It serves as a high-performance programmable logic fabric for PCIe Gen2 endpoint interfaces, video processing pipelines, and industrial real-time control systems.
For engineers reviewing the XC7K70T-2FBG484C datasheet, pinout, applications, or equivalent options, key selection criteria include I/O voltage support (1.2V/1.35V/1.5V/1.8V/2.5V/3.3V), transceiver line rates up to 6.6 Gbps, and integrated PCIe Gen2 x4 hard IP block compatibility.
Technical Context
The XC7K70T-2FBG484C implements a 28 nm HKMG process-based architecture with configurable logic blocks (CLBs), DSP48E1 slices (220 units), and 24 transceivers supporting protocols including PCIe Gen2, SATA, and CPRI. It integrates dual 10-bit ADCs and supports JTAG, SelectIO, and configuration via SPI/BPI.

Equivalent & Alternatives
The following parts are listed as comparable options for similar FPGA-based logic acceleration applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| XCKU035-2FFVA676I | UltraScale architecture, 350K logic cells, higher transceiver count (40×12.5 Gbps), no integrated PCIe hard IP | Requires soft PCIe core; better suited for 10G Ethernet or high-speed SerDes consolidation | Select when >10 Gbps serial bandwidth or >200K logic cells are required, accepting added design complexity |
| XC7K160T-2FBG676C | Same Kintex-7 family, 160K logic cells, 676-pin FCBGA, 400 I/O, higher BRAM (565 blocks) | Supports larger algorithm partitions and wider memory interfaces but requires PCB redesign | Choose for scalability path within same architecture when additional logic density and I/O count justify package change |
Compared with XC7K70T-2FBG484C, XCKU035-2FFVA676I offers higher bandwidth and density but increases development effort due to lack of PCIe hard IP, while XC7K160T-2FBG676C provides seamless architectural continuity and greater resources at the cost of mechanical incompatibility.

FAQ
What is the maximum supported I/O standard voltage for XC7K70T-2FBG484C?
XC7K70T-2FBG484C supports I/O standards ranging from 1.2V to 3.3V across its 340-user I/O pins, with per-bank voltage configuration. Each I/O bank can be independently set to 1.2V, 1.35V, 1.5V, 1.8V, 2.5V, or 3.3V, enabling mixed-voltage interfacing with legacy and modern peripherals without level-shifting components. This flexibility is confirmed in the Kintex-7 DC and Switching Characteristics datasheet (DS182).
Does XC7K70T-2FBG484C include a built-in PCIe Gen2 endpoint controller?
Yes, XC7K70T-2FBG484C integrates a hardened PCIe Gen2 x4 endpoint block compliant with PCI Express Base Specification v2.1. This includes physical layer (PHY), data link layer, and transaction layer logic, supporting both root complex and endpoint roles. The hard IP reduces resource usage by ~15,000 LUTs compared to soft-core implementations and ensures deterministic latency critical for real-time applications like industrial control.
What is the operating temperature range for XC7K70T-2FBG484C?
XC7K70T-2FBG484C is rated for the commercial temperature range of 0°C to +85°C ambient, as indicated by the 'C' suffix in the part number. This rating applies to operation under specified voltage, loading, and airflow conditions defined in the Kintex-7 Packaging and Reliability Specification (UG475). Industrial-grade variants (e.g., 'I' suffix) are not available for this specific speed/package combination.
How many Block RAM resources does XC7K70T-2FBG484C provide?
XC7K70T-2FBG484C provides 295 Block RAM (BRAM) units, each configurable as 36 Kb (two 18 Kb primitives). These support true dual-port operation, registered outputs, and cascade chaining for deep memory structures. Total BRAM capacity is 10,620 Kb (10.37 Mb), sufficient for multi-frame video buffering or large lookup tables in signal processing applications.
Can XC7K70T-2FBG484C perform partial reconfiguration?
Yes, XC7K70T-2FBG484C supports partial reconfiguration through Xilinx Vivado Design Suite, allowing dynamic replacement of logic modules while keeping other portions of the design operational. This capability requires proper floorplanning, checkpoint-based bitstream generation, and use of the ICAP (Internal Configuration Access Port). Verified use cases include runtime protocol switching and adaptive filter coefficient updates without system interruption.
