Microcontrollers

The ATMEGA808-AU is a microcontroller unit (MCU) developed by Microchip Technology. It belongs to the ATmega family of 8-bit AVR microcontrollers, which are widely used in various embedded systems and applications.

Description:

The ATMEGA808-AU is a low-power, high-performance 8-bit microcontroller based on the enhanced AVR core. It operates at a frequency of up to 20 MHz and features 8 KB of In-System Programmable Flash memory, 2 KB of In-System Programmable SRAM, and 512 B of EEPROM. The MCU is available in a 28-pin Atmel QFN package.

Features:

1. 8-bit AVR enhanced RISC architecture for higher code density and better performance.
2. Up to 20 MHz operating frequency.
3. 8 KB of In-System Programmable Flash memory with read-while-write capability.
4. 2 KB of In-System Programmable SRAM.
5. 512 B of EEPROM.
6. 23 general-purpose I/O lines with optional internal pull-up resistors.
7. 32 general-purpose working registers.
8. Nested interrupt controller with 16 priority levels.
9. On-chip debug system with JTAG and SPI interface.
10. Internal calibrated oscillator with different options for frequency range.
11. Power-saving features, including system clock frequency division, power reduction, and sleep modes.
12. Integrated peripherals, such as a USART, a 16-bit timer/counter with PWM and input capture, and a 10-bit ADC.
