The EPM7256BUC169-7N is a type of Complex Programmable Logic Device (CPLD) which is also known as an embedded logic device because it is designed with specific structures, namely look-up tables or logic elements. CPLDs are large scale integrated circuit devices, based on the field programmable gate array technology (FPGA). Due to their small size, CPLDs can be used to implement functions which would ordinarily require a much larger circuit.
The EPM7256BUC169-7N is a high-density device with a wide application field, featuring a low power consumption at VCC=3.3 V, and exceptional access speeds of 0.18 μsec. It contains 8K Logic Elements which are programmable, allowing a wide range of logic functions to be implemented. It has a 256 macrocell array, with dedicated flip-flops and I/O blocks, as well as a built-in ISP (In-System Programmable) flash ROM for storing user programs. Additionally, the CPLD supports several in-house and third-party programming languages such as VHDL, jEDEC, and AHDL.
An EPM7256BUC169-7N is commonly used in many applications within the consumer, industrial and automotive fields. It can be used to provide control and timing solutions, as well as state machines, gate-level designs and bus arbitrations. It is also used in field programmable gate array (FPGA) designs, often serving as a peripheral or within power supplier or switch designs. Furthermore, the CPLD can be used as a glue logic device, connecting disparate circuits and providing clock synchronisation between them.
The working principle of the EPM7256BUC169-7N is based on an internal architecture consisting of macrocells and lookup tables (LUTs). The macrocells are a combination of dedicated flip-flops and programmable logic blocks. The LUTs are largely responsible for the main logic operations, accepting four inputs and outputting a single result to the flip-flops. The internal architecture is programmed through a series of paths, defined by the user, which direct the logic blocks and LUTs how to operate and the outputs they should provide.
Once the logic patterns are established, the CPLD will sequentially test each of the components of the user-defined path and set the appropriate logic levels. In order to program the CPLD, the user only needs to define the desired logic pattern in a software environment and the CPLD will then translate this pattern into its corresponding logic schema. By using this design communications, complex logic functions become available with a limited number of components.
In conclusion, CPLDs offer an invaluable platform for implementing complex logic designs and the EPM7256BUC169-7N is a particularly versatile high-density device. With its extended application field, exceptional speed and low power consumption, this CPLD can significantly minimize circuit size and complexity, improve overall performance and maximize the reliability of a system.
