SC28L92A1B,528

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The SC28L92A1B,528 is a Dual Universal Asynchronous Receiver/Transmitter (DUART) manufactured by NXP Semiconductors. It operates on a single 3.3 V or 5 V supply and supports an operating temperature range of -40 °C to +85 °C. The device provides two independent full-duplex asynchronous channels, each equipped with 16-byte receive and transmit FIFOs. It features pin-programmable bus interfaces for either Intel (80xxx) or Motorola (68xxx) architectures. Data rates are selectable from 28 fixed baud rates up to 230.4 kBd, or higher speeds using external clocks.

UARTs (Universal Asynchronous Receiver Transmitter) Feature Summary

Dual full-duplex asynchronous receiver/transmitter channels
Pin-programmable interface for Intel or Motorola bus architectures
16-character FIFOs for both receiver and transmitter paths
Integrated crystal oscillator and programmable baud rate generator

UARTs (Universal Asynchronous Receiver Transmitter) Applications

Clustered terminal systems requiring dual-speed channel operation
