XC3090L-6TQG176C 概述

The Xilinx XC3090L-6TQG176C is a member of the XC3000L Low-Voltage Logic Cell Array FPGA family, providing 138 user I/O pins in a 176-pin Thin Quad Gull-Wing (TQG) surface-mount package with -6 speed grade and commercial operating temperature. This device is part of the legacy XC3000L series that operates from a 3.3V supply, distinguishing it from the original 5.0V XC3000A family.

A Field Programmable Gate Array (FPGA) is a reconfigurable semiconductor device whose logic function is defined by user-programmed configuration memory rather than fixed mask wiring. In the hierarchy of programmable logic, FPGAs sit above simpler PLDs and below structured ASICs, offering higher logic density, distributed RAM, and dedicated I/O cells. The XC3000L family specifically targets low-voltage (3.3V) designs where battery life or power budget is critical, such as portable telecom, handheld instrumentation, and mobile peripherals.

Key features of the XC3090L-6TQG176C include an array of 138 user I/O, six dedicated clock buffers (two on-chip oscillator inputs and four global clock buffers), a 6ns combinatorial logic delay, configurable logic blocks (CLBs) organized into rows and columns, and a perimeter I/O ring supporting a wide range of I/O standards of its era. The device integrates a complete development tool flow on legacy Xilinx design environments with schematic capture, automatic place-and-route, timing simulation, and an interactive design editor.

The XC3090L-6TQG176C uses a SRAM-based configuration memory, allowing unlimited re-programmability and in-system configuration via the standard Xilinx serial/parallel configuration interface. Its architecture includes symmetrical routing, fast carry logic for arithmetic functions, and dedicated 3-state buffers on each I/O pin for bus-oriented designs. The -6 speed grade delivers 6ns tpd on a typical combinatorial path.

Typical applications include glue logic replacement, custom state machines, peripheral controllers for portable systems, DSP preprocessing in early-stage pipelines, communication protocol bridges (UART, I2C, SPI controllers), and low-volume prototyping that does not justify an ASIC NRE. The 3.3V core operation makes it well suited to battery-powered or low-power industrial systems of the late 1990s.

When designing with this FPGA, be aware of its legacy status. Designers should verify that the 3.3V core voltage is compatible with the rest of the system, plan for a JTAG or Xilinx XChecker-compatible programming cable, and source configuration PROMs or in-system loading through a microcontroller. The TQG176 footprint is shared across the XC3090L family, so layout reuse is possible across -4, -5, and -6 speed grades.

This page synthesizes distributor availability, drop-in alternative cross-references, package diagram, and design notes not bundled in the original manufacturer datasheet, giving procurement and engineering teams a single source for current sourcing decisions.

XC3090L-6TQG176C 适用于 7 应用s: Portable Telecom Interface Bridge, Industrial Control Glue Logic Replacement, Custom DSP Preprocessor, Legacy Network Peripheral Controller, Test & Measurement Instrument Front-End, Aerospace Avionics Databus Bridge (Legacy), Medical Imaging Preprocessor (Legacy).

📱

Portable Telecom Interface Bridge

The XC3090L-6TQG176C's 138 user I/O and 3.3V core supply fit late-1990s portable telecom interfaces that must consolidate multiple slow-speed serial buses (UART, SPI, I2C) without drawing 5V core power. Its 6 ns combinatorial delay supports on-the-fly protocol muxing at modem baud rates up to 115 kbps and basic packet header parsing. Placed between a baseband ASIC and the radio front-end, it acts as a glue-logic protocol translator. The 3.3V rail reduces battery drain by roughly 30% versus a 5.0V XC3090A solution, an important consideration for handheld PDAs and early smartphones.

🏭

Industrial Control Glue Logic Replacement

For factory-floor PLCs and motor controllers, the XC3090L-6TQG176C replaces dozens of 74-series TTL/MSI chips with a single programmable device, simplifying BOM and reducing board area. Its symmetric routing and dedicated 3-state buffers per pin simplify bus-oriented designs common in industrial backplanes. The 6 ns tpd handles encoder pulse counting and quadrature decoding at moderate motor speeds. Designers typically include a Xilinx XC1700-series configuration PROM on board so the design re-boots deterministically after power cycling on the factory floor.

Custom DSP Preprocessor

In early-stage audio or video DSP pipelines, the XC3090L-6TQG176C implements FIR filter pre-processing, sample-rate conversion, and packetization before handing data to a dedicated DSP or host CPU. The 6 ns tpd is sufficient for ~80 MHz pipelined FIR operations on 8-bit data streams, and the 138 I/O support wide parallel data buses plus auxiliary control signals. Its reconfigurable SRAM core allows field firmware updates to refine DSP coefficients without PCB rework, an advantage over a fixed-function ASIC.

Legacy Network Peripheral Controller

Routers, bridges, and access switches from the late 1990s used XC3000L-series FPGAs as peripheral controllers that offloaded MAC/PHY handshaking, LED driving, and watchdog timing from the main CPU. The XC3090L-6TQG176C with 138 user I/O handles Ethernet PHY MDIO buses, status LED matrices, and packet descriptor FIFOs in parallel. Its 3.3V supply integrates cleanly with the surrounding ASICs of the era. Modern replacements should consider Spartan-6 or 7-series for new designs.

Test & Measurement Instrument Front-End

Bench-top logic analyzers, oscilloscope front-ends, and protocol exercisers of the late 1990s used the XC3090L-6TQG176C to implement pattern generation, timing measurement, and trigger logic. Its 6 ns tpd supports sampling clock generation up to ~80 MHz, and the 138 I/O accommodate parallel test vector buses. The commercial temperature grade suits indoor laboratory use. Engineers writing firmware for these instruments often pair the FPGA with a Xilinx XC1700-series configuration PROM for one-time programmable boot behavior.

Aerospace Avionics Databus Bridge (Legacy)

Older avionics databus systems (MIL-STD-1553, ARINC 429) used the XC3090L-6TQG176C as a bridge between redundant bus controllers and downstream LRUs. Its 138 I/O support dual-redundant channel pairs plus discrete avionics discretes. Designers typically pair it with industrial-temperature variants for cockpit thermal cycling. Note that for modern aerospace programs, radiation-hardened FPGAs (Microsemi RTG4, Xilinx XQR) are now mandatory - the XC3090L family is unsuitable for new flight designs.

Medical Imaging Preprocessor (Legacy)

Early ultrasound and patient-monitor front-ends used the XC3090L-6TQG176C to preprocess raw transducer signals - including band-pass filtering, envelope detection, and beamforming control - before passing data to a DSP. The 3.3V core is friendly to battery-powered portable monitors, and the 138 I/O accommodate multi-channel parallel transducer buses. Modern FDA-compliant medical designs should use current-generation FPGAs with documented IEC 62304 lifecycle support; the XC3000L family is obsolete and unsuitable for new medical device approvals.

What are the key specifications of the XC3090L-6TQG176C that engineers should know?
The XC3090L-6TQG176C key specifications for engineers are: 138 user I/O, 176-pin TQG176 surface-mount package, 3.3V core supply, 6 ns combinatorial delay (speed grade -6), commercial 0C to +70C operating range, SRAM-based in-system programmable configuration memory, and Xilinx XC3000L family architecture with symmetric routing and dedicated 3-state buffers on each I/O. Sourced from Xilinx XC3090L family datasheet.

选型指南

Choose the XC3090L-6TQG176C when maintaining a legacy 3.3V system that needs a moderate-density (138 I/O) FPGA with proven XC3000L family tooling, especially where the existing PCB layout and configuration PROM are already designed around the TQG176 footprint. For new designs in 2026, evaluate current-generation replacements first: Spartan-6, Artix-7, or Lattice ECP5 offer higher density at lower power with active lifecycle support and modern toolchains. Among same-family alternatives, the XC3090L-6TQ176C and XC3090L-6TQ176I are pin-compatible drop-ins, with the I-suffix preferred for industrial temperature environments. The XC3090L-100PC84C and XC3090L-125PC84C variants require PCB redesign because they ship in a smaller PLCC-84 package - only consider them when board space is the dominant constraint.

关键差异点

  • Low-voltage 3.3V core reduces power vs 5.0V XC3090A （对比 XC3090A-6TQG176C)
  • Identical TQG176 footprint enables direct PCB swap （对比 XC3090L-6TQ176I)
  • Re-programmable SRAM configuration vs one-time-programmable XC3000A PROMs （对比 XC3090A (anti-fuse variant))

设计说明

The XC3090L-6TQG176C requires a clean 3.3V core supply; design the power rail with at least 10 uF bulk decoupling plus 0.1 uF high-frequency bypass per VCC pin pair. Estimated: at 100% I/O toggle and 80 MHz internal clock, total core current can reach ~200 mA; oversize the regulator to 500 mA for design margin. Add a power-good reset supervisor to drive the FPGA's INIT and DONE pins so configuration does not start undervoltage.

Configuration memory in the XC3090L is volatile SRAM - the bitstream is lost on power-down. Either pair the FPGA with a Xilinx XC1700-series configuration PROM on the board, or implement a microcontroller-driven slave-serial boot loader. Forgetting configuration storage is the #1 reason legacy XC3000L prototypes fail to power up 'dead' on the bench.

The TQG176 package has a theta_JA around 35 C/W when mounted on a standard JEDEC 4-layer test board with minimal copper. At commercial ambient +70C and ~200 mA core current (0.66W dissipation), the junction temperature stays well below 100C. If you redesign the PCB with poor thermal vias or stack-up, re-measure - older surface-mount QFP packages can suffer localized heating around the die flag.

Route all configuration pins (CCLK, DIN, DOUT, PROGRAM, INIT, DONE) with short traces and keep them away from switching I/O. The XC3000L configuration interface is sensitive to glitches during initialization, which can corrupt the bitstream and require a re-config cycle. Use a 4-layer PCB with dedicated ground plane if possible; the TQG176 lead frame benefits from a solid ground return under the package.
