About this item

The ATmega16A-PU is a powerful and versatile 8-bit microcontroller from Atmel's AVR family, widely used in embedded systems and electronics projects. It features the enhanced AVR RISC architecture, which combines high performance and low power consumption. The microcontroller operates at clock speeds up to 16 MHz, enabling fast and efficient execution of instructions. With 16 KB of Flash memory, the ATmega16A-PU provides ample space for program storage, making it suitable for complex applications. It also includes 1 KB of SRAM for data storage and 512 bytes of EEPROM for non-volatile memory needs. This combination allows for flexible data handling during runtime and persistent data retention when powered off. The microcontroller offers a rich set of peripherals, including 32 programmable I/O pins, two 8-bit timers, one 16-bit timer, and an 8-channel 10-bit Analog-to-Digital Converter (ADC) for interfacing with analog sensors. It supports multiple communication protocols such as USART, SPI, and I2C, making it ideal for connectivity with various modules and devices. Additional features like internal and external interrupt support, a watchdog timer, and power-saving sleep modes enhance its usability in embedded applications like robotics, automation, and consumer electronics. The ATmega16A-PU is supported by popular development tools such as the Arduino IDE and Atmel Studio, making it accessible for both beginners and professionals.
