LAN8720A-CP-TR is a Microchip Technology 10BASE-T/100BASE-TX Ethernet PHY transceiver in 24-pin QFN, tape and reel — for embedded network connectivity: printers, set-top boxes and industrial controllers adding 10/100 Ethernet via RMII. Single 3.3 V supply, HP Auto-MDIX and auto-negotiation is the selection point: a small-footprint PHY that just works with any RMII MAC. Selection advice: the TR suffix denotes tape and reel; the A-CP grade covers the 0 °C to +85 °C commercial range — for the −40 °C to +85 °C industrial range, the LAN8720AI variants are the siblings. Lifecycle note: this ordering code is flagged Not Recommended for New Designs — for new designs, ask about the current-generation Microchip PHY as the forward path in your RFQ, and confirm date code and traceability for legacy builds. Parameters verified against distributor and manufacturer documentation.
