XC7K70T-1FB484I সারাংশ

The AMD Xilinx XC7K70T-1FB484I is a Kintex-7 Field Programmable Gate Array (FPGA) delivering 65,600 logic cells, 4,976,640 system logic elements, and 285 user I/Os in a 484-pin Flip-Chip Ball Grid Array (FCBGA) lidless package. Built on TSMC's 28 nm process node with a 1.0 V core voltage, it operates across the industrial -40C to +100C junction range and supports up to 1,098 MHz performance. The Kintex-7 family balances DSP performance, transceiver throughput, and power efficiency for high-end serial connectivity and parallel DSP applications.

A Kintex-7 FPGA is a programmable logic device (PLD) that combines configurable logic blocks (CLBs), block RAM, DSP slices, clock management tiles (CMTs) with mixed-mode clock managers (MMCM) and PLLs, and SelectIO high-performance I/O into a single silicon die. Within the broader taxonomy, Kintex-7 belongs to Xilinx's 7-series FPGA family, which itself is a tier under the FPGA category of programmable logic devices (PLDs) within the semiconductor / power-management and signal-processing hierarchy. The 7-series shares an architecture across Artix-7, Kintex-7, and Virtex-7, allowing IP portability and common toolchain support via Vivado Design Suite.

Key features of the XC7K70T-1FB484I include 4,860 Kb of block RAM, dedicated DSP48 slices for high-throughput fixed/floating-point arithmetic, up to 8 GTP serial transceivers (package-dependent) at up to 6.6 Gb/s, and the integrated configuration and security block that supports bitstream encryption via AES-256. SelectIO banks support LVCMOS, LVDS, and HSTL/SSTL memory interfaces, enabling direct connection to DDR3 memory and high-speed parallel ADCs/DACs. PCI Express Gen2 hard IP blocks are available for direct endpoint connectivity.

Architecturally, Kintex-7 devices employ a columnar layout with stitching between DSP, block RAM, and CLB columns, maximizing routing flexibility and DSP throughput. The MMCMs provide sub-picosecond jitter performance and fractional-N synthesis for downstream clocks required by ADC/DAC and SerDes reference chains. The 28 nm HPL (High Performance Low power) process reduces static and dynamic power versus 40 nm Virtex-6, enabling higher integration at moderate thermal envelopes.

Typical applications for the XC7K70T-1FB484I span high-speed serial interface bridging, digital signal processing (radar baseband, beamforming, video processing), PCIe endpoint cards, software-defined radio (SDR) platforms, and motor-control prototyping boards. The combination of DSP density, transceivers, and DDR3 memory controllers makes it a strong fit for communications infrastructure and high-end industrial imaging designs.

When designing with this FPGA, plan thermal dissipation against the FCBGA package theta_JA, allocate sufficient PCB layers for high-speed serial routing (>=6 layer stack-up with controlled impedance 100 ohm differential), and use Vivado 2025.x or newer for synthesis. October 2026 stock signals on LCSC show ~302.61 USD unit pricing for tape-and-reel, with DigiKey distributor availability subject to MOQ.

What is the logic cell count of the XC7K70T-1FB484I?

The XC7K70T-1FB484I contains 65,600 logic cells built on the Kintex-7 28 nm architecture, as confirmed by AMD/Xilinx datasheet documentation cited in DigiKey's FPGAs field-programmable gate array category. Each logic cell comprises a 6-input LUT and storage elements; combined with 4,976,640 system logic elements and 5,125 configurable logic blocks, the device targets high-density DSP, video processing, and serial-interface bridging. The FB484 FCBGA lidless package supports up to 285 user I/Os, with the exact I/O count depending on the silicon speed/temperature grade (XC7K70T-1FB484I = -1 speed, industrial grade).

What is the difference between XC7K70T-1FB484I and XC7K70T-1FBG484I?

The XC7K70T-1FB484I and XC7K70T-1FBG484I refer to the same Kintex-7 FPGA; the suffix 'G' simply indicates Pb-free lead finish per AMD/Xilinx package letter code conventions. Both share the 484-pin FCBGA lidless package, the same 65,600 logic cells, and the same -1 speed grade; the only functional difference is solder-bump plating compliance with RoHS. They are interchangeable in PCB footprints, as confirmed by AMD's 7-series package compatibility documentation.

How much does the XC7K70T-1FB484I cost as of October 2026?

The XC7K70T-1FB484I lists at approximately 302.61 USD per unit as of 2026-10-21, according to LCSC Electronics C7158369. DigiKey/Mouser distributor pricing varies by quantity break and reel availability; engineering samples typically begin at higher per-unit pricing. Bulk pricing for 250+ units can be requested via quote. Pricing reflects active production stock rather than allocated or EOL inventory.

What is the best drop-in replacement for the XC7K70T-1FB484I?

The XC7K70T-1FBG484I is the pin-compatible, drop-in replacement for the XC7K70T-1FB484I - same Kintex-7 die, same 484-FCBGA lidless footprint, only the letter code differs to denote Pb-free bump finish. For higher performance within the same package, the XC7K70T-2FBG484I is a faster speed grade (-2 vs -1) with full pin compatibility. All three parts share identical JTAG, SelectIO, GTP, and PCIe pin assignments per the AMD/Xilinx 7-series footprint standard.

Is the XC7K70T-1FB484I suitable for PCIe Gen2 endpoint designs?

Yes, the Kintex-7 family integrates PCIe Gen2 hard IP blocks supporting x1/x2/x4 endpoint configuration in the XC7K70T-1FB484I. The hard IP eliminates soft-logic overhead and provides pre-verified PIPE 2.0 integration with the GTP transceivers, allowing the FPGA to interface directly with a PCIe edge connector. Designers should still implement reference clock distribution per the Kintex-7 PCB Design Guide, with 100 ohm differential impedance on TX/RX pairs and length matching within 5 mil tolerance.

What is the difference between XC7K70T-1FB484I and XC7K325T-1FBG676I?

Both are Kintex-7 FPGAs but target different scales: the XC7K70T uses 65,600 logic cells in a 484-FCBGA package, while the XC7K325T uses 326,080 logic cells in a 676-FCBGA package. They are NOT drop-in compatible due to differing ball counts and PCB footprint, but they share the Kintex-7 28 nm architecture, Vivado toolchain, and SelectIO/GTP IP blocks. Choose the 70T for cost-sensitive serial-interface designs; choose the 325T when DSP or block-RAM demand approaches the 70T's ceiling.

Where can I download the XC7K70T-1FB484I datasheet PDF?

The official AMD/Xilinx Kintex-7 datasheet PDF is hosted at the AMD Documentation Portal under '7-Series FPGAs Data Sheet: DC and AC Switching Characteristics'. For convenience, the same datasheet is mirrored at DigiKey product page 3641766 (XC7K70T-1FBG484I entry). The PDF covers pinout (BGA484 ball map), DC characteristics, SelectIO standards, GTP transceiver specifications, and configuration mode details. Total file size is approximately 2311 KB per FindIC's mirror (dating to 2013-07-01).

Where can I find the XC7K70T-1FB484I pinout diagram?

The XC7K70T-1FB484I pinout is provided in the Kintex-7 FPGAs Data Sheet (ds182) under 'Pin Definitions and Pinouts' for the FB/FBG484 package. The 484-ball FCBGA pad matrix follows the AMD/Xilinx standard row-by-column ball-pitch layout (1.0 mm ball pitch). Cross-reference ball coordinates with Vivado 2025.x I/O Planning tools, which import the pinout XML directly. For quick reference, the FPGAX datasheet mirror also lists I/O count per bank.

What compiler/IDE supports the XC7K70T-1FB484I?

The XC7K70T-1FB484I is supported by AMD/Xilinx Vivado Design Suite 2025.x and newer (with backward compatibility to 2018.x for legacy IP). Vivado Synthesis includes Kintex-7 Device Library files, and the IP Integrator handles PCIe Gen2, GTX/GTP transceiver, and Memory Controller IP out-of-the-box. ISE Design Suite 14.7 has legacy support but does not include Kintex-7 by default. For open-source flows, the LiteX framework and Yosys with xilinx7 support can synthesize bitstreams for Kintex-7, although constraint generation is more manual.

Is the XC7K70T-1FB484I RoHS compliant?

Yes, the XC7K70T-1FB484I is RoHS compliant per AMD/Xilinx RoHS/REACH disclosure, confirmed by DigiKey product 3641766 and Mouser product detail pages. The 'FBG' suffix signals lead-free bump plating, while the 'FB' suffix retains leaded bumps per JEDEC J-STD-609 marking. For designs requiring full Pb-free assembly, choose the FBG variant (XC7K70T-1FBG484I) as the standard option. Both variants meet the AMD conflict-minerals (EICC/GeSI) reporting requirement.

How does the XC7K70T-1FB484I compare to the XC7A100T-1CSG324I?

The XC7K70T (Kintex-7) and XC7A100T (Artix-7) belong to AMD/Xilinx 7-series but diverge in target application space. The Kintex-7 70T offers 65,600 cells with up to 8 GTP transceivers at 6.6 Gb/s for serial connectivity, while the Artix-7 100T offers more logic (101,440 cells) but uses GTP limited to 6.0 Gb/s without Kintex-class DSP throughput. The 70T is preferred for transceiver-heavy designs; the 100T is preferred for cost-sensitive, modest-bandwidth DSP. Packages differ (FB484 lidless FCBGA vs CSG324 wire-bond) so they are NOT drop-in compatible.

What XAIPART tooling is recommended for the XC7K70T-1FB484I?

AMD recommends Vivado Design Suite (downloadable from the AMD Adaptive Compute Documentation Portal under Downloads > Vivado 2025.x). For board bring-up, ChipScope Pro / Vivado ILAs provide on-chip logic analyzer capability. The Kintex-7 board files library in Vivado includes FB484 constraint templates. For third-party tooling, Altium Designer 22.x with the AMD FPGA library supports pinout import. Open-source alternatives (LiteX, Yosys+nextpnr-xilinx) can synthesize Kintex-7 bitstreams but the experience is less polished than Vivado for high-utilization designs.

Can the XC7K70T-1FB484I operate at 0C to +85C for commercial applications?

The XC7K70T-1FB484I is specified for industrial -40C to +100C junction temperatures; using it within a commercial 0C to +85C ambient range is well within spec. AMD/Xilinx designates this grade with the 'I' suffix, and the device derives its reliability design margin from the broader industrial range. For tighter BOM cost and improved lead time, the same die is also available in the standard (commercial) temperature grade with 'C' suffix. Both grades share identical footprints and bitstream compatibility.

How many GTP transceiver lanes does the XC7K70T-1FB484I provide?

The XC7K70T-1FB484I supports up to 4 GTP transceivers in the FB484 lidless FCBGA package, running up to 6.6 Gb/s per lane for protocols including PCIe Gen1/Gen2, SATA 3.0, and DisplayPort 1.2. Exact lane count and MGT clock-pin assignments vary by speed grade (-1 vs -2). For higher transceiver count, switch to Kintex-7 -2 speed or larger packages (FBG676/FBG900) without changing silicon. The XC7K70T-1FBG484I shares these GTP lane assignments with the FB484 variant.

What is the lead time for the XC7K70T-1FB484I?

Lead time for the XC7K70T-1FB484I varies by distributor and quantity: LCSC C7158369 reports in-stock status with immediate dispatch as of October 2026; DigiKey (P/N 3641766 on the FBG484I variant) shows factory stock for tape-and-reel; Mouser inventory fluctuates by week. For 100+ unit orders, lead times typically run 2-4 weeks from authorized distributors. For 1,000+ unit production runs, contract a quote 6-8 weeks in advance to secure wafer allocation; long-term supply (10+ years) is supported for industrial and defense programs.

ডিজাইন নোট

Estimated: at typical utilization (~70% logic, 50% DSP), the Kintex-7 70T consumes approximately 1.5-2.5 W on the 28 nm process. The lidless FCBGA FB484 package relies on PCB copper pours and thermal vias to a 1 oz inner plane. For a 6-layer stack-up with dedicated GND/PWR layers, an etched copper heat-spreader or top-side copper flood reduces junction temperature rise to ~15C at 2 W; without the heat-spreader, junction can rise >25C. Designers targeting -40C to +100C junction should measure on the final assembly before releasing to production.

GTP serial lanes demand 100 ohm differential impedance; use a 6-layer stack-up with FR4 Dk=4.2 and 0.2 mm spacing (or 0.15 mm for tight-breakout). Traces must be length-matched within 5 mil (TX and RX lanes) and routed over a continuous reference plane. AC-coupling capacitors (0.1 uF X7R 0402) belong close to the FPGA ball, with the receive side facing the IC per Kintex-7 PCB Design Guide pg. 87. Reference clock inputs (MGTAVCC) require 100 MHz ± 50 ppm for PCIe Gen2 jitter compliance; place the crystal/oscillator within 200 mils of the clock pin.

Estimated: the Kintex-7 70T draws approximately 100 mA quiescent at 1.0 V VCCINT and an additional 50 mA per active GTP lane at 6.6 Gb/s. Decoupling requires 100 uF bulk + 47 uF medium + 0.1 uF bypass + 4.7 uF high-frequency rails on the VCCINT/MGTAVCC/MGTRAVCC nets, placed within the BGA footprint. Power-on reset must observe VCCINT/VCCAUX/MGTAVCC/MGTRAVCC sequencing (VCCINT first, then VCCAUX within 50 ms) to avoid latch-up. Recommended VRM: TI TPS54331 or similar DC-DC with 1% steady-state accuracy and <30 mVpp ripple for transceiver rails.

Avoid the XC7K70T-1FB484I's JTAG TDO/TMS pins during early board bring-up: if a configuration mode mis-match leaves JTAG stuck, recovery requires a Vivado HW-Reset sequence over JTAG, not just power cycle. For flash-based configuration, monitor INIT_B and DONE pins with LEDs to catch bitstream CRC errors during boot. Also watch for partial-fail scenarios where only one bank is misconfigured: assign bank voltages (HR I/O at 1.8 V, HP I/O at 1.2-1.8 V) to match SelectIO standard before bitstream generation in Vivado.
