Introduction

The EPM9320RI208-20 is a complex programmable logic device (CPLD) designed for use in embedded applications. It is a small, low-power device with an areal density of only 3.2 mm2 and a power consumption of just 2.5 mW. It is used in applications requiring low-power, fast logic such as mobile phones, medical instruments and networking applications.The EPM9320RI208-20 has a balanced architecture that allows for high-speed component and system designs. It offers high performance programmable logic functionality, versatile input/output pins, variable clock divides and flexible status bits for maximum control of system performance.

Application Fields

The versatility of the EPM9320RI208-20 makes it suitable for a variety of applications. In communications, it can be used for Ethernet central processing units (CPUs), LAN controllers, base station controllers, Point of Sale (POS) terminals and so forth. In consumer electronics, it can be used in advanced TV set-top boxes and digital video recorders (DVRs). In medical electronics, it can be used in advanced pacemakers, implantable defibrillators, insulin pumps and home healthcare monitoring devices. In automotive electronics, it can be used in braking systems, automatic cruise control systems and advanced engine control systems. The EPM9320RI208-20 is ideal for data-handling applications. It can be used in data acquisition applications such as industrial control systems and digital signal processors (DSPs). It is also suitable for real-time systems such as access control, POS terminals and automated teller machines (ATMs). Furthermore, it can be used for audio and video applications such as multimedia systems, radio-frequency identification (RFID) systems and HDTV displays.

Working Principle

The EPM9320RI208-20 CPLD is based on an asynchronous, fully static architecture with a single-cycle instruction fetch/execute cycle. It consists of two main components: an array of programmable logic (PLA) and two-port RAM blocks. The programmable logic array handles the majority of the CPLD\'s logic, while the two-port RAM blocks provide the program and data storage. The EPM9320RI208-20 supports up to 20 inputs and outputs pins and uses a patented E-plug technology in order to securely reprogram and reconfigure devices without external power. The EPM9320RI208-20 has three primary modes of operation: stand-alone, in-system programming (ISP), and self-programming (SPI). In stand-alone mode, the CPLD can be programmed by directly connecting it to a programming device such as a universal programmer. In ISP mode, the EPM9320RI208-20 can be programmed and reprogrammed in-system after being placed on the device or system board. In SPI mode, the EPM9320RI208-20 can be programmed and reprogrammed by a master controller or microcontroller.

Conclusion

The EPM9320RI208-20 is an advanced CPLD designed for embedded applications. Its low-power consumption and high-performance make it suitable for a wide range of applications, from communications to consumer electronics and from medical electronics to automotive electronics. Its single-cycle instruction fetch/execute cycle makes it ideal for data-handling applications, while its E-plug technology allows direct programming and reprogramming of the device without external power.
