XC7A100T-2FT256I - 170 I/O Artix-7 FPGA | AMD
部品番号: XC7A100T-2FT256I ✓ 生産中XC7A100T-2FT256I 概要
An FPGA is a programmable semiconductor whose digital logic blocks, interconnections, and peripheral resources are configured after manufacture. Within the semiconductor hierarchy, the Artix-7 device belongs to the FPGA and CPLD family of programmable logic devices. Compared with a fixed-function ASIC, an FPGA allows design changes, parallel processing, and hardware acceleration without redesigning an integrated circuit.
The XC7A100T-2FT256I provides 170 user I/O in the verified distributor records, with the 256-FTBGA package providing the physical interconnect for those interfaces. The -2 speed grade is the central performance designation for this ordering code. Its Artix-7 architecture supports parallel datapath and control implementations where deterministic, configurable hardware is more useful than a sequential processor-only approach.
Typical uses include industrial automation, embedded instrumentation, test and measurement, embedded video, communications gateways, and digital signal-processing front ends. Parallel ADC data can be captured, filtered, transformed, and routed without transferring every sample through a general-purpose processor. The large logic fabric also allows protocol bridging, real-time data reduction, and hardware-assisted control to be consolidated into one programmable device.
Board design requires careful decoupling, multilayer construction, controlled clock routing, and complete BGA fanout. Because the package contains solder-ball connections rather than exposed leads, inspection and assembly require X-ray or equivalent process verification. The device should be paired with a correctly specified configuration memory and a validated clocking and power-delivery network.
This page consolidates distributor availability information, Artix-7 package details, speed-grade alternatives, application guidance, and design cautions that are distributed across individual distributor and datasheet listings. Engineering decisions should still be checked against the current AMD Artix-7 data sheet, package files, and the specific configuration memory interface.

主な用途
XC7A100T-2FT256I の用途: 6 件s: Industrial Automation and PLC Control, Data Acquisition and Signal Processing, Communications Gateway and Protocol Bridge, Test and Measurement Instrumentation, Embedded Video and Image Preprocessing, Aerospace and Defense Control Prototyping.
Industrial Automation and PLC Control
The XC7A100T-2FT256I fits industrial machine-control and automation designs because its 170 user I/O can support discrete sensors, encoders, actuator drivers, safety interlocks, and field-bus interfaces in one device. The -2 performance grade provides useful timing margin for parallel control logic, while the industrial ordering option targets extended-temperature operation. Engineers commonly implement state machines, motion sequencing, and signal conditioning in programmable logic instead of distributing those tasks across multiple processors. Before schematic release, assign I/O standards by bank, confirm the external clock requirement, and verify that every high-speed interface has the correct pull-up or termination network. The 256-FTBGA also requires careful escape-routing design because the dense ball field constrains access to power, ground, and high-speed nets.
おすすめ
Data Acquisition and Signal Processing
The XC7A100T-2FT256I is well suited to parallel ADC capture, digital filtering, decimation, and real-time analysis because 170 user I/O can accommodate multiple data buses and control channels. Parallel datapaths can sample, threshold, correlate, and reduce data before forwarding results to a processor, reducing serial transfer and processor overhead. The -2 grade offers additional timing margin for moderately clocked processing pipelines, and the Artix-7 device family is designed for low-power programmable logic rather than fixed hardware. The implementation must still account for input-slew requirements, bank voltage compatibility, clock skew, and the resolution of the configured logic. For mixed-signal boards, separate analog and digital return paths and use local decoupling so high-speed switching in the FPGA does not degrade the captured signal.
おすすめ
Communications Gateway and Protocol Bridge
The XC7A100T-2FT256I can implement parallel protocol conversion, packet framing, buffering, and interface isolation inside communications equipment. Its 170 I/O support multiple byte-wide buses and chip-select signals, allowing legacy parallel peripherals to be bridged to serial links implemented in programmable logic. The -2 grade provides margin for packet-processing pipelines, and the 256-FTBGA provides a compact single-chip implementation for gateways, bridges, and embedded concentrators. Practical designs should use clock-domain-crossing primitives for asynchronous interfaces, constrain all paths with appropriate clocking and I/O timing constraints, and keep high-speed serial routing away from sensitive analog sections. Because no separate Ethernet or transceiver PHY is identified in the supplied data, those companion functions must be selected from the specific board architecture rather than implied by this MPN.
おすすめ
Test and Measurement Instrumentation
The XC7A100T-2FT256I suits instrumentation that must acquire several channels, perform deterministic calibration, and generate or analyze control sequences in real time. Its 170 user I/O can connect source-measurement control logic, trigger interfaces, status flags, and parallel data channels, while the -2 performance grade supports deterministic timing margins. Engineers can place preprocessing, histogram accumulation, filtering, and calibration tables directly in programmable logic to shorten measurement latency. The design should reserve adequate pins for instrument triggers, reference control, and diagnostics, and it must provide clean reference and power rails to prevent gain error from appearing as measurement error. Timing closure also depends on the selected clock source and external memory interface, which are not specified in the supplied distributor records and must be confirmed against the complete design.
おすすめ
Embedded Video and Image Preprocessing
The XC7A100T-2FT256I is applicable to embedded image pipelines that need parallel pixel transport, thresholding, color processing, or hardware-assisted detection before the data reaches an application processor. The 170 I/O can support parallel source and destination interfaces, while the Artix-7 programmable fabric permits pixel-format conversion and line-buffer logic to be implemented without a separate FPGA family. The -2 performance grade gives additional timing margin for moderately fast raster pipelines, although actual throughput depends on the selected I/O standards, clock rates, and memory bandwidth. Designers should use registered outputs, constrain all source-synchronous interfaces, and follow AMD’s recommended package escape and via-in-pad construction. Video timing also requires deterministic reset handling and care to avoid unsupported I/O standards in voltage-matched banks.
おすすめ
Aerospace and Defense Control Prototyping
The XC7A100T-2FT256I can support control prototyping, telemetry conditioning, and interface-conversion experiments where reconfigurable logic is valuable. Its 170 user I/O enables multiple redundant sensor channels, command inputs, and status outputs, while the industrial-temperature option provides a documented basis for extended-temperature industrial evaluation. Engineers can implement fault-tolerant state machines, redundant data paths, and built-in test logic in the programmable fabric. Qualification for flight hardware is not implied by the industrial designation, so flight programs must apply their own screening, reliability, radiation, traceability, and documentation requirements. The board design should provide clean references, robust clocking, and carefully isolated power domains, while the 256-FTBGA assembly requires X-ray inspection and validated thermal cycling to detect assembly defects.

設計ノート
Build the power tree from the current AMD Artix-7 data sheet rather than from the distributor summaries. Separate the core, auxiliary, I/O, and configuration rails according to the selected bank voltages, then place the manufacturer-recommended bulk and high-frequency decoupling capacitors directly at the associated BGA power and ground balls. Keep switching-regulator loops away from the FPGA area and use a quiet reference source. Estimated dissipation is VDS-times-current only for a transistor and is not applicable here; the FPGA’s actual power must be obtained from the AMD power estimator for the selected resources, I/O activity, and junction-temperature assumptions.
Use the AMD FT256 package drawing and UG475 package files for the board footprint, ball assignment, and escape-routing strategy. The 256-FTBGA has no exposed perimeter leads, so power, ground, configuration pins, and high-speed I/O must escape through via arrays between or beneath the balls according to AMD guidance. Maintain the specified ball-pad and via-in-pad construction, account for solder-mask and paste stencil requirements, and validate assembly with X-ray inspection. Do not derive the ball map from distributor page titles because FT256 and similar Artix-7 packages can differ in pinout and voltage-bank assignments.
Assign every external interface to a bank whose voltage and I/O standard support the connected device, and observe the maximum drive, slew, pull-up, and input-capacitance limits. Give source-synchronous interfaces source-synchronous constraints, keep clock and data routing lengths matched, and use series termination where the AMD interface guidance calls for it. Isolate high-speed switching and edge-triggered inputs from precision analog sections. Configuration signals and JTAG should also be considered during placement because poor access can complicate production programming and boundary scan.
A common error is treating every XC7A100T 256-ball ordering code as automatically interchangeable. Before changing the device speed or temperature suffix, verify the exact package, temperature grade, screen option, configuration memory, and timing closure in the AMD ordering guide. Another error is assuming that identical ball counts guarantee identical ball maps or supported I/O standards. Use the exact package files, verify the PCB against them, and repeat static timing analysis after any speed-grade or tool-version change.
コンプライアンス情報
The supplied verified data identifies the industrial-temperature option and Artix-7 device family but provides no explicit RoHS, REACH, halogen-free, lead-free, conflict-minerals, or automotive-qualification statement. Compliance values are therefore marked unknown rather than assumed.
