ATtiny102/104 are self-programmable, 8- and 14-pin tinyAVR MCUs


New tinyAVRs deliver industry’s smallest and lowest power 8-bit MCU on the market today with 1KB Flash.


Making its debut at Embedded World 2016, Atmel has returned to its old-school ways with the world’s highest-performance, low-power, 8-bit microcontrollers boasting 1KB Flash memory. The all-new ATtiny102/104 run up to 12MIPS and integrate features previously only available in larger more expensive MCUs, making them ideal for smaller applications including logic replacement and the latest cost-optimized applications in the consumer, industrial and home automation markets.

The majority of today’s 8-bit market growth is coming from applications that previously only required discrete components. With many of these requiring simple intelligent functions such as timing, motor control or on/off functionality, 8-bit MCUs are becoming an essential feature for the personal healthcare, small kitchen appliance and consumer markets.

The ATtiny102/104 provide all the necessary features to help spur the growth in these applications with its small, cost-optimized low-pincount package with just 1KB of Flash memory. These features include self-programming for firmware upgrades, non-volatile data storage, accurate internal oscillator to provide more reliable motor control, high-speed serial communication with USART, operating voltages ranging from 1.8V to 5.5V 10-bit ADC with internal voltage references, and sleep currents at less than 100nA in power down mode with SRAM retention.

“Atmel has already sold more units of its 8-bit AVR core-based MCUs than the 7.4 billion people on Earth,” says Oyvind Strom, Atmel’s Senior Director of MCUs. “We continue to expand our AVR portfolio with the new ATtiny102/104 8-bit MCUs. These are the first two devices in our new tinyAVR portfolio that are packed with features optimized for tiny, compact MCU systems such as LED lighting, fan control and other small applications.”
