The XC1765ELSO8C is a configuration prom for FPGAs, and it is used to store and configure FPGA through the mode of non-volatile memory. The key to better understand its application field and working principle is to take a look at its features and components.

Features

The XC1765ELSO8C features low external fast access and SRAM read power consumption, an 8-bit high-speed bus for fast access, and internal page erasing and write enabling for data retention. Other features include asynchronous or synchronous input/output, independent control between control signals, level shifting for bus inter-connections, and high speed operation. It’s an effective way to extend existing FPGA systems and factors in cost, size, and speed.

Components

The XC1765ELSO8C memory module is composed of a series of components that all individually play a role in the module’s operation. This includes two 8-bit tristate inverter buses, one latch, two 8-bit buses, two inverters, two 8-bit OR gates, a filter element, and a PMOS power switch.

The data latch is used to hold the last word written over the bus so that the memory can be read multiple times without the need to transmit the same data again. The OR gate is used to control access to the data path, and it opens if at least one of the active control signals is asserted. The filter element filters the internal bus signals to avoid interference from the higher frequency signals on the bus that may cause erroneous operations.

Operating Principle

The XC1765ELSO8C uses three control signals (read, write, and erase) and two address signals to perform the various operations. To read the data from the memory, the read (RD) signal is asserted and the desired address is activated. To write data, the write (WR) signal is asserted and the desired address and data are simultaneously supplied. To erase the memory, the erase (ER) signal is asserted and the desired address range is specified.

The data is stored in a non-volatile memory that uses flash memory technology. It can retain its stored data even when the power is shut off, so it is well suited for configuration proms that need to provide permanent information. The read, write, and erase times are much faster than traditional PROMs, making it ideal for FPGA configurations.

Application field

XC1765ELSO8C is widely used in various FPGA systems. It can perform fast read and write operations, and the data can be stored even without the power supply. As a result, XC1765ELSO8C is used in applications that require high speed and low power consumption, such as automotive, aerospace, industrial, and medical technologies. It is also suitable for controlling electric motors, energy monitor systems, UAVs and drones, as well as robots and embedded systems.

Conclusion

In conclusion, the XC1765ELSO8C is an extremely effective configuration prom for FPGA systems. It offers low power consumption, fast read and write operations, and data retention even when there is no power supply. Its application field covers a wide range of industries, including automotive, aerospace, industrial, and medical technologies. It is well suited for controlling electric motors, energy monitor systems, UAVs and drones, as well as robots and embedded systems, and is an ideal solution for these types of applications.
