Introduction about AT32UC3A0512

The AT32UC3A is a micro controller known as a reliable chip based on the AVR32 with RISC architecture processor that can be clocked at frequencies up to 66 MHz. AVR32 UC is a good performance 32-bit RISC micro controller core designed for embedded applications, while consuming low power, high code, and high performance density. The processor will now implement a Memory Protection Unit (MPU) and a fast and flexible interrupt controller, which will help in supporting modern operating systems and operating systems in real-time. Higher computing capabilities are achievable using a set of DSP instructions.
Working of AT32UC3A0512

The AT32UC3A integrates on-chip Flash and SRAM for secure and easy access. The device’s direct memory access controller (PDCA) allows data transfer between peripherals and memories without processor intervention. PDCA significantly reduces treatment head when transferring continuous data flows and large between modules within the MCU. PowerManager improves design flexibility and security: the chip Brown-Out Detector monitors the power supply, trails of the CPU of the RC oscillator on-chip or external of oscillator sources, a real-time clock and its associated clock keeps track of the time.

The timer/counter comprises a three-channel timer/counter with 16 identical bits. Each channel can be independently programmed to measure the frequency, the counting of events, the measurement interval, the pulse generator, the delay time, and pulse width modulation. The PWM module offers various independent channels with many configuration options, including polarity, alignment edges, and the waveform non-overlap control. A PWM channel can trigger ADC conversions for loop control implementations closed more accurately. The AT32UC3A also has numerous communication interfaces for intensive communication applications. In addition to standard serial interfaces such as UART, SPI, or TWI, like other interfaces, synchronous flexible Serial controller, USB, and Ethernet MAC are available.

The synchronous serial controller allows easy access to serial communication protocols and audio standards, such as I2S. The Full-Speed ​​USB 2.0 supports multiple USB device interface classes together, thanks to the rich endpoint configuration. On-The-Go (OTG) host interface allows the device like a USB flash drive or USB printer connected directly to the processor. The carrier-independent interface (MII) and Reduced MII (RMII) 10/100 MAC Ethernet module provides on-chip solutions for devices connected to the network. AT32UC3A incorporates on chip debugging, with a track in real-time, full read / write memory access, and more control access to the basic design.

Introduction about ATMEGA32U4

ATMEGA Microcontroller belongs to the AVR microcontroller family, and Atmel Corporation makes it. Also. ATMega Microcontroller is an 8-bit microcontroller with a reduced instruction set (RISC) based on Harvard architecture.
It has standard features such as the ROM chip (Read Only Memory), data RAM (Random Access Memory), data of EEPROM (only programmable electrically erasable memory dead), timers and Ports input/output, as well as additional devices as an analog to digital converters (ADC) interface Access series, etc. They set 120 and several beaches and the program memory of the instruction 4K to 256K bytes.

Two students designed the microcontroller ATMEGA at the Norwegian Institute of Technology (NTH) – Alf Bogen and Vegard-Nigel Wollan. It was then purchased and developed by Atmel Corporation in 1996.

ATMEGA Microcontroller Architecture

As mentioned in the introduction, the ATMEGA microcontroller is based on Harvard architecture, namely the separate data memory and program memory. The memory, also known as program code or program memory name, is random access flash memory (ROM). The size of the program memory is between 8 K to 128 K bytes.

The data memory is divided into three parts – 32 general registers, input/output memory, and internal static random-access memory (SRAM). While the general-purpose registers’ size is fixed, the I / O memory and the internal SRAM size vary from chip to chip.
