Embedded - CPLDs (Complex Programmable Logic Devices) include state-of-the-art programmable logic device families such as EPM7128EQC100-12. This device provides features such as high-speed I/O, very small pin counts, 128 macrocell array, and ultra-low power consumption. As a result, EPM7128EQC100-12 is suitable for various applications involving low-power and limited space requirements.

In particular, EPM7128EQC100-12 is useful for applications such as high-speed LAN switches, digital video encoders, and remote control of machines and devices. Other applications like simple data converters and peripheral devices are also feasible with this CPLD.

The architecture of EPM7128EQC100-12 employs logic array blocks (LABs) of 128 macrocells each. This system has eight macrocell LABs to provide a total of 1,024 macrocells and 32 I/O blocks to output/input signals and data.

The EPM7128EQC100-12 device allows engineers to program the logic array and I/O structure,which simplifies the design process and reduces time-to-market. The device supports commercial programming hardware and software tools, offers secure bitstream protection, and enables remote field programming.

The working principle of EPM7128EQC100-12 is fairly simple. The information is stored into the device\'s SRAM and each time after power reset the SRAM enables a fast loading and start up of the logic part of the design. Once the design is loaded, the logic will continue to run until the power is reset or the configuration changes.

The device supports both synchronous and asynchronous designs. Synchronous logic elements are implemented by the system clock signal and asynchronous elements by the CE (Chip Enable) signal. The system clock signal is input from an external pin. By using this signal with correct phase shift and level, the logic array is configured for internal registers and logic operations.

The logic array is implemented using AND/OR plane, which is programmed with synchronous or asynchronous control. This plane allows the user to construct arbitrary logic functions and configurations. The I/O ports are controlled on both the synchronous and asynchronous plane. This allows the user to configure ports with different types of logic, generating different functions.

EPM7128EQC100-12 is a very useful CPLD device for various applications requiring low power and minimal size. Its simple working principle and versatile architecture make it a desirable choice for embedded projects with limited space and power constraints.
