ATTINY816-MN

The ATtiny417/814/816/817 are members of the tinyAVR 1- series of microcontrollers, using the AVR processor with hardware multiplexer, running at up to 20 MHz, with 4/8 KB Flash, 256/512 bytes of SRAM, and 128 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).
