Zdots® SBC for eZ80AcclaimPlus!™ Connectivity ASSP

Product Specification

Zdots® SBC for eZ80AcclaimPlus!™

Connectivity ASSP

Zilog’s Zdots® Single Board Computer (SBC) for eZ80AcclaimPlus!™Connectivity

Application Specific Standard Product (ASSP) is a compact, high-performance Ethernet

SBC specially designed for the rapid development and deployment of embedded systems

requiring control and internet/intranet connectivity.

This expandable module is powered by Zilog’s latest power-efficient, high-speed,

optimized pipeline architecture eZ80F91 connectivity ASSP, a member of

eZ80AcclaimPlus! Zilog® family.

eZ80F91 is a high-speed single-cycle instruction-fetch microcontroller, which operates

with a clock speed of 50 MHz. It can also operate in Z80®-compatible addressing mode

(64 KB) or full 24-bit addressing mode (16 MB).

The peripheral-rich Zdots SBC makes it suitable for a variety of applications including

industrial control, IrDA connectivity, communication, security, automation, point-of-sale

terminals, and embedded networking applications.
