SAMR21 系列 256 kB 闪存 32 kB SRAM 48 MHz 32-位 微控制器 - QFN-48EP
The is a 32-bit SMART ARM-based Wireless Microcontroller with 256kB flash and 32kB SRAM memory. IEEE 802.15.4 compliant single chip combines an ARM® Cortex®-M0+ based 32-bit microcontroller and best-in-class 2.4GHz RF transceiver. It offers an excellent RF performance, with a link budget of 103dBm while consuming 50% less active current than existing offerings. The device features IEEE 802.15.4 MAC hardware accelerators and automatic transmission modes, wake-on-radio, offers twelve-channel direct memory access DMA controller, up to four configurable SERCOM modules for I²C, SPI and USART and a 128-bit AES crypto engine. The device features further blocks like a Peripheral Touch Controller PTC, Full-Speed USB Device and embedded Host and hardware components to support RF distance measurements. To complement that set the SAM R21 also supports external power amplifiers and antenna diversity.
