Product details
Overview
XC2S100E-6PQ208C from Xilinx is a second-generation Spartan-IIE Field-Programmable Gate Array with 2,700 logic cells, 600 CLBs (20 × 30 array), 40 Kbits of block RAM, and four Delay-Locked Loops (DLLs) for clock management. It operates at 1.8 V core voltage and supports 3.3 V/2.5 V/1.5 V I/O standards, targeting high-volume embedded control and interface bridging applications.
For engineers reviewing the XC2S100E-6PQ208C datasheet, pinout, applications, or equivalent options, this page delivers verified architecture details, I/O banking constraints, DLL timing parameters, CLB switching characteristics, and package-specific user I/O allocation for PQ208.
Technical Context
The XC2S100E-6PQ208C implements a regular FPGA architecture with Configurable Logic Blocks (CLBs) arranged in a 20 × 30 array, surrounded by programmable Input/Output Blocks (IOBs) grouped into eight independent I/O banks. Each CLB contains four logic cells with 4-input LUTs, dedicated carry logic, and dual flip-flops per slice.
It integrates four corner-placed DLLs supporting clock multiplication, division, and phase shifting; 40 Kbits of true dual-port block RAM; and distributed RAM via LUTs (38,400 bits). The device uses 0.15 µm CMOS technology, with core powered at 1.8 V and I/Os configurable across 19 standards including LVTTL, LVCMOS, HSTL, SSTL, LVDS, and PCI-compliant interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Cells | 2,700 - defines total combinational and sequential logic capacity for custom digital logic implementation |
| System Gate Range | 37,000–100,000 - indicates scalable logic density suitable for mid-complexity control and protocol logic |
| CLB Array | 20 × 30 - determines routing flexibility and maximum parallel logic depth in the fabric |
| Block RAM | 40 Kbits - provides on-chip synchronous dual-port memory for FIFOs, buffers, or lookup tables |
| User I/O Pins | 182 - number of configurable I/Os available in PQ208 package, including four global clock pins |
| DLLs | 4 - enables precise clock deskew, frequency synthesis, and multi-domain timing control without external PLLs |
| Max Differential I/O Pairs | 86 - supports high-speed point-to-point links such as LVDS-based sensor interfaces or display data paths |
| Speed Grade | -6 - guarantees timing closure up to 166 MHz system clock frequency under commercial temperature conditions |
Pinout & Package
XC2S100E-6PQ208C is housed in a 208-pin Plastic Quad Flat Package (PQFP) with 0.5 mm pitch, compliant with JEDEC MS-026. The package supports eight independent I/O banks, each with dedicated VCCO and VREF pins; in PQ208, all VCCO pins are internally interconnected, permitting only one I/O voltage level across the entire device.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GCLK0–GCLK3 | Global Clock Input | Four dedicated low-skew clock inputs routed to all DLLs and CLBs; essential for synchronous domain partitioning |
| PROGRAM_B | Configuration Initiate | Active-low signal that resets configuration logic and clears internal SRAM; must be pulled high for normal operation |
| DONE | Configuration Status | Open-drain output indicating successful bitstream loading; drives high after CRC check and initialization completion |
| TCK/TMS/TDI/TDO | JTAG Boundary Scan | IEEE 1149.1-compliant test interface for programming, debugging, and interconnect verification |
| VCCINT | Core Power Supply | 1.8 V supply for internal logic and CLBs; requires tight regulation and local decoupling near package corners |
| VCCO_0–VCCO_7 | I/O Bank Power | In PQ208, all VCCO pins tied together - mandates single 1.5 V / 2.5 V / 3.3 V I/O voltage for full device |
| IO_LxxN/IO_LxxP | Differential I/O Pair | LVDS-compatible complementary pair; supports 312 Mbps data rate with internal termination when enabled |
Key Features
| Feature | Design Value |
|---|---|
| SelectRAM™ Hierarchical Memory | Combines 40 Kbits block RAM + 38,400 bits distributed RAM (via LUTs) for flexible memory mapping in control and buffering tasks |
| Four Dedicated DLLs | Eliminates clock skew across die; enables 0° phase alignment, 2×/4× multiplication, and jitter-tolerant clock recovery |
| Eight I/O Banks with VCCO/VREF Isolation | Allows mixed-voltage signaling within same package (e.g., 3.3 V LVTTL and 2.5 V SSTL) when using compatible packages like FT256 |
| Hot-Swap Support | Enables safe insertion into live CompactPCI backplanes; IO pins remain high-Z until configuration completes |
| PCI 3.3 V Compliance | Meets PCI Local Bus Specification v2.2 at 66 MHz; supports direct attachment to legacy host bridges without level shifters |
| Unlimited In-System Reprogrammability | Configuration stored in SRAM; updated via JTAG, slave serial, or master serial PROM - no field hardware change required |

Equivalent & Alternatives
The following parts are listed as comparable options for similar FPGA-based logic implementation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| XC2S100E-6TQ144C | Same logic resources and speed grade, but in 144-pin TQFP with only 102 user I/Os and no differential I/O support | Suitable for space-constrained designs where I/O count and LVDS are not required | Select when PCB area is critical and interface complexity is low; verify thermal derating for same power dissipation in smaller package |
| XC3S1000-4PQ208C | Third-generation Spartan-3 device with 1M system gates, 17,280 logic cells, and enhanced SelectIO support (including SSTL18) | Better suited for higher-bandwidth protocols (e.g., DDR SDRAM controller) requiring more logic and memory | Choose for new designs needing scalability beyond Spartan-IIE; note incompatible bitstream format and different configuration sequence |
Compared with XC2S100E-6PQ208C, the XC2S100E-6TQ144C reduces I/O count and eliminates differential signaling capability, while the XC3S1000-4PQ208C offers significantly greater logic density and modern I/O standards but requires full toolchain and design migration.

FAQ
What is the maximum operating frequency supported by XC2S100E-6PQ208C?
The XC2S100E-6PQ208C has a -6 speed grade, guaranteeing timing closure up to 166 MHz for system clock domains under commercial temperature conditions (0°C to +85°C). This rating is validated across CLB switching, DLL output jitter, and I/O setup/hold margins per DS077-3 specifications.
Does XC2S100E-6PQ208C support hot-swap functionality?
Yes, XC2S100E-6PQ208C supports hot-swap per CompactPCI v2.2 requirements. Its I/O pins remain high-impedance during power-up and configuration, with no current path to VCCINT or VCCO. This allows safe insertion into powered backplanes without risk of latch-up or system disruption.
How many differential I/O pairs are available on XC2S100E-6PQ208C?
XC2S100E-6PQ208C supports up to 86 differential I/O pairs in the PQ208 package. These are implemented as LVDS- or Bus LVDS-capable IO_LxxN/IO_LxxP pin pairs, each configurable for input, output, or bidirectional use with internal 100 Ω termination.
What I/O voltage levels does XC2S100E-6PQ208C support?
XC2S100E-6PQ208C supports 1.5 V, 2.5 V, and 3.3 V I/O standards. In the PQ208 package, all VCCO pins are internally connected, so only one I/O voltage can be used across the entire device - unlike larger packages (e.g., FT256) which support independent bank voltages.
Is XC2S100E-6PQ208C still in production?
No - XC2S100E-6PQ208C was discontinued per Xilinx Change Notice XCN12026 (2012). However, Aetrix Electronics maintains traceable inventory and offers lifecycle management support, including cross-reference guidance and obsolescence mitigation planning for legacy systems.
