XC2S50-5FG256I Key Features and Benefits

High-Density Programmable Logic Architecture

The XC2S50-5FG256I features a robust CLB (Configurable Logic Block) array organized in a 16×24 matrix, providing 384 total CLBs. Each CLB contains four logic cells with look-up tables (LUTs), flip-flops, and dedicated carry logic for efficient arithmetic operations. This architecture enables designers to implement complex digital functions while maintaining optimal resource utilization.

Flexible Memory Resources

This Spartan-II FPGA integrates both distributed and block RAM capabilities. The 24,576 bits of distributed RAM allow for small, fast memory implementations close to logic resources. Additionally, 32K bits of dual-port block RAM support larger memory requirements for data buffering, FIFO implementations, and lookup table applications.

Industrial Temperature Range Operation

The “I” suffix in XC2S50-5FG256I designates industrial-grade operation from -40°C to +85°C. This extended temperature range makes the device suitable for harsh environment applications including industrial automation, outdoor equipment, and automotive systems where temperature extremes are common.

Comprehensive I/O Standards Support

The XC2S50-5FG256I supports multiple I/O standards to ensure seamless interface compatibility:

• LVCMOS (3.3V, 2.5V, 1.8V)
• LVTTL
• PCI 33MHz and 66MHz compliant
• SSTL2 and SSTL3 (DDR memory interfaces)
• HSTL Class I, III, and IV
• GTL and GTL+
• AGP-2X

XC2S50-5FG256I Configuration Options

The XC2S50-5FG256I supports multiple configuration modes for maximum design flexibility:

Master Serial Mode

The FPGA reads configuration data from an external serial PROM automatically upon power-up. This mode is ideal for standalone applications requiring autonomous boot capability.

Slave Serial Mode

An external processor or controller provides configuration data serially. This mode enables system-level configuration management and in-system updates.

Slave Parallel Mode

Configuration data is loaded through an 8-bit parallel interface for faster programming. This mode reduces configuration time for time-critical applications.

JTAG Boundary Scan Mode

IEEE 1149.1 compliant boundary scan enables configuration, debugging, and testing through a standard 4-wire interface. This mode supports in-system programming and board-level testing.
