Product details
Overview
XC2S300E-6PQG208C from Xilinx is a Spartan®-IIE Field-Programmable Gate Array with 6,912 logic cells, 329 user I/Os, and four Delay-Locked Loops (DLLs), operating at 1.8V core voltage and supporting 3.3V/2.5V/1.8V I/O standards. It delivers up to 300,000 system gates and targets high-volume embedded control, industrial interface bridging, and legacy bus protocol adaptation.
For engineers reviewing the XC2S300E-6PQG208C datasheet, pinout, applications, or equivalent options, key selection criteria include DLL-based clock deskew for synchronous I/O timing, hot-swap-capable I/O banks compliant with CompactPCI v2.2, and dual-port block RAM for FIFO buffering in real-time data acquisition systems.
Technical Context
The XC2S300E-6PQG208C implements a hierarchical architecture with Configurable Logic Blocks (CLBs) containing four logic cells each, distributed 16×1-bit LUT RAM, and dedicated carry chains for arithmetic acceleration. Its four corner-placed DLLs provide zero-delay clock distribution, phase shifting, and frequency multiplication - critical for PCI 66 MHz compliance and LVDS source-synchronous interfaces.
I/O functionality is organized into eight independent voltage-banked IOBs, each supporting 19 selectable standards including LVTTL, LVCMOS, SSTL, HSTL, and LVDS. The PQG208 package enables 182 user I/Os with VCCO shared across all banks, requiring single-supply I/O configuration while permitting per-bank VREF assignment for mixed-input thresholds.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Cells | 6,912 - defines maximum combinational and sequential logic capacity for custom digital state machines or protocol engines |
| User I/O Count | 182 - number of configurable bidirectional pins available in PQG208 package, excluding dedicated global clocks |
| Block RAM | 64 Kbits - implemented as sixteen 4K-bit true dual-port RAM blocks, enabling simultaneous read/write for buffering or lookup tables |
| DLLs | 4 - corner-located delay-locked loops for eliminating clock skew, generating phase-aligned clocks, and meeting setup/hold timing in high-speed interfaces |
| Core Voltage (VCCINT) | 1.8 V - determines static power consumption and thermal profile; requires low-noise regulation and decoupling near die center |
| I/O Voltage (VCCO) | 3.3 V / 2.5 V / 1.8 V - selectable per bank; sets output drive strength, input threshold, and compatibility with external memory or bus transceivers |
| Max System Gates | 300,000 - aggregate logic density metric derived from CLB count and routing resources, used for ASIC replacement cost estimation |
Pinout & Package
PQG208 is a 208-pin Plastic Quad Flat Package with Gull-wing leads, RoHS-compliant (Pb-free), 28 × 28 mm body size, and 0.5 mm pitch. Pin assignments follow JEDEC MO-137AC standard with corner-indexed pin 1 marker.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GCLK0–GCLK3 | Global Clock Input | Four dedicated low-skew clock inputs routed directly to DLLs; required for synchronous domain partitioning and jitter-sensitive timing paths |
| PROGRAM_B | Configuration Initiate | Active-low asynchronous reset that clears configuration memory and forces reinitialization from external PROM or host controller |
| DONE | Configuration Status | Open-drain output indicating successful bitstream loading; must be pulled up externally to enable subsequent device operation |
| TCK/TMS/TDI/TDO | JTAG Boundary Scan | IEEE 1149.1-compliant test interface for in-circuit verification, programming, and debug access without dedicated programming hardware |
| VCCINT | Core Power Supply | 1.8 V supply for internal logic and CLBs; requires local ceramic decoupling and separate plane from I/O supplies to minimize noise coupling |
| VCCO_0–VCCO_7 | I/O Bank Power | Eight VCCO pins - one per I/O bank - must be tied to same voltage within each bank; in PQG208, all are internally connected to single VCCO net |
Key Features
| Feature | Design Value |
|---|---|
| Hot-swap I/O capability | Enables safe insertion into powered CompactPCI backplanes without latch-up risk or system disruption; verified per PCI Bus v2.2 specification |
| SelectRAM™ hierarchical memory | Combines 98,304 bits of distributed LUT RAM (16×1-bit per LUT) with 64 Kbits of true dual-port block RAM for flexible on-chip data storage and buffering |
| Four DLLs with phase shift | Provides deterministic clock deskew, 0°–360° programmable phase adjustment, and integer frequency multiplication (×2, ×4) for precise timing alignment |
| 19 I/O standards support | Includes LVTTL, LVCMOS, SSTL, HSTL, LVDS, and GTL+ - allowing direct interfacing to DDR SDRAM, PCI, and differential serial links without level-shifting ICs |
| Unlimited in-system reprogrammability | Configuration stored in SRAM allows full functional updates via JTAG or serial PROM without physical replacement or soldering changes |

Equivalent & Alternatives
The following parts are listed as comparable options for similar FPGA logic and I/O applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| XC2S300E-6PQ208C | No "G" suffix - leaded (non-RoHS) package; identical electrical and functional specs | Same pinout and configuration interface; differs only in Pb-free compliance and moisture sensitivity level | Select when legacy assembly lines require SnPb solder compatibility or when RoHS exemption applies |
| XC3S200-4PQ208C | Spartan-3 generation; 5,292 logic cells, 289 I/Os, 180 Kbits block RAM, 1.2 V core | Higher density RAM and lower core voltage; lacks native LVDS but adds Digital Clock Manager (DCM) | Choose for new designs needing greater memory bandwidth or lower power; not drop-in due to different configuration scheme and DCM-based clocking |
Compared with XC2S300E-6PQG208C, the leaded XC2S300E-6PQ208C offers identical functionality with legacy solder process support, while the XC3S200-4PQ208C provides higher memory capacity and lower core voltage at the cost of non-compatible configuration and clock management architecture.
