EZ80L925048MODG

Overview

The EZ80L925048MODG is an Ethernet module based on the eZ80L92 microprocessor, operating at a default clock frequency of 48 MHz. It integrates 1 MB of onboard NOR Flash ROM and 512 KB of zero-wait-state SRAM. The module features a 10 Base-T Ethernet Media Access Controller with an onboard RJ45 connector, an IrDA transceiver, and a GoldCap backup for the Real-Time Clock. It provides 24 general-purpose 5 V-tolerant I/O pins via an I/O connector and supports in-circuit Flash programming. The unit operates on a 3.3 V power supply within a standard temperature range of 0°C to +70°C.
