MMnet104
Updated: Aug 9, 2012
Description
The MMnet104 is the lowest priced Embedded Ethernet minimodule with AVR. The heart of the module is the RISC Atmega128 microcontroller with 128kB of program memory and 128kB of (external) RAM memory, co-operating with the Ethernet RTL8018AS controller (100BaseTX). The memory controller built around a programmable CPLD device manages the address space of the microcontroller, generates address strobe/selection signals used during extension of the server by external I/O units, and serves the banking of RAM memory. The minimodule has an 8 MB DataFlash serial memory for storage of WWW pages and of any files e.g. with measurement data. The memory is connected to a fast SPI bus with 8 Mb/s transmission speed. The MMnet104 has been equipped with a RTC clock built around the DS1307 device, connected to the I2C bus. Together with the RTC circuit goes a socket for a lithium battery providing many guaranteed years of uninterrupted clock operation. The MMnet104 is delivered loaded with the WWW Server application and WWW demonstration pages with examples of using CGI and Flash.
