RF Transceiver ICS Procurement Notes

This component is classified as obsolete or discontinued by the manufacturer. Availability is limited to existing stock from third-party distributors. Verify authenticity and lot dates carefully when sourcing from secondary markets. Ensure compatibility with current supply chain strategies due to end-of-life status.

RF Transceiver ICS Selection Notes

Select this part only if legacy system compatibility requires specific Microchip RF architecture. Consider alternative active components for new designs due to discontinuation. Evaluate power consumption requirements against the specified receive current range. Confirm frequency band alignment with regional regulatory standards before integration.

RF Transceiver ICS Part Context

The ATA5428 series represents a family of low-power RF transceivers designed for ISM band applications. This specific variant utilizes a VQFN package suitable for space-constrained PCB layouts. It belongs to the broader category of wireless connectivity solutions provided by Microchip Technology for industrial and consumer electronics.

RF Transceiver ICS Replacement Considerations

No direct public substitute part numbers are confirmed in available documentation. Designers should evaluate newer generations of RF transceivers from Microchip or other manufacturers offering similar ISM band support and modulation capabilities.
