Small Flash AVR MCUs Target Consumer Electronics

Said to be the world's smallest flash AVR microcontroller packages, Atmel's MCUs target applications in the consumer electronics, lighting and industrial control markets. The Atmel ATtiny4, ATtiny5, ATtiny9 and ATtiny10 AVR MCUs come in an ultra-small eight-pad UDFN package. The packages measure 2 x 2 x 0.6mm and weigh less than 8mg to reduce the package size as much as 55 per cent compared to the smallest competitor package, according to the company.

The devices are suited for lightweight and small-form-factor consumer applications, such as mobile phones, toys, toothbrushes and other personal-care and portable electronic products. A powerful AVR MCU can also be integrated into some of the smallest designs. These designs may include the inside of electrical leads and miniature connectors, printer heads and other applications such as inside clothing fabrics, plastic cover sheets or shells.

Ingar Fredriksen, AVR product marketing director, said: 'The devices deliver six times higher processing speed than the closest competitor. This range is based on Atmel's low-power Picopower technology, which enables any AVR microcontroller to operate at the industry's lowest power consumption at 650nA with an RTC running and less than 100nA in power down. These products also contain a rich feature set to execute code up to 12MIPS at 12MHz.
