ATSAMD21G18A-UUT Product Details

ATSAMD21G18A-UUT Overview


Packaged in a 45-XFBGA, WLCSP format, this MCU is available in a compact size. There are 38 I/Os on the Microcontroller. It is important to note that the Microcontroller has a Surface Mount mounting type. 32-Bit core is the basis for this Microcontroller. This program has a type of memory called FLASH for this MCU's program memory. Temperatures in this range are operated by this Microcontroller. The SAM D21G series includes this electrical component. There is 256KB 256K x 8 bytes of program memory in MCU, which corresponds to the size of the program. With a ARM® Cortex®-M0+ Core processor, MCU is equipped with the latest technology available. This is a MICROCONTROLLER, RISC uPs/uCs/Peripheral IC. During the manufacturing process, 45 terminations were applied to the IC chip. 32-bits are used in Microcontroller. The MCU chip's supply output is 3.3V volts. Currently, MCU chip has YES DMA channels. 256kB memory size belongs to the Chip part. Alternatives can be found by looking at the base part number ATSAMD21G18. In the case of 48MHz frequency operation, it can perform efficiently. There are YES PWM channels on the device. The chip has 45 pins. The clock has 6 timers/counters to keep track of the time. With ARM core architecture, it offers high performance.
