Overview

nnnn

Zilog introduces ZGATE™ Embedded Security, which combines multiple world-class technologies for safer, faster

nnnn

and better deployment of your embedded communication applications. lncorporatingtheeZ80F91 MCU and

nnnn

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

nnnn

tools to design, build and bringyour communication product to market.

nnnn

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

nnnn

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

nnnn

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

nnnn

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

nnnn

Internet applications.

nnnn

nnnn

• Lockdown mode

nnnn

• API for event logging

nnnn

ZGATE11 Firewall Features

nnnn

■ Ethernet, IP/UDP/TCP/ICMP filtering

nnnn

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

nnnn

• API for event logging

nnnn

■ Easily-configurable filtering rules:

nnnn

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

nnnn

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

nnnn

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