Product details
Overview
XC2S15-5VQG100I from AMD (formerly Xilinx) is a Spartan-II family FPGA with 15,000 system gates, 176 logic cells, 128 I/O pins, and 48 KB of block RAM. It operates at 5 V supply voltage with -5 speed grade (5 ns CLB delay), packaged in a 100-pin VQFP.
For engineers reviewing the XC2S15-5VQG100I datasheet, pinout, applications, or equivalent options, key selection factors include I/O count, gate density, VQFP package compatibility, 5 V tolerance, and legacy industrial control timing requirements.
Technical Context
The XC2S15-5VQG100I implements configurable logic blocks (CLBs) with four-input LUTs and flip-flops, distributed RAM, and dedicated carry logic for arithmetic. It supports SelectIO™ standards including LVTTL, LVCMOS, and PCI-compatible signaling on all I/O pins.
Configuration is performed via serial mode using an external PROM or parallel slave mode with a microprocessor. The device includes internal global clock buffers and DLL-based clock management for input deskew and phase alignment.
Key Specifications

| Block RAM | 48 KB total - organized as 192 × 256-bit blocks for FIFO, buffer, or lookup table use |
| Supply Voltage | 5.0 V ± 10% - enables direct interfacing with legacy 5 V TTL/CMOS systems without level shifters |
| Speed Grade | -5 (5 ns CLB propagation delay) - determines maximum operating frequency for critical path timing closure |
Pinout & Package
XC2S15-5VQG100I is housed in a 100-pin Very Thin Quad Flat Pack (VQFP), measuring 14 mm × 14 mm with 0.5 mm pitch. The package supports reflow soldering and provides full I/O access on all four sides.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCCO_0 | I/O bank power | Supplies 3.3 V or 5 V to Bank 0 I/Os - sets output voltage level and interface standard |
| GND | Ground reference | Common return path for core and I/O circuits - requires low-inductance connection to minimize noise |
| CLK0 | Global clock input | Dedicated low-skew input feeding internal clock network - used for synchronous design timing integrity |
| PROGRAM_B | Configuration reset | Active-low signal initiating FPGA reconfiguration from external PROM or host processor |
| TCK/TMS/TDI/TDO | JTAG boundary-scan interface | Enables IEEE 1149.1-compliant testing, programming, and debug without dedicated test fixtures |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar FPGA-based logic replacement applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| XC2S15-5TQG144C | 144-pin TQFP package, same logic capacity and speed grade but higher I/O count (112 vs. 128) | Requires PCB redesign due to different footprint and thermal profile | Choose only if additional I/O routing flexibility or thermal margin is required in new designs |
| XC3S50-4VQG100C | Spartan-3 family, 50,000 gates, 3.3 V core, no 5 V I/O tolerance | Not suitable for direct 5 V bus interfacing without external level translation | Consider for cost-sensitive upgrades where legacy 5 V interface is absent and higher density is needed |
Compared with XC2S15-5VQG100I, the XC2S15-5TQG144C offers more I/O pins in a larger package but identical logic performance, while the XC3S50-4VQG100C delivers greater gate density at lower power but mandates voltage translation for 5 V systems.

FAQ
What is the maximum operating frequency of the XC2S15-5VQG100I?
The XC2S15-5VQG100I has a -5 speed grade, specifying a 5 ns CLB propagation delay. This supports maximum system clock frequencies up to approximately 200 MHz for simple register-to-register paths. Actual achievable frequency depends on design topology, routing, and I/O constraints - verified through Xilinx ISE timing analysis for the XC2S15-5VQG100I.
Does the XC2S15-5VQG100I support in-system programming?
Yes, the XC2S15-5VQG100I supports in-system programming via its IEEE 1149.1 JTAG interface (TCK/TMS/TDI/TDO pins). Configuration bitstreams can be loaded dynamically through boundary-scan, enabling field updates and debugging without removing the XC2S15-5VQG100I from the board.
Can the XC2S15-5VQG100I operate with mixed I/O voltages?
Yes, the XC2S15-5VQG100I supports per-bank I/O voltage assignment. Each of its four I/O banks can be independently powered at either 3.3 V or 5 V, allowing simultaneous interfacing with both LVTTL and LVCMOS peripherals within a single XC2S15-5VQG100I design.
Is the XC2S15-5VQG100I RoHS compliant?
The XC2S15-5VQG100I is available in both RoHS-compliant (lead-free) and non-RoHS versions. The 'G' suffix in VQG100 indicates lead-free packaging. Always verify RoHS status using the full ordering part number and consult AMD/Xilinx documentation for the specific XC2S15-5VQG100I lot traceability.
What configuration modes does the XC2S15-5VQG100I support?
The XC2S15-5VQG100I supports Master Serial, Slave Serial, Slave Parallel, and JTAG configuration modes. External PROMs (e.g., XCF01S) are commonly used for Master Serial mode, while microprocessors typically drive Slave Parallel mode - all validated for the XC2S15-5VQG100I in Xilinx application notes.
