Complex Programmable Logic Devices (CPLDs) are integrated circuits that are designed to provide quick, low power solution for digital logic applications. They are increasingly used in embedded systems and can be used to decrease component count and programmability.

The CY37064P84-154JXI is a Complex Programmable Logic Device from Cypress Semiconductor that is designed for easy implementation in embedded systems using a Configurable Logic Array (CLAS). It has 84 pins, with the first 54 pins being the centralized input/output pins.

The CY37064P84-154JXI has two main application fields. First, it can be used as a Digital-to-Analog Converter (DAC). It has an internal 8-bit resolution and a maximum output voltage of 12V. By combining the CY37064P84-154JXI with an external reference voltage and resistor, it can provide an accurate analog output.
Second, the CY37064P84-154JXI can be used as a low power, programmable logic device. It has 8 k-bit of on-board volatile memory, allowing for program changes without external memory. It has 8 high-speed logic blocks that can be divided into capture and output rail sections with up to 14 levels. The device also has a programmable input and output for interrupt purposes.

The CY37064P84-154JXI also has a specialized packet mode for high-speed, low-latency communication on a serial bus. It can operate with up to 8 bytes of data per frame and has an adjustable internal clock source.

A distinct feature of the CY37064P84-154JXI is its low power consumption. It features full cycle dynamic power control, a power-on reset circuit, and a power-up delay circuit to ensure a low operating current.

The CY37064P84-154JXI is also programmable, making it a versatile solution for embedded systems applications. It comes with an extensive library of configurable functions that can be modified using an intuitive graphical user interface to better suit specific design requirements. In addition, the device supports a variety of programming languages including VHDL and Verilog.

The working principle of the CY37064P84-154JXI is simple but efficient. It is configured by connecting a programmable logic array (PLA) to a simple programmable logic array (SPLA) containing multiple logic blocks. The PLA takes in a combination of input signals and produces one or more output signals depending on their logical states. The SPLA is used to connect the outputs of the PLA to the outputs of other logic blocks and other components in the system. In addition, the device has a feedback loop, so any logical changes can be applied automatically.

The CY37064P84-154JXI device is therefore an efficient and flexible solution for low-cost embedded systems. It is an ideal choice for high-speed, low-power applications as it can offer uninterrupted operation with minimal power consumption.
