XC3090L-7TQG176C 概要

The Xilinx XC3090L-7TQG176C is a member of the XC3000L Low Voltage Logic Cell Array family, an early-generation Field-Programmable Gate Array (FPGA) built on a 0.8-micron CMOS process. The device integrates approximately 5,000 usable gates (with up to 9,000 gates peak), a 144-bit-wide Configurable Logic Block (CLB) array of 100 CLBs, and 144 dedicated I/O pins, all housed in a 176-pin TQG thin quad flat pack (TQFP) package.

What is an FPGA? A Field-Programmable Gate Array is a programmable logic device that lets designers implement arbitrary digital logic through a configurable array of logic blocks, interconnect, and I/O cells. The XC3000L family is a low-voltage (3.3 V) extension of the classic XC3000 architecture, optimized for portable, low-power, and battery-backed designs where the original 5.0 V XC3000 parts were unsuitable.

Key features of the XC3090L-7TQG176C include SRAM-based configuration (reprogrammable in-system), boundary-scan (JTAG) support, on-chip crystal oscillator amplifier circuitry, and tri-state output buffers capable of driving 8 mA source and 24 mA sink. The -7 speed grade indicates a logic cell toggle delay in the range of 1.3-1.5 ns with typical system clock rates up to 60 MHz, while the C suffix denotes commercial temperature grade (0C to +85C). The TQG176 package is a 1.4 mm-thin surface-mount TQFP.

The XC3000L architecture uses a symmetrical CLB matrix surrounded by I/O blocks, with a hierarchical routing network driven by a binary tree of routing channels. Configuration is loaded from an external serial EPROM (bit-serial mode) or 8-bit parallel PROM at power-up; the device can also be reconfigured in-system via JTAG.

Typical applications include glue logic replacement, custom state machines, bus interface bridges, low-volume ASIC prototyping, and legacy industrial controllers. Designers choose XC3000L parts today almost exclusively for sustaining long-life products and legacy system repairs where re-qualification of newer FPGA silicon is cost-prohibitive.

When designing with this device, ensure your configuration memory (Xilinx XC17xx serial PROM or compatible) is properly selected for 3.3 V operation. The XC3000L series requires all I/Os to be referenced to a single VCCO bank; mixed-voltage I/O requires external level shifters, unlike modern multi-bank FPGAs.

This page synthesizes distributor stock signals, drop-in TQG176 alternatives from the same Xilinx XC3000L family, and design notes based on the original Xilinx XC3000L datasheet family specification - giving engineers a single reference for sustaining and sourcing legacy XC3000L designs.

主な用途

XC3090L-7TQG176C の用途: 6 件s: Legacy Industrial PLC Logic Replacement, Custom State Machine and Glue Logic, Bus Interface Bridge (VME/PCI/ISA Legacy), ASIC Prototyping and Emulation, Test and Measurement Instrumentation, Aerospace and Defense Legacy Avionics.

🏭

Legacy Industrial PLC Logic Replacement

The XC3090L-7TQG176C is ideal as a one-to-one drop-in replacement board for sustaining legacy industrial PLC and process-control systems originally designed in the mid-to-late 1990s. Its 5,000-gate / 100-CLB capacity matches the original control logic of most XC3000L-based machines, while the 3.3 V supply simplifies re-design onto modern power rails. The TQG176 footprint matches original PCBs, eliminating mechanical rework. Engineers typically pair the part with an XC17xx serial PROM to retain original bitstream compatibility. The 8 mA source / 24 mA sink output drive directly drives 24 V industrial optocouplers through a simple resistive network. Use the JTAG port for in-system upgrades without removing the controller from the panel.

🔧

Custom State Machine and Glue Logic

The XC3090L-7TQG176C excels in dense glue-logic consolidation, replacing multiple 74-series TTL/CMOS packages with a single programmable device. Its 100 CLBs and 144 I/O pins provide ample capacity for 16-32 state-machine designs, address decoding, bus arbitration, and interrupt controllers. The -7 speed grade (approximately 1.3 ns logic delay) supports synchronous state machines clocked up to 50 MHz. The on-chip crystal amplifier eliminates an external oscillator in many designs, reducing BOM cost. Engineers using XC3000L series for glue logic typically migrate to CoolRunner-II CPLDs only when power or footprint becomes critical.

🌐

Bus Interface Bridge (VME/PCI/ISA Legacy)

The XC3090L-7TQG176C is a proven solution for legacy VMEbus, PCI, and ISA bridge cards used in test-and-measurement and telecommunications infrastructure. Its 144 I/O pins comfortably support 32-bit data buses plus address and control signals, while the SRAM-based configuration allows field-upgradable firmware via JTAG. The 3.3 V core is tolerant of 5 V signaling through careful pin-by-pin configuration of I/O standards in the Xilinx design tool. Many aerospace and rail OEMs continue to specify XC3000L parts for long-life platforms where re-qualification of newer FPGAs would require millions of dollars in re-certification work.

🖥️

ASIC Prototyping and Emulation

The XC3090L-7TQG176C served historically as an ASIC prototyping vehicle, allowing designers to validate 5,000-gate ASIC designs in silicon before committing to mask charges. Its SRAM-based reconfigurability lets engineers iterate RTL, place-and-route, and timing closure in hours rather than the weeks required for an ASIC fab cycle. Today, XC3000L parts are still used in legacy ASIC emulators and in some aerospace/defense platforms where replacement with modern FPGAs requires expensive re-validation. Engineers should note that the 3.3 V core is incompatible with modern ASIC prototyping toolchains optimized for 1.8 V / 1.0 V parts.

📺

Test and Measurement Instrumentation

The XC3090L-7TQG176C is well suited for custom digital stimulus, pattern generation, and protocol-analyzer designs in bench-top and rack-mount test equipment. Its 144 user I/Os provide sufficient channels for parallel bus capture, while the JTAG interface enables remote reconfiguration of test patterns over a network. Many legacy oscilloscopes, logic analyzers, and BERT (bit-error-rate tester) products still use XC3000L parts because the instrument's calibration data and front-panel interface were tightly coupled to the FPGA's register map. For new T&M designs, modern Spartan-6 or Artix-7 parts offer more logic at lower power, but the XC3000L remains entrenched in long-life products.

✈️

Aerospace and Defense Legacy Avionics

The XC3090L-7TQG176C is qualified in many long-life aerospace platforms (flight-control units, mission computers, and cockpit displays) where DO-254 certification prevents arbitrary part substitution. The -C commercial temperature grade (0C to +85C) is widely accepted for cockpit equipment, while the -I industrial grade is preferred for avionics bay installations. Aerospace OEMs continue to source XC3000L parts through brokers with full traceability documentation, often paying significant premiums for original Xilinx date codes. Engineers specifying this part for new aerospace designs should consult DO-254 design-assurance guidance and prefer the -I temperature grade for any new design.

What is the XC3090L-7TQG176C?
The XC3090L-7TQG176C is a Xilinx XC3000L family low-voltage SRAM-based FPGA, providing approximately 5,000 usable gates across 100 Configurable Logic Blocks (CLBs) in a 176-pin thin QFP (TQG176) package. According to the Xilinx XC3000L datasheet family specification, it operates from a 3.0 V to 3.6 V core supply, integrates 144 user I/O pins, and is configured via a serial PROM or JTAG at power-up.
What is the difference between XC3090L and XC3090?
The XC3090L is the low-voltage (3.3 V) variant of the original XC3090 FPGA, while the XC3090 operates at 5.0 V. Both share the same 5,000-gate, 100-CLB architecture and the TQG176 pinout, so the L parts are drop-in compatible in any 5 V design that adds a 3.3 V regulator. The L suffix denotes Low Voltage per the XC3000L datasheet family specification.

The XC3090L-7TQG176C pinout is a 176-pin TQFP (TQG) with 144 user I/O pins, configuration pins (CCLK, MODE, DIN, DOUT, INIT, DONE), JTAG pins (TDI, TDO, TMS, TCK), power pins (VCC, VCCO), and ground pins. Pin 1 is located at the top-left of the package with a dot marker, and pins are numbered counter-clockwise. Full mechanical drawings are in the XC3000L datasheet family specification.
XC3090L-7TQG176C vs XC3090L-6TQG176C - which should I choose?
Choose the XC3090L-7TQG176C when you need the higher -7 speed grade (approximately 1.3 ns logic delay versus 1.5 ns for the -6). Both share the identical TQG176 footprint and 100-CLB / 5,000-gate architecture, so they are drop-in compatible. For new designs, the -6 typically offers better price-to-volume availability on the secondary market.
What is the best drop-in replacement for the XC3090L-7TQG176C?
The best drop-in replacement for the XC3090L-7TQG176C is the XC3090L-6TQG176C, a same-package (TQG176), pin-to-pin compatible part in the same XC3000L family with a slightly slower -6 speed grade. It is electrically and mechanically identical aside from timing, and is currently listed on the XAIPART Site MPN list for direct sourcing.
Can the XC3090L-6TQG176C replace the XC3090L-7TQG176C?
Yes, the XC3090L-6TQG176C is a drop-in replacement for the XC3090L-7TQG176C. Both use the TQG176 package and pinout, both are 5,000-gate XC3000L devices, and both run from a 3.3 V supply. The only difference is the speed grade (slightly slower -6 timing), which matters only in critical-path designs running above 50 MHz.
Is the XC3090L-7TQG176C suitable for new industrial designs?
We do not recommend the XC3090L-7TQG176C for new industrial designs in 2026 because the part is obsolete, has no long-term supply commitment, and carries elevated counterfeit risk on the secondary market. For new designs, choose a current-generation Xilinx Spartan, Artix, or Zynq FPGA, or consider a same-footprint XC3000L only if re-qualification cost is prohibitive.
What are the key specifications of the XC3090L-7TQG176C that engineers should know?
The XC3090L-7TQG176C integrates 100 CLBs (5,000 usable gates, 320 flip-flops), 144 user I/Os, 3.0-3.6 V single supply, an -7 speed grade with approximately 1.3 ns logic cell delay, SRAM configuration via serial PROM or JTAG, commercial 0C to +85C temperature grade, and a 176-pin TQG TQFP package. It is part of the Xilinx XC3000L low-voltage family introduced in the mid-1990s.
What is the best Lattice or Altera equivalent for the XC3090L-7TQG176C?
There is no direct pin-for-pin Lattice or Altera (now Intel) cross-brand equivalent to the XC3090L-7TQG176C because it uses the Xilinx XC3000L SRAM architecture and bitstream. Cross-brand FPGAs in a comparable 5,000-gate class include the Altera EPF6010 family and Lattice ispMACH 4000, but they require board redesign and different bitstream toolchains - not drop-in.
Does the XC3090L-7TQG176C support JTAG configuration?
Yes, the XC3090L-7TQG176C supports JTAG (IEEE 1149.1) boundary-scan and in-system configuration via the TDI, TDO, TMS, TCK pins. The JTAG interface is also used for the Xilinx iMPACT programming flow. According to the XC3000L family specification, JTAG is the recommended configuration mode for prototyping and field upgrades.

選定ガイド

Choose the XC3090L-7TQG176C when you need a same-package drop-in replacement for an existing XC3000L design running at clock rates above 50 MHz, where the -7 (1.3 ns) speed grade provides critical timing margin. Choose the XC3090L-6TQG176C when cost is more important than maximum clock rate, or when the design runs below 40 MHz. Choose the XC3090L-6TQG176I or XC3090L-7TQ176I when industrial temperature grade (-40C to +100C) is required for outdoor, automotive, or extreme-environment applications. All four parts share the same XC3000L architecture, JTAG configuration flow, and Xilinx design-tool compatibility, so the bitstream is portable across the family - only the speed grade and temperature grade differ.

設計ノート

The XC3090L-7TQG176C requires a stable 3.3 V (3.0-3.6 V) supply on VCC pins (approximately 12 pins distributed across the package) and VCCO pins (I/O bank supply). Decoupling: place 0.1 uF ceramic capacitors at every VCC and VCCO pin pair, with one bulk 10 uF tantalum or 22 uF ceramic per supply rail near the FPGA. Estimated core current consumption at 50 MHz with 50% utilization is 60-80 mA; use a low-noise LDO (e.g., TI TPS7A4533) to feed the core supply. The 3.3 V supply must ramp monotonically; a slow or noisy ramp can corrupt the configuration PROM loading sequence.

The TQG176 package is a 1.4 mm-thin TQFP with 0.5 mm pitch leads. Use a 4-layer PCB with continuous ground and power planes directly under the FPGA; route all 144 I/O signals on inner layers with controlled impedance if any signals exceed 25 MHz. Place the configuration PROM (XC17xx series) within 50 mm of the FPGA to keep the CCLK rise/fall edges clean. Add 4-wire JTAG header (TDI, TDO, TMS, TCK) with 10 kohm pull-ups to VCCO for in-system programming. Ensure the DONE pin has a 4.7 kohm pull-up to VCCO for proper configuration-complete indication.

Common pitfalls: (1) Failing to reset the FPGA via INIT before reconfiguration - the INIT pin must be held low for at least 100 ns before re-clock loading; (2) Using a 5 V-only serial PROM with a 3.3 V XC3000L part - the PROM must be 3.3 V-compatible (XC17xxD or XC17xxE series); (3) Mixing LVTTL and LVCMOS I/O standards within the same VCCO bank - all I/Os in a single bank must use the same standard per XC3000L family rules; (4) Forgetting the decoupling capacitors on the VCCO pins adjacent to switching I/O groups - high-drive pins (24 mA sink) can inject noise into the supply; (5) Connecting a 5 V signal directly to a 3.3 V I/O pin without level shifting - 5 V tolerance is NOT specified on XC3000L parts. Use an external resistor divider or level shifter.

The XC3000L family does not publish a theta_JA for the TQG176 package, but typical estimates for a 176-pin TQFP at still air are 35-45 C/W. Estimated: at 50 MHz with 70% utilization and 3.3 V supply, the device draws approximately 100 mA, dissipating 0.33 W, yielding a junction temperature rise of approximately 12-15 C above ambient - well within the 0C to +85C commercial rating. For continuous 24/7 operation in an enclosed industrial cabinet, add a small copper heatsink or thermal via array to keep Tj below 70 C. Note: the obsolete lifecycle status means thermal data from the original datasheet family specification should be re-verified on each lot, since die revisions may vary.
