High-Performance Connectivity ASSP
Overview
The eZ80AcclaimPlus! Connectivity ASSP is the latest in the award-winning eZ80Acclaim!® product family,
which integrates a high-performance Flash ASSP core with a fast 10/100 BaseT EMAC. Our power-efficient,
optimized pipeline architecture features a high performance core that operates up to a speed of 50 MHz, and
offers on-chip Flash Memory, SRAM, an Ethernet MAC (EMAC), and rich peripherals. Adding to the existing
eZ80Acclaim! feature set, the eZ80AcclaimPlus! touts an updated embedded internet software suite (ZTP),
a flexible line of single-board computers (SBCs) named Zdots®, and an additional 10% system performance
boost that equates to faster program execution and smaller memory space requirements over the current
eZ80Acclaim! family.
The eZ80AcclaimPlus! Connectivity ASSP is a great time-to-market embedded solution for any device that
needs Ethernet connectivity and is well-suited for industrial, communication, automation, security, consumer
electronics, medical, entertainment, vending machines, and other embedded Internet applications.
