Typical Applications

XC3090L-6TQ176C is suitable for 6 applications: Legacy 3.3V Glue-Logic Replacement, Retrocomputing Custom Peripheral Controller, Industrial Parallel-to-Serial Converter, Educational FPGA Training Platform, 3.3V / 5V Mixed Logic Level Bridge, Legacy Board Repair / Production Continuation.

🔧

Legacy 3.3V Glue-Logic Replacement

The XC3090L-6TQ176C fits legacy 3.3 V glue-logic replacement because its 320 CLBs and ~9,000 gates provide enough capacity to absorb multiple discrete 74HC/74LVC logic chips into a single programmable device, while its 144 user I/O pins cover standard 16-/32-bit bus glueing tasks. Placed on a 3.3 V rail with 0.1 uF + 10 uF decoupling per VCC cluster per the datasheet, the device consolidates address decoding, bus arbitration, and timing logic on a single 176-pin TQFP footprint. Compared with discrete SSI/MSI logic, this delivers PCB area savings and BOM simplification at the cost of a mandatory XC17xx boot PROM.

🖥️

Retrocomputing Custom Peripheral Controller

The XC3090L-6TQ176C suits retrocomputing peripheral controllers because its 5 ns combinatorial delay and 220 MHz toggle rate are well matched to 8-bit and 16-bit ISA bus cycles, and its 3.3 V I/O is compatible with vintage TTL bus pull-up designs. With 144 user I/O it can implement a full custom ISA card including bus interface, DMA, and interrupt logic on a single device. The TQFP-176 package is straightforward to wire into retro backplanes using a TQFP-to-DIP adapter PCB, making it popular for hobbyist retrocomputing projects as of 2026-09-13.

🏭

Industrial Parallel-to-Serial Converter

The XC3090L-6TQ176C works well in industrial parallel-to-serial converter applications because its 144 user I/O easily handles 32-bit parallel input ports, while the 3.3 V VCCINT supports low-power industrial operation with 5 V tolerant inputs. Typical designs use the CLBs as parallel register banks feeding high-speed serial state machines that bit-bang UART, SPI, or LVDS-like streams. Operating temperature of -40 C to +85 C and TQFP-176 industrial-grade packaging make it suitable for factory-floor equipment where commercial-grade parts are sufficient.

🎓

Educational FPGA Training Platform

The XC3090L-6TQ176C is widely used in educational FPGA training platforms because the XC3000 toolchain (XACTstep, then later ISE WebPACK) has been frozen at stable, well-documented versions that students can install without licensing friction. With ~9,000 gates and 144 user I/O the device provides enough headroom for typical coursework (state machines, FSMs, UART controllers, simple CPUs), while the TQFP-176 package is breadboard-friendly via adapter boards. The obsolete lifecycle status makes it cheap on broker markets as of 2026-09-13, reducing the per-student cost for university labs.

🌐

3.3V / 5V Mixed Logic Level Bridge

The XC3090L-6TQ176C serves as a robust mixed-logic-level bridge because its inputs are 5 V tolerant on the standard XC3000L pad design and its outputs swing to 3.3 V CMOS levels, allowing it to sit transparently between a 5 V microcontroller bus and a 3.3 V peripheral block. With 144 user I/O, multiple independent bridges (e.g., data bus + address bus + control signals) can share one device, eliminating point-to-point level shifter ICs. The 3.3 V VCCINT and per-pin bus-hold circuits provide predictable behavior across mixed-voltage power-up sequences.

Legacy Board Repair / Production Continuation

The XC3090L-6TQ176C is primarily sourced today for legacy board repair and production continuation where the original 1990s/2000s design must continue to be manufactured in small volumes. Independent brokers and reclamation distributors (Jotrin, Kynix, FPGAkey, VEKEMO) stock tested or pulled units specifically for this purpose. Engineers typically order with extended incoming inspection and use a programmed-and-tested sourcing contract; counterfeit risk for this part is elevated as of 2026-09-13, so sourcing traceable units with Xilinx date codes is critical.

What is the XC3090L-6TQ176C?

The XC3090L-6TQ176C is a Xilinx XC3000L low-voltage (3.3 V) FPGA in a 176-pin TQFP (TQ) package, offering approximately 9,000 usable gates and 320 configurable logic blocks arranged in a 16 x 16 array. It is the -6 speed grade and is built on 0.8 micron CMOS SRAM technology, so the bitstream must be reloaded from a configuration PROM at every power-up. As of 2026-09-13 this part is listed as obsolete by major franchised distributors.

Where can I buy the XC3090L-6TQ176C?

As of 2026-09-13 the XC3090L-6TQ176C is available only through independent distributors (Jotrin, Kynix, DigiPart, FPGAkey) and broker stock such as VEKEMO. Major franchised distributors like DigiKey and Mouser no longer carry the part as active stock. Pricing varies widely by test/condition; expect roughly $9.95 - $18.50 per unit depending on quantity break, with higher prices for known-good programmed units.

What is the price of the XC3090L-6TQ176C?

Obsolete Xilinx XC3000L parts typically price between $9.95 and $18.50 per unit on the open market as of 2026-09-13, depending on the quantity break (1, 10, 100, 500, 1000) and whether the units are tested, programmed, or pulled from old inventory. New-old-stock from independent brokers commands a premium; counterfeits are a known risk for this part, so source only from brokers that provide traceability documentation.

What is the lead time for the XC3090L-6TQ176C?

The lead time for XC3090L-6TQ176C is typically 4-8 weeks when ordered through independent distributors and broker stock as of 2026-09-13, since the part is no longer in production. Some independent distributors ship from in-stock inventory within 1-2 business days; others wait for the manufacturer-traceable stock to arrive from their channel. Plan ahead - do not assume same-day availability.

Is the XC3090L-6TQ176C in stock?

Yes, the XC3090L-6TQ176C is in stock at several independent distributors as of 2026-09-13, including Jotrin, Kynix, DigiPart, and FPGAkey. However, this is broker/OEM stock, not new production - major franchised distributors do not have active stock and the part is marked obsolete in the Xilinx product family. Quantities at each distributor are limited and may change daily.

What is the difference between the XC3090L and the XC3090?

The XC3090L is the low-voltage (3.3 V) variant of the XC3090 FPGA; the original XC3090 operates from 5 V. According to the Xilinx XC3000L datasheet, the XC3090L has the same logic capacity (320 CLBs, ~9,000 gates), the same pinout in TQ176, but lower power consumption and a different VCCINT rating (3.3 V vs 5 V). For most designs the two are pin-compatible in TQ176 package, but the supply voltage and I/O bank drive characteristics differ.

What is the difference between the XC3090L-6TQ176C and the XC3090L-7TQ176C?

The XC3090L-6TQ176C is speed grade -6 (approximately 5 ns combinatorial delay), while the XC3090L-7TQ176C is speed grade -7 (slower, typically 7-7.5 ns). Both share the same TQFP-176 (TQ) footprint and pinout, so they are drop-in replaceable on existing PCBs when timing margins permit. The -7 variant is generally cheaper on the broker market as of 2026-09-13.

When should I choose the XC3090L-6TQ176C over a modern FPGA?

Choose the XC3090L-6TQ176C only when (a) you must repair a legacy board that already has this part on it, (b) you need a 3.3 V low-cost glue-logic device for a retrocomputing project, or (c) you are designing an educational FPGA training platform that uses the classic Xilinx XC3000 toolchain. For new designs, modern Xilinx 7-series (Spartan-7, Artix-7), Lattice iCE40, or Gowin GW1N parts offer vastly more logic, lower power, and better tool support at lower cost.

Is the XC3090L-6TQ176C pin-compatible with the XC3190A or XC4000 series?

No, the XC3090L-6TQ176C is NOT pin-compatible with the XC3190A or the XC4000 family even in the same TQ176 package. The XC3090L has 144 user I/O with a specific pinout, while XC3190A and XC4000 devices use different I/O and pin assignments in the same TQ176 footprint. Cross-family pin compatibility only exists within the XC3000/XC3000A family itself; XC3100A adds IOB features but is pin-compatible with XC3000 in TQ176.

What is the best drop-in replacement for the XC3090L-6TQ176C?

The best drop-in replacement for the XC3090L-6TQ176C is the XC3090L-7TQ176C (same package, same logic, slower speed grade - pin-for-pin compatible). Another valid drop-in alternative is the XC3190A-6TQ176C for designs that need more logic, since the XC3190A is pin-compatible with the XC3090L in TQ176 (the XC3100A family extended pinout within the same footprint). Both come from the same Xilinx XC3000 toolchain and use the same bitstream format.

Where can I download the XC3090L datasheet PDF?

The Xilinx XC3090L datasheet PDF is available from the Xilinx legacy product archive and from third-party datasheet aggregators such as datasheet4u.com and digchip.com. According to the XC3090L datasheet index page at datasheet4u.com, the document covers functional description, pinout, configuration modes, timing, and DC/AC characteristics for the entire XC3090L family including the -6 speed grade TQ176 package. The official Xilinx archive PDF is the canonical source.

Where can I find the XC3090L-6TQ176C pinout?

The XC3090L-6TQ176C pinout is provided in the XC3090L family datasheet (TQ176 chapter), showing 144 user I/O pins plus dedicated configuration (M0/M1/M2), clock (CCLK), data (DIN/DOUT), and power/ground pins arranged in a TQFP-176 1.0 mm pitch package. Pin 1 is at the top-left corner with the standard TQFP dot marker, and pins are numbered counter-clockwise around the package perimeter.

What configuration memory does the XC3090L-6TQ176C need?

The XC3090L-6TQ176C uses SRAM-based configuration cells that are volatile, so a boot PROM is mandatory at every power-up. According to the Xilinx XC3000 family reference, a standard XC17xx series serial configuration PROM (e.g., XC1736A, XC1765) provides a one-time-programmed bitstream source, while a microcontroller can drive the serial DIN/CCLK pins directly for in-system reconfiguration. Plan for the boot PROM footprint when designing new PCB layouts.

Is the XC3090L-6TQ176C RoHS compliant?

The XC3090L-6TQ176C is a legacy 0.8 micron CMOS part from the 1990s and was originally released before RoHS took effect, so most XC3090L stock in circulation as of 2026-09-13 is NOT RoHS-certified. Some distributors advertise RoHS-compliant variants, but these are usually third-party re-tested units and not Xilinx-certified. For new RoHS-required designs, choose a modern FPGA family instead.

What are the key specifications engineers should know about the XC3090L-6TQ176C?

Engineers evaluating the XC3090L-6TQ176C should know six core facts: (1) 320 CLBs / ~9,000 usable gates; (2) 144 user I/O in TQ176 package; (3) 3.3 V VCCINT supply; (4) -6 speed grade with ~5 ns combinatorial delay; (5) SRAM-based volatile configuration that requires an XC17xx boot PROM; (6) obsolete lifecycle status with no RoHS certification. Source via trusted brokers only - counterfeits of this part are common.

Is there a Lattice or Altera equivalent for the XC3090L-6TQ176C?

No, there is no direct cross-brand drop-in replacement for the XC3090L-6TQ176C in the same TQ176 footprint. The Altera (now Intel) equivalent FPGAs of that era (FLEX 8000, FLEX 10K, MAX 7000) used different package pinouts and different bitstream formats. Cross-brand alternatives must be designed in on a new PCB footprint; only within-family Xilinx parts (XC3090L-7TQ176C, XC3100A, XC3190A in TQ176) are pin-compatible drop-ins.

Choose the XC3090L-6TQ176C when repairing a legacy 3.3 V Xilinx board that originally shipped with this exact part, or when designing a 3.3 V glue-logic replacement where the XC3000 toolchain (XACTstep / ISE WebPACK) is acceptable. Choose the XC3090L-7TQ176C if timing margins permit slower logic (saves broker cost). Choose the XC3190A-6TQ176C if you need more logic capacity and have a 5 V supply available. For new designs, prefer a modern 7-series or iCE40 FPGA unless you are constrained to the XC3000 toolchain.

Key Differentiators

Lowest cost speed-grade drop-in within XC3000L TQ176 (vs XC3090L-7TQ176C)
Stays within the XC3000L low-voltage family (3.3 V VCCINT) (vs XC3190A-6TQ176C)
Highest volume in the XC3090L family, broadest broker availability (vs XC3090L-8TQ176C)

Design Notes

The XC3090L-6TQ176C requires a 3.3 V VCCINT supply that must ramp monotonically from 0 to 3.3 V within the datasheet-specified power-on reset time. According to the Xilinx XC3000L datasheet, each VCC pin (TQs are interspersed around the TQ176 perimeter) needs a 0.1 uF ceramic decoupling capacitor placed as close to the pin as possible, plus a single 10 uF bulk cap per VCC bus. Estimated: a fully utilized XC3090L drawing ~150 mA quiescent plus dynamic current can pull 300-400 mA total; budget the 3.3 V regulator for at least 500 mA headroom.

Do NOT assume the XC3090L-6TQ176C retains its bitstream through power-down. The SRAM configuration cells are volatile, and a missing boot PROM (XC17xx series) means the device will not configure at all. Always place an XC1736A or larger XC1765 on the board, route DIN/CCLK/PROG/DONE per the datasheet reference schematic, and verify the PROM-to-FPGA daisy-chain order on first bring-up. Counterfeit XC3000L parts are common in the broker market as of 2026-09-13 - inspect date codes and Xilinx laser markings before use.

Route all 144 user I/O traces with controlled impedance if any run >50 mm, even though the XC3090L is a slow FPGA. Use a 4-layer PCB with continuous ground plane beneath the TQ176 footprint - the package has no exposed pad, so all thermal dissipation must occur through the perimeter VCC/GND pins. Per the XC3000L datasheet, maintain at least 0.2 mm clearance between adjacent I/O traces to avoid coupling, and group synchronous-bus traces (clock, data strobes) in matched-length groups for reliable timing closure at the -6 speed grade (~5 ns).
