The ZGATE Embedded Security
Development Kit
ZGATE technology incorporates the eZ80F91 MCU and Zilog’s full-featured TCP/IP
stack with a world-class embedded firewall. This highly-configurable firewall protects the
ZTP networking layers from attack by discarding suspicious packets before they reach
ZTP and your embedded application. The ZGATE firewall includes a static packet filter-
ing engine that filters packets according to user-defined configuration rules and a stateful
packet inspection engine that can automatically filter suspicious packets based on unusual
activity. Additionally, select ZGATE products include threshold-filtering mechanisms that
can minimize the affect of packet floods.
Zilog’s ZGATE Embedded Security Development Kit, part number ZGATE000100ZCOG,
provides a general-purpose platform for creating a design based on this eZ80F91 micro-
controller, which has been preprogrammed with a ZGATE security code. The eZ80F91
MCU is a member of Zilog’s eZ80AcclaimPlus! product family, which offers an on-chip
EMAC and Flash memory.
