XC7A100T-2FGG484C vs XC7A200T-2FBG484C: Artix-7 FPGA Comparison

ElecSuppliers Part Number ComparisonAug 17, 2026

The XC7A100T-2FGG484C and XC7A200T-2FBG484C are two high-density AMD Xilinx Artix-7 FPGAs designed for applications that need programmable logic, DSP resources, embedded memory, and high-speed I/O.

Both devices use the -2 speed grade and commercial temperature grade, but they are different device sizes. The XC7A100T provides 101,440 logic cells, while the XC7A200T increases the capacity to 215,360 logic cells. The package design also differs: the XC7A100T uses FGG484, while the XC7A200T uses FBG484. AMD/Xilinx package documentation identifies these 484-ball package options as compatible for migration within the Artix-7 family.

XC7A100T-2FGG484C Overview

The XC7A100T-2FGG484C is an Artix-7 FPGA with 101,440 logic cells and 285 user I/O connections in the FGG484 package.

It includes approximately 4.97 Mbits of total RAM, 240 DSP slices, and four GTP transceivers. The device operates with a 1.0 V nominal core supply and supports a 0.95 V to 1.05 V VCCINT range. Distributor specifications list a commercial junction-temperature range of 0°C to +85°C.

The device is suitable for designs that need a relatively large FPGA while maintaining a compact 23 mm × 23 mm package.

XC7A200T-2FBG484C Overview

The XC7A200T-2FBG484C is a larger Artix-7 FPGA using the FBG484 package.

It provides 215,360 logic cells, more than twice the logic capacity of the XC7A100T. It also provides 285 user I/Os, approximately 13.46 Mbits of total RAM, 740 DSP slices, and four high-speed transceivers. Distributor specifications list the same 0.95 V to 1.05 V supply range and 0°C to +85°C operating temperature range for this commercial-grade part.

The XC7A200T is therefore intended for substantially larger designs that require more logic and signal-processing resources.

XC7A100T-2FGG484C vs XC7A200T-2FBG484C Specifications

The most significant difference is FPGA capacity. The XC7A200T has more than twice the logic-cell count and substantially more DSP and block RAM resources than the XC7A100T.

XC7A100T vs XC7A200T Logic Capacity

The biggest reason to choose the XC7A200T-2FBG484C is its additional programmable logic.

The XC7A100T contains 101,440 logic cells, while the XC7A200T contains 215,360. This gives the XC7A200T considerably more room for large RTL designs, parallel processing, embedded processors, communication logic, and complex control functions.

The additional resources can also reduce the risk of running out of FPGA capacity as a design evolves.

For a design that comfortably fits inside the XC7A100T, however, moving to the XC7A200T may not provide a practical benefit unless additional resources are needed.

DSP and Memory Differences

The XC7A200T also has a major advantage in DSP resources.

The XC7A100T provides 240 DSP slices, while the XC7A200T provides 740. This difference can be important for applications involving filtering, FFT processing, image processing, motor control, software-defined radio, and other mathematically intensive workloads.

Memory capacity also increases substantially.

The XC7A100T provides about 4.97 Mbits of total RAM, while the XC7A200T provides about 13.46 Mbits. This additional on-chip memory can be useful for buffering, FIFOs, lookup tables, image data, and intermediate processing results.

Do XC7A100T-2FGG484C and XC7A200T-2FBG484C Have the Same I/O?

Both devices provide 285 user I/Os in these 484-ball package configurations.

This is an important point because the XC7A200T does not increase the available user-I/O count simply because it has a larger FPGA fabric.

The main upgrade is therefore internal capacity rather than a higher number of external signals.

For a system where the existing design is limited by logic, DSP, or memory resources, the XC7A200T can provide a significant improvement.

For a system limited mainly by I/O count, moving from XC7A100T to XC7A200T may not solve the problem.

FGG484 vs FBG484 Package

The package suffixes are different:

XC7A100T-2FGG484C → FGG484

XC7A200T-2FBG484C → FBG484

Both are 484-ball packages with a 23 mm × 23 mm package size. AMD/Xilinx package documentation lists FGG484 and FBG484 as compatible package options for the relevant Artix-7 devices, supporting migration between the two package types within the family.

However, package compatibility should not be interpreted as meaning that the two devices are automatically interchangeable in every design.

The exact pin assignment, power connections, I/O standards, configuration interface, and PCB implementation should still be checked before migration.

Can XC7A200T-2FBG484C Replace XC7A100T-2FGG484C?

The XC7A200T-2FBG484C can be an attractive upgrade path when an existing XC7A100T design requires more FPGA resources.

The larger device provides substantially more logic cells, DSP slices, and internal memory while maintaining the same 484-ball package class and 285-user-I/O count.

This makes the pair particularly interesting for designs that may outgrow the XC7A100T.

However, migration should be performed using the appropriate device and package settings in Vivado. The design should be rebuilt and checked for timing, power, pin assignments, and implementation constraints before production.

Can XC7A100T-2FGG484C Replace XC7A200T-2FBG484C?

The opposite substitution is more restrictive.

Because the XC7A100T has less than half the logic-cell capacity of the XC7A200T, a design developed specifically for the XC7A200T may not fit into the XC7A100T.

The smaller device also has fewer DSP slices and substantially less internal RAM.

Therefore, the XC7A100T should not be treated as a general replacement for the XC7A200T. It can only be considered if the actual design resource utilization fits within the smaller device.

Which Artix-7 FPGA Should You Choose?

The XC7A100T-2FGG484C is a better fit when the design needs 100K-class logic capacity and the available resources are sufficient.

The XC7A200T-2FBG484C is better suited to larger designs that require significantly more logic, DSP processing, and embedded memory.

Both use the -2 speed grade, so this comparison is primarily about FPGA capacity and package migration, rather than a difference in speed grade.

For an existing XC7A100T design, the XC7A200T can be considered when additional resources are needed. For an existing XC7A200T design, moving down to XC7A100T requires a detailed resource-utilization review.

XC7A100T-2FGG484C vs XC7A200T-2FBG484C: Which Is Better?

Neither device is universally better.

The XC7A100T-2FGG484C offers a balance of logic capacity, DSP resources, memory, I/O, and package size for medium-sized Artix-7 designs.

The XC7A200T-2FBG484C provides substantially more internal resources while retaining 285 user I/Os and a 484-ball, 23 mm × 23 mm package.

For designs that need additional FPGA capacity, the XC7A200T is the stronger option. For designs that already fit comfortably in the XC7A100T, the smaller device may be the more practical choice.

The most important factor is therefore not simply the number in the part name, but the actual logic, DSP, memory, I/O, timing, and power requirements of the application.
