+ | There are many great brands and families of microcontrollers, including the "PIC" line from Microchip, the MSP430 family of microcontrollers from Texas Instruments, and many others. This | ||

===== AVR families ===== | ===== AVR families ===== | ||
+ | |||
+ | All AVR chips can be divided into 4 main groups. Only 2 are available in DIP formats. | ||
+ | |||
+ | ==== ATtiny ==== | ||
+ | |||
+ | Tiny's are the low-cost branch of the AVR family. | ||
+ | |||
+ | ==== ATmega ==== | ||
+ | |||
+ | Mega's are the most popular AVR family with hobbyists. Most Arduino model are powered with an ATmega. | ||
+ | |||
+ | ==== xMEGA ==== | ||
+ | |||
+ | The xMEGA is somewhat newer family that has not yet made a huge impact in the hobbyist embedded electronics world. | ||
+ | |||
+ | ==== AVR32 ==== | ||
+ | |||
+ | The AVR32 family of chips have little to do with the 8 bit families, other than branding. | ||
