The rest of the electronic components in the circuitry are shown in the image above. Two major semiconductor IC can be seen. 24C02 is a serial EEPROM memory manufactured by Atmel used to store the data. The data stored in this memory is not lost even when the power is turned off. VC0326 IC manufacture by Vimicro is a chip with many functions embedded in it. It has an 8- bit microcontroller, 10 bit imaging processor, JPEG encoder engine, inbuilt ADC, audio and video class USB support and complies with USB 2.0 protocols for transferring data to the PC. It collects the data from the image and the sound sensor, processes it and sends it to the PC using the USB.
