XR16C2852CJTR-F

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The XR16C2852CJTR-F is a dual universal asynchronous receiver and transmitter (UART) manufactured by MaxLinear. It operates within a voltage range of 2.97 V to 5.5 V and supports data rates up to 3 Mbps at 5 V and 2 Mbps at 3.3 V. The device features 128-byte transmit and receive FIFOs with programmable trigger levels and level counters. It includes automatic hardware flow control, software flow control, and IrDA 1.0 encoder/decoder capabilities. The component is housed in a PLCC-44 package.

UARTs (Universal Asynchronous Receiver Transmitter) Feature Summary

UARTs (Universal Asynchronous Receiver Transmitter) Applications

• Telecommunication network routers
• Ethernet network routers
• Cellular data devices
• Factory automation and process controls

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the specific manufacturer source for this part number, as distribution records often list it under Exar Corporation or MaxLinear depending on the acquisition timeline. Confirm the presence of the 'F' date code suffix if 5V tolerant inputs are required, as this feature applies to devices marked with 'F2 YYWW' or newer. Ensure the PLCC-44 package availability matches the TR-F reel designation.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when a dual-channel UART solution with deep 128-byte FIFOs is necessary to reduce CPU interrupt load. It serves as a direct replacement for the ST16C2552 and XR16L2752 in existing designs requiring pin compatibility. Consider the 5V tolerance feature if the system interface voltages vary between 3.3 V and 5 V logic levels without additional level shifting.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This device belongs to the enhanced 16C550-compatible UART family, offering improved performance over standard 16C550 controllers. It integrates advanced features such as automatic RS-485 direction control and selectable auto RTS hysteresis. The series supports both crystal oscillator and external clock inputs, providing flexibility for various timing requirements in embedded systems.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

The XR16C2852CJTR-F is functionally compatible with the ST16C2552 and XR16L2752. Verify that the substitute part includes the 'F' date code if 5V tolerant inputs are specified in the design requirements.
