SCC2698BE1A84,512

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The SCC2698BE1A84,512 is an enhanced octal universal asynchronous receiver/transmitter (Octal UART) manufactured by NXP USA Inc. It integrates eight full-duplex asynchronous receiver/transmitter channels within a single package. The device supports independent baud rate selection for each channel from 26 fixed rates ranging from 50 to 38.4K baud, non-standard rates up to 115.2K baud, user-defined rates via programmable counter/timers, or external clocks. It features quadruple buffered receiver data registers and operates on a single +5V power supply with low power consumption modes.

UARTs (Universal Asynchronous Receiver Transmitter) Feature Summary

• Eight independent full-duplex asynchronous receiver/transmitter channels
• Quadruple buffered receiver data register to minimize overrun potential
• Programmable data format supporting 5 to 8 data bits plus parity
• On-chip crystal oscillator with TTL compatible logic

UARTs (Universal Asynchronous Receiver Transmitter) Applications

• Clustered terminal systems requiring dual-speed channel applications
• Interrupt-driven serial communication systems
• Multipurpose I/O and modem control interfaces

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm the industrial temperature range (-40 °C to +85 °C) and PLCC package variant. Ensure compatibility with system voltage requirements of +5 V ± 5 % before integration.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when multiple independent serial channels are required in a single footprint. Consider the PLCC package availability and the need for hardware flow control signals available on multipurpose pins. Verify that the system can accommodate the 84-pin configuration and associated address decoding logic.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This part is an enhanced version of the SCC2698A Octal UART. It adds receiver ready/FIFO full status outputs and transmitter empty status outputs accessible via multipurpose I/O pins. The device maintains upward compatibility while providing additional diagnostic and control capabilities through its expanded pinout.
