The Embedded - CPLDs (Complex Programmable Logic Devices) have increasingly become popular in various industries, due to their ease of use and adaptability. The LC4256B-75FTN256AI devices offer multiple power, functionality, and configuration options that make them self-suitable for a broad range of applications. In this article, we explore the device’s application field, as well as the working principle behind it.

The LC4256B-75FTN256AI is an embedded CPLD with 256 macrocells, 32 I/O pins and level shifters/bus pads. It is suitable for a range of uses, including industrial logic control, gate array logic, military applications, medical systems and instrumentation. The device is capable of reading and writing from/to SRAM, ROM, and EPROM, as well as performing logic operations on data. By combining simple logic elements, the device can be used for more complex tasks such as laying out and controlling multiple sources of power.

In terms of its application field, the LC4256B-75FTN256AI is used in digital systems such as core processing, programmable logic, and flash memory. It is also used in analog systems, allowing it to source and sink current levels as required. Through its integrated voltage translation technology, the device can cope with a wider range of voltage levels than traditional logic devices.

At its working principle, the LC4256B-75FTN256AI operates on a 3-state latch concept. When the device is idle, it will maintain its stored state until any of its inputs are changed. Once an input is received, the device will calculate the appropriate value for the output and store this value in an output latch. The output latch then drives the outputs according to the stored value.

The device is highly robust and is able to self-recover from failure events such as excessive current, fault isolation, and power glitches. This ensures superior reliability in critical applications. Additionally, the LC4256B-75FTN256AI supports multiple programmable configurations for flexible application in a variety of applications. These include register-based configuration, PROM memory-based configuration, and microprocessor-readable programming.

The abovementioned points essentially outline the application field and working principle of the LC4256B-75FTN256AI. The device is a powerful embedded CPLD, offering reliable and flexible applications in a wide range of industries and systems.
