TDA5231XUMA1

RF Receivers Overview

The TDA5231XUMA1 is a low-power RF receiver from Infineon's SmartLEWIS family, designed for ASK and FSK modulation protocols. It operates within the 300 MHz to 320 MHz frequency band and supports data rates up to 100 kbps. The device features a superheterodyne architecture with digital baseband processing capabilities. It functions on a supply voltage range of 3 V to 3.6 V and is housed in a 28-pin TSSOP package. The component is rated for an operating temperature range of -40°C to +105°C.

RF Receivers Feature Summary

• Integrates superheterodyne RF front-end with digital baseband processing for simplified system design.
• Supports both Amplitude Shift Keying (ASK) and Frequency Shift Keying (FSK) modulation schemes.
• Optimized for ultra-low power consumption suitable for battery-operated applications.

RF Receivers Applications

• Remote Keyless Entry (RKE) systems
• Tyre Pressure Monitoring Systems (TPMS)
• Home security and alarm systems

RF Receivers Procurement Notes

Verify the specific suffix XUMA1 to confirm tape-and-reel packaging configuration. Ensure compatibility with the target frequency band and modulation requirements. Check current availability status as components may be subject to production lifecycle changes. Confirm moisture sensitivity level handling during assembly processes.

RF Receivers Selection Notes

Select this component for applications requiring robust performance in the 300-320 MHz ISM band. Consider the integrated digital baseband which reduces external component count compared to analog-only receivers. Evaluate the thermal specifications against the maximum ambient temperature of the intended enclosure environment.

RF Receivers Part Context

This part belongs to the TDA52xx series of wireless transceivers by Infineon Technologies. It is specifically engineered for short-range wireless communication needs in consumer electronics and automotive sectors. The series emphasizes ease of integration and high sensitivity for reliable data transmission.

RF Receivers Replacement Considerations

TDA5235XUMA1 offers similar functionality with support for additional frequency bands including 433 MHz, 868 MHz, and 915 MHz. Verify pinout compatibility and software configuration differences before substitution.
