The Microchip SAME70J21 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. SAME70J21 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 FS USB Host and Device, USARTs, SPIs and multiple TWIs. Analog features include single 2Msps 12-bit ADCs with analog front end offering offset and gain error correction, and 2Msps 12-bit DAC.
The SAME70J21 is available in 64-pin QFP 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.
