New York — Atmel Corp. has expanded its 8-bit microcontroller line with a pair of low-power, 14-pin, tinyAVR devices aimed at cost-effective applications, including computer accessories, thermostats, and personal health accessories.
Atmel's latest tinyAVR MCUs include the ATtiny441 and ATtiny841, each of which features a very small 3x3 QFN package, with 4 and 8 KBytes of Flash memory, respectively.
The new devices offer enhanced analog performance, including an A/D converter with calibrated multilevel internal analog reference, with 12 A/D converter channels on a 14-pin device. The ATtiny441 and ATtiny841 were designed with two independent USARTs with wakeup from power-down without data loss, SPI interface, and an I2C slave interface for enhanced communication capabilities.
The ATtiny441 and ATtiny841 also feature flexible clocking options, including a ± 2 percent internal oscillator with fast wakeup, allowing the UARTs to communicate without the need of an external crystal, and to wake up from sleep without data loss.
ATtiny441/841 devices are fully supported by Atmel Studio 6, the integrated development platform (IDP) for developing and debugging Atmel ARM Cortex-M and Atmel AVR MCU-based applications.
To help accelerate ATtiny441/841 AVR MCU designs, the new devices are supported by Atmel's AVR Dragon Board available on the Atmel Online Store for USD $49. The ATtiny841 and ATtiny441 are also supported by the STK600, AVRONE, JTAGICE mkII, JTAGICE3, and AVRISPmkII development tools.
The ATtiny441/841 is available in mass production, and samples are available from Atmel's Sample Center.
