Introduction

The ISPLSI 1032E-100LJN is a Complex Programmable Logic Device (CPLD), an embedded logic device which enables users to program digital logic functions at the circuit level and to run multiple functions concurrently. The device facilitates the design of complex digital circuit applications and has a variety of rich features, making it well-suited for a wide range of applications.

Architecture of the ISPLSI 1032E-100LJN

The ISPLSI 1032E-100LJN is a device created with a Macro Cell Architecture. It takes advantage of a standard 01N625 (1Mbit) industrial memory technology integrated into the device in order to achieve higher levels of speed, power, and density. There are 1K to 128K macrocells on this device, which can be configured in a wide range of applications. The device is divided into two sections: the section containing the macrocells, and the section containing the other components necessary to feed the macrocells and read their output. The device is composed of 4096 macrocells, 4096 4-bit flip-flops, and 1Kx16 bit sram. The macrocells are further divided into blocks (each block containing 4K macrocells). There are 40 macrocell blocks, each having two priorities (low priority and high priority). The low priority levels correspond to the outermost macrocells and the higher priority levels are contained within arrays of smaller macrocells. This device also contains an array of four 4-bit x 16-bit configurable logic blocks (CLBs), where each CLB contains 4 combinatorial logic elements. The CLBs can be used to configure logic functions such as AND, OR, NOT, XOR and XNOR. This device supports asynchronous and synchronous reset and clock input functions, which enable high-performance operation.

Applications of the ISPLSI 1032E-100LJN

The ISPLSI 1032E-100LJN can be used to design a variety of digital circuit applications. It is suitable for applications requiring large amounts of data storage and relatively short data paths. Examples of this type of applications include computer peripheral controllers, communications and industrial control systems, laser printers and microprocessor-based embedded systems. It is also suitable for applications that require high-speed and timing-critical operations, such as ultrasound imaging, portable medical systems, digital signal processing, aerospace, industrial and automation control, automotive and digital communication systems.

Working Principle of the ISPLSI 1032E-100LJN

The ISPLSI 1032E-100LJN works similarly to other CPLDs. The user enters the desired logic equations and assigns signal parameters in the design environment. The design is then placed and routed, and the appropriate software compiles the logic and places it into the device’s macrocells. The macrocells are the building blocks of the device and serve as the primary elements in the logical design. The macrocells contain a logic array circuit (LAC) that takes as input either a logical input or the output from another LAC. This LAC can be configured in a range of applications from AND/NAND gates, OR/NOR gates and flip-flops to complex arithmetic and logic functions, counters, register files, and data selectors. The output of the LACs is then routed out of the macrocell and connected to the input of another LAC, forming a logic circuit. The logic circuit will execute logic operations, such as sequential and combinational operations, until it produces the desired output. The designer can program the macrocells to be synchronous or asynchronous, enabling applications to be tailored to the needs of the circuit.

Conclusion

The ISPLSI 1032E-100LJN is a powerful and versatile Complex Programmable Logic Device (CPLD). It contains an array of 4096 macrocells and four 4-bit x 16-bit configurable logic blocks (CLBs). Its macrocells can be used to create a wide range of applications from computer peripheral controllers and communications systems to microprocessor-based embedded systems and automotive electronics. The device can be programmed to be synchronous or asynchronous, allowing it to process large amount of data in fast and timing-critical operations. This makes the ISPLSI 1032E-100LJN an ideal device for a wide range of applications.
