XC3S50-4PQG208C

The XC3S50-4PQG208C is a Spartan®-3 Field Programmable Gate Array (FPGA) in a 208-BFQFP package. It provides a compact, reconfigurable logic resource with on-chip memory and flexible I/O for a range of commercial programmable-logic applications.

Key Features

• Core Logic 1728 logic elements and 192 configurable logic blocks (CLBs) provide the core programmable fabric for implementing custom digital logic.
• Embedded Memory Approximately 0.074 Mbits (73,728 bits) of on-chip RAM for buffering, small lookup tables, and state storage.
• I/O 124 user I/O pins to support peripheral interfaces and board-level signal connectivity.
• Gate Count 50,000 gates indicative of the device's overall integration level for glue logic and mid-density applications.
• Power Core supply range of 1.14 V to 1.26 V to match required core voltage rails.
• Package & Mounting 208-BFQFP (supplier package 208-PQFP, 28×28 mm) in a surface-mount form factor for compact PCB layouts.
• Operating Range Commercial temperature rating from 0 °C to 85 °C suitable for general-purpose environments.
• Environmental Compliance RoHS compliant to support lead-free manufacturing requirements.

Typical Applications

• Custom Logic Implementation Implement glue logic, protocol translators, and finite-state machines where field-programmable logic is required.
• Interface Bridging Use available I/O to bridge and adapt signals between different peripherals and subsystems on a PCB.
• Prototyping and Development Deploy as a mid-density FPGA for design validation and early hardware bring-up.

Unique Advantages

• Balanced Integration: Combines 1728 logic elements with on-chip RAM and 124 I/O to address a variety of mid-density design needs without excess board-level components.
• Compact Surface-Mount Package: The 208-BFQFP package supports space-efficient board layouts while maintaining ample I/O connectivity.
• Low-Voltage Core: Narrow core supply range (1.14 V to 1.26 V) simplifies power-supply design for the FPGA core.
• Commercial Temperature Rating: Rated 0 °C to 85 °C for standard commercial applications where moderate operating range is acceptable.
• RoHS Compliant: Conforms to lead-free manufacturing requirements for environmentally responsible production.

Why Choose XC3S50-4PQG208C?

The XC3S50-4PQG208C positions as a mid-density, commercial-grade FPGA offering a practical mix of logic, memory, and I/O in a compact 208-BFQFP footprint. It is well suited to designs that require configurable digital logic, moderate on-chip storage, and flexible interfacing without moving to higher-density FPGA families.

Designers and procurement teams benefit from a device that delivers integration and predictable supply/temperature characteristics, making it appropriate for prototypes, consumer electronics, and general-purpose embedded applications where commercial-grade components are specified.
