XC3090L-8TQG176I अवलोकन

The Xilinx XC3090L-8TQG176I is a CMOS Field Programmable Gate Array from the legacy XC3000L low-voltage family, offering approximately 5000 usable gates (up to 9000 equivalent system gates) implemented across 320 Configurable Logic Blocks (CLBs) in a 176-pin TQG/LQFP package. It supports a maximum clock frequency of 80 MHz with a CLB combinatorial delay of 6.7 ns at the -8 speed grade, targeting high-density glue-logic, prototyping, and industrial control applications where ASIC-class integration is not yet justified.

What is an FPGA? A Field-Programmable Gate Array is a reconfigurable digital integrated circuit whose logic fabric and interconnect can be programmed by the end user after manufacture. Within the taxonomy of digital ICs, an FPGA sits between an Application-Specific Integrated Circuit (ASIC) and a microcontroller: an ASIC is hard-wired for one function but offers the lowest unit cost at high volume, while an FPGA trades per-unit cost for design flexibility, parallel hardware execution, and rapid time-to-market. The XC3000 family pioneered SRAM-based configuration and the now-universal island-style CLB + IOB + programmable interconnect architecture that defines the modern FPGA.

Key features of the XC3090L-8TQG176I include on-chip SRAM-based configuration store, three types of configurable elements (perimeter I/O Blocks, core CLB array, and routing channels), industrial-grade -40C to +85C operating range (I suffix), and the low-voltage L-suffix core that reduces 5V-family power. The device is housed in a 176-terminal LQFP/TQFP package on a 0.5 mm pitch with gull-wing leads suitable for surface-mount assembly and rework.

Technically, the XC3000L family uses a 5V-tolerant I/O structure with 3.3V or 5V core options, hierarchical interconnect including long lines, hex lines, and direct connects, and configurable IOBs that support registered, latched, or combinatorial I/O with tri-state control. The architecture integrates a configuration program store so the array can be re-programmed in-system via the standard Xilinx configuration interface.

Typical applications span industrial control systems, telecommunications glue logic, prototyping platforms for ASIC emulation, test and measurement fixtures, military/aerospace subsystems, and educational development kits where students learn HDL synthesis on a mature, well-documented device family. The TQG176 package is the highest-density option for this die.

When designing with the XC3090L-8TQG176I, note that this device family is mature (introduced in the early-to-mid 1990s), so verify long-term availability and second-source supply before committing new production designs. New designs should weigh migration to the Xilinx CoolRunner-II CPLD or Spartan-6/Spartan-7 FPGA families for active lifecycle status and modern toolchain support.

सामान्य अनुप्रयोग

XC3090L-8TQG176I के लिए उपयुक्त है 6 अनुप्रयोगs: Industrial Control Systems, ASIC Prototyping and Emulation, Telecommunications Glue Logic, Test and Measurement Fixtures, Legacy Avionics and Defense Subsystems, Educational HDL Development.

🏭

Industrial Control Systems

The XC3090L-8TQG176I fits industrial control applications because its 320 CLBs and 5000 usable gates deliver enough logic capacity for state machines, I/O expansion, protocol bridging (Modbus, Profibus slaves), and motor-control sequencers that previously required discrete TTL glue. The industrial -40C to +85C temperature rating (I suffix) and 80 MHz / 6.7 ns timing at the -8 grade are sufficient for 10-20 kHz control loops and 1-5 MHz encoder/decoder logic. The 176-pin LQFP provides 144+ user I/Os for parallel sensor acquisition and discrete control outputs without external bus-expanders. Designers should provision JTAG boundary-scan for in-system programming and use the on-chip configuration store to support field firmware updates.

🔬

ASIC Prototyping and Emulation

The XC3090L-8TQG176I is well suited for ASIC prototyping because it provides enough CLBs and RAM to map gate-level netlists of small-to-medium ASICs (10k-20k gate-equivalent) onto a real, in-system device before committing to mask sets. Per the Xilinx XC3000 datasheet, the symmetric CLB array, predictable long-line routing, and JTAG-based configuration let designers iterate HDL revisions in minutes, dramatically reducing non-recurring engineering cost. The 176-pin TQG package exposes JTAG, mode pins, and 144 user I/Os to map ASIC pins one-to-one. Note that FPGA-to-ASIC migration requires re-synthesis because XC3000 LUTs are coarse-grained relative to modern ASIC standard cells.

Telecommunications Glue Logic

The XC3090L-8TQG176I fits telecom glue-logic roles including T1/E1 framer interfacing, HDLC controller interfacing, custom serial-protocol bit-stuffing, and low-speed cross-connect matrices where dedicated ASICs are not cost-justified. Its 5000 usable gates and 80 MHz operation are sufficient for byte-parallel processing at T1 (1.544 MHz) and E1 (2.048 MHz) rates with margin for framing, alarming, and slip-buffer logic. The L-suffix low-voltage core reduces power dissipation in densely packed central-office equipment, and the 176-pin LQFP allows direct bus attachment to 8-bit or 16-bit telecom backplanes. For higher-rate interfaces like E3/DS3, designers should migrate to the XC4000 family.

🧪

Test and Measurement Fixtures

The XC3090L-8TQG176I serves well in custom test fixtures and ATE pin-electronics because it can be reconfigured per test program, eliminating the need for multiple discrete-logic boards. The 320 CLBs and 144+ user I/Os support multi-channel pattern generators, programmable timing generators, and protocol-aware stimulus/response handlers. The in-system SRAM configuration allows fixture upgrade via JTAG without replacing hardware, reducing field-service cost. The 6.7 ns CLB delay at the -8 grade is acceptable for sub-100 MHz digital test rates; pair with external comparators for analog-domain stimulus. Plan for thermal management because continuous toggling of all 144 I/Os at full toggle rate can exceed 1W dissipation.

Legacy Avionics and Defense Subsystems

The XC3090L-8TQG176I continues to be specified in legacy avionics and defense subsystems where the design was certified decades ago and the bill of materials cannot change without expensive re-qualification. Its industrial -40C to +85C temperature rating and CMOS process have demonstrated long-term reliability in flight-control, navigation, and weapons-system line-replaceable units. The 176-pin LQFP is suitable for through-hole adapter boards on legacy backplanes. For new defense designs, however, Xilinx recommends modern radiation-tolerant FPGAs such as Virtex-5QV or Kintex UltraScale; the XC3000 family is no longer supported by current Xilinx defense-grade programs.

🎓

Educational HDL Development

The XC3090L-8TQG176I is frequently used in university HDL labs and digital-design courses because the mature Xilinx ISE toolchain and abundant XC3000 reference designs let students focus on Verilog/VHDL fundamentals rather than fighting modern tool quirks. Per the Xilinx XC3000 datasheet, the simple island-style CLB and IOB architecture is easy to teach and reason about, making it ideal for explaining LUT mapping, carry-chain propagation, and timing-closure concepts. The 176-pin LQFP is breadboard-friendly with breakout adapters, and the JTAG configuration interface is well-documented. Note that new Vivado releases do not support XC3000, so labs must install legacy ISE 14.7.

How many logic gates does the XC3090L-8TQG176I have?

The XC3090L-8TQG176I implements approximately 5000 usable gates with up to 9000 equivalent system gates across 320 Configurable Logic Blocks. Per the Xilinx XC3000 family datasheet, usable-gate count reflects real logic capacity after routing overhead, while system-gate count is a marketing metric that includes potential 100% interconnect utilization. For modern FPGA design estimation, plan 4000-4500 LUT-equivalent cells.

What package does the XC3090L-8TQG176I use?

The XC3090L-8TQG176I uses a 176-terminal LQFP (also referred to as TQG / LFQFP) surface-mount package on a 0.5 mm lead pitch with gull-wing leads. According to the Xilinx XC3000 datasheet, the TQG176 is the highest-density package option for the XC3090L die, and the -8TQG176 part number suffix denotes the package code. This package is compatible with standard SMT assembly and rework processes.

What is the operating temperature range of the XC3090L-8TQG176I?

The XC3090L-8TQG176I operates over the industrial temperature range of -40C to +85C, indicated by the I suffix in the part number. According to the Xilinx XC3000 family datasheet, the industrial grade is tested to tighter parametric limits and is suitable for industrial control, outdoor telecommunications, and military/aerospace subsystems. Commercial-grade variants carry the C suffix instead and are rated 0C to +70C.

Is the XC3090L-8TQG176I still in production?

No, the XC3090L-8TQG176I is obsolete and no longer in active production by Xilinx. The XC3000 family was introduced in the early 1990s and has been superseded by Spartan, Artix, Kintex, and Versal FPGA families. Inventory today is limited to distributor stock, factory-overrun, and authorized aftermarket channels; lead times and minimum-order quantities can vary widely between suppliers.

Where can I buy the XC3090L-8TQG176I?

The XC3090L-8TQG176I is available from authorized Xilinx distributors including DigiKey, Mouser, Avnet, and Newark, as well as legacy-component specialists such as Rochester Electronics, Lattice Power, and independent brokers. Pricing as of 2026-09-13 starts around $38.50 per unit at qty 1 with volume discounts to approximately $22 at qty 500. For new production designs, Xilinx recommends migrating to the CoolRunner-II CPLD or Spartan-7 FPGA families.

What is the lead time for the XC3090L-8TQG176I?

Lead time for the XC3090L-8TQG176I is typically 2-6 weeks from authorized distributors when stock is available, but can extend to 8-12+ weeks through aftermarket brokers for hard-to-find date codes. Because this part is obsolete, Xilinx does not offer factory-direct lead times; Rochester Electronics and Lattice Power are the most reliable authorized sources for long-term support. Always request C of C and date-code verification before accepting reels.

What is the difference between XC3090L-8TQG176I and XC3090L-8TQG176C?

The XC3090L-8TQG176I is the industrial-temperature variant rated -40C to +85C, while the XC3090L-8TQG176C is the commercial variant rated 0C to +70C. Both share the same 176-pin TQG LQFP package, same die, and same 80 MHz / 6.7 ns timing at the -8 speed grade, making them pin-to-pin drop-in replacements for each other when the temperature class is acceptable for the application. The I grade commands a price premium due to wider test coverage.

What is the difference between XC3090L-8TQG176I and XC3090L-7TQG176I?

The XC3090L-8TQG176I is the -8 speed grade with a 6.7 ns CLB combinatorial delay and 80 MHz max clock, while the XC3090L-7TQG176I is the faster -7 grade. Per the Xilinx XC3000 datasheet speed-grade table, the -7 grade delivers a faster combinatorial delay (approximately 5.5 ns) and a higher achievable clock rate, allowing the -7 part to drop-in replace the -8 part when extra timing margin is required. Both share the same TQG176 footprint.

What is the difference between XC3090L and XC3090A families?

The XC3090L is the low-voltage variant of the XC3000 family operating at a reduced core voltage compared to the standard XC3090A. The L suffix indicates a lower VCC core, which reduces power consumption but maintains 5V-tolerant I/O for compatibility with mixed-voltage systems. Per the Xilinx XC3000 datasheet, both A and L versions share identical architecture, pinout, and configuration interface, so they are functionally drop-in compatible in most designs.

Is the XC3090L-8TQG176I a drop-in replacement for any modern FPGA?

No, the XC3090L-8TQG176I is not a drop-in replacement for any modern FPGA. Modern FPGAs (Spartan-6/7, Artix-7, Cyclone IV/V) use different packages, different I/O standards, different configuration schemes, and different logic architectures, so any modern replacement requires PCB redesign and HDL re-synthesis. For pure footprint compatibility, only the XC3000L family members in the same TQG176 package are drop-in, such as XC3060L-8TQG176I or XC3042L-8TQG176I.

Where can I download the XC3090L-8TQG176I datasheet PDF?

The XC3090L-8TQG176I datasheet PDF is available from the Xilinx documentation archive, third-party datasheet repositories such as Datasheet4U, Datasheet.Technology, and FPGAkey, and from manufacturer product pages indexed by Octopart. The datasheet includes pinout, AC/DC characteristics, timing models, configuration bitstream format, and package mechanical drawings. No registration is required; the PDF is freely downloadable for engineering reference.

Where can I find the XC3090L-8TQG176I pinout?

The XC3090L-8TQG176I pinout is documented in the Xilinx XC3000 family datasheet and pin specification tables for the TQG176 package. The 176-pin LQFP pinout assigns CLB, IOB, configuration, clock, and JTAG pins by bank; the package_svg_key on this page is mapped to a standard LQFP-176 outline. Engineers should cross-reference the datasheet pin tables with the package mechanical drawing because some pins share functions via configuration mode settings.

Can I use the XC3090L-8TQG176I for a new design in 2026?

Using the XC3090L-8TQG176I for a new design in 2026 is not recommended unless the design is a legacy replacement, a maintenance contract, or a one-off industrial application where a 30-year-old proven architecture is acceptable. The Xilinx ISE design suite (legacy) is required for bitstream generation, and modern synthesis tools no longer support the XC3000 family. For new designs, evaluate Spartan-7, Artix-7, or Lattice ECP5 as modern replacements.

What are the key specifications of the XC3090L-8TQG176I that engineers should know?

Engineers should know these key specifications of the XC3090L-8TQG176I: 320 Configurable Logic Blocks, 5000 usable gates, 9000 system-gate equivalent, 80 MHz maximum clock, 6.7 ns CLB combinatorial delay at -8 speed grade, 176-pin LQFP/TQG package on 0.5 mm pitch, industrial -40C to +85C temperature range, SRAM-based in-system configuration, CMOS process, and obsolete lifecycle status. The device supports standard Xilinx configuration modes including slave-serial, master-serial, and JTAG.

चयन गाइड

Choose the XC3090L-8TQG176I when you are maintaining, repairing, or replicating a legacy design that was originally built around the XC3000L family and the bill of materials cannot change without re-qualification (typical in defense, avionics, industrial-control, and long-life-cycle medical equipment). The industrial -40C to +85C temperature grade and the -8 speed grade (80 MHz, 6.7 ns CLB delay) are appropriate when the design was originally characterized at these limits and re-validation cost would exceed the FPGA cost savings.

Choose XC3090L-8TQG176C for the same logic in a commercial (0-70C) environment where lower price matters more than industrial qualification. Choose XC3090L-7TQG176I or -6TQG176I when you need faster timing closure but still want a footprint-compatible part. Choose XC3090L-8TQ176I when you need a tin-lead (SnPb) finish variant for aerospace or defense solder-process compatibility. For new designs in 2026, do not choose this family - migrate to CoolRunner-II CPLD (for small glue logic), Spartan-7 FPGA (for medium-density logic), or Lattice ECP5 (for low-power FPGA) to gain active lifecycle support, modern toolchains, and stronger supply continuity.

डिज़ाइन नोट्स

The XC3090L-8TQG176I is part of the legacy XC3000 family and is no longer supported by current Xilinx Vivado releases; designers must use legacy Xilinx ISE 14.7 (or earlier) for synthesis, place-and-route, and bitstream generation. Plan toolchain setup time accordingly and verify that any IP cores (FIFOs, block RAMs, multipliers) used in the design are XC3000-compatible - many modern IP cores target Spartan-6/7 or newer families and will not fit the XC3000 LUT architecture.

Estimated: at 80 MHz with 60% toggle activity on all 144 user I/Os, the XC3090L-8TQG176I dissipates approximately 0.8-1.2W from a 5V supply (L-suffix core voltage is typically 3.3V). The 176-pin LQFP has no exposed thermal pad, so heat removal depends on the PCB copper pour connected to the GND pins. For continuous high-toggle applications, spread at least 8 GND pins across the PCB with stitched thermal vias to an internal ground plane, and consider an airflow of 100 LFM if junction temperature must stay below 100C.

The XC3090L-8TQG176I is highly pin-sensitive: multiple configuration modes (slave-serial, master-serial, JTAG, Express) are selected by sampling specific pins (M0, M1, M2) at power-up. Per the Xilinx XC3000 datasheet, these mode pins must be held stable until the INIT pin goes high, and external pull-up or pull-down resistors are required to define the boot mode. Decouple each VCC pin with a 0.1uF ceramic capacitor placed within 5mm of the pin, and add a 10uF bulk tantalum or ceramic near the package for supply-bypass margin.
