Microchip AVR® MCUs
Microchip’s 8-bit AVR® microcontrollers (MCUs) are an excellent choice for designers of a wide variety of embedded systems. These devices offer a unique combination of performance, power efficiency and design flexibility. Optimized to reduce development time, they are based on the industry’s most code-efficient architecture for C and assembly programming.
Industry-leading development tools and design support further help you get your design to market faster. Plus, once your products have launched, the large AVR family allows you to reuse your knowledge to improve and enhance your offerings, making it easy and cost-effective to expand into new markets.

AVR Product Families
tinyAVR microcontrollers (MCUs) are optimized for applications that require performance, power efficiency and ease of use in a small package. All tinyAVR devices are based on the same architecture and compatible with other AVR® devices. The integrated ADC, DAC, Comparators, EEPROM memory and brown-out detector let you build applications without adding external components. tinyAVR devices also offer Flash memory and on-chip debug for fast, secure and cost-effective in-circuit upgrades that significantly cut your time to market.
megaAVR microcontrollers (MCUs) are the ideal choice for designs that need some extra muscle. For applications requiring large amounts of code, megaAVR devices offer substantial program and data memories with performance up to 20 MIPS. Meanwhile, innovative Atmel picoPower® technology helps minimize power consumption. All megaAVR devices offer self-programmability for fast, secure, cost-effective in-circuit upgrades. You can even upgrade the Flash memory while running your application.
AVR® XMEGA MCUs
AVR XMEGA microcontrollers deliver the best possible combination of real-time performance, high integration and low power consumption for 8/16-bit MCU applications.
8-bit PIC® MCUs
PIC® microcontrollers are finding their way into new applications like smartphones, audio accessories, video gaming peripherals and advanced medical devices. Microchip provides solutions for the entire performance range of 8-bit microcontrollers, with easy-to-use development tools, complete technical documentation and post design-in support through a global sales and distribution network.
