XC2S50E-6TQ144C

The XC2S50E-6TQ144C is a Spartan®-IIE series FPGA in a 144-LQFP package from AMD. It integrates 384 CLBs (1,728 logic elements), 32,768 bits of on-chip RAM, and 102 user I/O pins to implement custom digital logic in a compact surface-mount package.

Designed for reprogrammable logic and system-level integration, this device targets applications where moderate logic density, on-chip memory and flexible I/O are required, with operation across a commercial temperature range and low-voltage supply.

Key Features

• Core Logic  384 CLBs providing 1,728 logic elements and an estimated 50,000 system gates for implementing combinational and sequential logic.
• On-chip Memory  32,768 total RAM bits of embedded memory for buffering, small FIFOs and local storage.
• I/O Count and Capacity  102 user I/O pins suitable for multi-signal interfacing and peripheral connectivity within the 144-LQFP footprint.
• Package and Mounting  144-LQFP (supplier device package listed as 144-TQFP 20×20) in a surface-mount form factor for compact board layouts.
• Power  Supported voltage supply range of 1.71 V to 1.89 V for core operation.
• Operating Range  Commercial grade operation, 0 °C to 85 °C.
• Standards and Family Features  As part of the Spartan-IIE family, the device benefits from family-level architectural features such as block RAM, configurable logic blocks, DLL-based clock control, and support for multiple I/O standards (as defined for the family).
• Environmental Compliance  RoHS-compliant manufacturing.

Typical Applications

• ASIC Replacement and Prototyping  In-system reprogrammability and CLB-based logic make this FPGA suitable for replacing mask-programmed ASICs during development and early production phases.
• Embedded Logic and Memory Interfaces  On-chip RAM and CLBs support local buffering, protocol handling and control logic for embedded designs that require modest memory and logic resources.
• Peripheral and Interface Bridging  With 102 I/O pins and family-level support for multiple I/O standards, this device can be used for custom peripheral interfaces and bridge functions.
• Board-Level Integration  Compact 144-LQFP surface-mount package enables integration into space-constrained PCB designs where reprogrammability and moderate gate count are needed.

Unique Advantages

• Moderate Logic Density: 1,728 logic elements enable implementation of substantial control and glue logic without the cost of larger FPGAs.
• Embedded Memory: 32,768 bits of on-chip RAM reduce external memory requirements for small buffers and state storage, simplifying BOM and board design.
• Flexible I/O Count: 102 user I/O pins allow multiple peripherals and interfaces to be routed directly to the FPGA, minimizing additional I/O expander components.
• Compact, Surface-Mount Package: 144-LQFP (144-TQFP 20×20) offers a balance of pin count and PCB area for mid-density designs.
• Low-Voltage Core: 1.71–1.89 V supply supports designs targeting low-voltage FPGA implementations.
• Compliance and Support: Commercial temperature rating and RoHS compliance meet common procurement and environmental requirements for consumer and industrial electronic products.
