Embedded - CPLDs (Complex Programmable Logic Devices) provide a powerful alternative to conventional hardware-based design solutions. This article will discuss the application field and working principle of the ATF2500C-20GM.

The ATF2500C-20GM is a CPLD device based on the Altera MAX® architecture, and features two types of programmable logic blocks and two types of I/O banks, enabling faster and more efficient designs. The input to output delay measures less than two nanoseconds, and the maximum instruction length of 32 bits allows complex operations to be processed in a single instruction. It also offers a variety of features such as spread spectrum clocking support and application-specific design analysis.

The ATF2500C-20GM is suitable for a wide range of applications, from medical equipment, automotive control systems, industrial automation to factory automation, communication systems, and military systems. It is designed for use in low-power and low-voltage applications, making it suitable for battery-operated devices as well as environmentally friendly designs. It is designed for implementation in FPGA-based systems, allowing for fast system development and design iterations.

The working principle of the ATF2500C-20GM is based on the Altera MAX® architecture. It consists of programmable logic blocks and I/O banks, each of which is linked together using a routing grid. This grid consists of four quadrants, each connecting the input, output and logic blocks of the device. In addition, clocking resources are available for synchronizing the logic blocks and I/O banks.

The programmable logic blocks support a variety of functions such as arithmetic operations, shifting, and comparison. They can be connected together via the routing grid in order to create more complex functions. The I/O banks provide connections to external memory and peripherals, as well as input and output signals. These connections are made via the external pins of the device.

The ATF2500C-20GM is programmed via the JTAG (Joint Test Action Group) standard, which consists of a set of pins that allow the device to be “programmed” from an external source. The programming instructions are stored in the programming instructions storage array, which is accessible via the external pins. The instructions can be edited from the external source via the JTAG pins. This allows for quick changes and updates to the programming instructions.

The ATF2500C-20GM also supports a variety of features, such as a pulse width modulator, a digital oscillator, and a memory manager. These features allow for efficient and rapid system design. The pulse width modulator enables designers to control the width of pulses, while the digital oscillator supports oscillatory waveforms with a fixed frequency. The memory manager provides efficient access to internal memory, and its contents can be read and written from the external pins.

In conclusion, the ATF2500C-20GM is a powerful and versatile CPLD device featuring the Altera MAX® architecture and a wide range of features. It is suitable for applications ranging from medical equipment to factory automation, and its programming is based on the JTAG standard, allowing for rapid design iterations. Its features, such as the pulse width modulator and digital oscillator, also enable efficient system designs.
