The Microchip SAMS70Q21 devices are members of a flash microcontrollers family based on the high-performance 32-bit ARM Cortex-M7 processor with Floating Point Unit (FPU). These devices operate at up to 300MHz and feature up to 2048 Kbytes of Flash, up to 384 Kbytes of multi-port SRAM and configurable Instruction and Data Tightly Couple Memories to leverage the advanced DSP capabilities of the core. SAMS70Q21 features multiple communication interfaces including a HS USB Host and Device, a HS SDCard/SDIO/MMC interface, USARTs, SPIs and multiple TWIs. Analog features include dual 2Msps 12-bit ADCs with analog front end offering offset and gain error correction, and 2Msps 12-bit DAC.The SAMS70Q21 is available in 144-pin QFP and BGA package options.Note: While there are no plans to change the availability status of Revision A for this device, new designs should use Revision B for prototypes and production.Supported by MPLAB X IDE andMPLAB Harmony.\n类似型号ATSAMS70Q21B-CFN, ATSAMS70J19A-AN, ATSAMS70J19A-ANT, ATSAMS70J19A-MN, ATSAMS70J19A-MNT, ATSAMS70J19B-AN, ATSAMS70J19B-ANT, ATSAMS70J19B-MN, ATSAMS70J20A-AN, ATSAMS70J20A-ANT, ATSAMS70J20A-MN, ATSAMS70Q21A-AN, ATSAMS70Q21A-ANT, ATSAMS70Q21A-CFN, ATSAMS70Q21A-CFNT, ATSAMS70Q21A-CN, ATSAMS70Q21A-CNT, ATSAMS70Q21B-AN, ATSAMS70Q21B-ANT, ATSAMS70Q21B-CFNT, ATSAMS70Q21B-CN, ATSAMS70Q21B-CNT
