Build with ATtiny1616 — Datasheet Specs & AI Design Help

00 — Overview

What the ATtiny1616 does

The ATtiny1616/3216 are members of the tinyAVR® 1-series microcontroller family, featuring an AVR® CPU with a hardware multiplier and running at up to 20 MHz. These devices offer 16 or 32 KB of Flash memory, 2 KB of SRAM, and 256 bytes of EEPROM within a 20-pin package. Key specifications include a 20 MHz clock speed, 10,000 Flash write cycles, and 100,000 EEPROM erase cycles. The parts support three sleep modes, two 10-bit ADCs, and a Peripheral Touch Controller for capacitive sensing. They operate across temperature ranges from -40°C to 105°C or 125°C and are suitable for applications requiring low power, precise analog features, and integrated peripherals like timers, USART, and SPI interfaces.
