Design a Custom BoardAbout This Component
ATtiny406 is an automotive-grade 8-bit microcontroller featuring a 16 MHz AVR CPU with 4 KB Flash, 256 bytes SRAM, and 128 bytes EEPROM. It integrates a 10-bit ADC, UART, SPI, TWI (I2C), timers, watchdog, and event system for low-power embedded applications. Suitable for automotive and IoT systems requiring minimal footprint with extensive peripheral integration.
Package: SOIC-20W (7.5mm wide) · 20 pins
Why does this need a breakout?
The 1.27mm pin pitch makes hand-soldering this 20-pin SOIC challenging and error-prone. A breakout board brings all pins to standard 0.1" spacing, enabling reliable breadboard prototyping and simplifying development of USB-to-UART interfaces without requiring reflow soldering or specialized equipment.
