Embedded technologies are everywhere, from smartphones to industrial manufacturing. CPLDs (Complex Programmable Logic Devices) are highly useful devices that combine the powerful capabilities of FPGAs with the reliability and cost-effectiveness of ASICs. The ISPLSI 1024-60LJ is a classic example of such a device, providing dense integration of logic functions, interconnects and product-level capability. This article will discuss the application field and working principle of the ISPLSI 1024-60LJ.

Application Field

The ISPLSI 1024-60LJ is an LJ (large-junction) CPLD with 1024 macrocells and 32 I/O banks. It can be used in a wide variety of embedded applications, including industrial, automotive, medical, and consumer applications. In particular, it is suitable for applications requiring high reliability, dependability, and low power consumption. Further, the device is designed with a versatile and advanced configuration memory, allowing for in-system reconfigurability, up to a single cycle. As such, the ISPLSI 1024-60LJ can be used in a wide variety of applications requiring in-system reconfigurability.

Working Principle

The ISPLSI 1024-60LJ is based on a programmable array logic (PAL) architecture, which is made up of two distinct components -- the macrocell array and the configuration memory. The macrocell array consists of 1024 macrocells, which are interconnected by dedicated interconnects that allow for the implementation of digital logic functions. The macrocell array is connected to the configuration memory, which stores configuration bits for each macrocell. The configuration memory is updated via an SPI- or JTAG-coupled device, after which the logic gates are electrically programmed.

In addition to the programmable logic gates, the ISPLSI 1024-60LJ also contains a number of other elements designed to reduce system cost and improve overall device performance. These elements include mixed-voltage translators, buses with up to 32 bits each, EEPROMs, synchronous reset circuits, and dedicated clock buffers. Together, these components enable the device to be integrated into complex embedded applications with reliable and efficient performance.

Conclusion

In summary, the ISPLSI 1024-60LJ is a highly versatile and reliable CPLD device. It is designed with a powerful macrocell array and advanced configuration memory, making it ideal for applications requiring in-system reconfigurability. Moreover, the device is equipped with various elements that help reduce system cost and promote overall device performance. As such, the ISPLSI 1024-60LJ is an ideal choice for embedded applications in a wide range of industries.
