LC4128V-75TN128E

The LC4128V-75TN128E integrated circuit (IC) is an example of an embedded CPLD (complex programmable logic device). CPLDs are programmable logic devices (PLDs) that have a greater range of functionalities than traditional PLDs. They are used in embedded systems for things like system on a chip (SoC) and programmable logic array (PLA) configurations. CPLDs are available with a variety of logic implementation such as logic arrays, gates, data registers, and other logic functions.

Application Field

LC4128V-75TN128E is suitable for applications where initial programming is required, but also dynamic updates are needed. Its characteristics make it well suited for use as a control engine in a wide range of applications, such as medical devices, communication systems, microcontrollers, automotive systems, and many others. CPLDs are used in almost every embedded system because they can be easily programmed and reprogrammed at any time to suit the changing needs of the application.

The main advantage of CPLDs over traditional programmable logic devices is their ability to store a large amount of data in a single device. This data can be quickly processed by the device, allowing for faster responses in embedded systems. The LC4128V-75TN128E is particularly well suited for embedded systems because it has a low power consumption and a high level of functionality.

Working Principle

The LC4128V-75TN128E CPLD operates in much the same way as a traditional programmable logic device. When an input signal is received, the device triggers logic gates that enable a predetermined set of outputs. The logic gates store the configuration data and then interact with the input signal to produce corresponding outputs. Depending on the configuration set, the output may be an electrical signal, a digital bit, or an addressable memory location. This makes the device extremely versatile, as it can be used to control various aspects of an embedded system.

The LC4128V-75TN128E is programmed using the industry standard JTAG (Joint Test Action Group) interface. This interface is used to write the configuration data to the device, ensuring that the device is programmed correctly. The device is then able to process the inputs and produce the outputs as specified by the programming.

Due to its low power consumption, the LC4128V-75TN128E is well suited for use with battery powered devices. The device has low quiescent current requirements, and its low power operation makes it ideal for devices that have a long life on a single battery charge. The device is also easy to configure and reprogram, making it useful for embedded systems that are undergoing frequent updates.

Conclusion

The LC4128V-75TN128E is an example of a CPLD, which is a type of programmable logic device. The device is well suited for use in embedded systems due to its low power consumption and flexibility. Its ability to store and process large amounts of data makes it an ideal choice for systems where dynamic updates are frequently required. The device is programmed via the industry standard JTAG interface, and its low quiescent current requirements make it suitable for battery powered devices.
