Embedded - CPLDs (Complex Programmable Logic Devices)

The LC4256ZC-75TN100C is a Parallel Processing device, which is categorized as a Complex Programmable Logic Device (CPLD). This device is used to help consolidate and minimize the number of components required in any circuit. This device is a member of the Xilinx CoolRunner-II family, and it is a logic programmable device which facilitates user-programmable access to internal logic functions.

Application Field

The LC4256ZC-75TN100C device is used in a wide range of applications where programmability is desirable in order to quickly adapt to changing requirements. This device is well suited for functions such as microprocessor-based systems interfacing and general-purpose logic functions. The device offers flexibility, particularly in cases where it reduces the system\'s hardware cost and time of development. It is also ideal for applications that require fast response time, and does not require low-power operation.

Common applications for this device include embedded systems, industrial control applications, consumer electronics, communication equipment, measurement systems, and automotive electronics.

Working Principle

The LC4256ZC-75TN100C device is a low-power programmable device that combines high performance and large-function capacity. The internal architecture of this device features Non-volatile flash based user programming capability which can be used to configure the device with user custom logic. The programmable architecture enables a very high level of flexibility and versatility in designing the logic in the device.

The basic principle of operation of the device is based on the logic within the device being programmable with the help of special software (often called a "Programming Language") and a dedicated hardware design tool such as Xilinx ISE/Imager. The device can be configured to perform any desired function by connecting the inputs to the appropriate logic circuits internally, and this is done by writing a custom program (or "netlist") in the user programming software.

Once the program has been written, the user can then program the device by uploading the custom program to the internal memory of the device. This process is known as "Bitstreaming" and is the only way to configure the device with custom logic. Once the program has been uploaded, the device is now ready to be used in the intended system.

The LC4256ZC-75TN100C device has a standard 8-bit microcontroller bus architecture, which provides access to memory registers, DQPREG registers, and I/O registers. This device also features an on-chip oscillator circuit that provides a dedicated clock for the entire device, enabling it to be configured with accurate timing. The device also supports a wide range of external memory devices, including EPROMs, EEPROMs, SRAMs and DRAMs, to extend the operating capabilities of the device.

Conclusion

The LC4256ZC-75TN100C device is a highly versatile, low-power CPLD which is used in a wide range of applications where programmability and flexibility are desirable. Due to its low-power operation and support for external memory devices, this device is ideal for embedded applications such as industrial control, consumer electronics, and automotive electronics. The programmable architecture of the device enables users to create custom logic configurations, helping to reduce the number of components required in any circuit.
