SC28L201A1DGG,112

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The SC28L201A1DGG,112 is a single-channel Universal Asynchronous Receiver/Transmitter (UART) from the NXP IMPACT family. It supports 3.3 V and 5.0 V operation with an operating temperature range of -40 °C to +85 °C. The device features 256-byte FIFOs for both receiver and transmitter channels. Maximum data transfer rates reach 3 Mbit/s using a 1× clock and 3.125 Mbit/s using a 16× clock. It offers pin-programmable bus interfaces compatible with Intel (80xxx) and Motorola (68000) architectures.

UARTs (Universal Asynchronous Receiver Transmitter) Feature Summary

• Supports dual-speed channel applications through independent programmable baud rate generation for receiver and transmitter channels.
• Integrates intelligent interrupt arbitration that provides context information including current FIFO fill levels and interrupt source identification.
• Includes a three-character recognition system enabling automated Xon/Xoff flow control and multi-drop address wake-up modes.
• Features real-time transmission error checking to verify data integrity by comparing transmitted and received data internally.

UARTs (Universal Asynchronous Receiver Transmitter) Applications

• Clustered terminal systems requiring dual-speed communication capabilities
• Network bridges utilizing independent baud rate settings for different channels
• Multi-drop serial networks employing automatic wake-up and address recognition

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the component matches the specific TSSOP48 package variant designated by the ordering suffix. Confirm the bus interface mode requirements align with the MODE_IM pin configuration options documented in the datasheet. Ensure supply voltage specifications meet the required 3.3 V or 5.0 V operational standards for the target application environment.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this UART when high-performance asynchronous communication with large buffer depths is required. The device is suitable for systems needing flexible bus compatibility with either Intel or Motorola microprocessors. Consider the on-chip crystal oscillator and extensive I/O ports if external timing or modem control circuitry needs to be minimized.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This component belongs to the SC28L201 series within the IMPACT line of data communications parts. It serves as a successor to earlier Philips UARTs, offering extended functionality such as larger FIFOs and faster bus speeds. The device is fabricated using an advanced 0.5 micron CMOS process technology.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

The SC28L202A1 is a dual-channel variant within the same family. Verify if the additional channel and increased I/O port count are necessary for the design. Other members of the IMPACT family may offer similar electrical characteristics but differ in pin counts or specific bus interface implementations.
