Microchip Launches New Generation of 8-bit AVR MCUs with Core Independent Peripherals

The new ATtiny817/816/814/417 devices provide all the right features to help drive product innovation including small, low pin count and feature-rich packaging in 4 KB or 8 KB of Flash memory. Other integrated features include a CIP called Peripheral Touch Controller (PTC); Event system for peripheral co-operation, custom programmable logic blocks; self-programming flash for firmware upgrades; non-volatile data storage; 20 MHz internal oscillator; high-speed serial communication with USART; operating voltages ranging from 1.8 V to 5.5 V, 10-bit ADC with internal voltage references; and sleep currents at less than 100 nA in power down mode with SRAM retention.
