Embedded CPLDs (Complex Programmable Logic Devices) are electronic devices used to interface and control electrical and electronic circuits. The M5-512/160-6YC is an Embedded CPLD specifically designed to be used as a device programming and general purpose controller. This article details its application field, working principles, its advantages over other CPLDs, and how to program and interface it with a system.

Application Field

The M5-512/160-6YC is a programmable CPLD meant for general purpose applications, including data acquisition, signal processing and control, communications, and logic interfacing. It is ideal for applications where existing CPLDs are not suitable, such as those requiring at least 512 macrocells. For instance, it can be used to implement complex Boolean integrals in hardware, and to develop synchronous application interfaces. It can also be used to construct sophisticated real-time control systems.

Working Principle

The M5-512/160-6YC is composed of a Programmable Logic Array (PLA), which is used to store and process digital logic expressions. It is also capable of performing simple digital feed forward control functions. The data is entered via a 16-bit address bus, which allows for up to 256 individual bytes of data. This data is then processed using 16 PLA elements and 8 two-input Boolean gates. The result is output via the data bus. This system can operate at up to 10MHz if properly configured.

In addition to these functions, the M5-512/160-6YC features 2Kbytes of programmable logic configuration memory. The logic configuration memory can be reconfigured on the fly, allowing the user to quickly adapt the logic on the fly depending on the application requirements. The CPLD can also be configured to act as a master or slave on the I2C bus, giving it the capability to control peripheral devices.

Advantages

The M5-512/160-6YC has several advantages over other CPLDs. One of its key advantages is its small size, which allows for more efficient programming and debugging. It requires minimal external components for proper operation, reducing overall system complexity. Its high integration density allows for the implementation of multiple logic functions in one device, resulting in a much smaller overall package. The CPLD has the ability to operate at frequencies up to 10MHz — allowing for better throughput and greater efficiency.

The M5-512/160-6YC also has the ability to be reprogrammed without the need for a dedicated controller, making it ideal for applications requiring frequent optimization, such as automated test systems. Its strong reliability and stability ensures that the logic functions within the device remain optimal over time, making it a great choice for mission-critical applications.

Programming and Interface

The M5-512/160-6YC can be programmed via the C compiler and development software of your choice. The C compiler can then be used to program the device with the logic required for your system. The device also has an on-board JTAG interface, which can be used for programming as well as for debugging. This makes it possible to quickly modify and optimize logic functions without the need for external components or additional hardware.

Once the device has been programmed, it can be connected to the system using either a 10-bit bi-phase bus, a 30-pin serial interface, or the I2C bus. The bi-phase bus is the most commonly used interface, and provides a fast two-way communication for transferring data to and from the device. The serial interface provides more options for connecting peripherals and connecting the device to a PC. The I2C bus is especially useful for interfacing with external sensors and other peripheral devices. It is also used to easily transmit status and error messages.

Conclusion

The M5-512/160-6YC CPLD is a powerful and versatile device, and is an ideal choice for many embedded applications. It provides a cost-effective solution with great performance and reliability. It can easily be programmed and interfaced with a variety of systems, and its features make it an ideal choice for applications requiring high-speed control and logic operations.
