Microchip Technology, Inc. Microcontrollers ATSAMS70Q21B-CFNT

The ATSAMS70Q21B-CFNT is a 32-bit microcontroller based on the Arm Cortex-M7 architecture, capable of operating at speeds up to 300 MHz. It features 2 MB of embedded Flash memory and 384 KB of Multi-port SRAM, along with a 16 KB instruction cache and a 16 KB data cache, both equipped with Error Code Correction (ECC). The microcontroller includes a hardware Floating Point Unit (FPU) supporting both single and double precision, and a Memory Protection Unit (MPU) with 16 zones for enhanced security. This device supports a variety of peripherals, including a high-speed USB 2.0 interface, Ethernet MAC for 10/100 Mbps connections, and multiple communication interfaces such as USART, SPI, and I2C. It also features advanced analog capabilities with dual 12-bit Digital-to-Analog Converters (DACs) and two Analog Front-End Controllers (AFECs) for high-speed data acquisition. Power management is robust, with an embedded voltage regulator, multiple low-power modes, and a real-time clock (RTC) that operates in backup mode with minimal power consumption. The ATSAMS70Q21B-CFNT is available in various package options, including LQFP and BGA formats, making it suitable for a wide range of applications in industrial and automotive environments.
