MICROCHIP ATTINY1616-SNR

The ATtiny1614/1616/1617 are members of the tinyAVR® 1- series of microcontrollers, using the AVR® processor with hardware multiplier, running at up to 20 MHz, with 16 KB Flash, 2 KB of SRAM, and 256 bytes of EEPROM in a 14-, 20- and 24-pin package. The tinyAVR® 1- series uses the latest technologies with a flexible, low-power architecture, including Event System, accurate analog features, and Core Independent Peripherals (CIPs). Capacitive touch interfaces with Driven Shield+ and Boost Mode technologies are supported with the integrated Peripheral Touch Controller (PTC).
