Specifications

Stresses greater than those listed in Table 6 can cause permanent damage to the device. These ratings are stress ratings only. Operation of the device at any condition outside those indicated in the operational sections of these specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. For improved reliability, unused inputs should be tied to one of the supply voltages (V_DD or V_SS).

Description

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 microprocessor, which can operate with a clock speed of 50MHz. It can operate in Z80- compatible addressing mod e (64KB) or full 24-bit addressing mod e (16MB).

The rich peripheral set of the eZ80190 makes it suitable for a variety of applications, including industrial control, communication, security, automation, point-ofsale terminals, and embedded networking applications.
