Overview
The SC16IS762IPW128, produced by NXP USA Inc., is a dual-channel high-performance UART (Universal Asynchronous Receiver-Transmitter) with an I²C-bus/SPI interface. This component is designed to offer seamless protocol conversion from I²C-bus/SPI to RS-232/RS-485 and is fully bidirectional. It is particularly suited for hand-held, battery-operated applications due to its low operating and sleeping current and compact packaging options (HVQFN32 and TSSOP28).
