## Article

**INTRODUCTION**

Hs-EVBW5100S /STM32Z is an evaluation board specially launched for the W5100S. Through jumper selection, the interface of 8-bit data parallel bus and SPI bus can be supported without changing the hardware circuit of evaluation board. The CPU adopts the most widely used STM32F103ZET of ST company. The 8-bit data bus interface of STM32F103ZET is used to connect with W5100S to improve the data exchange rate. SPI interface is also supported to simplify the connection of hardware circuits. To facilitate customer testing, hs-nm5100sa module is connected to the evaluation board.

**FEATURES**

Support Hardwired Internet protocols : TCP, UDP, WOL over UDP, ICMP, IGMPv1/v2, IPv4, ARP, PPPoE - Support 4 independent SOCKETs simultaneously - Support SOCKET-less command : ARP-Request, PING-Request - Support Ethernet Power down mode & Main Clock gating for power save - Support Wake on LAN over UDP - Support Serial & Parallel Host Interface : High Speed SPI (MODE 0/3), System Bus with 2 Address signal & 8bit Data - Internal 16Kbytes Memory for TX/ RX Buffers - 10BaseT/100BaseTX Ethernet PHY Integrated - Support Auto Negotiation (Full and half duplex, 10 and 100-based ) - Support Auto-MDIX only when Auto-Negotiation mode - Not support IP Fragmentation - 3.3V operation with 5V I/O signal tolerance
