Embedded systems have revolutionized the way we do computing, by allowing us to define our applications\' architecture in software rather than hardware. Programmable logic devices (PLDs) are popular components for the construction of specialized hardware and software systems within the embedded system domain. Among those PLDs, the ATF20V8B-15SC is one of the most commonly used. In this article, we will discuss the application field and working principle of this device.

Application Field

The ATF20V8B-15SC is a field-programmable gate array (FPGA) that is typically used in the design of digital control systems. Examples of such applications include digital PLCs, CNC units, and industrial robotics. The FPGA is programmed through VHDL (verilog) to create digital logic circuits, finite state machines, and embedded systems, based on the desired application.

The ATF20V8B-15SC is also commonly used in the design of embedded systems, such as micro-controllers, embedded processors, and digital signal processors. It is typically used in designs that require high performance, low power consumption, and small size.

Working Principle

The ATF20V8B-15SC contains two levels of logic based on CMOS technology. The first level consists of a set of eight non-reconfigurable logic levels, or "slices". Each slice contains two 4-input look-up tables (LUTs), which are used to implement a logic function from a given set of inputs and an output. The slices are also connected to a register, which further enhances their flexibility as logic elements.

The second level of the ATF20V8B-15SC contains a set of 16 general-purpose configurable flip-flops, which are used to store the data stream input to the device. The flip-flops are used to implement a variety of logical operations and can be configured to generate signals at any time when the logical expressions set by their inputs are true. They can also be used to generate arbitrary timing and timing jitters.

In order to configure the ATF20V8B-15SC, the programmer must first generate a program file, which is written in either VHDL or Verilog. This program file is then sent to the device and parsed by the on-board logic in order to generate the desired logic level. Once the desired logic is generated, the device is ready to be used in the application.

The ATF20V8B-15SC is an FPGA that provides an efficient and cost-effective way of implementing complex digital systems. With its two levels of logic, it can be used to implement a variety of digital control systems, embedded systems, and digital signal processors.

In summary, the ATF20V8B-15SC is a FPGA used in the design of embedded systems, digital control systems, and digital signal processors. By using VHDL or Verilog, the device can be programmed to generate a variety of digital logic operations, and its two levels of logic make it ideal for a wide range of applications.
