M5LV-512/256-20SAI

Embedded - CPLDs (Complex Programmable Logic Devices)

M5LV-512/256-20SAI is a type of complex programmable logic device (CPLD). CPLD is considered as a subset of field-programmable gate arrays (FPGA). Generally, CPLD is an integrated circuit (IC) programmed to synthesize complicated components or to implement complicated logic functions. It is characterized by having complicated and resource-sharing logic blocks, consisting of combination of multiplexers, read-only-memory (ROM) cells, programmable-logic-arrays (PLAs) and logic cells. CPLD can be reprogrammed frequently and allows easy integration of many complex logic functions into a single chip.

Application Field

M5LV-512/256-20SAI CPLD is used for several applications such as for designing integrated digital systems, motor control, networking, data acquisition, industrial-control. Its major application is in the industrial field, mainly as system designers or system integrators or to aid embedded system designers and generally used in hard wired control systems. It is used to replace a traditional circuit of logic gate which would otherwise require complicated IC designs. Primitive logic functions can be done with logic blocks and increase speed while reducing the number of chips required.

Working Principle

M5LV-512/256-25SAI CPLD works by interconnecting the inputs and output pins to the internal logic elements such as multiplexers, PLAs, ROM and logic cells. The outputs are addressed to cause specific functions to be performed. This process is called as device programming which is done mainly by wiring, software, or firmware. With programmable logic components, the designer can transform the logic challenges from complicated wiring to simple problem of programming logic. Some of the logic challenges are issues concerning implementation of complicated circuit computation, interconnection and new logic challenges, like parallel-to-series or series-to-parallel transformation and delay-insensitive design.

Conclusion

M5LV-512/256-20SAI CPLD is a multi-purpose logic device based on VLSI technology, usually used in industrial fields as a tool to replace traditional complicated logic gate circuit boards. It works by interconnecting input and output pins to the internal logic elements, which requires a programming process. It is cost-effective, reliable and fast, and can be used for solving complicated logic challenges with ease.
