Procurement Notes

Verify the specific ordering suffix 'G' against official documentation to confirm RoHS compliance status, as datasheets may vary by revision. Confirm current availability and lifecycle status directly with Zilog or authorized distributors, as this component belongs to the legacy eZ80Acclaim! product line.

Selection Notes

Select this module when a pre-integrated Ethernet and IrDA solution is required to reduce design time. Ensure the host system can accommodate the 3.3V supply voltage and the physical dimensions of 2.5”L x 2.5”W x 0.6”H. Verify that the 20MHz clock speed meets the processing requirements for the intended TCP/IP stack implementation.

Part Context

This module is part of the eZ80Acclaim! product line, which utilizes the optimized pipeline architecture of the eZ80 core. It serves as a rapid development and deployment tool, interfacing with the eZ80 Development Platform for debugging. The module supports ZiLOG’s royalty-free TCP/IP software suite for network configuration and firmware updates.

Replacement Considerations

The eZ80F920020MOD is listed as a related product variant. Other modules in the family include the eZ80F91 Module and the eZ80F93-based development module. Verify pin compatibility and memory specifications before substituting.
