ATtiny4/5/9/10 MCUs

Atmel Corp. is offering what is claimed to be the smallest flash AVR microcontroller package. The Atmel ATtiny4, ATtiny5, ATtiny9 and ATtiny10 AVR microcontroller (MCU) come in an ultrasmall 8-pad UDFN package, with a dimension of only 2mm x 2mm x 0.6mm, and weighing less than 8mg to reduce the package size as much as 55 percent compared to the market's smallest package offering available today. These products target applications in the consumer electronics, lighting and industrial control markets. The new devices are well-suited for lightweight and small form factor consumer applications, such as cellphones, toys, tooth brushes and other personal care and portable electronic products.

"The smaller, lighter, faster and low-power microcontrollers from the Atmel ATtiny4/5/9/10 family also make it possible to integrate a powerful AVR MCU in 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," said Ingar Fredriksen, AVR product marketing director. "In addition to being 55 percent smaller than any other 6-/8-pin flash microcontroller in the market, the ATtiny4, ATtiny5, ATtiny9 and ATtiny10 devices deliver 6x higher processing speed than the closest competitor."

This family is based on Atmel's patented low-power picoPower technology which enables any AVR MCU to operate at the lowest power consumption at 650nA, with a RTC running, and less than 100nA in power down. These products also contain a rich feature set to execute code up to 12 MIPS at 12MHz.

The Atmel ATtiny4, ATtiny5, ATtiny9 and ATtiny10 are available now. Volume pricing starts at $0.52 for 10,000 quantities.
