Overview
The TDA5255XUMA1 is an ASK/FSK RF transceiver from Infineon Technologies, operating in the 433 MHz to 435 MHz ISM band. It functions within a supply voltage range of 2.5 V to 5 V and supports surface-mount installation in a TSSOP-38 package. The component is rated for operation between -40°C and +85°C. This specific variant, identified by the XUMA1 suffix, indicates tape-and-reel packaging. The device integrates transmitter and receiver functionalities for wireless data transmission.
Feature Summary
- Supports both Frequency Shift Keying (FSK) and Amplitude Shift Keying (ASK) modulation schemes for versatile communication protocols.
- Integrates complete radio frequency front-end capabilities into a single compact silicon solution.
- Designed for low-voltage operation to facilitate energy-efficient system designs.
Applications
- Wireless sensor networks requiring short-range data transmission
- Remote control systems for consumer electronics
- Industrial monitoring applications using ISM band frequencies
Procurement Notes
Verify the exact ordering part number against the manufacturer's current documentation, as availability status may vary. Confirm that the TSSOP-38 package and moisture sensitivity classification align with your assembly process requirements. Ensure compatibility with the specified voltage and temperature ranges for your target environment before finalizing procurement decisions.
Selection Notes
Select this component when a combined transmit and receive capability is required for sub-GHz applications. Consider the TSSOP-38 footprint constraints and the need for digital baseband processing integration. Evaluate the power consumption characteristics against system battery life requirements and verify interface compatibility with the host microcontroller.
Part Context
This device belongs to the TDx5255 series of wireless transceivers. It represents a specialized integrated circuit designed for cost-effective and space-constrained wireless applications. The component utilizes standard silicon technology and is intended for general-purpose ISM band communications.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Verify if other members of the TDx5255 family or newer generations from Infineon offer pin-compatible alternatives if discontinuation is a concern.
