Quality Control: Learn More

The Microchip Technology AVR® ATmega ATMEGA48-20MI is an 8-bit AVR microcontroller featuring a 20MHz core clock speed. This device offers 4KB of FLASH program memory (organized as 2K x 16) and 512 bytes of SRAM, complemented by 256 bytes of EEPROM. It supports multiple communication protocols including I2C, SPI, and UART/USART, and integrates eight 10-bit analog-to-digital converters. Peripherals include brown-out detection, power-on reset, pulse-width modulation (PWM) capabilities, and a watchdog timer. With 23 general-purpose I/O pins, the ATMEGA48-20MI is suitable for applications across industrial automation, consumer electronics, and automotive systems. It operates within a voltage range of 2.7V to 5.5V and is housed in a 32-VQFN (5x5) package, employing surface mount technology. The internal oscillator provides a reliable clock source.
