Procurement Notes

This component is officially designated as End-of-Life (EOL) by Melexis. Distributors may list remaining stock or surplus inventory, but availability is not guaranteed. Verify the specific revision and lot date against official EOL notifications before procurement. Cross-reference datasheets to ensure compatibility with existing designs, as no new production units are manufactured.

Selection Notes

Select this part only if legacy support for sub-1 GHz FSK/ASK protocols is required. Consider the 115 kb/s data rate limit and 32-pin LQFP footprint during integration. Evaluate alternative active components if long-term supply stability is critical for the product lifecycle.

Part Context

Part of the TH7122 family of low-power RF transceivers. Designed for cost-effective wireless solutions in industrial and consumer markets. Shares architectural similarities with other members in the series while offering specific pinout and packaging options.

Replacement Considerations

No direct public substitute part numbers are confirmed. Check for newer generations in the TH71xx series or comparable sub-1 GHz transceivers from other manufacturers.
