Embedded systems employ a number of technologies to enable the implementation of sophisticated tasks, to store data and reduce costs, and to increase energy efficiency. CPLDs (Complex Programmable Logic Devices) are one such technology that can help with these goals. The 1016-60LJI from ISPLsi is a CPLD designed for various embedded applications. This article discusses the applications and working principle of this device, to provide readers with a better understanding of the technology.

Applications

The 1016-60LJI CPLD is designed for both simple and complex digital applications. It provides 16 macrocells that can be configured to implement custom logic functions and state machines. This makes it suitable for applications like system monitoring, control, power management, and communications. Additionally, it includes Flash-based FPGA (fpPLA) technology, allowing users to download, store, and reconfigure the logic functions implemented on the chip.

The 1016-60LJI also features a powerful low-voltage parallel I/O (LVPI) interface. This allows for a fast connection to external components like memories and processors, as well as straightforward control of pulse-width modulation (PWM). All of these features make the 1016-60LJI an excellent choice for a variety of embedded applications, ranging from automotive to industrial.

Working Principle

The working principle of the 1016-60LJI CPLD is based on the concept of configurable logic blocks (CLBs). Each CLB contains a set of logic elements, such as an AND gate, an OR gate, and a register. By connecting CLBs together through configurable interconnects, users can create custom logic functions. In addition, the device provides control logic elements, such as a programmable counter and RAM. This allows users to implement more complex logic functions, such as state machines and arithmetic operations.

The 1016-60LJI also features a configurable scan chain, which enables users to rapidly test and debug the device\'s operation. This feature also allows engineers to rapidly write, read, and store logic functions in the device\'s Flash memory. Additionally, the device can be programmed using a standard JTAG interface. This makes it easy to update the device\'s firmware and to download program updates.

Conclusion

The ISPLsi 1016-60LJI CPLD is a powerful and versatile device, suitable for a wide range of embedded applications. It features 16 macrocells and a range of control logic elements that can be connected together to implement custom logic functions. Additionally, it provides a configurable scan chain and a JTAG interface, allowing it to be rapidly tested and updated. Embedded systems can benefit from the speed, flexibility, and ease of use offered by the 1016-60LJI, helping to reduce costs and improve performance.
