Atmel launches 14 new microcontrollers
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 products. With picoPower technology, the devices deliver true 1.62V to 3.6V operation. The newest devices increase pin count—by adding 64-pin options to the UC3L family for higher connectivity while SleepWalking peripherals reduce power consumption. These are aimed at sensors, capacitive touch remote controls and game pads, portable and battery-operated equipment, human interface devices, board controllers, industrial control systems, communication protocol translators and backlight LED units.
The UC3 D4 entry level 32bit MCUs include a hardware-based QTouch capacitive touch interface and Full-Speed USB. The two new devices available are ideal for high data throughput applications in areas such as USB human interface, biometrics, bridging and industrial control.
“The newest additions to the Atmel AVR MCU family provide design engineers with more options than ever to meet their unique performance, power, price and connectivity requirements,” said Ingar Fredriksen, senior director of AVR products at Atmel. “Whether they need a small and powerful chip for a smartphone or a lot of memory for a utility metering system, designers can count on our AVR MCUs to deliver the functions and features required to innovate and differentiate in these markets.”
All Atmel AVR MCUs are supported by the company’s new Atmel Studio 6 integrated development environment, which now also supports Atmel ARM Cortex-M processor-based MCUs.
In the AVR XMEGA line, the ATxmega384C3, ATxmega256C3, ATxmega192C3 and ATxmega384D3 are sampling now and other devices will begin sampling in Q2 and Q3 2012, with volume shipments to follow. All AVR UC3 L3 and AVR UC3 D4 devices are available for orders. All AVR ATtiny1634 devices are available now, with the exception of the ATTiny1634-UUR, which will be available in Q2 2012. The ATSTK600 kit and socket and routing cards are available at store.atmel.com and from local distributors.
