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 baud rates from 50 to 2.0 Megabaud. The device operates within a supply voltage range of 3.3 to 5.0 volts and supports an operating temperature range of -40°C to +85°C. It includes pin-programmable interfaces for 68K or 80xxx bus architectures, 16 total I/O ports, and an arbitrating interrupt system.

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the ordering suffix G:11 against the manufacturer's current documentation to confirm specific package type and tape-and-reel specifications. Ensure the component meets the required industrial temperature grade and voltage compatibility before integration into the final design.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when dual independent UART channels with substantial buffering are required. It is suitable for applications demanding flexible bus interface options and advanced flow control mechanisms. Consider the available I/O ports if additional general-purpose signaling is needed alongside serial communication.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This part belongs to the IMPACT family of integrated circuits, designed for compatibility with 3.3V to 5.0V logic levels. It extends the functionality of previous Philips dual-channel UARTs by offering faster bus speeds, larger FIFOs, and enhanced power management capabilities through low standby current consumption.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

The SC26C92 serves as a functional predecessor with similar power-up configuration but lacks the extended FIFO depth and speed improvements. Verify register compatibility and timing requirements when migrating from older dual UART designs to ensure seamless software integration.
