SC16C654IA68,529

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The SC16C654IA68,529 is a quad UART manufactured by NXP USA Inc. in a PLCC68 package. It supports data rates up to 5 Mbits/s at 5 V and 3.3 V, and 3 Mbits/s at 2.5 V. The device features 64-byte transmit and receive FIFOs with selectable interrupt trigger levels. It operates within an industrial temperature range and includes automatic hardware or software flow control. An infrared encoder/decoder interface is integrated for IrDA compliance. The component provides standard modem interface signals and supports both Intel (16-bit) and Motorola (68-bit) bus interfaces.
