Complex Programmable Logic Devices (CPLDs) are integrated circuits made up of gates, registers, and programmable term-defined connections between gates and also registers. They provide more gates, registers and interconnects than conventional Field Programmable Gate Arrays (FPGA) and are used for high-density applications.

The ATV2500BQ-20KC CPLD is a 20-kilobit asynchronous first in first out (FIFO) device with a flexible, easy to use architecture. It is designed for use in many digital communication applications such as; streaming video and audio, communication control, modem control, image processing, or digital still image transmission. The device contains a local 8k-bit register file, three independent global clock and data paths, a gigabit transfer buffer and an advanced high-speed burst controller.

The ATV2500BQ-20KC CPLD is an ideal solution for applications that require high-density capability and performance, and its features make it a perfect choice for streaming audio/video, communication control, modem control, image processing, or digital still image transmission applications. The device includes a flexible, easy to use architecture that minimizes external components, allowing for faster system prototyping and development.

The ATV2500BQ-20KC CPLD can be used to implement logic functions such as controlling access to the memory, controlling data interchanges, and creating logic gate functions between the registers, among other things. The device can support up to five external address input pins to enable burst transfers, as well as three clocks for various aspects of the operation. The clock rate is adjustable and can be increased based on the application requirements. The Global Clock feature allows for multiple instances of the device to be synchronized together.

The ATV2500BQ-20KC CPLD utilizes a single-phase clocking with a two-edge transition. This clock mode allows for various clocking speeds over different periods of time. Additionally, the device features three independent programmable global clock outputs, allowing a wide range of clocking rates to be implemented without performance degradation. The device also provides a configurable timing register that can be used to set up specific operations when using multiple devices.

The ATV2500BQ-20KC CPLD also features an on-chip memory controller that enables direct memory access (DMA). This allows the device to access a given memory address without having to go through a CPU. The device includes both static and dynamic RAM features, making it suitable for a large number of applications. Additionally, the device includes a third-party bus (VPT) interface for increased data transfer speed.

The ATV2500BQ-20KC CPLD utilizes non-volatile EPROM technology for its on-chip program storage. This allows for fast program updates and eliminates the need for re-programming when changes are required. The on-chip program memory can be used for storing user-defined pipeline codes, interrupt vector routing table, vector layout table, logic and path tables, or any other code or data.

In summary, the ATV2500BQ-20KC CPLD is a high-density, easy-to-use, and feature-rich device that is perfect for a variety of embedded applications. Its flexible architecture makes it an excellent choice for both communication control and streaming audio/video applications. Additionally, its on-chip memory controller, configurable timing register, and global clock features enable the device to be used in a wide range of applications.
