Overview
The XR16L2550IJ is a dual universal asynchronous receiver/transmitter (DUART) integrated circuit manufactured by Sipex. It features two independent UART channels, each equipped with a 16-byte FIFO buffer to enhance data throughput and reduce CPU overhead. The device supports standard RS-232 communication protocols and operates within a specified voltage range suitable for various industrial applications. Packaged in a 44-pin PLCC format, it integrates necessary control logic for serial data transmission and reception.
Feature Summary
- Dual independent UART channels with dedicated 16-byte FIFO buffers
- Supports standard RS-232 serial communication protocols
- Integrated control logic for efficient data handling
Applications
- Industrial automation systems requiring dual serial ports
- Embedded controllers needing reliable RS-232 connectivity
- Communication gateways utilizing multiple UART interfaces
Procurement Notes
Verify the manufacturer designation as Sipex or its successor entities when sourcing this component. Confirm the package type matches the 44-pin PLCC specification. Ensure the part number suffix aligns with the required temperature grade and operational specifications for your specific design environment.
Selection Notes
Select this component when dual independent serial interfaces are required within a single IC footprint. The 16-byte FIFO depth is suitable for applications demanding moderate data buffering without complex DMA controllers. Verify voltage compatibility with the target system's power supply rails before integration.
Part Context
This component belongs to the XR16L2550 series of dual UART controllers. It is designed to replace older discrete UART solutions by integrating two complete serial ports into one package. The series is commonly used in legacy and modern embedded systems requiring robust serial communication capabilities.
Replacement Considerations
Check for pin-compatible alternatives from manufacturers like MaxLinear or Exar, which have acquired related product lines. Verify electrical parameters such as operating voltage and FIFO depth to ensure functional equivalence.
