XC2S50E-6PQ208C

The XC2S50E-6PQ208C is a Spartan®-IIE field-programmable gate array (FPGA) offered in a 208-pin BFQFP surface-mount package. It provides reprogrammable digital logic resources and on-chip memory suitable for prototyping, middle-density logic integration, and system interfacing tasks.

With 1,728 logic elements, 32,768 bits of embedded RAM and 146 user I/O pins, this device targets applications that require flexible I/O connectivity, moderate on-chip buffering and the ability to update logic in-system. The device operates over a 1.71–1.89 V core supply range and is specified for commercial temperature operation (0 °C to 85 °C).

Key Features

• Core Logic — 1,728 logic elements provide reprogrammable logic capacity for glue logic, finite-state machines, and medium-complexity digital functions.
• Embedded Memory — 32,768 bits of on-chip RAM (approximately 0.033 Mbits) for data buffering, FIFOs and small lookup tables.
• I/O Count and Flexibility — 146 user I/O pins support diverse interface needs and board-level connectivity.
• Logic Density — Equivalent to approximately 50,000 system gates for mapping a range of combinational and sequential logic functions.
• Package and Mounting — 208-BFQFP (208-PQFP, 28×28) surface-mount package for compact board integration.
• Power Supply — Core supply range of 1.71 V to 1.89 V for compatibility with system power domains.
• Operating Range — Commercial grade operation from 0 °C to 85 °C for typical commercial and lab environments.
• Standards and Compliance — RoHS compliant, supporting modern environmental requirements.
• Spartan®-IIE Family Capabilities — Family-level features include block RAM and distributed RAM architecture, selectable I/O standards and integrated clock management elements (as described in the Spartan-IIE data material).

Typical Applications

• Prototyping and Development — Use for board- and system-level prototyping where reprogrammable logic accelerates iteration and validation.
• ASIC Replacement and Glue Logic — Implement medium-complexity glue logic and interface conversion to reduce BOM and shorten development cycles compared to mask-programmed devices.
• Interface Bridging — Provide protocol translation and parallel/serial interface control leveraging the device’s high I/O count and embedded memory.
• Embedded Control — Perform custom control logic, finite-state machines and moderate buffering tasks in compact embedded systems.

Unique Advantages

• Reprogrammable Flexibility: In-system reprogrammability allows design updates without hardware changes, enabling rapid iteration and field upgrades.
• Balanced On-Chip Resources: Combination of 1,728 logic elements and 32,768 bits of RAM supports a wide range of medium-complexity designs without immediate need for external memory.
• Generous I/O Capacity: 146 I/O pins simplify integration with sensors, peripherals and system buses, reducing external interface components.
• Compact Surface-Mount Package: 208-BFQFP (28×28) package enables dense PCB layouts while maintaining accessible pinout for mixed-signal boards.
• Commercial Temperature Rating: Specified 0 °C to 85 °C operation aligns with typical commercial and lab deployments.
• Regulatory Compliance: RoHS compliance supports environmentally conscious product designs.
