As a direct part of the modern megaAVR family (which includes the 168 and 328P), it utilizes the exact same upgraded silicon architecture, pinout, and advanced peripheral set as the chip found on the Arduino Uno. The only functional difference is that it features a leaner 8KB of Flash memory, making it a highly cost-effective choice for streamlined firmware.\u003c\/p\u003e\n\u003cp data-path-to-node=\"6\" id=\"p-rc_85803391f01a5d9b-293\"\u003eThe \"-20PU\" suffix denotes two highly desirable traits for electronics makers.
