SC28L201A1DGG,118

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The SC28L201A1DGG,118 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. It offers programmable baud rates up to 3.125 Mbit/s using a 16× clock or 3 Mbit/s using a 1× clock. The component includes a 16-bit Counter/Timer, an on-chip crystal oscillator, and multifunction I/O ports. It interfaces directly with microprocessors via Intel (80xxx) or Motorola (68000) bus modes.

UARTs (Universal Asynchronous Receiver Transmitter) Feature Summary

• Supports dual-speed channel applications through independent programming of receiver and transmitter operating speeds.
• Integrates intelligent interrupt arbitration that provides context information including current FIFO fill levels.
• Includes hardware flow control capabilities such as RTS/CTS and Xon/Xoff alongside software flow control options.
• Features a three-character recognition system for general purpose, Xon/Xoff, and address wake-up functions.

UARTs (Universal Asynchronous Receiver Transmitter) Applications

• Clustered terminal systems requiring dual-speed communication channels
• Network bridges utilizing independent baud rate generation
• Multi-drop serial communication networks with automatic wake-up capabilities

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the specific ordering suffix matches the required package variant. Confirm the voltage supply requirements align with the target application's power rails. Ensure the bus interface mode selection pin configuration corresponds to the host processor architecture. Check for moisture sensitivity handling requirements during storage and assembly processes.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when a single UART channel with large buffer depths is required. Consider the available bus interface modes compatible with the central processing unit. Evaluate the need for independent baud rate generation versus shared clock sources. Assess the necessity for hardware flow control signals and change-of-state detection features.
