The AT24C512 provides 524,288 bits of serial electrically erasable and programmable read only memory (EEPROM) organized as 65,536 words of 8 bits each. The device鈥檚 cascadable feature allows up to four devices to share a common two-WIRE bus. The device is optimized for use in many industrial and commercial applications where lowpower and low-voltage operation are essential. The devices are available in spacesaving 8-pin PDIP, 8-lead EIAJ SOIC, 8-lead JEDEC SOIC, 8-lead TSSOP, 8-lead Leadless Array (LAP), and 8-lead SAP packages. In addition, the entire family is available in 2.7V (2.7V to 5.5V) and 1.8V (1.8V to 3.6V) versions.

This is schematic and Gerber files of PCB that is used for GSM alarm system. This is industrial-grade system with many features like 1-WIRE (iButton) interface, additional interface for video camera (UART JPEG camera is used), SD card to store pictures from camera and send them by GSM to remote mobile phone. Can be used as a reference design for anyone who wants to make own GSM alarm system system based on SIM300C module from Simcom.
