Embedded CPLDs (Complex Programmable Logic Devices) are used in a variety of applications. The ATF1502AS-10AC44 is an example of an embedded CPLD used in a range of industries. This article will explain the application field and working principle of the ATF1502AS-10AC44.

The ATF1502AS-10AC44 is a low-cost, low-voltage, low-power, high-speed CMOS embedded CPLD. It is designed for multiple applications in consumer, telecommunications, consumer electronics, and automotive industries. It is used in the design, production, and test of high-speed and low-power systems. It is also commonly used for interface communication, storage control, motor control, ADC and DAC control, power supply control, audio and video processing, and system logic control. The device is suitable for a wide variety of applications such as consumer, automotive, industrial, communications, and medical systems that require low-voltage and low-power operation.

The ATF1502AS-10AC44 has the following main features: a maximum operating frequency of 80 MHz; programmable logic cells of 283–2194; maximum output delay of 0.45 ns; maximum asynchronous I/O of 8 MHz; logic unit of 8-bit slices with up to 8 macrocells; in-system programmable; and a single +3.3 V power supply with a low power consumption of 0.297 mA/MHz. In addition, it comes with an enhanced fuse array, which allows for maximum design flexibility and provides enhanced security.

The working principle of the ATF1502AS-10AC44 is based on the concept of using a programmable logic device. With the embedded CPLD, the user can create custom logic functions and combine them in a targeted way to produce the required result. This allows the user to implement complex systems that cannot be realized through standard logic components.

The device has two levels of logic blocks; the first level consists of logic slices, which contain up to eight macrocells. Macrocells can then be combined into more complex logic functions (arithmetic and tension controllers, multiplexers, etc.). The second level consists of I/O drivers and buffers, as well as programmable voltage detectors. The device also hosts non-volatile memory (NVM) for storing configuration data.

The device also has a built-in in-system programmable (ISP) circuit for downloading configuration data from an external memory device. This allows the user to program the device without having to remove it from the circuit. The clock is provided externally and is self-adjusted to ensure the best performance.

In conclusion, the ATF1502AS-10AC44 is a low-cost, low-power, and high-speed CMOS embedded CPLD, which is suitable for a wide variety of applications in the consumer, automotive, industrial, telecommunications, and medical systems. It is easy to program and can be configured using an in-system programming feature. With its advanced fuse array, the device provides superior flexibility and enhanced security. The device is widely used in the design and production of high-speed and low-power systems, interface communication, storage control, motor control, ADC and DAC control, power supply control, audio and video processing, and system logic control.
