EZ80F915005MODG

Overview

The Zilog EZ80F915005MODG is an eZ80F91 Mini Enet Module designed for embedded systems requiring Ethernet connectivity. It features a 50 MHz eZ80F91 microcontroller with 256 KB on-chip Flash and 8 KB SRAM, supplemented by 128 KB external SRAM. The module integrates a Micrel KS8721BL 10/100 Base-T Ethernet PHY with an RJ45 connector. It provides 32 general-purpose I/O pins via two 56-pin mini-headers (J1 and J2) for peripheral expansion. Operating at 3.3 V with a standard temperature range of 0°C to +70°C, the module measures 50.8 mm x 48.3 mm.
