UARTs (Universal Asynchronous Receiver Transmitter) datasheet and documents for XR16L2552IJ
UARTs (Universal Asynchronous Receiver Transmitter) Overview
The XR16L2552IJ is a dual universal asynchronous receiver and transmitter (UART) manufactured by Sipex. It features two independent UART channels, each equipped with 16-byte transmit and receive FIFOs to support block mode data transfers. The device operates within a voltage range of 2.25V to 5.5V and includes 5-volt tolerant inputs. It supports baud rates up to 3.125Mbps via independent programmable generators and offers hardware and software flow control.
UARTs (Universal Asynchronous Receiver Transmitter) Feature Summary
- Dual independent UART channels with 16-byte FIFOs for enhanced throughput
- Supports 5-volt tolerant inputs for flexible system interfacing
- Includes automatic hardware and software flow control mechanisms
- Provides onboard diagnostics through internal loop-back capability
UARTs (Universal Asynchronous Receiver Transmitter) Applications
- Industrial communication systems requiring serial data transmission
- Embedded controllers needing multiple serial interfaces in compact packages
- Telecommunications equipment utilizing RS-232 or similar protocols
UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes
Verify the manufacturer designation carefully, as Exar Corporation was acquired by MaxLinear. Confirm that the specific part number corresponds to the original Exar specifications rather than potential variations introduced during corporate transitions. Ensure the package type matches the required PCB layout constraints before ordering.
UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes
Select this component when a design requires two independent serial ports with moderate data buffering capabilities. It serves as a direct pin-to-pin replacement for National Semiconductor PC16552 devices. Consider the operating voltage range and input tolerance levels to ensure compatibility with the target system logic levels.
UARTs (Universal Asynchronous Receiver Transmitter) Part Context
This device belongs to the L2552 series of dual UARTs designed for low-power applications. It improves upon previous generations by supporting lower operating voltages while maintaining compatibility with standard 5-volt tolerant interfaces. The series is widely used in portable and battery-operated electronic devices.
UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations
The XR16L2552IJ is functionally compatible with the ST16C2552 and XR16L2752. It also serves as a drop-in replacement for the National Semiconductor PC16552 in 44-PLCC packages. Verify pinout consistency when substituting these parts.
