Embedded - CPLDs (Complex Programmable Logic Devices) have revolutionized the development of digital circuits, making them more user-friendly, reliable, compact and cost-effective. The EPM7064BTC44-7 field programmable logic device is one such example, and it is renowned in engineering circles for its versatility and reliability. This application note provides an introduction to the EPM7064BTC44-7, including a brief overview of its application field and working principle.

The main application field of the EPM7064BTC44-7 is digital signal processing. It is used as a powerful processor in Embedded Systems, as it is an idealized ‘gateway’ through which signals can be directed, split and routed to their respective outputs. The EPM7064BTC44-7 integrates this ‘gateway’ function with programmable logic, allowing it to be programmed to suit a variety of applications without the use of external components. This makes it ideal for low-cost, low-power and low-complexity applications.

The working principle of the EPM7064BTC44-7 is based on an on-chip field-programmable logic array (FPLA) structure. This structure allows users to program the EPM7064BTC44-7 with the desired logic functions, making the device highly customizable. The device contains two separate parts, the on-chip field programmable logic array (FPLA) and the embedded programmable logic control (EPLC). The FPLA is responsible for the actual programming of the device, while the EPLC is responsible for controlling and managing the programming process.

The FPLA is composed of a series of two-dimensional memory arrays. These memory arrays store the logic functions programmed by the user. Each FPLA array is capable of storing up to nine logic functions and is managed by an address register. The logic functions are then implemented through the associated logic gates by controlling the level of current flow. The FPLA is controlled by the EPLC. The EPLC controls the selection of the logic functions and their implementation in the memory array. Once the FPLA is programmed, the device can then be operated in either an ‘immediate’ or ‘delay’ mode.

The immediate mode enables the EPM7064BTC44-7 to execute logic functions as soon as they are programmed into the device. This makes it possible to construct complex logic circuits in less time. In the delay mo
