The reference design kit includes a PoE-VOICE-EB reference design board which contains an IEEE 802.3af compliant Power over Ethernet (PoE) circuit, 8 kHz voice/speech sampling system and an IEEE 802.3 embedded Ethernet connection. The reference design board provides a hardware platform for evaluating and developing software for embedded systems that use the C8051F340 as the main controller, the CP2201 as the Ethernet controller and the Si3402 as the PoE controller.
The reference design software uses the TCP/IP Configuration Wizard, which generates starter firmware based on the industry standard CMX-MicroNet Stack. The software provides an example of the following:
Interrupt-based ADC sampling engine
Automatic gain control
G.711 sound compression
Sound transmission over Ethernet
Web server interface for viewing sensor data
Storing in and serving web pages from CP220x Flash
Implementing a TFTP bootloader
