Embedded - CPLDs (Complex Programmable Logic Devices) is a type of integrated circuit that can be programmed to perform a specific set of functions. The XC9536-15PC44I is an example of such a device and is used in several applications. In this article, we\'ll discuss the XC9536-15PC44I application field and working principle.

The XC9536-15PC44I CPLD is an 18V-driven, 20-pin, 0.35-micron CMOS voltage-level application that operates from -40°C to +85°C. It is designed for industrial control, communication systems, networking and multimedia applications. With its integrated design, it provides high-speed operation and minimized power consumption. Being field programmable, it can be customized to meet a variety of application needs.

The XC9536-15PC44I CPLD consists of two components: the logic array and the IO (Input/Output) block. The logic array is composed of two sections, the macrocells and the control functions. Each macrocell contains four AND gates, four OR gates, and two flip-flops. There are 64 macrocells in the logic array. The control functions are mainly clock signal routing, reset distribution, power on reset generation, program port dedect functions, and global signal distribution. The IO block contains the registers, drivers, receivers, and other components necessary for interfacing with external devices.

The XC9536-15PC44I CPLD uses a Static Sequential Logic or SSI architecture. This type of architecture is based on devices that react to digital inputs and control outputs with the help of feedback circuits. This architecture ensures that the device operates only when certain criteria have been met and that the outputs remain in their predetermined state until the criteria have been met again. This helps to reduce turnaround time, increase device reliability, and extend product life.

The XC9536-15PC44I CPLD features various functions such as a two-dimensional ROM (Random Access Memory) and a High-Speed Bitslicer. The ROM is used to store program instructions. It can store up to 4K instructions. The High-Speed Bitslicer helps to quickly detect and capture the contents of external memory. This helps in enhanced system performance and reduces the power consumption by up to 40%. It also offers high-end programmable logic functions like Interrupts and Delay.

When configuring the XC9536-15PC44I CPLD, the user can choose from two programming languages: VHDL (Very High-Level Design Language) and Verilog. VHDL is an IEEE-standardized hardware description language that can be used to design digital systems. It provides an accurate and comprehensive way of expressing the hierarchy of digital designs. On the other hand, Verilog is a hardware description language used to design both FPGAs (Field Programmable Gate Arrays) and CPLDs. It is more concise compared to VHDL and can be used to design both simple and complex digital systems.

The XC9536-15PC44I CPLD consumes very low power and offers high speed and reliability. Its versatile programming interface and wide range of functions make it suitable for many applications such as automotive, industrial control, networking, communication, and multimedia applications. With its in-built features, it can significantly reduce system cost and product life cycle.
