Working Principle

The working principle of the EPM7064QI100-15 CPLD is based on the use of various configurable logic blocks (CLBs) to implement logic functions. Each CLB consists of a four-bit look-up table (LUT), a four-to-one multiplexer, and a register. The LUT can be used to implement a wide range of functions, from basic AND, OR and XOR gates to more complexcombinatorial and sequential functions.

The multiplexer can be used to route the output of the LUT to the output of the CLB. On the other hand, the register can be used to store the result of the LUT, as well as to implement logic functions such as D and D-type flip-flops. The CLB also includes additional registers that can be used to store additional input and output signals that are used by the LUT.

The EPM7064QI100-15 CPLD can be programmed through the use of the JTAG port. The device also has a SPI port that can be used to further configure and control the device. The device also has various test modes that can be used to check the correctness of the program loaded on the device.

Conclusion

The EPM7064QI100-15 CPLD device is an efficient, low-cost logic solution for building a variety of applications. It can be used in data logging, signal conditioning, I/O control, embedded processor systems, motor control, power management and fault detection. The device is programmed through the use of the JTAG port and features additional firmware and test modes that can be used to check the correctness of the program loaded on the device.
