ATTINY3216-SF Family Name, Microchip ATTINY3216-SF, 8bit AVR Microcontroller, AVR, 20MHz, 32 kB Flash, 20-Pin SOIC

The Microchip tinyAVR® 1-series microcontrollers is 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 pin package. This 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).
