ATmega644-20PU

8-Bit megaAVR Microcontrollers, 32KB to 256KB Flash
Here at RS Components we have various megaAVR 8-bit microcontrollers from Atmel. Each of the microcontrollers is based on an enhanced RISC architecture and feature QTouch library support. All the microcontroller types have varying Kb of In-System Programmable Flash, EEPROM and SRAM as well as varying pin and package types.<BR/><BR/><B>Types of megaAVR 8-bit microcontrollers</B><BR/>•ATmega32<BR/>•ATmega64<BR/>•ATmega128<BR/>•ATmega324<BR/>•ATmega325<BR/>•ATmega406<BR/>•ATmega640<BR/>•ATmega644<BR/>•ATmega645<BR/>•ATmega1280<BR/>•ATmega1281<BR/>•ATmega1284<BR/>•ATmega2560<BR/>•ATmega2561<BR/>•ATmega3250<BR/>•ATmega6450
