UARTs (Universal Asynchronous Receiver Transmitter) datasheet and documents for XR16V2651IL
UARTs (Universal Asynchronous Receiver Transmitter) Overview
The XR16V2651IL is a dual universal asynchronous receiver/transmitter (DUART) manufactured by Sipex. It integrates two independent UART channels on a single chip, each featuring full hardware flow control and a 14-byte FIFO buffer to enhance data throughput. The device supports baud rates up to 3 Mbps when powered by a 3.3 V supply. It operates within a voltage range of 3.0 V to 3.6 V and includes integrated clock generators capable of generating standard baud rate multiples from an external crystal or oscillator input.
UARTs (Universal Asynchronous Receiver Transmitter) Feature Summary
- Integrates two fully independent UART channels with dedicated transmit and receive sections
- Includes 14-byte transmit and receive FIFO buffers for each channel to reduce CPU overhead
- Supports full hardware flow control via RTS/CTS signals for reliable data transmission
- Features integrated clock generation circuits compatible with external crystals or oscillators
UARTs (Universal Asynchronous Receiver Transmitter) Applications
- Industrial communication systems requiring multiple serial ports
- Embedded controllers needing compact DUART solutions
- Telecommunications equipment utilizing RS-232 or RS-485 interfaces
UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes
Verify the specific suffix against manufacturer documentation to confirm package type and temperature grade. Ensure compatibility with system voltage levels before integration. Cross-reference part numbers with official Sipex or current owner datasheets to validate pinout and electrical specifications.
UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes
Select this component when a design requires two isolated serial interfaces in a small footprint. Compare FIFO depth requirements against other DUART options if higher buffering is needed. Verify that the 3.3 V operating range aligns with the target system power rails and logic levels.
UARTs (Universal Asynchronous Receiver Transmitter) Part Context
This component belongs to the XR16V265x family of dual UARTs. It shares architectural similarities with the XR16C265x series but is optimized for lower voltage operation. The family is designed to replace legacy single UARTs while providing enhanced performance through FIFO technology.
UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations
Check for direct pin-compatible alternatives such as the XR16V2651IV or other variants within the same family. Verify functional equivalence regarding FIFO size and supported baud rates before substitution.
