The Microchip SAME70Q20 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 1024 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. SAME70Q20 features multiple networking/connectivity peripherals, including CAN-FD interface and one 1O/100Mbps Ethernet MAC with specific hardware support for Audio Video Bridging (AVB). Additional communication interfaces include 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 SAME70Q20 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ATSAME70Q20A-CNT, ATSAME70J19A-AN, ATSAME70J19A-ANT, ATSAME70J19B-AN, ATSAME70J19B-ANT, ATSAME70J20A-AN, ATSAME70J20A-ANT, ATSAME70J20B-AN, ATSAME70J20B-ANT, ATSAME70J21A-AN, ATSAME70J21A-ANT, ATSAME70Q20A-AN, ATSAME70Q20A-ANT, ATSAME70Q20A-CFN, ATSAME70Q20A-CFNT, ATSAME70Q20A-CN, ATSAME70Q20B-AN, ATSAME70Q20B-ANT, ATSAME70Q20B-CFN, ATSAME70Q20B-CFNT, ATSAME70Q20B-CN, ATSAME70Q20B-CNT
