The Microchip Technology ATMEGA4809-AU is an 8-bit AVR RISC microcontroller featuring a 20MHz CMOS core. It offers 49KB of FLASH program memory and 6KB of SRAM, complemented by 256 bytes of Data EEPROM. This device supports multiple communication interfaces including I2C, SPI, and four USARTs. For analog sensing, it is equipped with 16 channels of 10-bit Analog-to-Digital Converters. The ATMEGA4809-AU operates with a supply voltage range of 5.0V to 5.5V and can also function at a minimum supply of 1.8V at 5MHz. Its PQFP48 package, with a terminal pitch of 0.50mm, is suitable for surface-mount applications. Peripherals include Brown-Out Detection (BOD), Comparator, Power-On Reset (POR), Real-Time Clock (RTC), five timers, and a Watchdog Timer (WDT). This microcontroller finds application in industrial automation, consumer electronics, and medical devices.
