The AT91SAM7L64-AU is a microcontroller developed and released by Atmel Corporation. It\'s a member of the AT91SAM7Lxx family, a 32-bit microcontroller based on the ARM7TDMI core. It combines a large number of features and I/O capabilities along with powerful peripherals into a single low-power, low costing package.

The AT91SAM7L64-AU is designed primarily for embedded applications, such as automotive, consumer, industrial and medical applications. It is an ideal choice for applications requiring an ARM7TDMI-S-based architecture with up to 64Kbytes of embedded Flash memory. With lower power consumption due to its advanced sleep mode, it is a perfect choice for embedded applications needing extended battery life.

The processor of AT91SAM7L64-AU is based on the ARM7TDMI-S core, which uses the Thumb instruction set. It has an operating frequency of 57.6 MHz with a memory protection unit (MPU), a vector exception handling and a cache system. The Flash program memory is 64 Kbytes while the SRAM data memory is 16 Kbytes with 8 Kbytes of SRAM dedicated to the MPU.

The peripheral set of AT91SAM7L64-AU includes two USARTs with support for RS-485, CAN and LIN bus and I/O interfaces, along with a SPI and an I2C bus, and a 10-bit Analog to Digital Converter (ADC). It also has an internal oscillator, a Power Management Controller and a programmable watchdog timer.

The working principle of the AT91SAM7L64-AU is to control the peripherals with the ARM7TDMI-S core which is programmed by the user application. The ARM7TDMI-S core is responsible for fetching and decoding the instructions, executing the instruction and loading the results on the data bus. The program memory holds the user code which is fetched and executed by the ARM7TDMI-S core. The peripherals can then be controlled and manipulated by the user code.

The AT91SAM7L64-AU offers a real-time operation with support for power management and a wide range of peripheral interfaces. Its combination of low-priced performance, high density and large memory capacity makes it ideal for embedded applications. With its wide range of features and I/O capabilities, AT91SAM7L64-AU is an ideal choice for a variety of embedded applications.
