Microchip Technology's ATMEGA4808-XU is an 8-bit RISC microcontroller featuring an AVR RISC CPU capable of operating at up to 20MHz. This CMOS device, housed in a 28-pin PDSO package, offers 49152 bytes of FLASH program memory and 6144 bytes of SRAM, alongside 256 bytes of Data EEPROM. Peripherals include four timers, a real-time clock (RTC), a brown-out detector (BOD), a power-on reset (POR), and a watchdog timer (WDT). Connectivity options include I2C, SPI, and three USARTs. The device supports up to 23 I/O lines and incorporates an 8-channel, 10-bit Analog-to-Digital Converter (ADC). It operates within a supply voltage range of 1.8V to 5.5V, with a minimum supply of 1.8V at 5MHz. Applications span industrial automation, consumer electronics, and IoT devices.
