The ATSAM3S8BA-AU also has a built-in oscillator and tamper detection system, making it an ideal choice for safety-critical applications.

At the heart of the ATSAM3S8BA-AU is a 32-bit ARM Cortex-M3 processor which runs at speeds up to 48MHz. It has 2MB of internal Flash memory, which can be used to store program code, data and configurations. It also has 256KB of SRAM for high-speed operations such as loop processing, data caching and constant look-up. The ATSAM3S8BA-AU has a variety of analog and digital peripherals, such as 12-bit analog-to-digital conversion, 10-bit digital-to-analog converter and controller area network (CAN) bus support. The device also includes a variety of communication interfaces such as serial peripheral, universal serial bus (USB) and Ethernet. The ATSAM3S8BA-AU is also capable of executing up to 32 DMA channels, allowing it to rapidly access and manipulate large amounts of data.

The ATSAM3S8BA-AU is a highly-capable sensor hub microcontroller, containing features specifically designed for automotive applications. It has a built-in temperature sensor and current measurement sensors, as well as an on-chip RTC which can be used to control timing-sensitive operations. The ATSAM3S8BA-AU also supports the FlexRay (FR) communication protocol, which is widely used in automotive applications such as ABS, body control and engine control. It also supports the XMOS processor and the OpenTherm protocol for home automation and industrial automation applications.

The working principle of the ATSAM3S8BA-AU is based on the ARM Cortex-M3 processor, also known as the "Thumb-2" architecture. This processor is an efficient and versatile solution for embedded control applications, and is fully supported by the Atmel Studio development suite. The ATSAM3S8BA-AU is programmed using assembler or C language, and compiled using the AVR Toolchain. The compilation process produces a "hint" which allows the processor to directly access the peripherals and device resources, as well as to initialize them.

When the microcontroller is powered up, its on-chip oscillator starts up and provides the internal clock source. The ATSAM3S8BA-AU then begins executing the code that has been programmed into it, starting with the initializations code provided by the microcontroller manufacturer. Once the microcontroller is initialized, the user can begin controlling peripherals and the I/O pins, as well as performing data processing and control operations. The ATSAM3S8BA-AU can also be used to control external devices, such as actuators, sensors and motor drivers, as well as interfacing to other microcontroller systems.

The ATSAM3S8BA-AU is an excellent choice for embedded control applications due to its wide range of peripherals, fast execution speed and extended temperature range. Its automotive grade construction makes it suitable for use in rugged environments, and its on-chip oscillator and tamper detection system make it a suitable choice for safety-critical applications. The ATSAM3S8BA-AU is also a cost-effective solution due to its low power consumption and high performance. With its wide range of features, the ATSAM3S8BA-AU is an outstanding choice for automotive applications.
