Device Overview

Summary

The ATtiny3227 is a microcontroller featuring the AVR®  CPU with hardware multiplier, running at up to 20 MHz, and with 32 KB Flash, 3 KB SRAM and 256B of EEPROM in a 24-pin VQFN 4 x 4 mm package. The family uses the latest Core Independent Peripherals with low-power features, including Event System, intelligent analog and advanced peripherals.

The new 12-bit ADC offers true differential measuring capabilities with optional  hardware accumulation of up to 1024 samples, which effectively gives up to 17-bits resolution. With sampling rates up to 375 ksps, the analog data is available very rapidly. The Programmable Gain Amplifier (PGA) for the ADC can amplify single-ended and differential analog inputs to make it possible to measure even small amplitude signals efficiently.
