{"product_id":"atsamd21g18a-uut","title":"ATSAMD21G18A-UUT","description":"\u003cp\u003eThe ATSAMD21G18A is an ARM Cortex-M0+ microcontroller in a 45-ball WLCSP. It offers 256KB flash and 32KB SRAM with a 1.62-3.6V supply range. Integrated DMA, I2S, and PWM peripherals make it ideal for space-constrained, low-power applications. The -UUT suffix indicates the wafer-level package for compact designs.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eUltra-compact: WLCSP saves PCB area for miniaturized products.\u003c\/li\u003e\n\u003cli\u003eLow power: 1.62V operation extends battery life in portable devices.\u003c\/li\u003e\n\u003cli\u003eRich peripherals: I2S and DMA reduce CPU load for audio and sensor data.\u003c\/li\u003e\n\u003cli\u003eScalable memory: 256KB flash supports complex application code.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eWearable Health Monitors\u003c\/h3\u003e\u003cp\u003eWLCSP package and 1.62V operation enable ultra-thin designs with coin-cell batteries.\u003c\/p\u003e\u003ch3\u003eIoT Sensor Nodes\u003c\/h3\u003e\u003cp\u003eARM Cortex-M0+ with DMA efficiently handles sensor data while sleeping between reads.\u003c\/p\u003e\u003ch3\u003ePortable Audio Devices\u003c\/h3\u003e\u003cp\u003eI2S interface connects directly to audio codecs for high-fidelity playback.\u003c\/p\u003e\u003ch3\u003eSmart Home Controllers\u003c\/h3\u003e\u003cp\u003e3.6V max voltage allows direct connection to Li-ion batteries without boost converters.\u003c\/p\u003e\u003ch3\u003eIndustrial Sensor Hubs\u003c\/h3\u003e\u003cp\u003e256KB flash stores calibration tables and firmware updates over-the-air.\u003c\/p\u003e\u003ch3\u003eMedical Patch Devices\u003c\/h3\u003e\u003cp\u003eSmall footprint and low power enable disposable, single-use diagnostic patches.\u003c\/p\u003e\u003ctable\u003e\n\u003ccolgroup\u003e\u003ccol\u003e\u003c\/colgroup\u003e \u003ctbody\u003e \u003ctr\u003e \t\u003ctd\u003eProduct attributes\u003c\/td\u003e \t\u003ctd\u003eProperty Value\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \t\u003ctd\u003eManufacturer\u003c\/td\u003e \t\u003ctd\u003eMicrochip Technology\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \t\u003ctd\u003eProduct Series\u003c\/td\u003e \t\u003ctd\u003eSAM D21G, Functional Safety (FuSa)\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \t\u003ctd\u003ePackaging\u003c\/td\u003e \t\u003ctd\u003e | NULL\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \t\u003ctd\u003eCore Processor\u003c\/td\u003e \t\u003ctd\u003eARM® Cortex®-M0+\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \t\u003ctd\u003eCore Size\u003c\/td\u003e \t\u003ctd\u003e32-Bit Single-Core\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \t\u003ctd\u003eSpeed\u003c\/td\u003e \t\u003ctd\u003e48MHz\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \t\u003ctd\u003eConnectivity\u003c\/td\u003e \t\u003ctd\u003eI2C, LINbus, SPI, UART\/USART, USB\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \t\u003ctd\u003ePeripherals\u003c\/td\u003e \t\u003ctd\u003eBrown-out Detect\/Reset, DMA, I2S, POR, PWM, WDT\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \t\u003ctd\u003eNumber of I\/O\u003c\/td\u003e \t\u003ctd\u003e38\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \t\u003ctd\u003eProgram Memory Size\u003c\/td\u003e \t\u003ctd\u003e256KB (256K x 8)\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \t\u003ctd\u003eProgram Memory Type\u003c\/td\u003e \t\u003ctd\u003eFLASH\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \t\u003ctd\u003eEEPROM Size\u003c\/td\u003e \t\u003ctd\u003e-\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \t\u003ctd\u003eRAM Size\u003c\/td\u003e \t\u003ctd\u003e32K x 8\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \t\u003ctd\u003eVoltage - Supply (Vcc\/Vdd)\u003c\/td\u003e \t\u003ctd\u003e1.62V ~ 3.6V\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \t\u003ctd\u003eData Converters\u003c\/td\u003e \t\u003ctd\u003eA\/D 14x12b;
