ATtiny3217 Tinyavr microcontrollers

For sensor nodes applications


The ATtiny3217 is the lead device in the tinyAVR 1-series. Ideal for sensor nodes applications, the ATtiny3217 features two 10-bit Analog-to-Digital Converter (ADC) which provides accurate and timely analog signal acquisitions. The ATtiny3217 comes in a 4 mm x 4 mm 24-pin VQFN package, and will be available in two temperature grades, 105°C and 125°C. Following shortly, the ATtiny3216 in SOIC 20-pin package will be available. The ATtiny3217 and ATtiny3216 products are similar to the already available ATtiny1617 and ATtiny1616, but with more memory.
