nnnnOverview
nnnnZilog introduces ZGATE™ Embedded Security, which combines multiple world-class technologies for safer, faster
nnnnand better deployment of your embedded communication applications. lncorporatingtheeZ80F91 MCU and
nnnnZilog's full-featured TCP/IP stack with a world-class embedded firewall produces technology that provides the
nnnntools to design, build and bringyour communication product to market.
nnnnThe eZ80F91 MCU is the industry's first MCU featuring a high-performance 8-bit microcontroller with an
nnnnintegrated 10/100 BaseT EMAC. It is a power-efficient, optimized pipeline architecture microcontroller with a
nnnnmaximum operating speed of 50 MHz. Offering on-chip Flash Memory, SRAM, Ethernet MAC, and rich
nnnnperipherals, the eZ80F91 is well-suited for industrial, communication, automation, security, and embedded
nnnnInternet applications.

nnnnZGATE11 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:
nnnnStatic/rules-based filtering blocks packets based on configurable rules
nnnnDynamic filtering/stateful packet inspection (SPI) blocks packets based on connection state
nnnnChoose your firewall package based on application requirements - see table below
