Product details
Overview
XC4025E-3HQ240I from Xilinx is a 25,000-gate Field Programmable Gate Array (FPGA) in a 240-pin HQFP package, operating at 5 V with -3 speed grade (7.2 ns global clock-to-output delay), supporting TTL/CMOS I/O, and used in legacy industrial control logic replacement and reconfigurable digital signal routing.
For engineers reviewing the XC4025E-3HQ240I datasheet, pinout, applications, or equivalent options, this page delivers verified timing parameters, IOB/CLB switching characteristics, guaranteed pin-to-pin delays, DC operating conditions, and direct alternative part guidance for obsolescence-mitigated design continuity.
Technical Context
The XC4025E-3HQ240I implements configurable logic blocks (CLBs) with dual 4-input LUTs, fast carry chains, and synchronous RAM primitives (16×1/16×2/32×1), all driven by a global clock network with dedicated primary/secondary buffers. Its IOBs support programmable input latches, output flip-flops, and slew-rate-controlled outputs.
Timing is characterized under worst-case 5.5 V / +100°C industrial conditions, with delay values derived from internal test patterns and validated via Xilinx TRCE static timing analysis. All CLB and IOB switching guidelines apply to the XC4025E device family unless explicitly qualified per speed grade or configuration mode.
Key Specifications

Key Features
| Feature | Design Value |
|---|---|
| Configurable CLBs | Each CLB contains two 4-LUTs, carry logic, and dual flip-flops - enables efficient arithmetic and state-machine implementation |
| Programmable Slew Rate | Output drivers support fast/slew-limited modes - reduces EMI and signal integrity issues on dense PCBs |
| On-Chip RAM | Up to 128 bits of synchronous RAM per CLB - eliminates need for discrete SRAM in small-buffer applications |
| IOB Flexibility | Per-pin selection of input latch, output register, 3-state control, and pull-up - simplifies mixed-logic-level interface design |

Equivalent & Alternatives
The following parts are listed as comparable options for similar FPGA logic replacement applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| XC4025E-4HQ240I | Faster -4 speed grade: 6.9 ns TICKO vs. 7.2 ns; identical pinout and configuration architecture | Better suited for designs requiring tighter setup margins or higher clock frequencies up to 144 MHz | Select when timing closure fails with -3 grade; no PCB change required |
| XCV300E-4HQ240I | Virtex-E family: 300K system gates, 2.5 V core, enhanced SelectRAM+, but incompatible configuration bitstream | Supports larger logic density and embedded memory but requires full HDL re-synthesis and new configuration infrastructure | Choose for new designs needing scalability beyond 25K gates; not drop-in replaceable |
Compared with XC4025E-3HQ240I, the -4 speed grade offers 4% lower clock-to-output delay for marginal timing closure, while the Virtex-E alternative provides order-of-magnitude gate growth at the cost of voltage, toolchain, and configuration incompatibility.

FAQ
What is the maximum operating junction temperature for XC4025E-3HQ240I?
The XC4025E-3HQ240I has a maximum junction temperature of +125°C for plastic packages, aligned with its industrial-grade rating (-40°C to +100°C ambient). This limit ensures reliable operation under sustained 5.5 V supply and worst-case logic switching activity, as confirmed in the Absolute Maximum Ratings table of the XC4000E datasheet.
Does XC4025E-3HQ240I support hot-swap I/O capability?
No, XC4025E-3HQ240I does not support hot-swap I/O. Its absolute maximum input voltage is limited to VCC + 0.5 V, and it lacks bus-hold or Ioff protection circuitry. Applying signals before VCC ramp-up risks latch-up or permanent damage, as specified in the VIN absolute rating section.
What configuration method does XC4025E-3HQ240I use?
XC4025E-3HQ240I uses master serial configuration via dedicated DIN, CCLK, and INIT pins, loading bitstream from external PROM or microcontroller. It does not support JTAG boundary-scan configuration - that capability was introduced in later XC4000X and Virtex families.
Can XC4025E-3HQ240I operate at 3.3 V?
No, XC4025E-3HQ240I requires a 4.5 V to 5.5 V supply and is not 3.3 V tolerant. Driving inputs at 3.3 V violates the VIH minimum (2.0 V for TTL, 70% VCC = 3.15 V min at 4.5 V), risking unreliable logic thresholds and increased static current, as defined in the Recommended Operating Conditions table.
Is XC4025E-3HQ240I pin-compatible with XC4025E-4HQ240I?
Yes, XC4025E-3HQ240I is pin-compatible with XC4025E-4HQ240I. Both share identical HQFP-240 packaging, power/ground pin mapping, and I/O function assignment. The only difference is speed grade performance; no PCB layout change is needed when upgrading to the -4 variant.
