Design a Custom BoardAbout This Component
Low-power 8-bit AVR microcontroller with 2KB flash memory, 128B SRAM, and 128B EEPROM. Features 6 I/O lines, 10-bit ADC with 4 single-ended or 2 differential channels, two 8-bit timers with PWM outputs, USI serial interface, and internal oscillator. Operating range 2.7–5.5V at up to 20MHz, ideal for embedded control and sensor applications.
Package: SOICW-8 (5.3mm wide) · 8 pins
Why does this need a breakout?
This SOIC-8 package is too small to hand-solder reliably and incompatible with breadboards. A breakout board brings 1.27mm pitch pins to standard 0.1-inch spacing, enabling prototyping without specialized equipment. Ideal for memory and sensor ICs that demand convenient development while preserving the compact footprint.
