XR17V352IB113-F

Overview

The XR17V352IB113-F is a dual-channel PCI Express to UART bridge controller manufactured by MaxLinear. It integrates two independent UART interfaces with RS-485/RS-232 capabilities into a single compact package. The device operates within a supply voltage range of 2.97 V to 3.63 V and supports data rates up to 31.25 Mb/s per channel. It features a 256-byte FIFO buffer for each channel to manage data flow efficiently. The component is housed in an 113-pin Fine-pitch Ball Grid Array (FPBGA) package measuring 9x9 mm. It is designed for industrial applications, functioning reliably across a temperature range of -40°C to +85°C.

Feature Summary

• Dual-channel architecture providing independent serial communication paths
• Integrated 256-byte FIFO buffers for enhanced data throughput management
• Supports high-speed data transmission up to 31.25 Mb/s
• Compact 113-pin FPBGA packaging suitable for space-constrained designs

Applications

• Industrial automation systems requiring multiple serial ports
• Telecommunications infrastructure equipment
• Medical devices needing reliable serial connectivity
• Embedded control systems with PCIe host interfaces

Procurement Notes

Verify the specific suffix 'F' indicates the lead-free and RoHS-compliant variant when sourcing. Confirm the 113-pin FPBGA footprint matches the target PCB layout. Ensure the design supports the required 3.3 V power domain and thermal dissipation for the specified operating temperature range. Cross-reference the datasheet revision to confirm pinout compatibility with existing designs.

Selection Notes

Select this component when a dual-port UART solution is required on a PCIe bus. Compare against the XR17V354IB176-F if four channels are needed, noting the larger package size. Consider the XR17V358IB176-F for octal configurations. Verify that the host system provides adequate PCIe lane availability and that the software driver stack supports the MaxLinear UART controller protocol.

Part Context

This part belongs to the XR17V35x series of PCIe UART controllers from MaxLinear. It shares architectural similarities with the XR17V354 and XR17V358 models but offers a reduced channel count. The series is designed to replace legacy parallel or USB-based serial adapters in modern embedded systems. It complements evaluation boards like the XR17V352IB-0A-EVB for development purposes.

Replacement Considerations

Direct functional substitutes include the XR17V354IB113-F if additional channels are acceptable, though pinouts may differ. Check for pin-compatible alternatives from other manufacturers only if the package and electrical specifications align exactly. Verify driver support availability for any cross-brand replacements.
