SC28L202A1DGG/G,11

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The SC28L202A1DGG/G,11 is a high-performance dual universal asynchronous receiver/transmitter (DUART) fabricated in an advanced 0.5 micron CMOS process. It features 256-character receive and transmit FIFOs for each channel, supporting 3.3V to 5.0V operation within a -40°C to +85°C temperature range. The device includes pin-programmable interfaces for 68K or 80xxx bus architectures, two independent full-duplex UARTs, and sixteen I/O ports. It supports baud rates from 50 to 2.0 Megabaud, programmable data formats, and an arbitrating interrupt system.

UARTs (Universal Asynchronous Receiver Transmitter) Feature Summary

• Dual independent full-duplex asynchronous receivers and transmitters with large 256-byte FIFOs
• Pin-programmable host interface compatible with both Motorola 68K and Intel 80xxx bus architectures
• Integrated character recognition system supporting general purpose, Xon/Xoff, and address wake-up modes
• Arbitrating interrupt structure with global control registers for efficient multi-channel management

UARTs (Universal Asynchronous Receiver Transmitter) Applications

• High-speed serial communication systems requiring low standby current
• Multi-drop networks utilizing address recognition wake-up capabilities
• Embedded controllers interfacing via standard 68K or 80xxx bus protocols
• Industrial applications operating across extended temperature ranges

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the specific ordering suffix G,11 against the manufacturer's official documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with the required bus interface configuration before integration. Cross-reference the component revision code using the Test and Revision Register to match design requirements.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when dual independent UART channels with substantial buffering are required alongside flexible bus interface options. Consider the 0.5 micron CMOS process benefits for low power consumption if standby current is a critical constraint. Evaluate the need for hardware flow control and character recognition features against simpler single-channel alternatives.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This part belongs to the IMPACT family of integrated circuits designed by Philips Semiconductors, now NXP. It serves as an evolution of previous dual-channel UARTs like the SC26C92, offering enhanced speed, larger FIFOs, and additional I/O capabilities while maintaining functional compatibility with established programming models.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

The SC26C92 is documented as a predecessor with similar power-up configurations but lacks the expanded FIFO sizes and I/O port count. Verify electrical compatibility and register mapping differences when substituting older components.
