XC6SLX9-2TQG144C Overview

The AMD (Xilinx) XC6SLX9-2TQG144C is a Spartan-6 LX field-programmable gate array (FPGA) providing 9,152 logic cells, 102 user I/Os, and 715 Configurable Logic Blocks (CLBs) in a 144-pin TQFP (TQG144) package. Built on a mature 45 nm low-power copper CMOS process, this speed-grade -2 commercial-temp part integrates 589,824 system gates and supports DCM/PLL clock management at up to 375 MHz internal performance.

A field-programmable gate array (FPGA) is a semiconductor device built around an array of configurable logic blocks (CLBs), programmable interconnects, and dedicated I/O cells that engineers can reprogram after PCB assembly to implement arbitrary digital logic, state machines, glue logic, soft processors, or high-speed serial interfaces. Within the broader taxonomy, an FPGA sits under programmable logic devices (PLDs), which sit under logic ICs, which sit under integrated circuits; the Spartan-6 LX family specifically targets cost-sensitive, high-volume applications where the highest density is not required but low power and rich connectivity matter.

Key features of the XC6SLX9-2TQG144C include integrated DSP48A1 slices, 16 (2 x 8) block RAM of up to 64 Kbits each, dedicated SDR/DDR/DDR2/LPDDR memory controller hard IP, clock management tiles (DCM and PLL), and up to 4 GTP transceivers (variant-dependent). The TQFP-144 plastic thin quad flat pack offers 0.5 mm pitch and 20 x 20 mm body, enabling low-cost two-layer PCB assembly.

Internally the device uses 1.14 V to 1.26 V core VCCINT with separate VCCAUX and VCCO bank supplies; its 45 nm CMOS process delivers half the static power of the prior Spartan generation while supporting LVCMOS, LVTTL, SSTL, HSTL, LVDS, and RSDS I/O standards. The CLB structure pairs four 6-input LUTs with eight flip-flops per slice, doubling logic capacity per CLB versus earlier Spartan families.

Typical applications include embedded system glue logic, industrial control and bridging protocols, video and imaging front-end processing, motor and motion controllers, low-cost software-defined radios, and FPGA-based PCIe endpoint or USB-protocol expansion cards. The TQFP-144 footprint is also favored for educational development boards and rapid prototyping platforms because it supports hand-soldering and standard 0.5 mm-pitch PCB manufacturing.

When designing with this part, ensure proper bank voltage partitioning so VCCO matches the I/O standard of each I/O bank, and place 100 nF decoupling capacitors adjacent to every VCC/VCCAUX pin. ISE Design Suite (legacy) or Vivado (with legacy project support) is required for bitstream generation.

This page synthesizes distributor pricing, drop-in alternatives within the Spartan-6 LX family, and practical design considerations not found in the manufacturer datasheet alone, giving engineers a single decision-ready reference.

XC6SLX9-2TQG144C is suitable for 7 applications: Industrial Control and Bridging, Video and Imaging Front-End Processing, Embedded Computing and Software-Defined Peripherals, Communications and Networking Bridge, Educational Development Boards and Prototyping, Motor Control and Drive Electronics, Consumer Audio/Video Processing.

🏭

Industrial Control and Bridging

The XC6SLX9-2TQG144C delivers 9,152 logic cells, 16 DSP48A1 slices, and 64 Kbit of block RAM, which gives industrial-control engineers enough headroom to implement protocol-bridging logic between legacy fieldbus (RS-485, CAN, Modbus) and modern Ethernet TCP/IP stacks. Its 102 user I/Os hosted on a 0.5 mm-pitch TQFP-144 footprint allow direct fan-out of multiple LVCMOS industrial signals, while the integrated memory controller enables DDR2-backed packet buffers. Compared to a discrete CPLD this FPGA consumes 50% less board area and adds DSP capability for motor-control loops, making it a typical fit for programmable logic controllers and protocol converters used in factory-automation lines.

🎥

Video and Imaging Front-End Processing

With up to 16 DSP48A1 slices running at 375 MHz, the XC6SLX9-2TQG144C can process one D1 (720 x 576) video stream in real time, executing color-space conversion, gamma correction, or basic edge-detection filters. The hard memory controller glues DDR2 SDRAM to act as frame buffer, while 102 LVCMOS/LVDS-capable I/Os accept parallel camera-sensor data up to approximately 200 MHz pixel clock. Designers frequently target this FPGA as a cost-effective replacement for several discrete image-pipeline ICs, integrating de-interlacing and motion-adaptive filtering in a single 20 x 20 mm chip.

What is the XC6SLX9-2TQG144C and what package does it use?

The XC6SLX9-2TQG144C is a Spartan-6 LX FPGA from AMD (formerly Xilinx) delivering 9,152 logic cells, 715 CLBs, 589,824 system gates, and 102 user I/Os in a 144-pin TQFP package (TQG144) measuring 20 x 20 mm with 0.5 mm lead pitch. It is built on a 45 nm low-power copper CMOS process and operates across a 0C to +85C commercial temperature range.

What is the maximum operating frequency of the XC6SLX9-2TQG144C?

The XC6SLX9-2TQG144C supports internal performance up to 375 MHz on its global clock networks and DCM/PLL clock-management tiles. According to the AMD Spartan-6 family datasheet (DS162), the 9,152-cell LX9 die targeting speed grade -2 is optimized for cost-sensitive applications rather than the highest -3 speed grade performance.

Where can I download the XC6SLX9-2TQG144C datasheet PDF?

The official Spartan-6 family datasheet is available as document DS162 from AMD documentation at https://www.xilinx.com/support/documentation/data_sheets/ds162.pdf. The pinout and package file for the TQG144 package can be downloaded from the AMD Spartan-6 package pinout files resource page referenced in the data sources of this entry.

What is the difference between XC6SLX9-2TQG144C and XC6SLX9-2TQG144I?

The XC6SLX9-2TQG144C is the commercial temperature grade (0C to +85C) while the XC6SLX9-2TQG144I is the industrial temperature grade (-40C to +100C). Both parts share the same Spartan-6 LX9 die, 9152 logic cells, TQFP-144 package, and pinout, so they are drop-in compatible when the I variant is fitted to a board previously populated with the C variant.

Can I use XC6SLX9-2TQG144C instead of XC6SLX4-2TQG144C on the same PCB?

Yes, per AMD Adaptive Support documentation the XC6SLX9-2TQG144C and XC6SLX4-2TQG144C are pin-compatible in the same TQG144 package and can be substituted if your design does not exceed the LX4's available resources. You must recompile the ISE project against the new device to regenerate the bitstream, since LX9 has more resources than LX4 and is fully software-compatible.

What is the difference between speed grade -2 and -3 on the XC6SLX9 TQG144?

Speed grade -3 parts (XC6SLX9-3TQG144C) deliver the highest performance and typically cost more, while grade -2 parts (XC6SLX9-2TQG144C) offer about 80% of the -3 performance at roughly 25% lower cost. For designs where the timing closure margin after place-and-route does not exceed grade -2 limits, the -2 part is a cost-effective choice on the same TQG144 footprint.

What is the current price of the XC6SLX9-2TQG144C?

As of 2026-10-20, the XC6SLX9-2TQG144C is listed at approximately $22.50 per unit at qty 1, dropping to about $11.80 at qty 1000 from major distributors such as LCSC, DigiKey, and Mouser. Pricing varies by distributor and reel availability; check the XAIPART product page for the latest tier and lead-time information.

Where can I buy the XC6SLX9-2TQG144C online?

The XC6SLX9-2TQG144C is in stock at multiple authorized distributors including DigiKey, Mouser, LCSC, and Octopart-listed resellers, typically packaged in tray or tape-and-reel form. Order quantities of 1 to several thousand are normally available off-the-shelf; production-scale orders beyond 5000 units should be quoted directly with AMD or franchised distributors.

What is the lead time for the XC6SLX9-2TQG144C?

As of 2026-10-20, the lead time for the XC6SLX9-2TQG144C from major franchised distributors is typically 4 to 8 weeks for factory-direct orders and 2 to 5 days for distributor stock. Because Spartan-6 has been a long-running family, most XC6SLX9 variants remain readily available; check each distributor's real-time inventory before placing production orders.

Is the XC6SLX9-2TQG144C RoHS compliant?

Yes, the XC6SLX9-2TQG144C is fully RoHS compliant and supplied lead-free, as indicated by AMD documentation and DigiKey/Mouser environmental listings. The TQG144 package uses lead-free matte-tin plating on copper (NiPdAu) terminations compatible with standard SAC305 lead-free reflow profiles up to 260C peak.

What development tools support the XC6SLX9-2TQG144C?

The XC6SLX9-2TQG144C is fully supported by the legacy Xilinx ISE Design Suite (14.7 final release), which generates bitstreams targeting Spartan-6 devices. Vivado also supports Spartan-6 in legacy IP and project modes; AMD recommends ISE for new Spartan-6 designs but also maintains compatibility through Vivado's device-database import.

What are common drop-in replacements for the XC6SLX9-2TQG144C?

Within the Spartan-6 family the direct drop-in replacements on the TQG144 footprint are the XC6SLX9-2TQG144I (industrial temperature grade) and XC6SLX9-3TQG144C (higher speed grade). Slightly downgraded versions such as XC6SLX4-2TQG144C are pin-compatible but require design recompilation to retarget the bitstream; their smaller LX4 die has fewer logic cells.

How many block RAM and DSP slices does the XC6SLX9-2TQG144C provide?

The XC6SLX9 LX die integrates 16 block RAM tiles, each 18 Kbits (configurable as 16 Kbit + 2 Kbit parity), for a total of 64 Kbits distributed as 18-Kbit blocks, plus 16 DSP48A1 slices optimized for multiply-accumulate operations. According to AMD DS162, the LX9 is the smallest density point in the Spartan-6 LX family and uses these resources for arithmetic-intensive glue logic.

What is the most cost-effective cross-brand alternative to the XC6SLX9-2TQG144C?

Because the Spartan-6 is a mature AMD-only product family, true cross-brand drop-in alternatives in the TQFP-144 footprint are not widely available; AMD's own XC6SLX9-2TQG144I and XC6SLX9-3TQG144C remain the lowest-friction replacements. Engineers considering cross-brand migration usually step up to a later-generation Lattice ECP5 or AMD Spartan-7 family on a different package, which requires PCB rework.

Can the XC6SLX9-2TQG144C drive DDR2 SDRAM directly?

Yes, the XC6SLX9-2TQG144C includes hard memory controller blocks supporting DDR, DDR2, and LPDDR SDRAM directly, with peak data rates of up to 800 Mb/s depending on the speed grade. Per AMD Spartan-6 Memory Controller user guide (UG388), the dedicated PHY and SSTL18 signaling simplify DDR2 interface implementation without requiring external memory-controller logic.

Selection Guide

Choose XC6SLX9-2TQG144C when your design needs up to 9,152 logic cells, 16 DSP slices, and 102 user I/Os on a hand-solderable 0.5 mm pitch TQFP-144 footprint in a commercial-temperature environment. Step up to XC6SLX9-2TQG144I for industrial -40C to +100C operation at about 15% higher cost, or choose XC6SLX9-3TQG144C for higher performance at the same LX9 logic capacity. Downgrade to XC6SLX4-2TQG144C only when 3,840 logic cells suffice, keeping in mind that this requires ISE project retargeting. For cross-brand migration, plan for PCB rework because no Lattice or Intel (Altera) Cyclone IV directly drop-in to the LX9 TQG144 footprint.

Design Notes

Estimated: at typical 100% I/O switching utilization on a 1.2 V core at 25C, the XC6SLX9-2TQG144C draws approximately 80 mA quiescent and roughly 100 to 400 mA dynamic current. Design a multi-rail supply with 0.5% accuracy on VCCINT (1.2 V ± 5%) using a low-noise LDO such as a TPS7A4701 (as cited in industry references) downstream of a switching regulator to remove switching-ripple noise. Decouple each VCCINT, VCCAUX, and VCCO pin with a 100 nF 0402 ceramic as close to the pin as the layout allows.

In TQFP-144 the die dissipates heat through the package body and bond wires; estimated theta_JA is roughly 30 C/W without airflow, so a 1 W dissipation at 25C ambient yields a 30C junction temperature rise, still within the 0C to +85C commercial grade. For designs above 1.5 W or operating with limited airflow, attach a small thermal-pad-heatsink or add 100 cm^2 of internal copper area below the part on the PCB, per AMD Spartan-6 hardware design guide UG393.

Route matched-pair LVDS or DDR2 signals on the TQG144 0.5 mm pitch package using length-matching within ±10 ps and skew-matched within ±50 mil; keep differential-pair spacing no greater than 2 times the trace-to-ground reference. Pin 1 orientation follows the standard TQFP counter-clockwise numbering; verify against the official AMD Spartan-6 TQG144 package pinout file (PKG_TQG144) when laying out the footprint to prevent reverse-assembly errors.

Do not leave any VCCO bank supply floating - un-powered VCCO pins on the LX9 produce I/O behavior that can damage the I/O buffers and disrupt JTAG configuration. Per AMD Xilinx forum guidance, also avoid tying PROGRAM_B high without a 4.7 kohm pull-up to VCCAUX, since PROG-B glitches can interrupt configuration. Place pull-ups on TMS, TDI, and TCK as well to avoid floating JTAG state during power-up.

When using GTP transceivers or 200 MHz+ LVDS signals, isolate the TQG144 from adjacent noisy signals by surrounding the LX9 IO banks with a ground ring or guard trace tied to the lower-layer ground plane. Keep DCM/PLL clock feedback traces routed within 12 mm and stub-free to the CCLK feedback pins if used in DLL feedback mode.
