ATF1504AS-10AU100 application field and working principle Embedded - CPLDs (Complex Programmable Logic Devices)

Complex Programmable Logic Devices (CPLDs) are programmable logic devices used in embedded systems. The ATF1504AS-10AU100 is a CPLD that is used in the development of embedded-systems applications, such as programmable automation controllers and industrial robots.

Application Field

The ATF1504AS-10AU100 is an in-system programmable CPLD that features up to 2048 logic cells and up to 16 Gigahertz of internal performance. It is ideal for low-density system integration, such as in automotive, medical, industrial, and consumer applications. The device is designed for power savings, high performance, and cost savings.

Architecture

The ATF1504AS-10AU100 CPLD consists of 2048 logic cells arranged in an array of four columns and 512 rows. It is organized into four independent configurable blocks, or “arrays.” Each block consists of four columns of 128 logic cells and can function independently. The device is further divided into Core and Execute blocks. The Core block consists of 512 logic cells that are configured as macros providing the resource and control functions for the entire device. The Execute blocks consist of 1536 logic cells that are individually configurable for combinatorial logic, flip-flop functions, DFFs, and more. Each of the four Execute blocks also comes with two macro cells for addressing and controlling peripheral devices.

Functionality

The ATF1504AS-10AU100 CPLD is used to create state-machine designs, implement various algorithms, and develop advanced digital controllers. The device provides advanced functionality, including data buses, address buses, synchronized logic functions, advanced timing, multiple logic functions, and arithmetic logic registers. It also offers a wide range of logic elements, including 3250 programmable logic functions, 16 latches, and 12 programmable delay elements. In addition, it supports various technologies, including clock-gating, spread-spectrum, and frequency-adjustment as well as high-speed data layer/masking.

Programming

The programming of the ATF1504AS-10AU100 CPLD is accomplished using the Atmel ATFPGMAssist CPLD Designer tool, which features a comprehensive set of features for system-level integration and application development. The software provides an easy-to-use graphical user interface, project management features, and detailed timing data. The software supports a variety of programming media, including on-board programming, JTAG programming, and PIO programming. It also supports Single-Event Upset (SEU) damage mitigation and testing through a self-test bus.

Conclusion

The Atmel ATF1504AS-10AU100 CPLD is an ideal resource for embedded system development. It is a low-cost, low-power, and high-performance device that is easily programmable. It provides advanced features and capabilities, including a wide range of programmable logic elements, data buses, address buses, and integrated testing features.
