SC28L198A1A,529

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The SC28L198A1A,529 is an octal UART manufactured by NXP USA Inc., designed for 3.3 V and 5 V supply voltages. It integrates eight full-duplex asynchronous channels, each equipped with 16-byte receiver and transmitter FIFOs to minimize overrun and interrupt overhead. The device supports a synchronous host interface with a 30 ns data bus release time and 125 ns bus cycle time. Baud rates are selectable from 22 fixed options (50–230.4 K baud) or via programmable counters up to 500 K baud. It features automatic address detection, Xon/Xoff flow control, and programmable interrupt priorities. The component is available in an 84-pin PLCC package.
