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Speed":"50MHz","Series":"Kinetis KM","Package":"Bulk","RAM Size":"16K x 8","Core Size":"32-Bit Single-Core","Peripherals":"DMA, LCD, WDT","Connectivity":"I²C, SPI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"68","Core Processor":"ARM® Cortex®-M0+","Package / Case":"100-LQFP","Data Converters":"A/D 16b SAR, 24b Sigma-Delta; D/A 6b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Program Memory Size":"64KB (64K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"100-LQFP (14x14)","Voltage - Supply (Vcc/Vdd)":"1.71V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.48","stockQuantity":0,"priceTiers":[{"qty":55,"price":"$5.48000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/e9f1ac4922fdc64236ad60331a53732f.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the closest functional second-source for MKM33Z64CLL5R-FR?","answer":"The MK51DX128CMC7 is a Kinetis-series peer with a 72 MHz Cortex-M4 core and larger memory, but it is not a pin-compatible or drop-in replacement.
