PI7C9X754ME

Controllers Overview

The PI7C9X754ME is a quad UART interface integrated circuit manufactured by Diodes Incorporated. It features four independent UART channels, each equipped with a 64-byte FIFO buffer to enhance data throughput and reduce CPU overhead. The device supports standard serial communication protocols including RS-232, RS-422, and RS-485. It is housed in an MQFP-100 surface-mount package suitable for automated assembly. The component operates within industrial temperature ranges and is designed for applications requiring multiple serial ports in compact form factors.

Controllers Feature Summary

• Integrates four independent UART controllers with dedicated 64-byte FIFOs per channel
• Supports standard serial communication protocols including RS-232, RS-422, and RS-485
• Utilizes MQFP-100 surface-mount packaging for space-constrained designs

Controllers Applications

• Industrial automation systems requiring multiple serial connections
• Embedded hardware with limited I/O expansion capabilities
• Telecommunications infrastructure equipment

Controllers Procurement Notes

Verify the specific ordering suffix against official Diodes Incorporated documentation to confirm pinout compatibility and electrical specifications. Confirm RoHS compliance status through current datasheets as manufacturing processes may evolve. Ensure the MQFP-100 footprint matches the target PCB design before procurement.

Controllers Selection Notes

Select this component when four distinct UART interfaces are required within a single package. Evaluate the 64-byte FIFO depth against application latency requirements. Compare the MQFP-100 package dimensions against available board space constraints relative to alternative multi-channel UART solutions.

Controllers Part Context

This part belongs to the Pericom/PI7C9X series of interface ICs acquired by Diodes Incorporated. It serves as a bridge between parallel system buses and serial peripheral devices. The product line focuses on providing high-density serial connectivity for embedded and industrial applications.

Controllers Replacement Considerations

Consult official cross-reference lists for direct replacements. Verify that any substitute maintains the MQFP-100 package and 64-byte FIFO configuration. Ensure voltage levels and protocol support match original design requirements.
