SC28L202A1DGG,118

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The SC28L202A1DGG,118 is a dual universal asynchronous receiver/transmitter (DUART) fabricated in an advanced 0.5 micron CMOS process. It features two independent full-duplex channels, each equipped with 256-character receive and transmit FIFOs. The device supports 3.3V to 5.0V operation and includes pin-programmable interfaces for 68K or 80xxx bus architectures. It provides 16 total I/O ports, an arbitrating interrupt system, and programmable baud rates selectable from 27 fixed rates ranging from 50 to 2.0 Megabaud.

UARTs (Universal Asynchronous Receiver Transmitter) Feature Summary

• Dual independent asynchronous receiver/transmitters with 256-character FIFOs per channel
• Pin-programmable interface supporting both 68K and 80xxx bus architectures
• Integrated arbitrating interrupt system for efficient host management
• Three-character recognition system enabling general purpose, Xon/Xoff, and address wake-up modes

UARTs (Universal Asynchronous Receiver Transmitter) Applications

• High-performance serial communication systems requiring low standby current
• Multi-drop networks utilizing address recognition wake-up capabilities
• Embedded controllers interfacing via 68K or 80xxx bus architectures

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the ordering suffix '118' against official NXP documentation to confirm specific tape-and-reel packaging specifications. Ensure the component matches the required voltage range of 3.3V to 5.0V and the specified temperature operating conditions before integration into the design.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this DUART when high throughput is required due to its large 256-byte FIFOs. Choose between the 68K or 80xxx bus interface based on the target processor architecture. Consider the device if low power consumption is critical, as it offers standby currents below 10 microamperes.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This component belongs to the IMPACT family of serial communication controllers. It extends the functionality of previous Philips dual-channel UARTs by offering faster bus speeds, larger buffers, and enhanced configuration options while maintaining compatibility with established programming models.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

The SC28L202 serves as a functional successor to earlier Philips dual-channel UARTs. Verify compatibility with legacy designs referencing similar architectures, ensuring that differences in FIFO depth and bus interface pinouts are accounted for during migration.
