Complex Programmable Logic Devices (CPLDs), sometimes referred to as Programmable Logic Devices (PLDs), are integrated circuits that provide a more efficient and cost-effective solution to combining several digital components into one device. The CY37128VP160-83AXCT is one such CPLD. This article will explore its applications and working principle.

Applications

The CY37128VP160-83AXCT is primarily used for timing and control applications, such as in automotive, communications, consumer and industrial applications. It is designed for high reliability and performance with minimal power consumption, and it meets Automotive Electronics Council (AEC) standards for automotive applications.

The CY37128VP160-83AXCT integrates 16input/output blocks, eight programmable clock divider blocks and four programmable polarity multiplexers. This CPLD is particularly suited for applications that require a high-performance solution for fast switching high-current loads. It is also ideal for implementing very sophisticated and time-critical logic tasks.

The CY37128VP160-83AXCT is compatible with the industry-standard JEDEC 22-pin Small Outline Integrated Circuits (SOIC) package, enabling it to be integrated into existing production line designs. It is also pin-compatible with the previous CY37128VP160-73AXCT, making it easier to upgrade and maintain legacy systems.

In addition to its standard applications, the CY37128VP160-83AXCT also offers flexibility that allows it to be quickly and easily programmed for custom designs. This makes it an attractive prospect for design engineers who need a versatile and powerful CPLD for their applications.

Working Principle

At its core, the CY37128VP160-83AXCT is a field programmable logic device (FPLD). This means that its logic is programmed by the user with a software suite from the manufacturer, without the need for soldering. The user can define the logic map and the mapping of pins, which allows the CPLD to complete complex timing and control tasks. The CPLD also contains a fixed, read-only memory that stores the programming information and makes it nonvolatile across power cycling.

The user can use the manufacturer’s software suite to design and simulate their logic, as well as compile and verify their code. Once the programming is completed, the software suite allows the user to download the data to a device programmer which then programs the CPLD. The device programmer provides good programming accuracy and stability, making it ideal for time-critical operations.

The CPLD also features an integrated oscillator that can be used to create a clock for faster operation. The clock can be scaled down or up according to the needs of the application, allowing the designer to tailor the clock rate for different operations.

The CPLD also contains an array of input and output pins that allows the user to program different connections to the outside world. This makes it easier for designers to interface with external components and systems, allowing for far greater flexibility in their designs.

Conclusion

The CY37128VP160-83AXCT is a powerful and efficient CPLD that is suited for many time-critical applications such as automotive, consumer, industrial and communications. It is highly flexible and is programmable with a software suite from the manufacturer, allowing designers to tailor it to their exact needs. The integrated oscillator and array of input and output pins make it easy to interface with external components and systems. The CY37128VP160-83AXCT is a great choice for many design engineers.
