XR68C192IJTR-F

Overview

The XR68C192IJTR-F is a dual-channel Universal Asynchronous Receiver and Transmitter (UART) integrated circuit manufactured by MaxLinear, Inc. It operates within a supply voltage range of 2.97 V to 5.5 V, supporting standard logic levels of 2.5 V, 3.3 V, and 5 V. The device features an internal oscillator and provides 8 bytes of transmit and receive FIFO memory per channel. It supports data rates up to 1 Mb/s and functions reliably across an industrial temperature range from -40°C to +85°C. The component is housed in a 44-pin PLCC package with J-leads, designed for surface-mount installation.

Feature Summary

• Dual independent UART channels with dedicated 8-byte FIFO buffers for each transmitter and receiver path.
• Integrated internal oscillator eliminates the need for external clock components.
• Compatible with multiple supply voltages including 2.5 V, 3.3 V, and 5 V systems.

Applications

• Industrial communication gateways requiring robust serial I/O
• Embedded control systems utilizing RS-232 or RS-485 interfaces
• Data acquisition modules needing high-speed asynchronous serial links

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to end-of-life status. Request original datasheets and lot traceability documentation to ensure compliance with RoHS standards. Confirm package integrity upon receipt, as moisture sensitivity may affect solderability if storage conditions were not maintained according to JEDEC guidelines.

Selection Notes

Select this part when dual-channel asynchronous communication is required in space-constrained designs. The 44-PLCC package offers a compact footprint suitable for dense PCB layouts. Ensure system power rails align with the supported 2.5 V, 3.3 V, or 5 V operating ranges. Consider the 1 Mb/s maximum data rate against application throughput requirements before finalizing the design.

Part Context
