Device Overview

Summary

The ATtiny1626 is a microcontroller featuring the AVR®  CPU with hardware multiplier - running at up to 20MHz and with 16 KB Flash, 2 KB SRAM and 256 bytes of EEPROM in comes in 20-pin VQFN 3 x 3 mm and SOIC packages. 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. 

Additional Features
  • High-Performance AVR RISC CPU with Hardware Multiplier
    • Running at up to 20 MHz
    • Single Cycle I/O Access
    • Two-level Interrupt Controller
    • Sleep modes: Idle, Standby, Power-down
    • 6 channels Event System
    • Configurable Custom Logic (CCL)
    • Single pin programming and debugging interface (UPDI)
  • Analog Features
    • 12-bit Differential ADC with Programmable Gain Amplifier (PGA)
    • Analog Comparator with internal DAC reference
