Description
AI
The ultra-low-power ATSAML22 based Flash microcontrollers (MCU) feature sophisticated power management technologies and consumes 39 µA/MHz (CPU running CoreMark) in active mode and down to 490nA in ultra low-power backup mode with RTC. In addition to ultra-low-power performance, these devices feature Segment LCD controller, tamper detection, smart card interface, Full Speed USB device, Event System and Sleepwalking, 12-bit analog, AES, capacitive touch sensing and much more.
