The Microchip microcontroller is using the AVR® processor with hardware multiplier, 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).
