Product details
Overview
XC4044XLA-09HQ208C from Xilinx is a high-capacity, 3.3 V Field-Programmable Gate Array (FPGA) featuring 3,800 logic cells, 44,000 typical usable gates, 51,200 RAM bits, and 320 user I/Os in a 208-pin HQFP package. It supports synchronous system clock rates up to 80 MHz, includes edge-triggered and dual-port SelectRAM™ memory per CLB, and delivers PCI compliance for -2 and faster speed grades - used in legacy telecom line cards and industrial control backplanes.
For engineers reviewing the XC4044XLA-09HQ208C datasheet, pinout, applications, or equivalent options, key selection criteria include confirmed CLB count (1,600), I/O count (320), 0.35 µm SRAM process node, 3.3 V core voltage with 5 V-tolerant I/Os, and non-bitstream-compatible but pinout-compatible status versus XC4044XL.
Technical Context
The XC4044XLA-09HQ208C belongs to the XC4000XLA family - a low-voltage, high-performance variant of the XC4000X series built on 0.35 µm SRAM technology. It implements a regular array of 40×40 Configurable Logic Blocks (CLBs), each containing dual 4-input function generators (F/G), a third H-function generator, dual storage elements configurable as flip-flops (XC4000E/XL) or latches (XC4000X only), and dedicated carry logic.
Its routing architecture includes twenty-two additional vertical lines per CLB column and twelve new horizontal "Quad Lines" with optional repowering buffers. The device supports Master Parallel configuration with 22-bit addressing, Fast Capture latching for IOB input synchronization, and programmable IOB output MUX enabling dual-data sharing per pad - all while maintaining pin compatibility with XC4044XL but requiring recompilation of bitstreams.
Key Specifications

Key Features
| Feature | Design Value |
|---|---|
| SelectRAM™ Memory per CLB | Configurable as 16×2, 32×1, or 16×1 dual-port RAM - enables hardware FIFOs without external memory |
| Edge-Triggered Write Mode | Synchronous RAM writes aligned to CLB clock edge - eliminates external write strobe timing constraints |
| IOB Output MUX Capability | Per-pad multiplexer selects between data or clock-enable signal - doubles effective output count per pin |
| Fast Capture Latch in IOB | Early-clock-sampled input latch feeding main IOB flip-flop - reduces setup/hold violations on high-speed interfaces |
| 22-Bit Master Parallel Addressing | Supports daisy-chained configuration of large XC4000X devices - eliminates PROM address limitation of 18-bit XC4000E |
| Programmable Slew Rate | Per-output control of edge rate - mitigates ground bounce and EMI in dense PCB layouts |

Equivalent & Alternatives
The following parts are listed as comparable options for similar FPGA applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| XC4044XL-09HQ208C | Identical pinout and CLB count; differs in bitstream format and lacks XLA-specific low-power optimizations | Same footprint and I/O assignment; requires full recompilation due to architectural differences in routing and clock buffers | Preferred when migrating from legacy XC4044XL designs where board reuse is mandatory and power budget permits |
| XCV300-4PQ240C | Virtex-series successor with 300K system gates, 2.5 V core, and enhanced SelectRAM+ block RAM; not pin-compatible | Enables larger state machines and deeper buffers but requires PCB redesign and toolchain migration | Recommended for new designs needing >2× logic density, embedded multipliers, or higher clock rates beyond 100 MHz |
Compared with XC4044XL-09HQ208C, the XC4044XLA-09HQ208C offers identical I/O and CLB count but improved static power efficiency and tighter timing closure at 3.3 V; versus XCV300-4PQ240C, it trades raw capacity and advanced features for proven field reliability and minimal layout change in legacy systems.

FAQ
Is XC4044XLA-09HQ208C pin-compatible with XC4044XL-09HQ208C?
Yes, XC4044XLA-09HQ208C is pinout-compatible with XC4044XL-09HQ208C, sharing identical 208-pin HQFP mechanical dimensions, I/O assignments, and power/ground pin locations. However, XC4044XLA-09HQ208C requires recompilation of the bitstream due to architectural enhancements in routing and clock distribution - no PCB changes are needed, but configuration files are not interchangeable.
What is the maximum operating frequency of XC4044XLA-09HQ208C?
The XC4044XLA-09HQ208C supports synchronous system clock rates up to 80 MHz, validated for PCI-compliant operation at the -2 speed grade. Internal performance exceeds 150 MHz for critical paths, enabled by 0.35 µm SRAM process, dedicated carry logic, and low-skew global clock networks - actual achievable frequency depends on design placement and routing.
Does XC4044XLA-09HQ208C support dual-port RAM functionality?
Yes, XC4044XLA-09HQ208C supports dual-port RAM in every CLB: two 16×1 function generators can be jointly configured as a single 16×1 dual-port RAM with independent read and write ports. This enables simultaneous read/write operations to same or different addresses - essential for FIFOs, frame buffers, and ping-pong memory architectures.
Can XC4044XLA-09HQ208C interface directly with 5 V logic?
Yes, XC4044XLA-09HQ208C features 5 V-tolerant I/Os, allowing direct connection to 5 V TTL or CMOS peripherals without external level shifters. Its 3.3 V core voltage remains isolated, and I/O thresholds are configurable for either 3.3 V CMOS (1.6 V) or TTL-compatible levels - verified across industrial temperature range.
What configuration modes does XC4044XLA-09HQ208C support?
XC4044XLA-09HQ208C supports Master Serial, Slave Serial, Master Parallel, and Slave Parallel configuration modes. Master Parallel mode uses 22-bit addressing - an extension over XC4000E's 18-bit limit - enabling daisy-chained configuration of multiple large XC4000X devices from a single PROM.
