Embedded - CPLDs, or Complex Programmable Logic Devices, perform logic operations and can be configured to implement various logic functions, such as sequential logic, state machines, address decoding and control signaling.EPM7128STC100-10N is a small-sized, 5V, moderate-density CPLD that contains two rows of 64 Macrocells each. Now, let’s explore the application field and working principle of EPM7128STC100-10N.

Application Field of EPM7128STC100-10N

The application field of EPM7128STC100-10N is essentially unlimited. This CPLD offers ample configuration options for customers’designs and find widespread application in automotive, consumer, industry, telecommunications and military electronics. Thanks to its high density and low power consumption, EPM7128STC100-10N is an excellent candidate for applications such as system control and monitoring, design prototyping and storage, data acquisition and motor control.

Working Principle of EPM7128STC100-10N

Every complex programmable logic device(CPLD) is comprised of two architectural components: in-system programmable logic array (PLA) and switch matrix, combined together to form the CPLD Core.EPM7128STC100-10N CPLD core is composed of two cells with overlapping configuration logic regions. In addition, the device includes sum-of-products logic and I/O cell look-up tables (LUTs), in which the logic operations and state setting of the devices are determined by the users’ design software. The device is configured with a one-time programmable (OTP) memory array and a volatile EPROM for reconfiguration. During operation, both memory arrays are configured with user-defined logic functions.

In order to use EPM7128STC100-10N in a design, the user has to provide the logic that defines the functionality of the device. Generally, the logic design is created using design software, such as Altera’s Quartus II. During the design process, the user defines the logic function and then links it to the CPLD for synthesis and place and route of the device to configuration files (VHDL/Verilog Language), which can be stored on an EPROM/E2PROM on board or as a software file. These configuration files are then used to program and configure the device.

EPM7128STC100-10N is a widely used embedded CPLD. It offers an ideal balance between cost, power, and density and is suitable for many embedded applications. Savvy engineering teams understand that they must program the device with the appropriate logic to ensure its reliable operation in their embedded design.
