TDA5240XUMA1

RF Receivers Overview

The TDA5240XUMA1 is a SmartLEWIS™ RF receiver supporting ASK and FSK modulation. It operates in the 300-320 MHz, 425-450 MHz, 863-870 MHz, and 902-928 MHz bands. The device features a superheterodyne architecture with integrated RSSI. Supply voltage ranges from 3V to 3.6V or 4.5V to 5.5V. Sensitivity reaches -118dBm with a maximum data rate of 112kcps. It uses a 28-TSSOP package and functions between -40°C and 105°C.

RF Receivers Feature Summary

• Multi-channel configuration capability for flexible frequency band selection
• Integrated RSSI for signal strength monitoring
• Superheterodyne architecture providing high blocking performance
• Digital baseband interface reducing host microcontroller load

RF Receivers Applications

• Remote Keyless Entry (RKE) systems
• Telemetry applications
• Security technology implementations

RF Receivers Procurement Notes

Verify component authenticity through official Infineon channels or authorized distributors. Confirm RoHS compliance status and check for specific manufacturing date codes relevant to project timelines. Ensure storage conditions respect moisture sensitivity level 3 requirements before reflow soldering processes.

RF Receivers Selection Notes

Select this component when multi-channel operation across sub-1 GHz ISM bands is required. The integrated digital baseband simplifies system design compared to single-channel alternatives. Verify that the 28-TSSOP package fits the PCB layout constraints and that the operating temperature range meets environmental specifications.

RF Receivers Part Context

Part of the SmartLEWIS RX+ family designed for low-power wireless control. It offers higher integration than predecessors like the TDA5211, combining LNA, IF filter, and demodulation. The TDA5240 specifically enables quad-configurable channel reception, distinguishing it from single-channel variants within the same series.

RF Receivers Replacement Considerations

TDA5235XUMA1 serves as a single-channel alternative within the same family. TDA5225XUMA1 provides multi-channel support without a digital baseband interface. Direct substitution requires verifying channel configuration needs and interface compatibility.
