ATSAM4N8CA-AUR Description

Short technical summary and product information.

The ATSAM4N8CA-AUR is a 32-bit microcontroller from Microchip Technology built around an ARM Cortex-M4 core. It operates at frequencies up to 100 MHz and provides 512 KB of flash memory and 64 KB of SRAM. The device supports a supply voltage range of 1.62V to 3.6V and an operating temperature range of -40°C to +85°C.

 

Connectivity is handled through I2C, IrDA, SPI, and UART/USART interfaces. The microcontroller includes a comprehensive set of peripherals such as brown-out detect/reset, DMA, POR, PWM, and a watchdog timer. It features 79 I/O lines and integrated analog conversion with a 17-channel 10-bit A/D converter and a single 10-bit D/A converter. An internal oscillator simplifies clock generation.

 

The device is offered in a 100-pin LQFP package (14x14 mm) with surface-mount mounting. This makes it suitable for compact embedded designs. The combination of processing power, memory, and peripheral integration positions the ATSAM4N8CA-AUR for a variety of control and interface applications.
