ATSAME51J20A-AUT is an 8-bit AVR microcontroller designed by Atmel. It is a typical low-power microcontroller, which is widely used in various embedded projects due to its low power consumption and strong performance. It is used in automotive applications, industrial control, lighting and heating control, smart home and other products application fields.

ATSAME51J20A-AUT is composed of 8-bit AVR central processing unit (CPU) and other application modules such as timer, interrupt controller, analog-to-digital converter (ADC), digital-to-analog converter (DAC), comparator, programmable logic controller (PLC), pulse width modulation (PWM), etc. The ATSAME51J20A-AUT has a wide range of supply voltages from 1.8V to 5.5V, and it operates at a maximum frequency of 48MHz while its power consumption is very low.

The ATSAME51J20A-AUT utilizes a Harvard architecture with separate program and data spaces, and separate memory and peripherals. The CPU has a maximum instruction rate of 1MIPS per MHz, and its 8-bit RISC architecture reduces the instruction set to reduce memory size and power consumption. The design also supports vector table relocation, which makes the system slightly more versatile than systems with fixed programs.

In addition, the ATSAME51J20A-AUT features an on-chip SIMU peripheral controller, which enables multi-stage programming, parallel expansion and more. The on-chip memory includes up to 8Kb of Flash memory, up to 256Kb of SRAM and up to 4Kb of EEPROM, depending on the model. The on-chip features are rounded out with up to 5 USARTs, up to 7 SPIs, up to 2 I2C and more which make it suitable for a wide range of applications.

Regarding working principle, the ATSAME51J20A-AUT can be programmed and troubleshooted through Atmel Studio programming software. Programmers can use this software to write and debug code, to program the microcontroller and to simulate its performance. Basic operations of the microcontroller include sending and receiving data to and from the system, timing and counting, converting analog signals to digital signals, controlling motors and servos, etc. Furthermore, a wide range of application programs and high-level libraries are available to assist users who lack the programming knowledge.

In conclusion, the ATSAME51J20A-AUT is a powerful low-power AVR microcontroller suitable for embedded applications. It is widely used in fields such as automotive, industrial control, lighting and heating control, smart home, and many more. With its versatile features and powerful programming tools, users are able to create amazing projects with ease and flexibility.
