XR16L2752IJTR-F

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The XR16L2752IJTR-F is a dual Universal Asynchronous Receiver/Transmitter (UART) interface integrated circuit manufactured by MaxLinear. It features two independent UART channels, each equipped with a 16-byte transmit and receive FIFO buffer to enhance data throughput and reduce CPU overhead. The device supports standard RS-232 communication protocols and operates within a supply voltage range of 2.25 V to 5.5 V. Designed for surface-mount applications, it is housed in a 44-pin PLCC package and functions reliably across an industrial temperature range from -40°C to +85°C.

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

This component is officially designated as End-of-Life (EOL) by the manufacturer. Current availability is restricted to limited stock or surplus markets. Buyers must verify part authenticity and storage conditions carefully due to potential moisture sensitivity issues arising from long-term warehousing. Replacement planning should commence immediately given the discontinuation status.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Engineers selecting this part should prioritize designs requiring dual asynchronous serial links with moderate data rates. The 16-byte FIFO depth is suitable for burst data handling but may require buffering for high-throughput continuous streams. Verify that the system logic levels match the 2.25V to 5.5V operating range and ensure the PCB layout accommodates the 44-pin PLCC footprint constraints.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

The XR16L2752 belongs to the broader XR16L275x family of UART controllers, which are widely used in legacy and industrial embedded systems. This specific model provides a cost-effective solution for adding serial connectivity to microcontroller-based platforms. Its compatibility with standard RS-232 signaling makes it a common choice for interfacing with modems, GPS modules, and other serial peripherals in rugged environments.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

Direct pin-to-pin replacements are not explicitly confirmed in public documentation. Consider evaluating the XR16L2550 series for similar dual-channel functionality or consulting MaxLinear for updated portfolio recommendations.
