Complex Programmable Logic Devices (CPLDs) provide users the ability to integrate embedded features that have previously been impossible. The EPM7512BUC169-10, developed by Altera, is a CPLD that is specifically designed as a high-performance, non-volatile and cost-effective device option for embedded applications.

Application Fields

The EPM7512BUC169-10 can be used in a variety of embedded applications, including:

• Industrial control, automation, instrumentation and test systems
• Networking, communication and multimedia systems
• Computer and peripheral systems
• Wireless, consumer and portable systems

• Office automation and automotive systems

In addition, this device can also be used in a variety of applications such as networking, communications and multimedia, digital audio, aerospace and defense systems, as well as medical devices where enhanced control and higher levels of integration are required.

Working Principle

The EPM7512BUC169-10 is a CMOS-based device with two logical blocks: the Logic Array Block (LAB) and the Programmable Interconnect Block (PIB). The device allows for efficient logic connections, allowing the device to integrate complex combinatorial and sequential logic and store program algorithms up to 28K logic elements.

The user-programmable LAB includes four resources: simple programmable logic elements (SPLEs) which serve as AND gates, flip-flops, multiplexers, and elements that incorporate these and other functions. Each SPLE is capable of implementing any digital logic function and can hold up to 10 binary inputs and 1 binary output. While the LAB allows the user to implement logic, the PIB allows the user to route the signals among the various logic functions implemented in the LAB.

The PIB implements four resources used to program the routing of signals on a device-wide basis. The four resources are: Switchboxes, which are used to connect the logic functions to each other; Programmable Nodes, which help route signals between Switchboxes; Programmable Interconnects, which allow the user to selectively route signals from output pins to LAB logic functions; and Tri-state Buffers which are used to control the output of CLBs from external devices.

The device contains four modes of operation, allowing it to be programmed to implement a variety of applications from high-speed routing to device-level interconnects, as well as general-purpose logic functions. These modes of operation enable the placement and routing of logic resources on the device for greater design flexibility.

In addition, the device is equipped with an optional MARIE interface that allows the device to be programmed using the MARIE language, providing users with powerful logic design features and functionalities.

Conclusion

The EPM7512BUC169-10 is a cost-effective CPLD that has been specifically designed for embedded applications. The device is easy to use, flexible and provides users with a robust range of features and functionalities. In addition, the device is capable of complex integration calculations, providing users with a variety of options for implementing logic functions in their embedded systems.
