Memory - Configuration Proms for FPGAs

FPGAs are a type of digital integrated circuit that have become increasingly popular in recent years due to their fiercely competitive advantage over traditional circuit boards. FPGAs are extremely flexible, taking the form of programmable logic blocks that are linked together to create a network of complex digital logic. To make the most of this functionality, many electronic systems now rely on configuration PROMs (Programmable Read Only Memory) to load the necessary data into the FPGA.

The AT17C128A-10JC configuration PROM is an example of such a product. This part is offered by Atmel, a well-known provider of integrated circuits, and it has become a popular choice for a variety of applications. In this article, the main features of the AT17C128A-10JC are outlined, along with its possible application fields and working principle.

AT17C128A-10JC: Features and Specifications

The AT17C128A-10JC is a CMOS-based product that is used to configure FPGAs from Atmel. It consists of an 8Kx16 bit array of non-volatile memory and it is capable of supporting two different bus configurations. The two bus configurations are the 16-bit address and data bus configuration, which is designed for the AT17C128A, and the 8-bit configuration when the address and data buses are multiplexed. The device is ideal for FPGAs that require multiple data bytes in order to program, such as those from Atmel.

In terms of its physical characteristics, the AT17C128A-10JC comes in a standard 8-pin SOIC package complete with power and ground pins. This is convenient for applications where space is at a premium. The device has an Ambient Operating Temperature range of - 40°C to +85°C and can withstand a wide range of environmental conditions, providing robust operation in tough industrial environments.

Applications of the AT17C128A-10JC

As mentioned, the AT17C128A-10JC is designed for use with FPGAs from Atmel. It can be used for a broad range of applications in a wide range of industries. These include automotive, medical and industrial applications, as well as communications and consumer electronics.

The device is particularly suited for applications that require high levels of configurability. For example, the AT17C128A-10JC can be used to configure FPGAs in systems where complex logic functions are required and where flexibility is paramount, such as in industrial process control, healthcare or transportation applications.

Working Principle of the AT17C128A-10JC

The AT17C128A-10JC is capable of storing up to 64 kilobytes of data. This data can be used to configure the FPGA as desired. The device is programmed using a standard PROM programmer and can then be used to configure the FPGA during system startup. The device can also be reprogrammed in-system using the JTAG interface.

When the FPGA is powered up, the AT17C128A-10JC will be read to determine the configuration data that should be loaded into the FPGA. This data is then used to configure the FPGA according to the programmed data, which allows for the desired levels of flexibility and reconfigurability in the system.

Conclusion

The AT17C128A-10JC is a popular configuration PROM suitable for a wide range of FPGA applications. This device from Atmel offers 8 KB of non-volatile memory and can be programmed quickly and easily with a PROM programmer. The device is reliable and robust, with a wide operating temperature range, which makes it perfectly suited for many different industrial applications.
