XC7A12T-3CPG238E - -3 Speed Grade Artix-7 FPGA | Xilinx
部品番号: XC7A12T-3CPG238E ✓ 生産中XC7A12T-3CPG238E 概要
An FPGA is a semiconductor whose digital logic, interconnect, and configurable I/O blocks are programmed after manufacture. Artix-7 devices belong to the broader FPGA and programmable-logic hierarchy, combining configurable logic, block RAM, DSP resources, and programmable I/O in one package. This makes the XC7A12T-3CPG238E suitable for embedded systems that need hardware-level parallelism and design flexibility without the resource level of a larger FPGA.
The catalog listing identifies 12,800 logic cells, 112 I/O, 238 terminals, and a -3 device speed designation. Its square LFBGA package places the device in the CSBGA-238 package family, providing a dense PCB land pattern suitable for compact industrial, communications, instrumentation, and embedded-control equipment. The part is also identified as RoHS compliant by its assembly listing.
The XC7A12T-3CPG238E shares the XC7A12T device designation and 238-ball package with speed-grade and temperature-grade variants. This common mechanical and logical basis supports simplified product-family planning, although a migration must still account for timing closure, junction-temperature limits, power characteristics, configuration compatibility, and the exact ordering code. The AMD Artix-7 package pinout files should be used to validate every PCB connection before fabrication.
Typical uses include industrial data acquisition, camera and image-processing pipelines, communications interfaces, embedded control, test equipment, and sensor-processing systems. The -3 speed grade is appropriate when timing performance is a principal selection factor. Designers should define clock constraints, pin assignments, power rails, and configuration requirements early in the schematic and PCB-layout process.
PCB implementation requires careful power-plane distribution, decoupling, and escape-routing strategy for the 238-ball BGA. Use the manufacturer package drawing and pinout files for land patterns, ball assignments, thermal-pad treatment, and assembly constraints. Because fine-pitch BGA assembly can hide shorts and opens, inspection methods and soldering profile must match the package requirements.
This product record combines package, logic-resource, ordering-code, and lifecycle information with same-package family comparisons and practical implementation guidance. It also distinguishes mechanical compatibility from timing-grade and environmental differences, helping engineers select a replacement without overlooking the constraints that determine production suitability.

主な用途
XC7A12T-3CPG238E の用途: 6 件s: Industrial Data Acquisition, Industrial Sensor Networking, Communications Interface, Camera and Image Preprocessing, Test and Measurement, Embedded Control Platform.
Industrial Data Acquisition
The XC7A12T-3CPG238E fits compact industrial acquisition systems that must combine parallel sensor interfaces, control logic, and protocol handling in a single programmable device. Its 12,800 logic cells provide capacity for control paths, acquisition sequencing, status logging, and interface translation, while 112 I/O simplify connections to external converters and sensors. The -3 speed designation is useful when acquisition pipelines require tighter timing margins. Place the device in a multilayer PCB with short point-to-point routing, use the official 238-ball land pattern, and keep high-current switching nodes away from sensitive input and clock nets.
おすすめ
Industrial Sensor Networking
The XC7A12T-3CPG238E can support distributed sensor nodes that require deterministic parallel sensing, local filtering, and communications framing. The FPGA's 12,800 logic cells allow engineers to implement acquisition control, threshold logic, data packing, and interface-specific state machines concurrently. Its 112 I/O provide dedicated resources for sensors, interrupts, and communications, while the -3 grade supports timing-sensitive processing. For industrial deployment, review the exact E-grade temperature limits, isolate noisy actuator drivers, provide local decoupling at supply balls, and verify the complete design against the 238-ball package constraints.
おすすめ
Communications Interface
The XC7A12T-3CPG238E is suitable for protocol converters and communications front ends that benefit from programmable parallel data paths. Its 12,800 logic cells can support framing, CRC generation, channel alignment, buffering, and supervisory logic, while 112 I/O allow high-throughput source-synchronous interfaces. The -3 speed designation helps preserve margin in clocked datapaths. Engineers should use the manufacturer package pinout to select clock-capable and regular I/O pins, keep input and output timing constraints synchronized, and route clocks with controlled return paths to minimize data corruption and electromagnetic interference.
おすすめ
Camera and Image Preprocessing
The XC7A12T-3CPG238E can implement camera-facing pixel transport, timing generation, preprocessing, and capture control in compact embedded vision systems. Its configurable logic allows parallel pixel lanes and control signals to be synchronized, while the 12,800-cell resource level is suitable for moderate pipeline stages and interface adapters rather than unrestricted image processing. The -3 grade supports demanding clock domains. Keep sensor data traces short and matched, terminate clocks according to the interface specification, isolate switching outputs, and validate setup and hold timing for every source-synchronous path before hardware release.
おすすめ
Test and Measurement
The XC7A12T-3CPG238E can implement deterministic timing, sequence, and protocol logic for compact test and measurement instruments. The 12,800 logic cells allow parallel execution of acquisition sequences, trigger matrices, status checks, and data-format conversion, while 112 I/O provide connections to instruments and fixtures. Its -3 designation supports timing-sensitive control paths and counters. Designers should isolate high-energy switching stages, use controlled clock distribution, validate input thresholds and output timing for every supported I/O standard, and reserve the configuration pins exactly as defined by the manufacturer package documentation.
おすすめ
Embedded Control Platform
The XC7A12T-3CPG238E works well as the programmable control core of an embedded equipment platform, combining peripheral bridges, state machines, timing, and supervisory logic in one device. Its 12,800 logic cells and 112 I/O are well matched to medium-complexity control boards requiring flexible pin assignment. The -3 speed grade provides additional timing margin for coordinated control paths. A robust implementation should separate sensitive analog and reference circuitry from FPGA supply currents, use multiple local bypass capacitors as specified by the device guidance, provide clean configuration startup, and test boundary scan and production programming procedures.

設計ノート
Build the PCB from the official Artix-7 238-ball package drawing and pinout file rather than a generic CSBGA footprint. Confirm ball coordinates, exposed thermal-pad requirements, solder-mask and paste details, and assembly tolerances before release. Provide clean escape routing from all BGA balls and inspect fine-pitch assemblies with X-ray or an equivalent process capable of detecting bridged balls.
Separate FPGA core, I/O, and auxiliary supply routing as required by the device power architecture, and place local high-frequency decoupling directly at the relevant package balls. Keep high-current switching supplies and external regulators physically separated from sensitive clock and user-I/O routing. Validate voltage tolerances, power-up sequencing, and startup current before applying the power rails in hardware.
Assign clocks only to pins qualified for the intended clocking function, constrain all clock domains explicitly, and maintain controlled return paths beneath high-speed interfaces. Keep source-synchronous data routing short and length-matched where required by the external device. Review every pin against the Artix-7 package pinout because a valid package position does not guarantee support for every I/O standard.
Do not treat a shared 238-ball footprint as proof of an interchangeable production part. The speed designation, temperature suffix, configuration requirements, timing limits, power behavior, and qualification can change across ordering codes. For every proposed migration, regenerate constraints and bitstreams, rerun timing and power signoff, verify the manufacturing test plan, and confirm the exact ordering code before purchase.
