Microchip Technology ATmega4808 series 8-bit RISC microcontroller, part number ATMEGA4808-AU. This device features an AVR RISC CPU operating at up to 20MHz with 49152 bytes of FLASH program memory and 6144 bytes of RAM. It offers extensive peripheral support including up to 27 I/O lines, four timers, a real-time clock, a watchdog timer, and programmable brown-out and power-on reset circuits. Connectivity options include I2C, SPI, and three USARTs. The ATMEGA4808-AU includes 12 channels of 10-bit Analog-to-Digital converters. It operates from a 5.0V nominal supply voltage and is packaged in a 32-lead TQFP (Thin Quad Flat Pack). This component finds application in industrial automation, consumer electronics, and automotive systems.
