SC16C554DIA68,512

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The SC16C554DIA68,512 is a quad Universal Asynchronous Receiver/Transmitter (QUART) manufactured by NXP USA Inc. It features four independent UART channels with 16-byte transmit and receive FIFOs. The device supports data rates up to 5 Mbit/s at 5 V and 3.3 V, and 3 Mbit/s at 2.5 V. It operates within the industrial temperature range and includes an infrared encoder/decoder. The PLCC68 package allows selection between Intel-style 16-bit and Motorola-style 68-bit bus interfaces via the 16/68 pin.
