AVR MICROCONTROllE RS 3 2-bit AVR UC3 Microcontrollers Optimized for System Performance True 1.6V operation More MHz per mW Unrivalled DSP performance Peripheral DMA controller www.atmel.com/UC3 page 2 AVR UC3 Fl ASH MICROCONTROll ERS Everywhere You Are AVR Solutions 8- and 32-bit l ow-Power, High-Performance MCUs AVR combines the most code-efficient architecture for C and assembly programming with the ability to tune system parameters throughout the entire life cycle of your key products. No other microcontrollers deliver more computing performance at a lower power consumption. Combined with industry leading development tools and design support, you get to market faster. And once there, you can easily and cost-effectively refine and improve your product offering. Its simple: AVR works across the entire range of applications youre working on, or want to work on. 32-bit AVR UC3 The 32-bit AVR UC3 product family is built on the high-performance 32-bit AVR architecture and optimized for highly integrated applications. The 32-bit AVR UC3 microcontrollers deliver high computational through- put, deterministic real-time control, low power consumption, low system cost, high reliability and ease of use. The 32-bit AVR CPU includes cutting-edge features such as integer and fixed point DSP arithmetic, single-cycle multiply and accumulate instructions, and single-cycle SRAM access. The peripheral DMA controller and multi-layer high-speed bus architecture make the UC3 core ideal for high throughput ap- plications. UC3 devices are perfectly suited for portable and battery-powered applications due to their outstanding low power properties. 8/16-bit AVR XMEGA The AVR XMEGA delivers 16-bit performance and leading low-power features at an 8-bit price point. With a DMA controller, an innovative Event System, crypto engine, and high-speed ADC and DAC, AVR XMEGA pushes the boundaries for high-performance 8/16-bit MCUs. All AVR XMEGA devices are compatible with tinyAVR and megaAVR devices. Within the XMEGA family, devices are 100% code com- patible across all devices from the smallest to the largest. This makes it possible to develop with any XMEGA device, and switch to any other XMEGA device later without having to change any code. This allows multi-project development teams to keep and maintain only one code base and use and re-use this across multiple projects. The result is much faster development and prototyping cycles. 8-bit megaAVR The megaAVR family offers the broadest selection of devices and peripheral options, making them suitable for a wide range of applications. The family contains devices with l CD, USB, CAN, and l IN interfaces, in addition to the standard SPI, UART and I2C interface. Developed for applications that need large amount of program code, megaAVR offers substantial program and data memories. Better still, megaAVR features self-programming flash for fast, secure, cost-effective field upgrades. 8-bit tinyAVR tinyAVR devices are optimized for a wide range of applications that require a small but power- ful microcontroller. They are perfect for size constrained applications and they are often found as glue logic in bigger systems. boards and is available with integrated A/D converter and EEPROM memory. By delivering Flash flexibility at Mask ROM prices, tinyAVR significantly cuts your time to mar - ket, while boosting your bottom line. And theres nothing tiny about that.
