Embedded systems (CPLDs) have become increasingly popular in recent years due to their versatile and reliable features. The EPM7128AETC100-5N is a Complex Programmable Logic Device (CPLD) that offers a high level of programmability and flexibility. This CPLD is suitable for a wide range of applications, ranging from medical and industrial uses to consumer electronics and networking systems.

The EPM7128AETC100-5N CPLD consists of up to 81 macrocells, each of which can be individually configured as a logic block or set of logic blocks. The 81 macrocells can be further grouped into two blocks of 16 (or 32) macrocells, 8 macrocells and 11 macrocells. Each macrocell consists of four flip-flops, two multiplexers and two configurable logic blocks (CLBs), with a total of 800 combinatorial terms. The CPLD also contains 4 dedicated input/output blocks (I/Os) and optional non-volatile memory blocks that can store up to 8 kB of data.

The EPM7128AETC100-5N is capable of implementing many types of functions, including timing, data processing, arithmetic and logic operations, system control, address encoding, interface conversion and bus arbitration. In addition, it can also be used to create complex designs using Sequential Logic, Combinatorial Logic and State Machines.

In terms of application fields, the EPM7128AETC100-5N CPLD can be used in a wide range of applications, including medical systems, industrial automation systems, consumer electronics and communications. By offering high performance and flexibility, it is suitable for applications where a large number of functions need to be implemented in a low-cost, low-power and space-efficient device.

As for the working principle of an EPM7128AETC100-5N CPLD, data is loaded into the device from external memory over a serial interface. The data is then processed by the CPLD’s control unit and stored in the device’s internal RAM. Once the data is stored, it can then be executed by the device’s logic cells to create the desired logic functions.

The device produces its output signals by decoding the logic functions stored in its RAM and translating them into logic values. The output signals can then be used as inputs to other devices or systems.

The EPM7128AETC100-5N also features built-in in-system programming (ISP) and debugging features. This allows the device to be re-programmed or debugged without having to remove it from its application. Additionally, the device includes an on-chip serial EEPROM memory that can be used to store configuration information, restoring the device to its original state after a system reset.

The EPM7128AETC100-5N CPLD is an incredibly versatile and powerful device that offers a wide range of features and flexibility for various design applications. With its high performance, flexibility, and low cost, it is an ideal choice for many embedded system designs.
