The Atmel® ATSHA204A is a full turnkey security device. It includes a 4.5Kb EEPROM divided into 16 slots. This array can be used for storage of keys, miscellaneous read/write, read-only, password or secret data, and consumption tracking. Access to the various sections of memory can be restricted in a variety of ways and then the configuration locked to prevent changes.
Access to the chip is through a standard I²C interface at speeds up to 1Mb/sec. The chip also supports a single-wire interface that can reduce the number of GPIOs required on the system processor and/or reduce the number of pins on connectors. It is compatible with most UART or serial I/O controllers. System integration is eased with a wide supply voltage range and an ultra-low sleep current of less than 100nA.
