Product details
Overview
XC4044XL-3HQ240I from Xilinx is a Field-Programmable Gate Array (FPGA) with 44,000 usable gates, 240-pin PQFP package, -3 speed grade, and industrial temperature range (-40°C to +100°C); used in high-reliability embedded control and digital signal processing systems.
For engineers reviewing the XC4044XL-3HQ240I datasheet, pinout, applications, or equivalent options, key selection considerations include gate count, I/O count (192 user I/Os), speed grade timing performance, industrial temperature rating, and legacy 5V CMOS compatibility.
Technical Context
The XC4044XL-3HQ240I implements configurable logic blocks (CLBs) and I/O blocks (IOBs) with dedicated carry logic for arithmetic functions; supports SRAM-based configuration with external PROM or microprocessor loading. It uses 5V supply voltage and TTL/CMOS-compatible I/O standards.
It features internal three-state bus management, global clock routing, and programmable output slew rate control; no on-chip PLL or dedicated memory blocks - configuration and operation rely on external support circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gates | 44,000 usable system gates - defines maximum combinational logic capacity for custom digital design implementation |
| Package | 240-pin Plastic Quad Flat Pack (PQFP) - surface-mount, 28 × 28 mm footprint with 0.5 mm pitch, suitable for industrial PCB assembly |
| Speed Grade | -3 - guarantees maximum clock frequency of 125 MHz for CLB-to-CLB paths under industrial conditions |
| I/O Count | 192 user-programmable I/O pins - supports parallel bus interfaces, address/data multiplexing, and multi-signal control routing |
| Supply Voltage | 5.0 V ± 5% - requires standard 5V regulator; not compatible with 3.3V or mixed-voltage I/O domains |
| Operating Temp | -40°C to +100°C - qualified for extended industrial environments without derating |
Pinout & Package
XC4044XL-3HQ240I is housed in a 240-pin PQFP (Plastic Quad Flat Package) with 60 pins per side, 0.5 mm lead pitch, and exposed thermal pad not present. Pin functions are defined by configuration bitstream and IOB programming.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GCLK1–GCLK4 | Global Clock Inputs | Dedicated low-skew routing to all CLBs; essential for synchronous system timing integrity |
| PROGRAM | Configuration Reset | Active-low input that clears configuration RAM and forces reinitialization from external PROM |
| DIN | Serial Configuration Data In | Primary serial interface for loading configuration bitstream from external PROM or processor |
| INIT | Configuration Status | Open-drain output indicating successful configuration completion or error condition |
| VCCINT / VCCO | Core & I/O Power | Separate 5V supplies: VCCINT powers logic core; VCCO powers I/O buffers (single 5V rail required) |
Key Features
| Feature | Design Value |
|---|---|
| SRAM-based configuration | Enables in-system reprogrammability via JTAG or serial PROM; no one-time-programming limitation |
| Three-state bus control | Integrated output enable logic per I/O allows direct connection to shared data/address buses without external transceivers |
| Global clock network | Four dedicated low-jitter clock inputs with fanout to all CLBs - reduces skew in large synchronous designs |
| Programmable slew rate | Selectable fast/normal/slow output edge rates per I/O - mitigates EMI and signal integrity issues on dense PCBs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar FPGA-based digital logic implementation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| XC4044XL-2HQ240I | Faster -2 speed grade (133 MHz CLB-to-CLB), identical gate count, package, and I/O count | Better suited for higher-frequency control loops or tighter timing margins; same PCB layout | Select when timing closure requires >125 MHz performance without changing board or firmware |
| XC4036XL-3HQ240I | Lower density: 36,000 gates, otherwise identical speed grade, package, voltage, and temperature rating | Appropriate for cost-optimized or lower-complexity designs where full 44K gate capacity is unused | Choose to reduce unit cost while retaining pinout, thermal profile, and system integration compatibility |
Compared with XC4044XL-3HQ240I, the -2 speed grade alternative enables higher clock rates in timing-critical paths, while the XC4036XL-3HQ240I offers gate reduction without layout or thermal redesign - both preserve 5V operation and industrial qualification.

The XC4044XL-3HQ240I has a -3 speed grade specifying a maximum CLB-to-CLB propagation delay of 3.0 ns, enabling reliable operation up to 125 MHz in synchronous logic paths. Actual system clock frequency depends on design topology, routing, and I/O timing constraints - the XC4044XL-3HQ240I datasheet provides detailed timing models for static analysis.
Does XC4044XL-3HQ240I support JTAG boundary-scan testing?
Yes, XC4044XL-3HQ240I includes IEEE 1149.1-compliant JTAG TAP controller for boundary-scan testing, configuration, and debug. Pins TDI, TDO, TMS, and TCK are dedicated for this function and operate at 5V logic levels - the XC4044XL-3HQ240I supports INTEST and SAMPLE/PRELOAD instructions per JTAG standard.
Can XC4044XL-3HQ240I be reconfigured in-system after power-up?
Yes, XC4044XL-3HQ240I uses SRAM-based configuration memory and supports in-system reprogramming via serial PROM, microprocessor interface, or JTAG. The PROGRAM pin initiates configuration reload without power cycle, and INIT confirms successful bitstream loading - XC4044XL-3HQ240I retains full reconfigurability throughout its operational life.
What are the power supply requirements for XC4044XL-3HQ240I?
XC4044XL-3HQ240I requires a single 5.0 V ± 5% supply for both core (VCCINT) and I/O (VCCO) rails. Total current draw depends on toggle rate and I/O loading but typically ranges from 300 mA to 900 mA under active operation. Decoupling capacitors (0.1 µF ceramic per power pin) are mandatory per XC4044XL-3HQ240I layout guidelines.
Is XC4044XL-3HQ240I RoHS compliant?
No, XC4044XL-3HQ240I is a legacy device manufactured prior to RoHS Directive enforcement and contains leaded solder in its 240-pin PQFP package. It is exempt from RoHS under Annex III for industrial monitoring and control equipment - XC4044XL-3HQ240I remains available for legacy system repair and long-life program support.
