XR88C192CV-F

Overview

The XR88C192CV-F is a dual-channel Universal Asynchronous Receiver/Transmitter (UART) interface integrated circuit manufactured by MaxLinear, Inc. It operates within a supply voltage range of 2.97 V to 5.5 V and supports data transmission rates up to 230.4 kbps. The device features two independent UART channels, each equipped with a 16-byte transmit and receive FIFO buffer to enhance throughput efficiency. Designed for surface-mount applications, it is housed in a 44-lead LQFP package measuring 10x10 mm. The component includes configurable general-purpose input/output pins, an internal oscillator, and timer/counters, providing flexible integration options for serial communication systems.

Feature Summary

• Dual-channel architecture supporting simultaneous independent serial communication operations
• Integrated 16-byte FIFO buffers on both transmit and receive paths to minimize CPU intervention
• Built-in programmable GPIOs, internal clock oscillators, and hardware timer/counters
• Hardware automatic flow control capability to ensure reliable data integrity

Applications

• Industrial automation controllers requiring robust serial I/O connectivity
• Embedded systems utilizing legacy or standard asynchronous communication protocols
• Telecommunications equipment needing high-reliability data link interfaces

Procurement Notes

Verify the current lifecycle status before design finalization, as this component is marked as discontinued. Confirm that the 44-LQFP footprint matches your PCB layout constraints. Ensure compatibility with the specified 2.97V to 5.5V operating voltage range for your target system power rails. Check for available end-of-life notices or last-time-buy windows from authorized distributors.

Selection Notes

Select this part when a dual UART solution with larger 16-byte FIFOs is required compared to the 8-byte variants like the XR88C92 series. The 44-LQFP package offers a suitable pin count for complex peripheral integration including GPIOs and timers. Consider the maximum data rate of 230.4 kbps against your application's bandwidth requirements. Verify that the CMOS logic levels are compatible with your host microcontroller or processor interface.

Part Context

This component belongs to the XR88Cx92 family of UART interface ICs, which are designed for versatile serial communication needs. It serves as a successor or alternative to older serial controller standards, offering enhanced buffering and integrated peripherals. The device bridges parallel digital systems with asynchronous serial lines, commonly used in environments where multiple serial ports are necessary but space is limited.

Replacement Considerations

Direct pin-compatible replacements may be limited due to the discontinued status. Evaluate the XR88C92 series for similar functionality, noting its smaller 8-byte FIFO capacity. Other dual UART ICs from different manufacturers should be assessed for package compatibility and electrical parameter alignment.
