AT17C512-10CC is a one-time programmable memory configuration prom for FPGAs. Specifically, it is an 8-pin, 128K-bit CMOS device that is designed to program an algorithm into many widely used Field Programmable Gate Arrays (FPGAs). It is widely used in digital systems such as HDTV receivers, digital video recorders, set-top boxes and various industrial and vehicle applications.

The AT17C512-10CC is a simple, reliable, secure and low-cost configuration prom for FPGAs. It is one-time programmable, meaning it requires no additional external circuitry. This makes it well suited for applications that are not prone to frequent design changes and require secure configuration in the field. The one-time programability also eliminates the possibility of malicious tampering of the programming algorithm.

The AT17C512-10CC works by providing an off-chip nonvolatile storage device into which configuration data is programmed. This data is then read out by the FPGA as it is initialised. The programming of the configuration data is done by first initialising the AT17C512-10CC with the desired algorithm and then sending a conventional programming voltage waveform to the device. The AT17C512-10CC then stores the data in memory in a secure manner.

The working principle of the AT17C512-10CC is relatively simple. It consists of three main components: a processor, a memory and an external interface. The processor is responsible for receiving, decoding and transferring external signals to the appropriate locations in the memory. The memory contains the configuration data which is stored in the device. The external interface permits the programming of the device during system startup. It also provides the signal path between the device and the FPGA.

As mentioned earlier, the AT17C512-10CC is used in a wide variety of applications. It can be used in embedded systems, automotive, communications and industrial control applications where storing the configuration data on non-volatile media such as EPROM or EEPROM is not practical. It can also be used in HDTV receivers, digital video recorders and set-top boxes as it provides a secure configuration for protecting firmware from malicious changes.

In conclusion, the AT17C512-10CC is a reliable and low-cost configuration prom for FPGAs. Its one-time programmable feature ensures that the configuration of the FPGA is secure and tamperproof. The AT17C512-10CC is used in a wide range of applications and offers a cost-effective method of securely storing FPGA configuration data in the field.
