ATMEL  ATSAMD20J17A-AU  微控制器, 32位, SAM D系列, ARM 皮质-M0+, 48 MHz, 128 KB, 16 KB, 64 引脚, TQFP

The is a SMART SAMD20 series 32-bit Low-power Microcontroller based on the high-performance ARM Cortex-M0+ RISC processor. It operates at a maximum speed of 48MHz and features 128kB of flash memory and 16kB of SRAM. Peripherals include six serial communication modules SERCOM configurable as UART/USART, eight 16-bit timers/counters, 32-bit real time clock and calendar, 16 PWM channels, one 20-channel 12-bit ADC, one 10-bit DAC and support for up to 256 touch channels. The device operates from 1.62 to 3.63V. SAMD20 microcontrollers are ideally suited for use in mobile devices due to their low current consumption. Sensor fusion processing is a key area where these devices can be used to differentiate products and with extensive range of sensor partners it is easy to add real-time motion processing to enrich the user experience.
