ATSAME70N21B-AN Description

Short technical summary and product information.

The ATSAME70N21B-AN is a high-performance 32-bit microcontroller based on the ARM Cortex-M7 core, operating at up to 300MHz. It integrates 2MB of Flash memory and 384KB of RAM, providing ample storage and processing capability for complex embedded applications.

 

This MCU offers extensive connectivity options including CANbus, Ethernet, I2C, IrDA, LINbus, MMC/SD/SDIO, QSPI, SPI, UART/USART, and USB. On-chip peripherals include brown-out detect/reset, DMA, I2S, POR, PWM, and watchdog timer. Data conversion is handled by a 10-channel 12-bit ADC and a 2-channel 12-bit DAC.

 

The device is supplied in a 100-LQFP package (14x14mm) and supports surface mount assembly. It operates over a supply voltage range of 1.62V to 3.6V and a temperature range of -40°C to 105°C, making it suitable for industrial environments. The internal oscillator eliminates the need for external clock components in many designs.
