ATTINY3217-MF

ATtiny3216/3217 tinyAVR 1-series Introduction The ATtiny3216/3217 are members of the tinyAVR 1-series of microcontrollers, using the AVR processor with hardware multiplier, running at up to 20 MHz, with 32 KB Flash, 2 KB of SRAM, and 256 bytes of EEPROM in a 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). Attention: Automotive products are documented in separate data sheets.
