Embedded - CPLDs (Complex Programmable Logic Devices) have become an integral part of many electronic systems due to their efficient size, greater reliability, and optimized power consumption. As time passes, the demand for smaller and more capable electronic devices increases, so does the requirement for CPLDs with improved operation, flexibility and portability. The LC4256V-75FN256BI device from Lattice Semiconductor is one such CPLD, having a dense array of programmable logic, plus a versatile array of inputs and outputs.

Built on a low power CMOS platform and with a 75MHz maximum clock frequency, the LC4256V-75FN256BI CPLD is ideal for a wide range of embedded applications. It has 256 programmable logic blocks and is able to support multiple logic and clock functions in a single unit. The programmable input and output characteristics allow the LC4256V-75FN256BI to be used in a variety of embedded applications, such as industrial control systems, embedded systems, communications and networking, and instrumentation and measurement. Moreover, due to its low power ability, it can be used in battery-powered devices as well.

The LC4256V-75FN256BI works by receiving user inputs from various signal sources and then routing them to the appropriate logic block. This is facilitated by the Main Interconnect Matrix, which links the logic blocks to the inputs and outputs. This allows the user to completely customize the CPLD to their specific application needs. The logic blocks then perform the programmed functions on the input signals, and the CPLD outputs the result of processing.

The LC4256V-75FN256BI also has the capacity to autorestart and autoself-test tasks to ensure that the CPLD is in optimal working condition at all times. Other features include a 256-Macrocell package, up to 36Kbits of dual port RAM, and a protection circuit which prevents damage to the CPLD due to excessive input/output currents.

Overall, the LC4256V-75FN256BI CPLD is a versatile, reliable, and low power embedded device which is suitable for a wide range of applications. Its flexible inputs/outputs and logic blocks, coupled with its ability to autorestart and autoself-test, make it a powerful CPLD for all embedded applications and suitable for use in both battery-powered and mains-powered applications.
