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