XR20M1170IG16

Controllers Overview

The XR20M1170IG16 is a single-channel UART interface integrated circuit manufactured by MaxLinear. It converts I2C or SPI serial data into asynchronous UART signals, supporting data rates up to 16 Mb/s. The device features a 64-byte transmit and receive FIFO buffer to enhance throughput efficiency. It 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. Power consumption is low, with operating currents specified at 250 uA and 500 uA depending on conditions. The component functions reliably across an industrial temperature range from -40°C to +85°C and is housed in a TSSOP-16 surface-mount package.

Controllers Feature Summary

• Supports high-speed asynchronous serial communication with data rates reaching 16 Mb/s
• Integrates 64-byte dual FIFO buffers for efficient data handling and reduced CPU overhead
• Provides flexible system integration through I2C and SPI control interfaces
• Operates efficiently with low power consumption suitable for battery-powered applications

Controllers Applications

• Industrial automation systems requiring serial connectivity
• Embedded IoT devices needing protocol conversion
• Consumer electronics with limited pin count constraints
• Telecommunications equipment utilizing serial management interfaces

Controllers Procurement Notes

Verify the specific suffix of the part number, as the XR20M1170IG16 may be listed under variations such as XR20M1170IG16TR-F. Confirm the lifecycle status, as some variants are marked as Not Recommended for New Designs (NRND). Ensure compatibility with existing PCB footprints and verify that the required packaging format matches available inventory sources.

Controllers Selection Notes

Select this component when a single UART port is sufficient for the design requirements. The choice depends on the need for I2C/SPI to UART translation rather than native parallel interfaces. Consider the TSSOP-16 package size relative to board space constraints. Evaluate the 16 Mb/s speed limit against application baud rate needs. Verify that the 1.62 V to 3.63 V input range aligns with the system's power rails.

Controllers Part Context

This part belongs to the XR20M1170 series of I2C/SPI to UART controllers. It serves as a compact solution for adding serial communication capabilities to systems controlled by microcontrollers or processors lacking dedicated UART hardware. The series is designed to replace traditional level shifters and interface chips in space-constrained designs.

Controllers Replacement Considerations

Check for direct substitutes within the XR20M1170 family, such as the XR20M1170IL28-F or XR20M1170IG24TR-F, noting differences in package type and lifecycle status. Verify pin-to-pin compatibility before substitution. Review Product Change Notices (PCN) for any manufacturing updates affecting equivalent parts.
