Atmel has introduced two new high-performance, low-power 8-bit MCUs which feature 1kbyte of on-board Flash memory and 32bytes of SRAM.

The new ATtiny102 and ATtiny104 MCUs run at up to 12MIPS and integrate features previously only available in larger, more expensive MCUs. The smallest package style of the new MCUs is an eight-pin UDFN measuring just 3mm x 2mm x 0.6mm.

The ATtiny MCUs, which are based on an 8-bit AVR processor core, are aimed at applications that previously only used discrete components. Many of these new applications require simple intelligent functions such as timing and motor control or on/off functionality: the small, cost-optimized ATtiny MCUs provide the range of integrated features called for in these systems. The key features in the ATtiny102 and ATtiny104 include non-volatile data storage, an accurate internal oscillator to provide for reliable motor control, and high-speed serial communication over a USART interface. Operating from an input-voltage range of 1.8V-5.5V, the ATtiny10x MCUs draw a sleep current of less than 100nA in power-down mode with SRAM retention.
