Overview
The SC16IS762IBS,151 from NXP USA Inc. is a dual-channel high-performance UART (Universal Asynchronous Receiver-Transmitter) that integrates an I²C-bus/SPI interface. This device is designed to provide seamless protocol conversion from I²C-bus/SPI to RS-232/RS-485 and supports data rates up to 5 Mbit/s. It is particularly suited for hand-held, battery-operated applications due to its low operating and sleeping current. The SC16IS762IBS,151 comes in a compact HVQFN32 package, making it ideal for space-constrained designs.
