Zilog’s ZGATE

Overview

Zilog introduces ZGATE

and better deployment of your embedded communication applications. Incorporating the eZ80F91 MCU and

Zilog’s full-featured TCP/IP stack with a world-class embedded firewall produces technology that provides the

tools to design, build and bring your communication product to market.

The eZ80F91 MCU is the industry’s first MCU featuring a high-performance 8-bit microcontroller with an

integrated 10/100 BaseT EMAC. It is a power-efficient, optimized pipeline architecture microcontroller with a

maximum operating speed of 50 MHz. Offering on-chip Flash Memory, SRAM, Ethernet MAC, and rich

peripherals, the eZ80F91 is well-suited for industrial, communication, automation, security, and embedded

Internet applications.

ZGATE

Ethernet, IP/UDP/TCP/ICMP filtering

Extremely low latency; tests show improved network throughput under load by blocking packets earlier

API for event logging

Easily-configurable filtering rules:

™

Firewall Features

Static filtering

Stateful packet inspection

Port, protocol and address limits

Threshold-based filtering

*The ZGATE Embedded Security Development Kit (ZGATE000100ZCOG) ships with the Premium firewall package.

Firewall Features

Static/rules-based filtering blocks packets based on configurable rules

Dynamic filtering/stateful packet inspection (SPI) blocks packets based on connection state

Choose your firewall package based on application requirements – see table below
