XC3090L-8TQ176I 概述
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.

典型应用
XC3090L-8TQ176I 适用于 6 应用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.
推荐
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.
推荐
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.
推荐
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.
推荐
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.
推荐
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.

关键差异点
- Industrial temperature grade (-40C to +85C) （对比 XC3090L-8TQ176C)
- Mid-tier -8 speed grade （对比 XC3090L-7TQG176I)
- Highest speed within the XC3090L TQ176 industrial family （对比 XC3090L-6TQG176I)
设计说明
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.
合规信息
Standard (non-G) suffix parts use SnPb lead finish. For Pb-free assembly, choose the -G variants (XC3090L-8TQG176I). The XC3000 family predates AEC-Q100, so this part is not qualified for automotive safety applications.
