Tomelilla, SwedenBoard maker Invector Embedded Technologies introduces its IP Avenger board. It's a miniature 10/100-MbBit Ethernet module that includes an integrated microcontroller. Price is less than $60 a pop.
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 Silabs (Silicon Laboratories) Type C8051F021/23 device, which, as the part number indicates, is an 8051-derived processor. This block diagram (click to magnify) illustrates some of the on-silicon features of these processors.

The C8051F021 or /23 is really what's responsible for the rich feature set of this product. These controllers are capable of delivering 20-MIPS peak performance with supplied clock options.
An-board JTAG connector eases debug and downloading of code. The IP Avenger's processor works with 64-kbytes of application-programmable flash, and 4-kbytes of SRAM.
Thanks to C8051F021/23s, the mini-module also offers two UARTs. These serial channels let the module adapt to numerous gateway applications. RS-232 or RS-485 gateway applications typically require very few external components.
The module also includes no less than four channels of 10-bit/12-bit A/D conversion. These analog-inputs offer PGAs (programmable gain amplifiers). You also get up to seven channels of 8-bit A/D conversion, also with PGAs. On the output side there are two 12-bit voltage-DAC (digital-to-analog converter) channels.
Other on-module peripherals and I/O include an I2C/SMBus port, an SPI (serial peripheral interface) port, and a 5-channel counter array.
Eval Kit Available
A less-than-$200 evaluation kit contains the tools for starting development. The kit contains one IP Avenger module and a JTAG-serial adapter. An IDE (integrated development environment), with debugger, comes on a supplied CD-ROM. The CD also includes a copy of binaries, as well as a sample application.
