XC3S50A-4VQG100C

The XC3S50A-4VQG100C is a Spartan®-3A field programmable gate array (FPGA) IC from AMD supplied in a 100-TQFP package. It delivers a compact, programmable logic solution with 1,584 logic elements, on-chip memory, and 68 user I/O pins for commercial embedded and digital designs.

Designed for surface-mount assembly and commercial temperature operation, this device targets FPGA-based development where integration of logic, RAM, and I/O in a small footprint is required.

Key Features

• Core Logic — 1,584 logic elements providing programmable resources for digital logic implementation and custom datapaths.
• Embedded Memory — 55,296 bits of on-chip RAM to support buffering, state storage, and small lookup tables within the FPGA fabric.
• I/O — 68 user I/O pins for interfacing with peripherals, sensors, and external logic devices.
• Gate Count — 50,000 gates indicative of the device capacity for combinational and sequential logic designs.
• Power — Operates from a core supply range of 1.14 V to 1.26 V, enabling compatibility with low-voltage system domains.
• Package & Mounting — 100-TQFP package (supplier device package: 100-VQFP, 14×14) in a surface-mount form factor for compact PCB layouts.
• Temperature Grade & Compliance — Commercial grade operation from 0 °C to 85 °C and RoHS compliant for environmental conformity.

Typical Applications

• Prototyping and Development — Use the FPGA for evaluating custom logic, proof-of-concept digital designs, and iterative firmware development.
• Embedded Control — Implement glue logic, simple state machines, and control interfaces where moderate logic density and on-chip RAM are required.
• Peripheral and Sensor Interfaces — Leverage the 68 I/O pins to aggregate signals from sensors, actuators, and I/O buses in compact systems.

Unique Advantages

• Compact, integrated FPGA solution: Combines logic, embedded RAM, and 68 I/O pins in a single 100-TQFP surface-mount package to reduce board-level component count.
• Low-voltage core operation: The 1.14 V–1.26 V supply enables integration into systems with low-voltage power domains.
• Commercial temperature suitability: Rated for 0 °C to 85 °C, making it appropriate for general-purpose commercial electronics.
• RoHS compliant: Meets RoHS environmental requirements, simplifying regulatory considerations for many markets.
• Clearly defined capacity: 1,584 logic elements and 55,296 bits of RAM provide measurable resources for design planning and partitioning.
