RF Transceiver ICS Procurement Notes

This component is officially listed as obsolete by the manufacturer. Procurement requires verification of availability through authorized distributors or surplus channels. Buyers must confirm end-of-life status and potential lead times for remaining stock. Alternative sourcing strategies should be evaluated immediately to ensure supply chain continuity for existing designs utilizing this specific part number.

RF Transceiver ICS Selection Notes

Engineers selecting this component must account for its obsolete status in new designs. The device offers integrated transmission and reception capabilities suitable for simple wireless links. Designers should verify compatibility with required ISM frequencies such as 315MHz or 433MHz. The 48-pin VFQFN package necessitates careful thermal management and PCB layout considerations due to the exposed pad requirement for heat dissipation and electrical grounding.

RF Transceiver ICS Part Context

The ATA5823C series belongs to Microchip's portfolio of RF transceivers targeting short-range wireless communication needs. This specific model integrates both transmitter and receiver functions into a single chip, reducing bill-of-materials complexity. It is positioned within the sub-1GHz spectrum, offering regulatory compliance advantages in various global markets compared to higher frequency alternatives. The series emphasizes ease of integration via standard digital interfaces.

RF Transceiver ICS Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete status, direct replacements may require design modifications.
