Embedded engineers often need compact and versatile integrated circuits that can be reprogrammed as needed, construction sites managers often install safety-critical equipment requiring field-configurable programming. And that’s where Complex Programmable Logic Devices (CPLDs) come in. CPLDs are integrated circuits with multiple input and output pins that can be reprogrammed to perform various operations in the embedded system. Along with these, the CPLDs offer increased speed and design flexibility, making them suitable for a wide range of applications.

The EPM7160ELC84-12, a CPLD from Altera, which incorporates up to 144 registers and is organized into four banks of 372 macrocells each, is a perfect example. With its advanced design flexibility, it is suitable for multiple applications. In this article, we’ll look at the application field and working principles of the EPM7160ELC84-12.

The EPM7160ELC84-12 is widely used in multiple embedded projects, and its application fields include: communication interface, data acquisition, digital signal processing and control, memory expansion and interface, logic control, networking, and automotive embedded systems.

The EPM7160ELC84-12 is based on an advanced architecture with four 501 x 372 banks of enhanced macrocells, two I/O blocks of 363 x 597 columns, and a dedicated clock block of 162 x 37 columns. It also incorporates up to 72Kbytes of RAM, and several features such as 24 Non-Volatile Memory (NVM) ports, programmable FlashROM, and 4 Power-on reset (POR) sources. Its low power consumption and adaptable design make it suitable for a variety of applications.

In terms of working principle, the EPM7160ELC84-12 can be programmed to perform a wide range of tasks, including numerical and logic computations, as well as regular math functions. The CPLD can also be used for interfacing externally connected hardware and communication protocols, since it incorporates feature-rich I/O blocks and communication interface logic. It can also be programmed to access and control sophisticated memories such as DDR, NOR-flash, and SRAM. As an example, the EPM7160ELC84-12 can be programmed to reprogram itself on power-up, thereby allowing complete remote control and configuration of the device.

Moreover, the EPM7160ELC84-12 is suitable for designs requiring circuit speed and power optimization, as its memory access times of 5ns or less make it highly capable of performing fast data fetching, decoding, and address sequencing tasks on-the-fly. Furthermore, its two 64-bit programmable SRAMS and four 64-bit FIFOs enhance the device’s ability to perform address- and data-driven memory access operations.

In summary, the EPM7160ELC84-12 is a powerful and versatile CPLD from Altera, and its advanced design makes it suitable for a wide range of embedded applications. Its low power consumption and first-class performance enhance its ability to work in demanding applications such as networking, automotive, and communication. On top of that, its programmability allows this CPLD to synthesize complex algorithms, complex memory access operations, and custom configurations, making it a one-stop solution for even the most demanding embedded projects.
