EPC1064LI20 is a high-performance memory configuration memory prom produced by Epc International Inc, which is widely used in FPGA. It can be used as a memory-related infrastructure component to enable FPGAs to access large amounts of data quickly, saving time and increasing the effectiveness of operations.
EPC1064LI20 is predesigned to provide the data required by program-capable FPGAs, available in off-the-shelf solutions that are more accurate, reliable and cost-effective than standard memory solutions.

Application field

EPC1064LI20 is a single-chip field programmable gate array (FPGA) memory configuration prom that is widely used in computing and information systems, embedded systems, communication systems, and aerospace and defense fields. The memory capacity is 64Kwords, with a word width of 20 bits, and a voltage range of 2.7-3.3V.
It is suitable for use in FPGAs that require data storage, such as processing and storage of data from sensors and actuator or field of image processing. It can also help to provide FPGAs with the necessary functions to control signals and crosstalk in systems that require precise electrical transmission. For example, transmitting information signals between different parts of circuit boards, or providing functions for high-speed data transfer such as video streaming.

Working principle

EPC1064LI20 is an application specific prom that combines memory and logic. The memory part takes up 64K words, and can read and write data in 20-bit words. Inside the device there are two blocks that control the reading and writing of data, one control logic and one data logic. The control logic is used to monitor the read and write commands input from outside and stored in the memory. The data logic decodes the input command and carries out the corresponding read and write operation. In terms of storage, it has eight 8K word pages, 8K x 16 words per page. By setting the four lowest address bits with an external write device, the 8K word page can be selected.
In addition, it also contains a verification logic block which will verify the data it stores according to a pre-set algorithm. This ensures the safety and accuracy of the data stored in the memory, avoiding memory data errors that may cause FPGA integrated circuits to malfunction.

Conclusion

EPC1064LI20 is a highly reliable and cost-effective memory configuration prom for FPGAs. Its 64K words memory capacity and 20-bit word width are suitable for many embedded systems applications. It can provide reliable and accurate data storage, and its verification logic can protect the data it stores from memory errors. With its wide range of applications and advantages, EPC1064LI20 is one of the seminal components of current embedded technology.
