Mini 100 Mbit Ethernet integrates microcontroller

It is a miniature 10/100-MbBit Ethernet module that includes an integrated microcontroller. The price is less than $60. With its minimal dimensions of 1.38 in. x 2.16 in. (34.5 mm x 54 mm), the communications module can be used for compact designs such as surveillance systems or vibration analysis equipment. The module includes a 3.3-V regulator and 5-V-tolerant I/Os. The embedded microcontroller is a Silicon Laboratories (Silabs) Type C8051F021/23 device, which is an 8051-derived processor. The C8051F021 or /23 is responsible for the rich feature set of this product, delivering 20 MIPS peak performance with supplied clock options. An on-board JTAG connector eases debugging and downloading of code. The processor works with 64 kbytes of application-programmable flash and 4 kbytes of SRAM. The mini-module also offers two UARTs, allowing adaptation to various gateway applications. RS-232 or RS-485 gateway applications typically require very few external components. The module includes four channels of 10-bit/12-bit A/D conversion with programmable gain amplifiers (PGAs) and up to seven channels of 8-bit A/D conversion, also with PGAs. On the output side, there are two 12-bit digital-to-analog converter (DAC) channels. An evaluation kit, priced under $200, contains the tools necessary for development, including one IP Avenger module and a JTAG-serial adapter. An integrated development environment (IDE) with a debugger is provided on a supplied CD-ROM, which also includes binaries and a sample application.
