Design a Custom BoardAbout This Component
ATtiny3224 is a low-power 8-bit AVR microcontroller running at up to 20 MHz with 32 KB Flash, 3 KB SRAM, and 256B EEPROM. It features a hardware multiplier, 12-bit differential ADC with programmable gain amplifier, Event System, and 12 GPIO pins in a 14-pin TSSOP package. Ideal for embedded control applications, IoT devices, and power-sensitive designs requiring flexible peripheral integration.
Package: TSSOP-14 (4.4×5mm) · 14 pins
Why does this need a breakout?
The 0.65mm pitch on this 14-pin package makes hand soldering tedious and error-prone without magnification and fine tools. A breakout board routes each pin to standard 0.1-inch headers, enabling breadboard prototyping and simplifying connections for LIN transceivers, ADCs, digital potentiometers, and microcontrollers that typically come in this footprint.
