Embedded system applications using programmable logic devices (PLDs) such as complex programmable logic devices (CPLDs) provide designers with the ability to rapidly develop sophisticated applications with the flexibility to modify, upgrade and extend the application ability to meet their specific needs. These CPLDs are used in applications requiring a mix of logic and memory elements to solve complex logic problems. The EPM7160SQC160-7 is one such CPLD and widely used in applications such as control systems, video/imaging control, industrial automation and embedded design.

A CPLD differs from an Application Specific Integrated Circuit (ASIC) in that it is programmable. Its size and features are determined by the designer. In the case of the EPM7160SQC160-7 the device is a Complex Programmable Logic Device (CPLD) designed with 16 macrocells. This device is ideal for applications where space is at a premium and offers greater flexibility than an ASIC or Microcontroller.

Understanding the working principle of the EPM7160SQC160-7 is an important part of any design process. The device is designed to accept a series of inputs and generate a single output based on the program\'s logic. TheEPM7160SQC160-7 utilizes macrocells to implement the program logic. Each macrocell contains two flip-flops with associated logic and programming capability. The macrocells are connected by programmable internal routing resources, which allow the designer to customize the interconnections between macrocells.

The EPM7160SQC160-7 device is a low power CPLD and is composed of four logical blocks: the programmable array logic (PAL), the control logic unit (CLU), the programmable timer/counter (PCU) and the input/output block. The PAL, or array logic, is responsible for logic operations such as Boolean addition, ANDing, ORing, and XORing. The CLUblock provides clock control and synchronization between the PAL, PCU and the input/output blocks. The PCU, or programmable counter, allows for a variety of functions such as pulse shaping and counting. The input/output block provides the interface with the external world, providing data and I/O control.

The EPM7160SQC160-7 provides designers with a low cost, low-power solution for applications requiring a mix of logic and memory elements to solve complex logic problems. The device allows designers to easily configure the logic of their applications with the help of the ready-made macrocell blocks and programmable routing resources. The integrated timer/counter of the device also allows for more advanced timing and counting functions. The device is widely used in applications such as industrial automation, control systems, video/imaging control, and embedded design.
