XR20M1170IG24-F

Controllers Overview

The XR20M1170IG24-F is a single-channel UART interface integrated circuit manufactured by MaxLinear. It converts I2C or SPI serial data into asynchronous UART signals, featuring a 64-byte transmit and receive FIFO buffer per channel. The device supports data rates up to 16 Mb/s and operates within a supply voltage range of 1.62 V to 3.63 V, compatible with 1.8 V, 2.5 V, and 3.3 V systems. It functions in industrial temperatures from -40°C to +85°C and is housed in a 24-pin TSSOP package.

Controllers Feature Summary

• Provides bidirectional conversion between I2C/SPI master interfaces and standard UART protocols
• Integrates dual 64-byte FIFO buffers to manage data flow and reduce host processor overhead
• Supports high-speed asynchronous communication with baud rates reaching 16 Mb/s
• Operates across wide voltage ranges and industrial temperature extremes for robust connectivity

Controllers Applications

• Industrial automation systems requiring serial port expansion
• Embedded IoT devices needing protocol translation between bus masters and UART peripherals
• Test and measurement equipment utilizing serial communication interfaces
• Automotive infotainment and control modules with limited pin counts

Controllers Procurement Notes

Verify component authenticity through authorized channels due to End-of-Life status. Confirm RoHS compliance details via the official datasheet. Check for Product Change Notices regarding manufacturing updates. Ensure compatibility with existing PCB footprints before procurement. Validate supply chain sources against distributor listings.

Controllers Selection Notes

Select this model when a single UART channel is sufficient for system requirements. Choose the IG24 suffix for TSSOP-24 packaging needs. Consider alternative packages like TSSOP-16 if space constraints differ. Verify voltage levels match the target system's logic standards. Evaluate power consumption specifications against battery-operated design limits.
