Embedded - CPLDs (Complex Programmable Logic Devices) are programmable logic devices (PLDs) that can be used in a wide variety of application fields. The EPM1270F256C4N, from Altera Corporation, is an example of a CPLD which is designed for use in embedded systems such as automotive, avionics, and consumer electronics.

The EPM1270F256C4N is a low-cost, low-power device, with a maximum power consumption of only 0.425W. The device has 256 macrocells, 250 input and output pins, occupied area of 17.8mm x 17.8mm, and comes with an on-board 1V to 4.6V voltage regulator. The device also includes two high-speed on-chip universal high-speed clock multiplier (UHCM) module, two programmable clock buffers and two high-speed transceivers. This makes it suitable for use in a wide range of applications such as industrial, communication, and consumer applications.

The EPM1270F256C4N is the first device in a series of three CPLDs from Altera, the other two being the EPM1270F512 and the EPM1270F1024, both of which offer higher performance and a larger number of pins than the EPM1270F256C4N.

The working principle of the EPM1270F256C4N is based on the use of an array of logic cells. Each cell has four input ports and one output port, which are then connected to the programmable interconnects. These interconnects are programmed using the unique programming language of the device (TPL). This programming language allows the designer to create customized logic along with pre-defined logic within the array of logic cells. The gates then become active when their input ports are set.

The EPM1270F256C4N is suitable for implementation of data acquisition, communications, control systems, and embedded processor applications. The device also includes many features such as a low-power sleep mode, high-density routing resources, up to 16 device I/O bank means, on-chip voltage detection, capacity for up to 4kb of configuration data, and dedicated input pins for readback mode.

The EPM1270F256C4N is a versatile device that can be used in a range of automotive, avionics, consumer electronics, and industrial applications. The device can be used in applications such as motor control, numerical control, smart power, and digital power conversion. Additionally, the device can be used to implement complex algorithms, high speed communications systems, and data acquisition units with the help of its unique programming language.
