ATMEGA168PB-AU Description

Short technical summary and product information.

The ATMEGA168PB-AU is a high-performance, low-power 8-bit AVR RISC-based microcontroller from Microchip Technology. It features 16KB of in-system self-programmable Flash program memory, 1KB SRAM, and 512B EEPROM. The device operates at a maximum clock frequency of 20 MHz, achieving up to 20 MIPS throughput.

 

This microcontroller includes a rich set of peripherals: two 8-bit timers, one 16-bit timer, 6 PWM channels, an 8-channel 10-bit ADC, and serial communication interfaces including I2C, SPI, and USART. It also supports capacitive touch sensing via QTouch library. The supply voltage range is 1.8V to 5.5V, making it suitable for battery-powered applications.

 

The ATMEGA168PB-AU is available in a 32-TQFP package (7x7 mm) with surface mount mounting. The operating temperature range is -40°C to 105°C as per the datasheet, though some references indicate -40°C to 85°C. It is designed for a wide range of embedded control applications requiring low power and high performance.
