Complex Programmable Logic Devices (CPLDs) are embedded digital devices that provide a cost effective solution for the control of combinatorial logic. They consist of a combination of configurable logic blocks (CLBs) which can be interconnected to perform a wide range of logic functions. The EPM7128SLC84-6 is a CPLD device. It is a high performance, in-system programmable, enhanced-matrix CPLD family with multiple outputs and enhanced I/O capability.

The device includes an array of programmable rows and columns which allow for more dense designs with more flexible routing options. The device has an asynchronous reset, programmable I/O filters, integrates synchronization logic and supports I2C, JTAG, and SPI bus operations. It is available in a range of packages from 40 flat-lead PLCC to 484 pin TQFP packages.

The EPM7128SLC84-6 is used for a variety of applications including embedded system control and communications, medical, industrial, automotive, and consumer applications. It is designed to simplify the design process by providing an easy way to program the logic functions needed in these designs. The device features two 16-bit shift registers and an address decoder, allowing it to be used in bus-oriented architectures. It has an extensive set of I/Os, with up to 32 clock sources and 32 microprocessor interrupts, and is capable of implementing complex state machines with built-in state machine controllers.

The working principle of the EPM7128SLC84-6 is to program its “macrocells” with input and output data. The macrocells then take that information and perform operations on it, such as logic operations, memory operations, and other complex operations. The device also includes registers, which are places to store data when the device is turned off. When the device is powered on, the registers are read and the output data is changed if necessary.

The device also includes an on-chip programmable logic array (PLA), which is a network of logic gates that can be used to create larger logic functions. The PLA is programmed by the designer with logic equations that define the behavior of the logic function they are seeking to create. The fields of logic equations are then read and stored in a configuration memory such as EEPROM or Flash memory.

The device also features a number of I/O options, such as pullup resistors, I2C and SPI bus interfaces, and a programmable edge detector, allowing it to be used in a wide variety of applications. With the edge detector, the device can detect and respond to rising, falling, or both edges of a signal, allowing it to be used to detect changes in data. It also includes an on-chip oscillator, allowing the device to time itself and provide a clock signal to its connected devices.

The EPM7128SLC84-6 is a powerful CPLD device that provides designers with a fast, efficient, and cost-effective solution for the control of combinatorial logic. It is designed to simplify the design process and offer a cost-effective way to create complex logic functions in a wide variety of applications. The device features an array of programmable rows and columns, multiple I/O options, and an on-chip oscillator, allowing it to be used in a variety of applications.
