Atmel launches 14 new microcontrollers

March 12, 2012 // By Nick Flaherty
Atmel has launched 14 new devices aimed at consumer, industrial and medical applications. New AVR XMEGA C microcontrollers support full speed USB, while new tinyAVR MCUs are aimed at interface control in consumer and industrial designs.

All the devices in the portfolio are designed for the low power consumption using Atmel picoPower technology, operating down to 1.62V while maintaining all functionality and short wake-up times. The AVR MCU portfolio also includes devices that support Atmel QTouch Library for capacitive touch functions.
The AVR XMEGA C 8/16-bit general-purpose MCUs with Full-Speed USB provide the highest Flash and SRAM memory densities with up to 384KB Flash and up to 32KB of SRAM.
The tinyAVR ATtiny1634 MCUs feature multiple easy-to-use digital interfacing options—including more communication interfaces than existing devices in the product line—and up to 16KB Flash memory. This new device is ideal for interfacing and control in industrial and consumer applications.
As the newest member of the tinyAVR MCU family, the ATtiny1634 device is designed for space- and power-constrained interfacing and control applications. The MCU features multiple digital interfacing options, including two full-duplex universal synchronous/asynchronous receiver/transmitters (USARTs), I2C slave interface, serial peripheral interface (SPI) port and a Universal Serial Interface (USI) that works as I2C or a three-wire interface. The device is well suited for advanced portable electronic devices such as smartphones, tablets, and handheld games, and related accessories. Household appliance control and man-machine interface (MMI) systems, as well as smart sensors and co-processors in industrial and communications applications, will also benefit from the ATtiny1634 MCU.
Other key device features include a high-speed 8MHz internal oscillator for accurate (+/- 2%) timing and reliable serial communication in varying environmental conditions as well as QTouch Library support and a 32kHz ultra-low power oscillator and sampled brown-out detector (BOD), which reduce power-down current consumption below 1uA with watchdog timer running and BOD active.
The AVR UC3 L3 devices have more Flash memory, integrated USB controller, I2S support, audio bit-stream digital-to-analog converter (ABDAC) and package options with more pins. With the three new devices available, designers can now implement more advanced algorithms requiring more memory in their low-power applications, such as consumer
