EZ80L925148MODG

Overview

The EZ80L925148MODG is an Ethernet module from the eZ80Acclaim! family, manufactured by Zilog. It features a 48 MHz processor and includes 1 MB of Flash memory and 512 KB of SRAM. The module supports IrDA communication. It replaces the older eZ80L925048MODG module while maintaining the same physical form factor. Key hardware differences include an upgrade to an 8 MB external Flash component mapped to CS0 and the removal of the IrDA interface.

Feature Summary

• Replaces eZ80L925048MODG with identical physical dimensions
• Features 8 MB Spansion S29GL064N external Flash on CS0
• Removes IrDA support present in predecessor modules

Applications

• Porting RZK/ZTP applications to updated hardware platforms
• Development using the eZ80Acclaim! Development Platform (99C0858)
• Implementing Zilog File System (ZFS) configurations

Procurement Notes

Verify compatibility with the eZ80Acclaim! Development Platform when integrating this module. Specific jumper settings, such as installing Jumper J20, are required to access the full 8 MB Flash capacity. Ensure project settings use the correct target files for RAM or Flash builds.

Selection Notes

Select this module when upgrading from the eZ80L925048MODG to utilize increased external Flash storage. Developers must update preprocessor definitions to EZ80L925148MODG and remove IrDA code. Verify that the development environment uses compatible ZTGT files for proper memory mapping.

Part Context

This module belongs to the eZ80L92 series of Ethernet modules. It serves as a direct hardware replacement for the eZ80L925048MODG, distinguished primarily by its expanded 8 MB Flash memory and the exclusion of the IrDA peripheral found in earlier versions.

Replacement Considerations

The EZ80L925148MODG replaces the eZ80L925048MODG (99C0857). Hardware changes require modifications to ZTP projects, including updates to CS0 configuration and the removal of IrDA code.
