Complex Programmable Logic Devices (CPLDs) are a type of general purpose Field-Programmable Logic Devices (FPLDs), where the difference between the two is that FPLDs have both a higher capacity and complexity than CPLDs. The EPM7256BTC100-7N is an example of a CPLD, which combines a low ball count, 40-pin package with low power, and high performance, enabling it to create special-purpose designs. This article will provide an overview of the application field and working principle of the EPM7256BTC100-7N.

Application Field of the EPM7256BTC100-7N

The EPM7256BTC100-7N is designed to efficiently take on designs requiring sophisticated logic and timing control. This CPLD is intended to help create designs with features such as solid state reliability, feature flexibility, and wide operating temperature ranges, making it suitable for industrial applications and electronic systems. The EPM7256BTC100-7N offers high system reliability since it can start up with a factory configuration and is re-programmable. Applications where the EPM7256BTC100-7N may be used include automotive body and chassis controls, industrial control systems, power control systems, and instrumentation systems.

Working Principle of the EPM7256BTC100-7N

The EPM7256BTC100-7N consists of 16 interconnected programmable logic cells that allow user to customise 32 I/O pins. The CPLD is able to support up to 7,196 useful product terms and up to 79 user-defined I/O functions. The device also comes with internal test registers that allow the user to check the correct functioning of the device.

The CPLD also features internal programmable voltage monitor (PVM) circuits, on-chip oscillator, power-on reset circuitry, and battery back-up options. The PVM circuits enable static voltage monitoring and programmable slow power-on loading for the I/O pins and the user-programmable registers. This makes the EPM7256BTC100-7N usable in low power applications.

The device can be programmed to perform various complex functions such as bit shifting, byte shifting, byte manipulation, addition/subtraction, multiplication, and logic functions such as AND, OR, NAND, NOR, and exclusive OR. Other features include on-chip parity support, programmable pulse-width modulation, on-chip counter, and programmable analog comparator.

Overall, the EPM7256BTC100-7N offers a wide range of features to assist in creating sophisticated electronic designs. With its high performance, low power, and flexibility, the device can be used in industrial applications, as well as automotive, power, and instrumentation systems.
