Chapter 2. Getting Started
Welcome to Eddy! This chapter includes Eddy-CPU overview, main and distinctive features, package
contents for each product, and application fields.
1. Overview
Eddy-CPU is an Embedded Device Server module that comes with a Conexant CX82100-41Z processor,
SDRAM, Flash memory, one 10/100Mbps Ethernet port, 8 bit address/8 bit data bus interface to support
flexible connections to outer devices such as UART, and a maximum of 17 user programmable IOs. Users
can easily implement UART & 232/422/485, I2C interface and much more using example codes and
Evaluation Kit circuits.
Eddy-CPU comes in small form factor (38 x 22mm) but yet has an on board memory and integrated
10/100Mbps network interface which would enable minimized input of time and money for future
application developments.
