概要
Description
- IEEE 802.3u compliance (Fast Ethernet)
- Auto-negotiation for speed/duplex detection
- Low power consumption with power-down modes
- Built-in LDO regulator (3.3V operation)
- HP Auto-MDIX for automatic cable polarity correction
The DM9161BEP is commonly used in embedded systems, industrial applications, and networking devices requiring reliable Ethernet connectivity. It interfaces with microcontrollers or processors via MII/RMII and supports LED indicators for link/activity status.
Package: 48-pin LQFP
Operating voltage: 3.3V
For detailed specifications, refer to the datasheet.
Features
- MII/RMII Interface: Supports both MII (Media Independent Interface) and RMII (Reduced MII) for flexible MAC connectivity.
- Auto-Negotiation: Automatically selects optimal speed (10/100 Mbps) and duplex mode (half/full).
- Low Power: Operates at 3.3V with power-saving modes.
- HP Auto-MDIX: Eliminates need for crossover cables by auto-detecting TX/RX pairs.
- LED Indicators: Provides link, activity, and speed status outputs.
- IEEE 802.3u Compliance: Fully compatible with Fast Ethernet standards.
- Industrial Temp Range: Supports -40°C to +85°C for harsh environments.
- Small Footprint: Available in 48-pin LQFP package.
Ideal for embedded networking in IoT, industrial, and consumer applications.
