XC3090L-8TQ176I 概覽
The Xilinx XC3090L-8TQ176I is a CMOS Field-Programmable Gate Array from the legacy XC3000 series offering 320 Configurable Logic Blocks (CLBs), a maximum of 5000 equivalent gates, and up to 6000 usable gates, housed in a 176-pin TQFP (TQ176) surface-mount package with industrial temperature grading. The device is built on a 0.6 um CMOS process and operates from a single 5V supply with a maximum clock frequency of 80 MHz and a combinatorial CLB delay of 6.7 ns at the -8 speed grade.
A Field-Programmable Gate Array (FPGA) is a type of programmable logic device (PLD) that combines a perimeter of user-configurable I/O Blocks (IOBs) with a core array of Configurable Logic Blocks (CLBs) and programmable interconnect, all controlled by an SRAM-based configuration program store. FPGAs sit hierarchically under programmable logic, then digital integrated circuits, and ultimately the broader semiconductor taxonomy; the XC3000 family occupies the early-generation, 5V legacy tier that preceded modern low-power Virtex and Kintex families.
Key features include 144 user I/Os in the TQ176 footprint, distributed on-chip RAM, JTAG boundary-scan support, and tri-state buffers per IOB. The architecture supports asynchronous and synchronous design entry through Xilinx's XACT development system, including schematic capture, automatic place-and-route, logic and timing simulation, and interactive design optimization. The -8 speed grade denotes the mid-tier performance bin of the XC3090L family, with faster -9/-10 grades unavailable in this part number and slower -6/-7 grades reserved for cost-sensitive designs.
Typical applications include industrial control glue logic, legacy telecom backplane interfaces, military and aerospace retrofit boards, and educational laboratory trainers where designers migrate proven XC3000 designs forward without re-validating timing closure. The wide 5V tolerance and TTL-compatible I/Os also make it suitable for bridging older ASICs to newer microprocessors.
When designing with this part, treat the 6.7 ns CLB delay as the budget floor for the slowest logic path: multiply by the number of cascaded CLBs and add interconnect delay to estimate the system clock. Configuration storage is volatile, so external PROMs (XC17xx) are required for standalone boot.
This page synthesizes distributor stock, lifecycle status, same-package alternatives, and practical design notes not found in the standalone XC3090L datasheet, designed to assist sourcing engineers working on legacy Xilinx FPGA maintenance and obsolescence mitigation.

典型應用
XC3090L-8TQ176I 適用於 6 應用s: Industrial Control Glue Logic, Legacy Telecom Backplane Interface, Military and Aerospace Retrofit Boards, Educational Laboratory Trainers, ASIC Prototype Bridge Logic, Test and Measurement Front Ends.
Industrial Control Glue Logic
The XC3090L-8TQ176I's 320 CLBs and 144 user I/Os make it well suited for industrial control glue logic where 5V TTL-compatible signalling must interface with legacy microcontrollers, opto-isolated inputs, and 24V relay drivers. Its 80 MHz maximum clock and 6.7 ns CLB delay comfortably meet typical PLC scan-cycle budgets of 1-10 MHz. The industrial temperature grade (-40C to +85C) ensures operation on factory floors, while the volatile SRAM configuration allows last-minute firmware updates over JTAG during commissioning.
推薦
Legacy Telecom Backplane Interface
Telecom backplanes built in the mid-1990s often route 5V TTL signalling between line cards, and the XC3090L-8TQ176I was a popular glue-logic choice for protocol bridging, clock distribution, and alarm aggregation. Its 144 I/Os in the TQ176 footprint are sufficient for 8-bit-wide parallel buses plus chip selects and interrupt lines, while the 80 MHz clock supports E1/T1 framing at 2.048 MHz. Telecom maintenance programs now use this part to extend the service life of installed equipment rather than redesigning entire shelves.
推薦
Military and Aerospace Retrofit Boards
Defense and aerospace platforms with multi-decade service lives frequently retrofit avionics, radar signal conditioning, and secure-communication subsystems using legacy Xilinx XC3000 parts. The XC3090L-8TQ176I's industrial temperature grade, ceramic-friendly TQFP footprint, and documented timing closure behaviour (6.7 ns CLB delay) make it a low-risk replacement when a board fails and the original BOM must be honoured. Engineers maintain bitstream libraries so the new device uses identical place-and-route databases as the fielded hardware.
推薦
Educational Laboratory Trainers
University digital-logic and computer-architecture laboratories continue to use the XC3090L-8TQ176I on FPGA trainer boards because the XACT development system runs on legacy Windows and DOS environments that students learn without licensing fees. The 5000-gate capacity accommodates 8-bit CPUs, simple VGA controllers, and UART peripherals - all within reach of a single semester project. Its 5V I/O tolerance also lets students interface directly with classic 74-series TTL without level shifters.
推薦
ASIC Prototype Bridge Logic
Before committing to a gate-array ASIC, design teams frequently use the XC3090L-8TQ176I as a prototype vehicle for glue logic that will eventually move into the ASIC's standard-cell library. The 320 CLBs and 80 MHz clock provide a realistic timing baseline, and the JTAG port allows in-system reconfiguration as the design iterates. This pre-silicon prototyping stage reduces risk by validating pin-out and timing assumptions months before mask release.
推薦
Test and Measurement Front Ends
Bench-top instruments such as logic analyzers, protocol exercisers, and pattern generators use the XC3090L-8TQ176I for pattern sequencing, trigger logic, and front-end capture. Its 144 user I/Os accommodate up to 18 channels of 8-bit capture, while the 80 MHz clock supports 100 Mbps pattern generation when combined with an external serializer. The 5V TTL I/Os interface directly with legacy parallel-probe pods and front-panel connectors.

What type of device is the Xilinx XC3090L-8TQ176I?
The XC3090L-8TQ176I is a CMOS Field-Programmable Gate Array from the Xilinx XC3000 series. According to the Xilinx XC3000 datasheet, it integrates 320 Configurable Logic Blocks (CLBs), delivers up to 5000 equivalent gates and 6000 usable gates, and runs from a 5V supply. It is housed in a 176-pin TQFP package with industrial temperature grading.
What is the maximum clock frequency of the XC3090L-8TQ176I?
The XC3090L-8TQ176I operates at a maximum clock frequency of 80 MHz at the -8 speed grade, with a combinatorial CLB delay of 6.7 ns. This makes it suitable for legacy 5V logic replacement, industrial control glue logic, and telecom backplane designs where modern sub-nanosecond FPGAs are unnecessary and over-spec.
How many user I/O pins does the XC3090L-8TQ176I expose?
The XC3090L-8TQ176I exposes 144 user I/O pins within its 176-pin TQFP package. The remaining 32 pins are dedicated to power, ground, configuration mode, JTAG, and the dedicated DONE/INIT/CCLK configuration chain, matching the standard XC3000 TQ176 pinout documented in the Xilinx family datasheet.
Where can I buy the XC3090L-8TQ176I and what is the price?
As of 2026-09-13, the XC3090L-8TQ176I is listed on Octopart, Partstack, Jotrin Electronics, Vyrian, Microchip USA, and BesenChips. The component is obsolete at Xilinx but remains in limited distributor stock. Pricing is approximately $145 in single-piece quantity and drops to roughly $85 at 1000-piece volumes; call for a current quote because inventory fluctuates weekly.
What is the lead time and stock status of the XC3090L-8TQ176I?
As of 2026-09-13, lead time for the XC3090L-8TQ176I ranges from immediate (in-stock at specialist distributors such as BesenChips and Jotrin) to 8-12 weeks when ordered through franchised channels. Because the part is marked obsolete by Xilinx, large orders should be confirmed in writing before issuing a purchase order.
Is the XC3090L-8TQ176I still in production by Xilinx?
No. The XC3090L-8TQ176I is classified as obsolete by Xilinx. The XC3000 family was discontinued in the late 1990s. Today the part is only available through aftermarket distributors, with pricing reflecting inventory scarcity rather than manufacturing cost.
What is the difference between XC3090L-8TQ176I and XC3090L-8TQ176C?
The XC3090L-8TQ176I is specified for the industrial temperature range (-40C to +85C), while the XC3090L-8TQ176C is specified for the commercial range (0C to +70C). Both share the same TQFP-176 package and pinout and are drop-in compatible for designs whose operating environment falls within the commercial window.
XC3090L-8TQ176I vs XC3090L-7TQ176I - which is faster?
The XC3090L-8TQ176I is the -8 speed grade with a 6.7 ns CLB delay and 80 MHz maximum clock, while the XC3090L-7TQ176I is the slower -7 grade. For designs that meet timing at the -7 grade, the -8 part offers roughly 10-15% timing margin; choose the -7 only when cost, not performance, drives the decision.
What is the best drop-in replacement for the XC3090L-8TQ176I?
The best drop-in replacement for the XC3090L-8TQ176I is the XC3090L-8TQG176I - same die, same TQ176 footprint, pin-to-pin compatible - or the commercial-temperature XC3090L-8TQ176C if your design only operates between 0C and 70C. Both retain identical timing and feature sets, differing only in temperature grade or lead finish.
What is the difference between XC3090L-8TQ176I and XC3090L-8PC84I?
The XC3090L-8TQ176I ships in a 176-pin TQFP with 144 user I/Os, while the XC3090L-8PC84I ships in an 84-pin PLCC with a much smaller I/O count. Both are -8 speed grade and industrial temperature, but the packages are not interchangeable - any migration requires PCB redesign, so they are not drop-in equivalents.
Where can I download the XC3090L-8TQ176I datasheet PDF?
The XC3090L-8TQ176I datasheet PDF is available at pdf.datasheet.technology under the Xilinx XC3090L family documentation. The original Xilinx datasheet has also been archived on Digchip and Datasheet4u. Expect to download the family datasheet rather than a per-MPN document because the XC3000 series is documented as a family.
Where can I find the XC3090L-8TQ176I pinout?
The TQ176 pinout is documented in the Xilinx XC3000 family datasheet, available via pdf.datasheet.technology and Digchip. Pin 1 is at the top-left of the TQFP package with the dot marker; the 144 user I/Os are organized as 8 banks of 18, with shared VCCO/GND pairs every 12 pins.
Is the XC3090L-8TQ176I suitable for new designs in 2026?
The XC3090L-8TQ176I is not recommended for new designs in 2026. The XC3000 series is obsolete, the 5V supply is incompatible with modern low-voltage logic, and the 80 MHz / 6.7 ns performance is far below current 7-series or Versal FPGAs. It is appropriate only for legacy board repair and obsolescence mitigation.
How does the XC3090L-8TQ176I compare to a modern Xilinx 7-series FPGA?
The XC3090L-8TQ176I delivers 5000 equivalent gates at 80 MHz on a 0.6 um 5V CMOS process, while a modern Xilinx 7-series device such as the XC7A35T delivers 33,280 logic cells at 450+ MHz on 28 nm. The 7-series offers roughly 6-7x the logic density and 5-6x the clock rate at one-tenth the core voltage.
Does the XC3090L-8TQ176I need an external configuration PROM?
Yes. The XC3090L-8TQ176I uses volatile SRAM-based configuration, so it loses its bitstream on power-down. For standalone boot, pair it with a Xilinx XC17xx-series one-time-programmable configuration PROM on the standard serial-mode (CCLK/DONE/INIT) interface, or use a microcontroller to load the bitstream at reset.

選型指南
Choose the XC3090L-8TQ176I when you need a drop-in, industrial-temperature, mid-speed XC3090L variant for an existing TQ176-PCB design that operates between -40C and +85C and requires 80 MHz timing closure. For commercial-temperature indoor designs, the XC3090L-8TQ176C is functionally identical and typically cheaper. For Pb-free assembly requirements, choose the XC3090L-8TQG176I (industrial) or XC3090L-7TQG176I (industrial, slower). For cost-sensitive designs that can tolerate a 10-15% timing penalty, the -7 grades are recommended. Avoid the -6 grades unless timing closure is trivial. All six MPNs in the alternatives list share the same TQFP-176 footprint and pinout, enabling PCB reuse across commercial/industrial, Pb/Pb-free, and -6/-7/-8 speed combinations.

主要差異化特點
- Industrial temperature grade (-40C to +85C) (對比XC3090L-8TQ176C)
- Mid-tier -8 speed grade (對比XC3090L-7TQG176I)
- Highest speed within the XC3090L TQ176 industrial family (對比XC3090L-6TQG176I)
設計說明
The XC3090L-8TQ176I uses volatile SRAM configuration, so the bitstream is lost at every power-down. A Xilinx XC17Vxx-series configuration PROM (or microcontroller bitstream loader) is mandatory for standalone boot. Estimate: assume ~250 ms configuration time from a 1 Mbit serial PROM at the default CCLK rate; design reset circuits to hold downstream logic in reset until DONE asserts.
The TQFP-176 package has gull-wing leads on a 0.5 mm pitch with a 24x24 mm body. Provide at least four vias under the exposed center pad (if present on the -L variant) or under the device body to dissipate heat and reduce ground bounce. Place 0.1 uF decoupling capacitors within 5 mm of every VCC/VCCO pin, plus a 10 uF bulk tantalum on each supply rail.
Estimated: at maximum toggle activity (~80 MHz internal logic toggling ~50% of 320 CLBs at 5V VCC), power dissipation is approximately 0.5-1 W. The TQFP-176 with theta_JA around 35 C/W (no airflow, no heat spreader) yields a 25-35 C junction rise, well within the industrial 85 C limit. For sealed enclosures, derate by 30% and verify with a thermocouple.
