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.

1

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
(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.
