It is also used for displaying digital signals, performing arithmetic operations and controlling multiple digital circuits.

The device is mainly used for digital signal routing and control systems. It is an important component in digital electronics, providing logic interface between the analog and digital parts of an integrated system. The LC4064B-5T100C CPLD is an efficient device for logic design in many applications like test and measurement instruments, transit system scheduling, telcom applications and process control machinery.

Working Principle

The LC4064B-5T100C is based on the reconfigurable logic slicing structure of programmable logic devices. It contains 8 logic slices and 5 National Semiconductor MICROWIRE™ logic array blocks (LABs). It also contains 12 registers, 18 multiplexers, 12 state machines and two data bus interfaces. The device is a versatile and reconfigurable programmable logic device that is capable of accommodating wide range of tasks and applications with improved time-to-market.

The CPLD works in a three-step structure, which includes configuration, mapping and device configuration. The first step of configuration is to program the device. The programming is done with a software development tools such as Altera’s Quartus® or Xilinx’s ISE. In this step, the design logic is defined, logic map is programmed, and the programming voltage and program enable polarity are set. Once the device is programmed, the second step is to map the design into the device. In this step, the user specifies the logic assignments to the logic slices, registers and MUXes. The last step is to configure the device.

Once the device is configured and mapped, it can be used for various application fields. It contains many programmable logic blocks which can be used to control data flow and timing. The device also contains a range of interrupt control and power management features. For example, it is capable of detecting a fault condition, setting a reset signal and disabling certain parts of the system. It can also control the power to individual blocks and reset the system when a power failure occurs.

The LC4064B-5T100C CPLD is a versatile device for logic design and control systems, with numerous advantages over standard discrete logic blocks and other programmable logic devices. With its high density and flexible design, it is an ideal choice for complex digital systems in a wide range of applications.
