How mcuh Xilinx XC3S50A-4VQG100I FPGA

Spartan-3A family consists of devices like XC3S200A, XC3S400A, XC3S700A, and XC3S1400A. XC3S50A-4VQG100I is one of the important family members of Spartan-3A FPGA family. It is an industrial use only device which comes up with extremely high performance. The XC3S50A-4VQG100I device is equipped with 100 pins and comes with Very Thin Quad Flat Pack also known as the VQFP. These devices are designed with -4 standard performance speed grade. As these are industrial only devices, so these can tolerate a wide range of extreme temperatures ranging from -40°C to 100°C. The XC3S50A-4VQG100I is equipped with 100 leads with maximum I/O of 68 and Lead pitch of 0.5 mm. The body area of XC3S50A-4VQG100I devices is 14 x 14 mm with maximum height up to 1.20 mm. Presence of Hierarchical memory architecture also known as SelectRAM™ is one of the prominent features of these devices. SelectRAM™ is a fast block RAM having speed of 576 Kbits. The XC3S50A-4VQG100I devices help in reduction of system power owing to presence of multiple voltage and multiple standard interface pins. These devices are also come up with QUIETIO attribute, which helps in reducing switching noise. The XC3S50A-4VQG100I devices are capable of transferring more than 640 Mb/s data rate as these are equipped with DDR RAM supported up to 400 Mb/s. These devices are also equipped with abundant and modifiable logic resources.  XC3S50A-4VQG100I devices have one column of block RAM. The block RAM contains a dedicated multiplier. The Digital Clock Meter in in these devices is positioned at the top. The Spartan-3A family exhibit rich routing network.

XC3S50A-4VQG100I Properties:

Xilinx FPGA

XC3S50A-4VQG100I devices contain Fine pitch Ball Grid Array also known as FBGA Array. These devices are equipped with 50K system gates with 1,584 equivalent logic cells. The XC3S50A-4VQG100I devices consist of programmable logic array of 16 rows and 12 columns with 176 CLBs (one CLB is equal to 4 slices thus making 704 total slices). XC3S50A-4VQG100I devices consist of 11K distributed RAM bits with 54K bits of blocked RAM. This family have three dedicated multipliers and comes with design containing 2 Digital Clock Managers. The two Digital Clock Managers are mounted on the top. User I/O pairs 0f 108 and 50 differential I/O pairs are also present in XC3S50A-4VQG100I. This family of Spartan-3A FPGA contains 144 Pins and comes up with Very Thin Quad Flat Pack. These devices can operate really well in diverse temperature range of -40°C to 100°C

Quiescent Current Conditions:

The XC3S50A-4VQG100I comes up with Quiescent VCCINT supply current of 20 mA, Quiescent VVCCO supply current of 2mA, and Quiescent VCCAUX supply current of 8 mA.

I/O Timings:

The clock to output timing settings of these devices ranges between 3.18 ns to 3.42 ns when Digital Clock meter is in use along with 12 mA device at fast slew rate. Similarly, output timing of XC3S50A-4VQG100I devices ranges between 4.59 ns to 5.02 ns with no Digital Clock Manager usage coupled with operation of 12 mA device at fast slew rate. Digital Clock Manager jitter is included in all explained output timings.
