PI7C9X760BCLEX

Controllers Overview

The PI7C9X760BCLEX is a single-channel full-duplex UART bridge controller manufactured by Diodes Incorporated. It converts I2C-bus or SPI interfaces to RS-232/RS-485/RS-422 protocols. The device features 64-byte transmitter and receiver FIFOs, supports baud rates up to 16Mbit/s with a 4X sampling clock, and operates at supply voltages of 1.8V, 2.5V, or 3.3V. It utilizes a 24-contact TQFN package (ZD) and maintains backward compatibility with the 16C450 register set.

Controllers Feature Summary

• Supports I2C-bus fast speed slave mode or SPI mode 0 slave mode with maximum clock speeds up to 33Mbps.
• Includes programmable hardware flow control using RTS/CTS signals and software flow control with configurable Xon/Xoff characters.
• Features automatic RS-485 slave address detection and driver direction control via the RTS signal.
• Integrates an internal loopback mode, line break generation/detection, and up to eight user-programmable GPIO pins.

Controllers Applications

• Industrial Computing
• Automation and Factory Process Control
• Mobile Computing and Embedded Applications
• Battery Operated Devices

Controllers Procurement Notes

Verify the specific ordering suffix BCLEX against the manufacturer's official documentation to confirm the exact package type and tape-and-reel quantity specifications. Ensure that the selected variant matches the required interface configuration and environmental operating temperature range for the intended deployment.

Controllers Selection Notes

Select this component when a compact UART bridge solution is required for cost-efficient handheld or battery-operated designs. The device is suitable for applications needing protocol conversion between high-speed host interfaces and standard serial peripherals while maintaining low standby current consumption.

Controllers Part Context

This part belongs to the PI7C9X760 family of I2C/SPI to UART bridge controllers. The BCLEX suffix typically denotes a specific packaging configuration, such as tape and reel, distinct from tube-packaged variants like the ZD suffix. All members share the same core functional architecture and register compatibility.

Controllers Replacement Considerations

Direct replacement options within the same product family include other PI7C9X760 variants with different package suffixes. Verify pinout compatibility and electrical specifications before substituting with alternative packages.
