Embedded CPLDs (Complex Programmable Logic Devices) have become a popular choice for device designers, helping to increase the complexity and performance of electronic product designs. One of the most versatile CPLDs available is the LC4512B-10TN176I, which offers high-speed operation and flexibility, making it suitable for a number of applications. This article will outline the application field and working principle of this device.

Application field

The LC4512B-10TN176I CPLD is a general purpose programmable logic device, providing ideal solutions for a variety of applications. It is suitable for high-speed logic gate applications, such as Frequency Divider, Shift Register and Counter. Furthermore, the device can be used to perform large-scale combinatorial logic such as multiplexer, decoder and Boolean expression- to-decoder conversion. It is also suitable for applications in different interface communication systems such as USART, I2C, SPI, CAN-Bus and E2 etc.

Working Principle

The LC4512B-10TN176I CPLD is made up of several logic elements called logic cells, which are interconnected to form a product term. The logic cell has several components including a flip flop, a multiplexer, a product module and an address decoder. The flip flop is used to store and hold the output of the product module. The multiplexer is used to select the input signals to be applied to the product term. The product module performs the logic operation on the input signals to generate the output bits. The address decoder is used to decode the addresses of the input signals.

The LC4512B-10TN176I has an in-circuit programming facility, which allows the user to program the device without removing it from the circuit. This is done by using an external programming device such as an EPROM programmer. The programming device acts as an interface between the user and the LC4512B-10TN176I, transferring the user specified logic information to the device.

The LC4512B-10TN176I CPLD offers flexibility, convenience and versatility in the design and implementation of complex applications. It is suitable for a wide range of applications and can be used to create fast and efficient solutions for product developers.
