TDA5100XUMA1

RF Transmitter Overview

The TDA5100XUMA1 is an RF transmitter integrated circuit manufactured by Infineon Technologies, designed for ASK and FSK modulation protocols. It operates within the 433MHz to 435MHz and 866MHz to 870MHz frequency bands, delivering a maximum output power of 5dBm with a data rate up to 20kbps. The device functions on a supply voltage range of 2.1V to 4V and draws a transmission current of 7mA. It is housed in a 16-TSSOP package (PG-TSSOP-16) suitable for surface mount installation. The component supports PCB antenna integration and operates within a temperature range of -25°C to 85°C.

RF Transmitter Feature Summary

• Supports ASK and FSK modulation schemes for reliable wireless communication
• Integrates directly with PCB antennas for compact surface-mount design
• Operates on low supply voltage ranging from 2.1V to 4V

RF Transmitter Applications

• Alarm systems
• Communication systems

RF Transmitter Procurement Notes

Verify component status as the TDA5100XUMA1 is listed as discontinued or end-of-life in official distributor records. Confirm availability through authorized channels or alternative sources if immediate procurement is required. Check datasheet revisions for any specific handling instructions related to moisture sensitivity level 3. Ensure compatibility with existing board designs before sourcing replacement units.

RF Transmitter Selection Notes

Select this component for applications requiring low-power RF transmission in the 433MHz and 868MHz ISM bands. Consider the 16-TSSOP package constraints for layout space. Evaluate the 5dBm output power against link budget requirements. Verify that the 2.1V to 4V supply range aligns with the system's power architecture. Assess the 20kbps data rate sufficiency for the intended protocol.

RF Transmitter Part Context

The TDA5100XUMA1 belongs to Infineon's TDX series of wireless transceivers, specifically optimized for simple, cost-effective remote control and telemetry applications. It complements receiver counterparts like the TDA7200 series. The part number suffix XUMA1 indicates tape-and-reel packaging. This component represents a silicon-based solution for short-range wireless data transfer in industrial and consumer electronics.

RF Transmitter Replacement Considerations

Public confirmed substitute part numbers are not explicitly documented in the provided source material. The TDA5100INCT and TDA5100INTR are listed as aliases or variants. Due to the discontinued status, direct pin-to-pin replacements should be verified against updated Infineon product portfolios or cross-reference technical specifications carefully.
