UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the manufacturer designation as MaxLinear or Exar, as corporate acquisitions may affect labeling. Confirm the specific suffix 'CJ68' corresponds to the PLCC-64 package variant. Ensure compatibility with existing system voltage requirements of 5.5 V. Check for RoHS compliance status if environmental regulations apply to the target assembly. Validate pinout configurations against current design schematics.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when dual independent UART channels are required within a single IC footprint. The 16-byte FIFOs make it suitable for applications demanding higher throughput than standard 16550-compatible devices. Consider the PLCC-64 package constraints for PCB layout. Verify that the 1.5 Mbps speed meets the specific baud rate requirements of the connected peripherals.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This part belongs to the XR68C192 series of multi-port UART controllers. It serves as a legacy-compatible replacement for older dual UART solutions while offering improved performance through FIFO integration. The device maintains software compatibility with standard UART registers, facilitating easier migration from previous generations of serial interface components.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

Direct substitutes include other dual UART ICs with similar FIFO depths and package types. Verify electrical compatibility regarding supply voltage and signal levels before substitution. Cross-reference pinouts to ensure mechanical fit without redesigning the PCB.
