LC4128C-5T128I Application Field And Working Principle

Embedded CPLDs (Complex Programmable Logic Devices) are widely utilized for system-on-a-chip (SOC) designs. LC4128C-5T128I is a single-chip design based on a Xilinx programmable logic technology which can realize embedded CPLD features. Various applications are possible in this technology, such as video and data processing, signal conditioning and signal synthesis applications.

The LC4128C-5T128I is a low-power, low cost, high-performance CPLD based on Xilinx XC4000XL architecture. It integrates an array of configurable logic blocks plus memory, distributed RAM, DSP capabilities and interconnects, making it a single-chip solution for embedded designs. Its programmable architecture enables designers to optimize the design with reduced complexity, speed, and power consumption.

The programmable logic portion of the LC4128C-5T128I consists of five devices, with each providing 128 logic elements (10-inputs and 86-outputs) and up to 32k bits of configurable RAM. The logic elements can be used to create logic functions using a variety of simple and advanced boolean operations, including XOR and XNOR operations. The RAM can be used to store data, program instructions, and control signals. The memory is organized as two 16K-word blocks, and can be accessed in two independent ways, using up to four 16K-block addressing modes.

The distributed RAM is used to store data and instructions in order to coordinate the operation of the LC4128C-5T128I\'s logic blocks. The RAM consists of 512K-bits of memory arranged into eight 8K-word blocks, with up to 16K-word addressing available on each block. The distributed RAM also includes a wake-up circuit that monitors user accesses and can be triggered to activate other logic blocks as needed. This feature helps reduce system latency.

In order to manage multiple devices, the LC4128C-5T128I offers comprehensive control bus (CMbus) commands for communication between devices, as well as with the system. The CMbus can also be used to manage multiple tasks within the same system. The data access command set provides access to a variety of data formats, including register read/write transactions and memory and I/O read/write transactions. The system support command set offers a variety of commands and features, such as reset, interval monitoring, and remote frame management.

The LC4128C-5T128I supports UltraScale™ capability, providing higher density, low power and scalar speed. With UltraScale™, multiple logic devices can be interconnected to perform complex dataflow operations. In addition to expanded logic functions, the devices also feature multi-threaded design options and system-level synchronous reset and asynchronous wake-up. Furthermore, the logic core has enhanced synchronous command capability, providing flexible control of logic functions.

The LC4128C-5T128I\'s fast I/Os range from 6ns to 20ns, allowing for a wide range of applications including data and application acceleration. The high speed transceivers provide additional bandwidth and high signal robustness for additional design flexibility. In addition, the high-performance embedded programmable logic also supports multi-media application such as video and audio applications.

The LC4128C-5T128I has a wide range of applications in embedded designs. It is ideal for applications such as embedded digital I/O, communication and signal processing, signal conditioning and signal synthesis, video and data processing and control systems. It is also suited for applications that require a high degree of flexibility and scalability due to its Highly Accessible Programmable Architecture (HAPA). The use of HAPA enables user-defined custom logic functions such as voltage or temperature sensing. The device is also well-suited for embedded graphics and 3D graphics applications.
