CYRF69313-40LTXC

RF Transceiver ICS Overview

The CYRF69313-40LTXC is a system-on-chip integrating a 2.4 GHz RF transceiver and an 8051-compatible microcontroller, designed for WirelessUSB™ Low Power applications. It operates within the ISM band above 1 GHz, specifically targeting 2.4 GHz connectivity. The device features a 40-VFQFN package with an exposed pad for thermal management. It supports DSSS and GFSK modulation schemes, enabling robust wireless communication for peripheral devices requiring low power consumption and high integration.

RF Transceiver ICS Feature Summary

• Integrates a 2.4 GHz RF transceiver with an 8051-compatible MCU on a single chip
• Supports WirelessUSB™ Low Power protocol for efficient peripheral connectivity
• Utilizes DSSS and GFSK modulation for reliable data transmission in the ISM band

RF Transceiver ICS Applications

• Wireless USB peripherals such as keyboards and mice
• Low-power industrial sensor nodes
• Consumer electronics requiring short-range wireless control

RF Transceiver ICS Procurement Notes

Verify the specific suffix '40LTXC' against official Infineon/Cypress documentation to confirm package type and temperature range. Ensure compatibility with existing WirelessUSB™ host controllers. Check for obsolescence status as Cypress Semiconductor assets are managed by Infineon Technologies. Confirm lead times and availability through authorized distributors only.

RF Transceiver ICS Selection Notes

Select this component when a combined MCU and RF solution is required for 2.4 GHz applications. It is suitable for designs prioritizing board space reduction and power efficiency over raw processing speed. Consider the 8051 architecture constraints and available development tools for firmware implementation. Evaluate thermal requirements due to the exposed pad design in the VFQFN package.

RF Transceiver ICS Part Context

This part belongs to the CYRF69xxx series of WirelessUSB™ Low Power transceivers. It is manufactured by Cypress Semiconductor Corp, now part of Infineon Technologies. The series is designed to replace wired connections in various consumer and industrial applications, offering a drop-in replacement for standard USB interfaces with wireless capability.

RF Transceiver ICS Replacement Considerations

Check for direct substitutes within the CYRF69xxx family, such as CYRF6936 or CYRF69103, ensuring pinout and feature compatibility. Verify if newer revisions from Infineon offer improved performance or availability. Do not assume cross-compatibility with other 2.4 GHz protocols like Bluetooth or Zigbee without detailed technical comparison.
