XC3S50-4TQ144C Présentation
A field-programmable gate array is a semiconductor whose logic, interconnects and dedicated resources are configured after manufacture. The FPGA product hierarchy places the XC3S50-4TQ144C among FPGAs, programmable-logic devices and digital semiconductors. Unlike a fixed-function application-specific integrated circuit, an FPGA can implement parallel control logic, state machines, protocol interfaces and data-processing pipelines in one configurable device.
The verified listing identifies 192 logic array blocks, 97 user I/O pins, 73,728 RAM bits and 1,728 logic cells. These resources support concurrent datapaths and moderate control complexity. The 1.2 V core supply can simplify power architecture when paired with appropriate I/O voltage selection, although the complete board design must follow the manufacturer’s bank-specific voltage and decoupling guidance.
Architecturally, the Spartan-3 device combines configurable logic blocks, programmable routing, dedicated block RAM and hard input/output resources. This allows designers to balance parallel logic against memory-based pipelines. Compared with larger members of the Spartan-3 family, the XC3S50 emphasizes compact capacity and cost rather than maximum logic density.
Typical uses include industrial control, embedded instrumentation, communication-interface bridges, low-pin-count peripheral expansion, digital signal-processing front ends and general embedded control. A 144-LQFP package also provides a familiar gull-wing footprint for conventional multilayer PCB assembly, although its fine pitch requires controlled soldering and inspection.
Designers should verify the complete pinout, supported I/O standards, configuration interface and unused-pin requirements against the manufacturer datasheet before layout release. The sparse verified data does not expose a manufacturer part page or complete electrical table, so power, timing and pin details must not be inferred.
This page consolidates verified distributor specifications, package evidence, sourcing links and candid data-gap notes. It also separates exact published facts from unavailable electrical, pricing, lifecycle and pin-level information so engineers can make a safer FPGA selection.

Applications typiques
XC3S50-4TQ144C convient pour 6 applications: Industrial Control Logic, Communication Interface Bridge, Digital Signal-Processing Front End, Embedded Instrumentation Control, Peripheral Expansion and Glue Logic, Data Acquisition Control.
Industrial Control Logic
The XC3S50-4TQ144C fits compact programmable controllers when a design can be implemented with its verified 1,728 logic cells, 73,728 RAM bits and 97 user I/Os. It can coordinate discrete I/O, sequencing logic and small internal data paths in a single Spartan-3 device. The -4 speed designation supports legacy timing designs, but industrial suitability still depends on confirming the exact temperature range, I/O standards, isolation requirements and long-term supply. For a new controller, engineers should compare this obsolete-family choice against currently supported safety-qualified or serviceable devices.
Recommandé
Communication Interface Bridge
The Spartan-3 architecture can support parallel-to-serial logic, framing, buffering and protocol state machines where deterministic parallel hardware is preferable. XC3S50-4TQ144C offers 97 user I/O and 1,728 logic cells, making it relevant to legacy bridges joining a microprocessor bus to a serial transceiver. Signal rate remains limited by the selected I/O standard, routing and verified timing conditions. The datasheet mirror should be consulted for bank voltage, timing and pin constraints before configuration.
Recommandé
Digital Signal-Processing Front End
XC3S50-4TQ144C can host parallel filters, counters, decoders and fixed-point pipelines when throughput matters more than processor flexibility. Its verified 73,728 RAM bits provide buffering resources, while 1,728 logic cells support moderate datapath parallelism. A legacy Spartan-3 implementation is most credible for stable algorithms with already validated timing. Engineers must establish clock, setup, hold and I/O timing from the manufacturer family documentation rather than relying on the general 630 MHz listing.
Recommandé
Embedded Instrumentation Control
The FPGA can combine measurement sequencing, calibration tables, status tracking and display-control logic around an embedded processor. Its 97 user I/Os and modest internal RAM make it appropriate for small instrumentation control planes rather than large local buffers. A 144-LQFP footprint supports conventional board assembly, although every connected processor, memory and peripheral must be reviewed for voltage compatibility. Obsolete-family tooling and supply continuity are the main risks for long-lifecycle test equipment.
Recommandé
Peripheral Expansion and Glue Logic
XC3S50-4TQ144C can serve as a companion programmable-logic device for legacy systems whose bus timing, interrupt sequencing or peripheral arbitration is awkward for firmware. Multiple dedicated I/O and 1,728 logic cells allow simultaneous state machines and data steering, while internal RAM can reduce external storage demands. Validate clock-domain crossings and pin assignments carefully because the supplied evidence does not expose the full pinout or supported I/O matrix.
Recommandé
Data Acquisition Control
In legacy acquisition systems, XC3S50-4TQ144C can implement sample sequencing, channel selection, trigger control and data capture control around external converters. The verified 97 user I/Os are useful for converter control and status signals, while 1,728 logic cells allow several parallel control paths. Throughput must be derived from actual routing and timing rather than the nominal frequency. For new precision-instrument designs, verify converter compatibility, grounding, analog isolation and converter-specific timing.

Notes de conception
Treat the 144-LQFP land pattern as a fine-pitch gull-wing assembly problem: inspect paste volume, solder bridging at adjacent leads and pin-one orientation before fabrication. Place decoupling close to the relevant supply pins and route clocks away from high-slew-rate outputs. Because the supplied evidence does not contain a complete verified pin table, do not freeze a symbol or footprint from an unverified generic library.
The verified core supply is 1.2 V, but this value alone does not define every power rail or bank voltage. Before schematic release, obtain the manufacturer family documentation and verify supply tolerances, sequencing, decoupling and I/O-bank requirements. Estimated power cannot be calculated responsibly because active utilization, I/O loading, output activity, voltage and device speed were not supplied.
Do not substitute an FPGA merely because another member uses a 144-TQFP package. XC3S50A candidates use a different Spartan-3A architecture, and an -5 candidate changes the speed grade; both can invalidate timing, resource mapping or pin assumptions. Preserve the original bitstream only for an exactly device-compatible replacement and run timing, I/O, startup and functional regression tests before use.
Informations de conformité
The supplied search results do not contain authoritative compliance declarations for this exact MPN. Compliance fields are therefore unknown rather than assumed.
