The eZ80190 Module
The eZ80190 Module is a compact, high-performance Ethernet module specially
designed for the rapid development and deployment of embedded systems
requiring control and Internet/Intranet connectivity. It features the low-cost
eZ80190 microprocessor powered by ZiLOG’s latest power-efficient, high-speed
eZ80^® CPU.
The eZ80190 microprocessor is a high-speed single-cycle instruction-fetch micro-
processor, which can operate with a clock speed of 50 MHz. It can operate in Z80-
compatible addressing mode (64 KB) or full 24-bit addressing mode (16 MB).
The rich peripheral set of the eZ80190 makes it suitable for a variety of applica-
tions, including industrial control, communication, security, automation, point-of-
sale terminals, and embedded networking applications.
