AMD XC2S150-5FGG256C

Overview

XC2S150-5FGG256C from AMD (formerly Xilinx) is a Spartan-II family FPGA with 150,000 system gates, 1728 configurable logic blocks (CLBs), 256-pin Fine-Pitch Ball Grid Array (FBGA) package, and -5 speed grade (5 ns CLB delay). It is used in industrial control logic, digital signal preprocessing, and low-cost communication interface bridging.

For engineers reviewing the XC2S150-5FGG256C datasheet, pinout, applications, or equivalent options, key selection considerations include I/O count (176 user I/Os), distributed RAM capacity (72 Kb), global clock resources (4 dedicated clock pins), and compliance with IEEE 1149.1 JTAG boundary-scan test standard.

Technical Context

The XC2S150-5FGG256C implements synchronous logic using four-input LUTs and flip-flops per CLB, supports SelectIO™ technology for single-ended and differential signaling (LVCMOS, LVTTL, PCI, HSTL, SSTL), and includes dedicated carry logic for high-speed arithmetic. It integrates up to 72 Kb of distributed RAM and supports in-system configuration via JTAG or serial PROM.

Configuration is performed through the internal startup sequence after power-on, with support for master serial, slave serial, and boundary-scan modes. The device uses 2.5 V core voltage and 3.3 V I/O voltage, with internal voltage regulation for core supply stability.

Key Specifications

Pinout & Package

XC2S150-5FGG256C is housed in a 256-ball Fine-Pitch Ball Grid Array (FBGA) package with 1.0 mm ball pitch, 17 mm × 17 mm body size, and thermal pad exposed on underside for enhanced heat dissipation.

Equivalent & Alternatives

The following parts are listed as comparable options for similar FPGA logic implementation applications.

Compared with XC2S150-5PQ208C, the XC2S150-5FGG256C offers higher I/O density and superior thermal performance; compared with XC3S200-4PQ208C, it requires legacy ISE 6.x tool support and lacks dedicated DSP slices, making it appropriate for cost-sensitive, mature-design maintenance rather than new high-performance logic development.

Availability

XC2S150-5FGG256C is available at Aetrix Electronics and suitable for industrial motion control, digital video interface bridging, and PCI bus interface adapter applications requiring stable component supply across extended product lifecycles.

Supply support for XC2S150-5FGG256C includes scheduled delivery planning, volume procurement assistance, BOM continuity management, traceable sourcing, and lifecycle availability coordination for OEM customers, industrial embedded developers, connected-device designers, and electronics production programs.

Manufacturer

AMD acquired Xilinx in 2022 and maintains legacy Spartan-II product support, documentation, and long-term supply commitments for industrial and aerospace customers.

The Spartan-II family was designed for cost-sensitive, high-volume applications requiring moderate logic density, fast I/O, and in-system programmability - especially in industrial automation and communications infrastructure.

FAQ

What is the maximum operating frequency supported by XC2S150-5FGG256C?

The XC2S150-5FGG256C has a -5 speed grade specifying a 5 ns CLB propagation delay, enabling typical system clock frequencies up to 160 MHz in well-constrained designs. Actual achievable frequency depends on logic depth, routing congestion, and I/O timing closure. Static timing analysis in Xilinx ISE 6.3 must confirm timing for each specific implementation.

Does XC2S150-5FGG256C support JTAG boundary-scan testing?

Yes, XC2S150-5FGG256C fully complies with IEEE 1149.1 JTAG boundary-scan standard. Pins TCK, TMS, TDI, and TDO (balls W14, V14, U14, T14) provide access for programming, debugging, and interconnect testing without requiring additional test fixtures or probes.

What power supply voltages does XC2S150-5FGG256C require?

XC2S150-5FGG256C requires two separate supplies: 2.5 V ± 0.1 V for the core logic (VCCINT), and 3.3 V for I/O banks (VCCO). An auxiliary 2.5 V supply (VCCAUX) powers configuration and JTAG circuitry. Each supply must be locally decoupled with low-ESR capacitors near the FBGA corners.

Can XC2S150-5FGG256C be configured using a serial PROM?

Yes, XC2S150-5FGG256C supports master serial configuration mode using industry-standard Xilinx-compatible PROMs (e.g., XCF02S, XCF04S). Configuration occurs automatically on power-up when M0 and M1 pins are set to 01, loading the bitstream from the PROM into SRAM-based configuration memory.

Is XC2S150-5FGG256C still in active production?

XC2S150-5FGG256C is in long-term, controlled-lifecycle status under AMD's legacy product support program. While no longer in high-volume wafer fabrication, Aetrix Electronics maintains verified inventory and authorized channel supply with full traceability and extended availability assurance for industrial and defense customers.
