An embedded system usually is composed of a Central processing unit (CPU) and a variety of hardware and software components, which makes it possible to solve most of the difficult tasks through the combination of functions and components. And as one type of special embedded system, CPLDs (Complex Programmable Logic Devices) (or occasionally referred to as EPLDs, Enhanced-PLDs), is one of the important elements that help the system to run normally. And LC4256ZC-45M132C series is one commonly-used CPLD products.

LC4256ZC-45M132C series is a low-power, cost-effective and with powerful features of the Flash-based CPLD product. It features a robust architecture of 42 macrocells, and a Flip-Flop Macrocell. Specifically, the LC4256ZC-45M132C series is a 5V device that supports up to 1152 macrocells, and the LC4256ZC-45M132C series provides 4192 Flip-Flop Macrocells, 8kbits of RAM, 8192 bits of I/O, and has full support for In-System and in-Circuit programming. Moreover, the major components are built in, meaning that it doesn\'t require any external components. The LC4256ZC-45M132C series works in three voltage levels of 2.5V, 3.3V and 5V, so that it can meet various operation requirements.

The working principle of LC4256ZC-45M132C series CPLD is quite straightforward. When it encounters an incoming signal, the CPLD will transfers it through its powerful structure and analyze the input, like a logic O-gate, which received up to three input signals. Once all of the input conditions are met, the CPLD will send out a corresponding output signal. LC4256ZC-45M132C series CPLD can create even more complicated designs by combining multiple input and output functions. As one of the most important characteristic of this series CPLD, the programming capability makes it much simpler to implement initial design or scheme by users. LC4256ZC-45M132C series CPLD is mainly used for functions that patterns are regularly repeating. Thus its application field could be extended to:

• Sending control signal for communication systems
• Transforming data for digital signal processing
• Triggering control signal for memory chips
• Controlling device circuit in audio and visual products
• Data processing in Consumer electronics, such as game console, set-top box, GPRS terminal, etc.
• Signal recognition and recognition circuit in Industrial Controller
• PC board peripheral circuit control in computer
• Battery Protection

To conclude, LC4256ZC-45M132C series CPLD is a cost-effective, power-saving and good-performance device, including 42 macrocells and Flip-Flop Macrocell. As known that it works in three voltage levels of 2.5V, 3.3V and 5V, and provides 8kbits of RAM and 8192 bits of I/O. In addition, programming capability is also one of major advantages of it. The possible application fields of it is quite versatile, from products such as GPRS terminal, game console, and set-top box, to Industrial Controller, PC peripheral circuit and Battery Protection. All in all, LC4256ZC-45M132C series CPLD is an indispensable embedded system that can facilitate and accelerate embedded system development.
