ATSAMD21J18A-AUT

ATSAMD21J18A-AUT is a SAM D21/DA1 low-power, 32-bit Cortex-M0+ MCU with advanced analog and PWM. It is designed for simple and intuitive migration with identical peripheral modules, hex-compatible code, identical linear address map, and pin-compatible migration paths between all devices in the product series. It includes intelligent and flexible peripherals, an event system for inter-peripheral signaling, and support for capacitive touch buttons, sliders, and wheel user interfaces. It has accurate and low-power external and internal oscillators. Different clock domains can be independently configured to run at different frequencies, enabling power saving by running each peripheral at its optimal clock frequency, and thus maintaining a high CPU frequency while reducing power consumption. It is supported with a full suite of program and system development tools, including C compilers, macro assemblers, program debugger/simulators, programmers, and evaluation kits.
