XA3S50-4PQG208Q - 125 MHz Spartan-3 XA FPGA | AMD
料号： XA3S50-4PQG208Q ✗ 停产XA3S50-4PQG208Q 概述
A field-programmable gate array is a semiconductor whose digital logic, memory, and I/O behavior are defined after manufacture through a configuration bitstream. Within the product hierarchy, the XA3S50-4PQG208Q is a Spartan-3 XA FPGA, combining configurable logic blocks, block RAM, programmable I/O standards, and dedicated configuration resources on one integrated device. This makes it useful when a fixed logic design must be updated without replacing the PCB.
Key features include support for 17 single-ended I/O standards and seven differential standards, including LVDS. The advance product specification lists a maximum data-transfer rate of 622 Mb/s per I/O. Digitally controlled on-chip termination is also identified in the supplied specification data, helping reduce external termination components on suitable high-speed interfaces. The -4 speed designation corresponds to the verified 125 MHz maximum operating frequency.
The device includes 73,728 bits of RAM, providing dedicated storage alongside the 1,728 logic cells. Its 124 user I/O pins provide substantial connectivity for control logic, data acquisition, communications, and general-purpose embedded processing. As an AEC-Q100-qualified automotive FPGA, it supports designs requiring a qualified programmable logic platform rather than a fixed-function controller.
Typical uses include automotive body and chassis electronics, industrial control modules, data-acquisition equipment, communication gateways, and embedded control systems. The combination of 125 MHz operation, 124 I/O, 73,728 RAM bits, and broad I/O-standard support suits designs that interface multiple external signal domains while retaining field-updatable configuration.
Designers should verify every voltage bank, I/O standard, clocking requirement, configuration interface, and power-budget assumption against the manufacturer datasheet before layout release. Because the supplied data does not provide a complete pin table, this page does not publish an inferred 208-pin mapping; use the manufacturer documentation for board-level implementation.
This page consolidates verified distributor specifications, automotive qualification information, sourcing data, and selection guidance. It also distinguishes available same-family alternatives by package and qualification, while explicitly identifying missing technical details instead of estimating unpublished pinout, timing, or power values.

典型应用
XA3S50-4PQG208Q 适用于 6 应用s: Automotive Body Control Module, Industrial Data-Acquisition System, Industrial Communication Gateway, Automotive Sensor Fusion Controller, Programmable Logic Control System, Video and Image Processing Controller.
Automotive Body Control Module
The XA3S50-4PQG208Q fits automotive body-control and chassis modules because it combines AEC-Q100 qualification with 124 user I/O pins, 1,728 logic cells, and a verified 125 MHz operating frequency. Its 73,728 RAM bits can hold configuration, diagnostic, and state data while programmable logic manages switches, lamps, door modules, and sensor inputs. The 17 single-ended and seven differential I/O standards give the module flexibility for mixed automotive signal domains. Engineers should allocate voltage banks carefully, qualify every interface for automotive EMC requirements, and confirm that the selected Spartan-3 XA bitstream and configuration method meet the vehicle-program lifecycle.
推荐
Industrial Data-Acquisition System
The XA3S50-4PQG208Q is suitable for industrial acquisition and test systems that need reconfigurable timing and multiple mixed-signal interfaces. Its 124 user I/O pins can connect sensors, counters, trigger logic, and communication transceivers, while 1,728 logic cells and 73,728 RAM bits support control, buffering, and stateful pipeline functions. The verified 125 MHz maximum frequency provides ample clocking margin for many acquisition architectures. Because the supplied data does not specify supported analog input ranges, designers must use external converters and condition the FPGA interface according to the manufacturer I/O-standard table.
推荐
Industrial Communication Gateway
The XA3S50-4PQG208Q can implement protocol conversion and packet handling in an industrial communication gateway because its 124 I/O pins support several external interfaces while 73,728 RAM bits accommodate buffering. Its programmable fabric allows protocol-specific framing, filtering, and error handling to be updated independently of the PCB. The seven differential I/O standards, including LVDS, and the listed 622 Mb/s per-I/O capability can support suitable high-speed links after timing and signal-integrity analysis. A practical design should reserve separate voltage banks for incompatible standards and use the 125 MHz operating limit as the basis for initial clock planning.
推荐
Automotive Sensor Fusion Controller
The XA3S50-4PQG208Q can combine digital sensor inputs and control outputs in an automotive sensor-fusion controller. The 1,728 logic cells provide parallel logic for filtering, timestamp association, diagnostics, and fault handling, while the 124 I/O pins offer connectivity to external sensors and actuators. Its AEC-Q100 qualification is a significant advantage over an unqualified general-purpose FPGA, although system-level functional safety and environmental validation remain necessary. The designer should use the seven differential standards and LVDS support only where electrical, timing, and layout conditions are satisfied, and should separate incompatible voltage standards into correctly configured banks.
推荐
Programmable Logic Control System
The XA3S50-4PQG208Q provides a flexible platform for programmable logic control where field updates are valuable and fixed wiring would otherwise require redesign. Its 192 CLBs and 1,728 logic cells can implement state machines, counters, interlocks, alarm logic, and timing functions, while 73,728 RAM bits support buffering and configuration data. A maximum operating frequency of 125 MHz supports fast control and data paths. Because the exact internal memory organization and I/O timing were not included in the supplied records, engineers must consult the manufacturer datasheet for block RAM, clock routing, and pin-specific timing before finalizing the control architecture.
推荐
Video and Image Processing Controller
The XA3S50-4PQG208Q can support lightweight video timing, pixel routing, test-pattern generation, or interface conditioning where the required throughput fits its 125 MHz operating limit and 124 I/O capacity. The seven differential standards and LVDS support are useful for compatible source-synchronous interfaces, while the fabric can implement line counters, synchronization, and control logic. However, the verified 73,728 RAM bits are relatively limited, so frame buffering normally requires external memory or a more capable FPGA. The design should include timing constraints, bank voltage planning, and controlled-impedance routing rather than treating the listed 622 Mb/s per-I/O figure as guaranteed system bandwidth.

设计说明
Use the manufacturer package drawing to define the 208-pin PQFP land pattern, solder-mask expansion, and paste apertures; the supplied data confirms a 0.50 mm terminal pitch but does not provide dimensions or exposed-pad details. Match the exact XA3S50 ordering code before releasing the footprint, and verify pin 1 orientation against the package drawing and PCB assembly documentation. Because the XAIPART package library has no validated 208-pin PQFP illustration, do not rely on a generic drawing for manufacturing dimensions.
Plan the 1.2 V core rail and all I/O voltage banks independently after checking the manufacturer power table. The verified records do not specify static current, dynamic current, startup sequencing, or supply tolerances, so those values must not be estimated. Use local decoupling and adequate plane connectivity, and verify sequencing against the configuration requirements. If the selected alternative changes only the speed or qualification suffix, retain the same validated power architecture unless the manufacturer documentation states otherwise.
Plan LVDS and other differential interfaces with controlled-impedance routing, matched pair lengths, appropriate reference planes, and receiver placement that avoids stubs. Although the advance specification lists 622 Mb/s per I/O, this is not a guaranteed application throughput. Validate each interface against its voltage standard, clock topology, timing constraints, and the manufacturer's I/O guidance. Use digitally controlled termination only on pins and configurations explicitly supported by the datasheet.
Do not treat the XA3S50, XA3S400, or XA3S500E family names as interchangeable solely because some use a 208-pin PQFP. Resource counts, supported I/O standards, bitstreams, speed grades, and qualification can differ. For an exact substitution, compare the manufacturer ordering information, pin table, electrical limits, configuration method, and AEC-Q100 records. The supplied evidence does not establish XA3S400-4PQG208Q or XA3S500E-4PQG208Q as drop-in replacements, so neither is listed as an alternative.
