Overview

Description

KSZ8041RNL is a 10/100 Mbps Ethernet PHY transceiver from Microchip (Micrel). It provides the physical layer between a MAC and the network (RJ-45) and is designed for embedded systems.
Key points:
- Interfaces: connects to a MAC via RMII (or MII) and to Ethernet magnetics/RJ-45.
- IEEE 802.3: supports 10/100BASE-TX, auto-negotiation, and auto-MDIX.
- Management: uses MDIO/MDC for register access and status.
- I/O and power: typically single-supply operation (commonly around 3.3V) with LED outputs for link/activity and low-power modes.
- External components: requires transformer/magnetics and proper termination as per the datasheet.
Common use: microcontroller or SoC with an RMII/MII MAC connects to a network via KSZ8041RNL.
For exact pinout, electrical specs, and register map, consult the KSZ8041RNL datasheet/product page.

Features

KSZ8041RNL Features (concise):
- 10/100BASE-TX Ethernet PHY with Auto-Negotiation
- Speed/duplex: supports 10 Mbps or 100 Mbps; full- or half-duplex
- MAC interface: flexible MII or RMII selectable
- Auto-MDI/MDIX (automatic crossover)
- Integrated status LEDs for Link and Activity
- External clock: requires a 25 MHz reference clock
- Small footprint, RoHS-compliant package
- Low-power modes and power-down option
- ESD/EMI robust design on PHY pins
Note: Always verify exact pinout and interface options in the latest datasheet for your package variant.

Package

KSZ8041RNL is in a 28-pin narrow-lead SSOP (SSOP-28) package.

Pinout

- Pin count: 28 pins (28‑pin QFN, RNL package)
- Function: 10/100BASE-T Ethernet PHY (physical layer transceiver) with RMII/MII interface to the MAC and MDI side to the magnetics/RJ45. Includes management interface (MDIO/MDC) and control/status pins (e.g., reset, interrupt, LED outputs).

Manufacturer

The KSZ8041RNL is manufactured by Microchip Technology Inc. (originally Micrel Semiconductor). Microchip is a global semiconductor company that designs and manufactures integrated circuits, including microcontrollers, analog/mixed-signal ICs, memory, and connectivity devices like Ethernet PHYs.
