TDA5251XUMA1

Overview

The TDA5251XUMA1 is a radio frequency transceiver integrated circuit manufactured by Infineon Technologies, designed for general ISM band applications operating below 1 GHz. It supports specific frequencies including 315 MHz and operates within the industrial temperature grade. The component utilizes a 38-pin Thin Shrink Small Outline Package (TFSOP) with dimensions of 0.173 inches. This silicon-based device integrates both transmitter and receiver functionalities into a single unit, facilitating wireless communication solutions in compact form factors suitable for various electronic systems requiring reliable RF connectivity.

Feature Summary

• Integrates complete RF transmission and reception capabilities within a single chip architecture
• Supports operation across multiple Industrial, Scientific, and Medical (ISM) frequency bands below 1 GHz
• Utilizes a high-density surface-mount package to minimize printed circuit board footprint

Applications

• Wireless sensor network nodes
• Remote control systems
• Industrial telemetry equipment

Procurement Notes

Verify the exact pinout configuration against the official datasheet before integration, as the 38-pin TFSOP layout requires precise alignment. Confirm that the selected frequency band matches your regulatory requirements for the target market. Ensure thermal management strategies account for the industrial temperature grade specifications during continuous operation. Cross-reference the ordering suffix to guarantee compatibility with existing supply chain components.

Selection Notes

Choose this component when a unified solution for both signal transmission and reception is required to simplify circuit design. Consider the physical constraints of the 38-pin TFSOP package regarding available board space. Evaluate the suitability of the supported ISM bands against local telecommunications regulations. Assess whether the integrated nature of the transceiver meets the power consumption profiles of the intended application compared to discrete alternatives.

Part Context

This transceiver belongs to Infineon's portfolio of wireless communication integrated circuits. It serves as a specialized alternative to separate transmitter and receiver modules, offering reduced component count. The device complements other RF solutions by providing a compact, cost-effective approach for short-range data exchange in consumer and industrial electronics.
