XC2S400E-6FT256C

The XC2S400E-6FT256C is a commercial-grade Spartan®-IIE field programmable gate array supplied in a 256-LBGA package. It delivers 10,800 logic elements and approximately 0.16 Mbits of embedded memory, providing a balance of logic density, on-chip RAM and I/O capacity for embedded designs and logic-centric applications. Its supported supply voltage and operating temperature range make it suitable for standard commercial electronic products and development projects.

Key Features

• Logic Capacity  10,800 logic elements and an indicated 400,000 gates provide substantial programmable logic for combinational and sequential functions.
• Embedded Memory  163,840 total RAM bits (approximately 0.16 Mbits) for on-chip buffering, state storage and small lookup tables.
• I/O Resources  182 user I/O pins to support multiple peripheral interfaces and external device connections.
• Power Supply  Operates from a 1.71 V to 1.89 V supply, allowing integration into systems with constrained core voltage domains.
• Package & Mounting  256-LBGA package (supplier device package: 256-FTBGA, 17×17) in a surface-mount form factor for compact board integration.
• Operating Conditions  Commercial temperature grade with an operating range of 0 °C to 85 °C suitable for standard consumer and commercial electronics.
• RoHS Compliant  Manufactured in compliance with RoHS requirements for lead-free assembly and environmental standards.

Typical Applications

• Embedded Systems  Use the FPGA’s 10,800 logic elements and on-chip RAM to implement custom control logic and data handling in embedded designs.
• I/O Expansion and Bridging  Leverage 182 I/O pins to interface between multiple peripherals, protocols or buses on a single device.
• Prototyping and Development  Suitable for hardware validation and iterative design where programmable logic and reconfiguration are required.
• Memory-Centric Logic  On-chip RAM enables buffering and small data storage tasks directly within the FPGA fabric.

Unique Advantages

• Balanced Logic and Memory: 10,800 logic elements paired with approximately 0.16 Mbits of embedded memory support a wide range of mid-density designs.
• Generous I/O Count: 182 user I/Os reduce the need for external I/O expanders and simplify board-level connectivity.
• Compact, Surface-Mount Package: 256-LBGA (256-FTBGA, 17×17) delivers high pin density in a space-efficient footprint for PCB-constrained applications.
• Commercial Temperature Rating: Operates across 0 °C to 85 °C, matching the requirements of mainstream consumer and commercial electronic products.
• RoHS Compliant: Meets environmental lead-free manufacturing requirements for modern assembly processes.
• Controlled Core Voltage: Narrow supply range (1.71 V–1.89 V) enables predictable integration into systems with designed core voltage rails.
