Tiny UART Integrates Oscillator

Embarking as the industry's fastest, and smallest serial UART to communicate over an SPI/I²C interface, the MAX3107 delivers data rates up to 24 Mb/s and measures 3.5 mm x 3.5 mm in a TQFN. Also, the UART is allegedly the industry’s first to integrate an oscillator to reduce the need for external clocking. The device interfaces an SPI or I²C synchronous serial microprocessor bus to asynchronous, serial data-communication ports, i.e., RS-485, RS-232, PROFIBUS, or IrDA. Its receiver and transmitter each have a 128-word-deep FIFO that reduces the intervals a host processor must dedicate for high-speed, high-volume data transfers. The MAX3107 operates from 2.35V to 3.6V and over an industrial temperature range from -40°C to +85°C. Price is $3.25 each/1,000. MAXIM INTEGRATED PRODUCTS, Sunnyvale, CA. (800) 998-8800.
