ATSAMD20J15B-MU

ATSAMD20J15B-MU is a SAM D20 series low-power microcontroller using the 32-bit ARM® Cortex® -M0+ processor. The SAM D20 devices operate at a maximum frequency of 48MHz and reach 2.46 CoreMark® /MHz. They are 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. All devices include intelligent and flexible peripherals, Atmel Event System for inter-peripheral signalling, and support for capacitive touch button, slider and wheel user interfaces.
