XC3S50A-4VQG100I

The XC3S50A-4VQG100I is a Spartan®-3A Field Programmable Gate Array (FPGA) from AMD supplied in a 100-TQFP (100-VQFP, 14×14 mm) surface-mount package. It delivers a balance of programmable logic, on-chip memory, and I/O density for industrial-grade embedded designs operating across a wide temperature range.

With 1,584 logic elements, 176 CLBs, approximately 55.3 kbits of on-chip RAM and 68 user I/O pins, this FPGA is suited for compact systems that require reconfigurable digital logic and deterministic I/O in industrial environments.

Key Features

• Core Logic  1,584 logic elements and 176 CLBs provide resource capacity for implementing custom digital functions and state machines.
• Embedded Memory  55,296 bits (approximately 0.055 Mbits) of on-chip RAM for data buffering, FIFOs, and small lookup tables.
• I/O Density  68 user I/O pins support multiple external interfaces and signal connections in a compact package.
• Gate Count  50,000 gates of logic capacity for mid-range configurable implementations.
• Power Supply  Operates from a core voltage range of 1.14 V to 1.26 V to match regulated FPGA power rails.
• Industrial Temperature Range  Rated for operation from -40 °C to 100 °C and specified as Industrial grade for demanding ambient conditions.
• Package & Mounting  Available in a 100-TQFP (100-VQFP, 14×14 mm) surface-mount package for space-constrained PCB layouts.
• Environmental Compliance  RoHS compliant.

Typical Applications

• Industrial control  Deterministic logic and robust operating temperature range make this FPGA suitable for PLCs, motor controllers, and factory automation interfaces.
• Embedded prototyping  1,584 logic elements and on-chip RAM provide a development platform for proof-of-concept digital designs and algorithm validation.
• I/O bridging and protocol translation  68 I/O pins enable implementation of custom interface logic, bridging disparate bus standards or aggregating sensors and actuators.
• Signal conditioning and pre-processing  On-chip resources can be used for preprocessing sensor data, filtering, and deterministic timing tasks before handing data to a host MCU or SoC.

Unique Advantages

• Balanced logic and memory: 1,584 logic elements combined with 55,296 bits of embedded RAM let you implement both control logic and local data storage on a single device.
• Industrial-grade temperature performance: Rated from -40 °C to 100 °C, enabling deployment in temperature-challenging environments.
• Compact, surface-mount packaging: 100-TQFP (14×14 mm) package supports dense PCB designs while providing significant I/O count.
• Narrow core voltage window: 1.14 V to 1.26 V supply range simplifies power budgeting for regulated FPGA core rails.
• Compliance-ready: RoHS compliance supports environmentally conscious product requirements.
