ATSAMD20J16A-AU Description

Short technical summary and product information.

The ATSAMD20J16A-AU is a 32-bit microcontroller from Atmel based on the ARM Cortex-M0+ processor core. It operates at a maximum speed of 48MHz and includes 64KB of program memory (flash) and 8KB of RAM. The device provides 52 I/O lines for interfacing with external components.

 

The microcontroller supports a supply voltage range from 1.62V to 3.6V and is specified for an operating temperature range of -40°C to +85°C. It includes peripherals such as brown-out detection and reset, power-on reset (POR), and a watchdog timer (WDT). For connectivity, the device features I2C, SPI, and UART/USART interfaces. It also includes an analog-to-digital converter with 20 channels of 12-bit resolution and a digital-to-analog converter with 10-bit resolution.

 

Packaged in a 64-TQFP (10x10) surface-mount package, the ATSAMD20J16A-AU is suitable for embedded control applications requiring moderate processing power and a rich set of analog and digital peripherals.
