24-pin QFN package makes single-channel UART industry’s smallest

The XR16L580 single-channel UART is now being offered in a 24-pin QFN—the industry’s smallest form factor, according to Exar. It has a footprint of only 4-mm X 4-mm and a height of 0.9-mm compared with 5-mm X 5-mm X 0.9-mm of the 28-pin and 32-pin QFN devices.
