Silicon Labs’ Si3400 power over Ethernet (PoE) powered device controller (PD) converts
the high-voltage signal from a 10/100/1000BASE-T PoE connection into a regulated,
low-voltage output supply. With integrated diode bridges and transient surge suppressor,
the Si3400 enables direct connection of the IC to the Ethernet RJ-45 connector.
The CP220x single-chip embedded Ethernet controller contains an integrated IEEE 802.3
Ethernet media access controller (MAC), a 10BASE-T physical layer (PHY), and 8 kB of
non-volatile Flash memory. The CP220x adds Ethernet connectivity to any MCU or host
processor with 11 or more port I/O pins.

Designing Embedded Ethernet Systems Has Never Been EasierThe Si3400 PD controller is a complete power management solution for PD applications that supports both IEEE 802.3af compliant and pre-
standard products, while the CP220x Ethernet controller makes it easy to add Ethernet functionality to any design. Combined with Silcon Labs’
high-performance, mixed-signal MCUs, the low-cost Si844x digital isolators, and a full suite of evaluation kits development tools and
reference designs, designing embedded Ethernet systems has never been easier.
Ethernet Development KitThe Ethernet Development Kit provides all the necessary hardware and software to develop
real-world embedded systems using the CP2200, C8051F MCU and industry-proven CMX
Micronet™ protocol stack. Included in the kit is a CP2200 Ethernet development board,
100 MHz C8051F120 MCU target board, integrated development environment, a TCP/IP
configuration wizard that generates TCP/IP libraries, a USB debug adapter and all
necessary cables to debug the MCU and connect it to an Ethernet network.
