What is Xilinx XA3SD3400A-4CSG484I ?

Field Programmable Gate Arrays (FPGAs) are used to reprogram the components of a circuit board. These gate arrays function via semiconductor devices that are based on Configurable Logic Blocks (CLBs). This would, in turn, be used to establish the connection to programmable interconnects.

The Xilinx XA3SD3400A-4CSG484I FPGA is a type of circuit board part from the stable of Xilinx (AMD). It is an automotive Integrated Circuit (IC) designed for use with automotive electronic devices.

Like other Field Programmable Gate Arrays (FPGAs), the Xilinx XA3SD3400A-4CSG484I can be reprogrammed or remodeled to fit into the desired functionality of an electronic device after its manufacturing.

Category of the Xilinx XA3SD3400A-4CSG484I FPGA

The Xilinx XA3SD3400A-4CSG484I is an Integrated Circuit (IC) with an embeddable design. This allows for easy installation or integration into any automotive electronic application.

Operating Temperature

The operating temperature of a Field Programmable Gate Array (FPGA) has to do with the minimum and maximum temperature for which the IC can operate.

The Xilinx XA3SD3400A-4CSG484I, being a part of the Xilinx Spartan 3A family, takes a leaf from the extended-temperature grade of FPGAs in that family. Its temperature rating is (~40˚C – 100˚C). This way, the components inside the Integrated Circuit (IC) wouldn’t underperform due to limited temperature or be exposed to over-performance because of excess temperature.

Number of Gates

The gates refer to the programmable gates used for enabling complex digital computations in a Field Programmable Gate Array (FPGA).

The Xilinx XA3SD3400A-4CSG484I has one of the highest numbers of gates with an estimation of 340,000. Ideally, FPGAs under the Xilinx Spartan 3A family have gates between 50,000 and 1.5 million.

Voltage Supply

The voltage of the Xilinx XA3SD3400A-4CSG484I is also regulated. This goes a long way to prevent the Integrated Circuit (IC) from either disrupting the entire functions of the board components or causing malfunctions.

The rated voltage supply is between 1.14 volts and 1.26 volts. Of course, you and the engineer can test the IC to be sure the power supply doesn’t fall below or go above this before deploying the semiconductor.

Logic Cells/Elements

While there are no single elements or components for a Field Programmable Gate Array (FPGA); some cannot be disposed of. One of such is the logic cells or elements. These elements comprise a large number of flip-flops and can double as a complete block of memory.

The logic elements/cells on the Xilinx XA3SD3400A-4CSG484I are significantly higher with an estimate of 53,712.


The Input and Output (I/O) of the Xilinx XA3SD3400A-4CSG484I is 309. Generally, the I/O of a Field Programmable Gate Array (FPGA) are dedicated processors that facilitate self-executing instructions in the Integrated Circuit (IC).

The Xilinx XA3SD3400A-4CSG484I’s I/O is significantly higher than some of the other FPGAs from the Xilinx Spartan 3A family. Xilinx recommends that the ideal range for the I/O in the Integrated Circuits (ICs) should not be above 487 I/O pins.

Mounting Type

The Xilinx XA3SD3400A-4CSG484I uses the Surface Mount Technology (SMT) for placing the components on the Integrated Circuit (IC). The SMT design is adjudged to be one of the best, especially when simplicity is considered.

Package & Case

The Xilinx XA3SD3400A-4CSG484I uses the “Tray” package. According to Digi-Key, the Tray FPGA package is a JEDEC matrix standard tray that measures 12.7 by 5.35. It also allows for the vertical passage of air, as enabled by the integration of slots in the tray.

The JEDEC tray can be manufactured with both aluminum and plastic, but plastic is more common.

The Integrated Circuit (IC) uses the 484-FBGA case. This type of case is categorized under the Ball Grid Array (BGA) Integrated Circuit (IC) package type. Under the Ball Grid Array (BGA), the most popular are:

  • Tape-ball Grid Array (TBGA)
  • Plastic-ball Grid Array (PBGA)
