The ATSAMD21J16B-AUT is a 32-bit ARM Cortex-M0+ Voltage Supervisory and System Management Microcontroller from Atmel. This microcontroller can be used in a variety of embedded applications ranging from general purpose to specialized, such as motor control and battery management.

The ATSAMD21J16B-AUT is based on the ARM Cortex-M0+ processor core and features a 32kb flash memory, 1kb SRAM and 16kb SRAM for data and program storage. Integrated peripherals include a UART, an SPI interface, two I2C buses, two 16-bit timers, two 12-bit Analog-to-Digital converters (ADCs), a three-channel analog comparator and a five-channel data capture unit. It also has two independent Voltage Supervisory (VS) channels and an Advanced Real-Time Clock (RTC).

The Voltage Supervisory (VS) channels are used to monitor and protect critical system voltages. They can detect over- and under-voltage conditions as well as voltage transients. They can also detect extremely fast transients, such as electrostatic discharges, and are able to persistently store their status for critical system handler routines even during heavy software activity.

The Advanced Real-Time Clock (RTC) can provide accurate time of day, independence from main system clock and an on-chip temperature sensor. It allows setting alarms, generating periodic interrupts and operating in sustained time-keeping mode. The timekeeping accuracy of the RTC is maintained thanks to an internal digital temperature compensated oscillator (TCXO).

The ATSAMD21J16B-AUT is the perfect microcontroller for embedded systems that need a cost-effective and energy-efficient solution. It can easily interface with other peripherals and efficiently manages power consumption and real-time system resources such as interrupts and interrupts sources. The low-power operation is achieved by two independent low power sleep modes and a number of power reduction features.

In addition, the ATSAMD21J16B-AUT has a comprehensive set of development tools to aid in the development of embedded solutions. These include the Atmel Studio integrated development environment, Atmel Start prototyping platform, Atmel Software Framework libraries and Atmel SAM-BA flashing software.

In conclusion, the ATSAMD21J16B-AUT microcontroller is an ideal choice for a wide range of embedded applications. It is cost-effective, energy-efficient and offers a comprehensive set of features and development tools for quick and efficient prototyping of embedded solutions.
