ATmega324PB Microcontrollers

Atmel ATmega324PB Microcontrollers are high-performance microchip picoPower 8-bit AVR® RISC-based microcontroller that combines 32kB ISP flash memory with read-while-write capabilities. These MCUs execute instructions in a single clock cycle and achieve throughputs approaching 1MIPS/MHz, balancing power consumption, and processing speed. The ATmega324PB MCUs operate at a 1.8V to 5.5V supply voltage range and operate within -40ºC to 105ºC temperature range. The ATmega324PB MCUs feature QTouch Peripheral Touch Controller (PTC) that acquires signals to detect the touch on capacitive sensors. These MCUs provide a faster and less complex capacitive touch implementation in any application.
