|---|---|---|---|
This PartLAN8720AI-CP-TR | Standard ordering part number | Microchip LAN8720A 10/100 Ethernet PHY, industrial temp, QFN package, tape & reel | |
LAN8720AI-CP-TR-ABC | Extended ordering/channel part number | Same LAN8720AI device family and package; “-ABC” is typically used as an ordering or supply-chain suffix |
LAN8720AI-CP-TR-ABC is a Microchip LAN8720A 10/100 Ethernet PHY transceiver with MII/RMII interface support, industrial temperature range, QFN package, and tape-and-reel packaging. It is functionally equivalent to LAN8720AI-CP-TR for most sourcing and replacement purposes, subject to final datasheet and ordering-code verification.
Part number breakdown:
- LAN8720A: 10/100 Ethernet PHY transceiver family
- I: Industrial temperature range, typically -40°C to +85°C
- CP: QFN package option
- TR: Tape and reel packaging
- ABC: Ordering/channel suffix, not normally a separate functional specification
Sourcing tip:
If the customer inquiry, supplier label, or invoice shows LAN8720AI-CP-TR-ABC, list the product under the full part number LAN8720AI-CP-TR-ABC and mention LAN8720AI-CP-TR as a related/base ordering code.

LAN8720AI-CP-TR, LAN8720AI-CP-TR-ABC, LAN8720A-CP-ABC, and LAN8720AI-CP-ABC all belong to Microchip’s LAN8720A 10/100 Ethernet PHY transceiver family. The main selection differences are usually the temperature grade, package/order suffix, and packaging format rather than the Ethernet PHY function itself. LAN8720AI versions indicate the industrial-temperature option, making them more suitable for industrial or extended-temperature embedded designs. LAN8720A-CP-ABC may represent the base commercial-grade ordering version, while TR indicates tape-and-reel packaging for automated production. For new designs or replacements, match the full ordering code, temperature range, package type, and packaging requirement before substitution.
Microchip Technology LAN8720AI-CP-TR Microcontrollers Overview
The Microchip LAN8720AI-CP-TR is a compact Ethernet physical-layer transceiver designed for embedded 10/100 Mbps Ethernet connectivity. It supports IEEE 802.3-compliant 10BASE-T and 100BASE-TX operation and is commonly used with microcontrollers, processors, gateways, industrial controllers, and network-enabled embedded products. The device supports RMII operation to reduce pin count and simplify PCB routing, while HP Auto-MDIX helps improve cable connection flexibility. The “AI” version supports industrial temperature operation, making it suitable for more demanding environments. Microchip lists LAN8720A/LAN8720Ai as a small-footprint, low-power 10/100 Ethernet transceiver, and DigiKey lists LAN8720AI-CP-TR as a 100 Mbps full-duplex transceiver with 1.6 V to 3.6 V supply range and -40°C to +85°C operating temperature.
