UARTs (Universal Asynchronous Receiver Transmitter) Overview

The SC28L198A1BE,557 is an octal UART providing eight full-duplex asynchronous channels. It features sixteen-byte receiver and transmitter FIFOs per channel to minimize overrun and interrupt overhead. The device supports a single 3.3V or 5V supply and utilizes a synchronous host interface with a 30 ns data bus release time. Baud rates range from 50 to 460.8K baud using internal generators or external clocks. It includes programmable Xon/Xoff flow control, automatic address detection, and vectored interrupts.

UARTs (Universal Asynchronous Receiver Transmitter) Feature Summary

Eight independent full-duplex UART channels with integrated 16-byte FIFOs for both reception and transmission.
Synchronous host interface supporting burst mode access with fast data bus release times.
Programmable in-band flow control using user-defined Xon/Xoff characters and hardware handshaking.
Automatic address recognition in multi-drop mode and three-byte general purpose character recognition.

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and temperature range. Confirm that the component meets all applicable industrial standards required for the target environment. Cross-reference the part number with official distributor catalogs to ensure compatibility with existing inventory management systems.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when multiple serial interfaces are required within a single footprint. Ensure the host system clock frequency exceeds twice the maximum input clock frequency. Verify that the power supply voltage matches the specific variant requirements for TTL or CMOS interface levels.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This device belongs to the Philips/NXP Octal UART family, designed for high-density serial communication applications. It replaces older parallel expansion methods by integrating eight channels into a single CMOS-LSI chip. The architecture supports complex interrupt arbitration and flexible baud rate generation for diverse communication protocols.
