ATMEGA168-20AUR Description

Short technical summary and product information.

The ATMEGA168-20AUR is an 8-bit AVR microcontroller from Microchip Technology based on the enhanced RISC architecture. It features 16KB of in-system self-programmable Flash memory, 512B of EEPROM, and 1KB of internal SRAM. Operating at a maximum speed of 20 MHz, it delivers up to 20 MIPS throughput. The device includes 23 general-purpose I/O lines, an 8-channel 10-bit ADC, and supports I2C, SPI, and UART/USART connectivity. Peripheral features include two 8-bit and one 16-bit timer/counters, PWM channels, brown-out detection, power-on reset, and a watchdog timer. The microcontroller operates over a supply voltage range of 2.7V to 5.5V and is specified for -40°C to +85°C temperature range. It is supplied in a 32-TQFP (7x7 mm) surface mount package.
