XC3090L-7TQG176I - 3200 Gates FPGA, 176-pin TQG, -40C to +100C | Xilinx
The Xilinx XC3090L-7TQG176I is a member of the XC3000L Low-Voltage Logic Cell Array FPGA family, integrating approximately 3200 usable gates in a 176-pin Thin Quad Gulp (TQG) plastic surface-mount package. It is the low-voltage (3.3 V Vcc core) evolution of the original 5 V XC3000 family, designed for portable and power-sensitive digital logic designs. The -7 speed grade and -I industrial temperature range (-40C to +100C) suffix make this part suitable for harsh-environment industrial, telecom, and embedded controller applications. A Field-Programmable Gate Array (FPGA) is a semiconductor integrated circuit that can be configured by the customer after manufacture to implement arbitrary digital logic. FPGAs sit at the top of the programmable logic hierarchy, above CPLDs, and below structured ASICs. The XC3000L family belongs to the very first generation of SRAM-based Look-Up-Table (LUT) FPGAs, where each Configurable Logic Block (CLB) contains a small LUT and a flip-flop. Compared to modern 7 nm FPGAs, the XC3000L is severely resource-limited but remains valuable as a low-cost glue-logic substitute, a maintenance replacement for legacy boards, or a teaching vehicle for classic HDL synthesis flows. Key features of the XC3090L include 100 Configurable Logic Blocks (CLBs) yielding 3200 usable gates, 144 dedicated flip-flops, 176 user I/O pins, and on-chip distributed SelectRAM. The device is fabricated on a 0.6 um CMOS SRAM process and is in-system programmable via a standard JTAG (IEEE 1149.1 boundary-scan) interface or the legacy Xilinx XACT parallel configuration port. It supports 3.3 V core and 3.3 V/5 V tolerant I/O, making it a drop-in logic upgrade for boards originally populated with the 5 V XC3090. Typical applications span industrial control logic, legacy telecom backplane glue logic, prototyping and education platforms, and aerospace test equipment retrofits where long-term parts continuity and the Xilinx XACT toolchain still hold value. Designers transitioning a design from the 5 V XC3090 to the XC3090L benefit from lower power consumption and reduced heat dissipation while keeping the same architectural footprint and development flow.
XC3090L-8PC84BKJ - XC3000L 5V FPGA 84-Pin PLCC | AMD Xilinx
The AMD Xilinx XC3090L-8PC84BKJ is a member of the XC3000L Low-Voltage Logic Cell Array family, integrating 6K usable gates and 320 logic cells in a 84-pin PLCC (J-Lead) package. It operates from a 3.0V to 3.6V low-voltage supply, making it suitable for portable and battery-powered designs where 5V operation is impractical. The '8' speed grade specifies a nominal 70 MHz internal toggle rate within the XC3000L architecture family. An FPGA (Field Programmable Gate Array) is a reconfigurable semiconductor device that allows designers to implement arbitrary digital logic by programming an on-chip interconnect of configurable logic blocks (CLBs) and input/output blocks (IOBs). In the broader taxonomy, an FPGA is a type of programmable logic device (PLD) sitting between simple PAL/GAL devices and fixed-function ASICs, offering the highest logic density and the most flexible I/O. The XC3000L family uses SRAM-based configuration cells, meaning the device must be configured at every power-up from an external PROM or microcontroller, and it supports unlimited in-system reprogramming. Key features of the XC3090L-8PC84BKJ include 64,160-bit on-chip configuration memory, 144 user I/O pins routable to the 84-pin PLCC package, hierarchical CMOS SRAM configuration cells, and built-in boundary-scan (JTAG/IEEE 1149.1) support for board-level testability. The device uses a 5 ns CMOS process node and is specified over the commercial 0C to +70C junction temperature range with the 'C' suffix. Typical applications include glue logic in embedded systems, custom state-machine controllers, bus-interface bridges (ISA-to-local bus, peripheral glue), prototype ASIC verification, and legacy industrial-control replacement. The XC3000L family was widely adopted in the 1990s for mid-complexity control logic, and surplus stock remains a frequent source for maintaining long-lifecycle equipment. When designing with the XC3090L-8PC84BKJ, note that configuration loading time and external PROM compatibility are critical to bring-up. Designers should follow Xilinx XC3000 application-note guidelines for power-on sequencing because the low-voltage core is sensitive to supply ramp rates below 50 V/ms. The 84-pin PLCC package requires a through-hole socket, which simplifies field replacement but limits PCB density compared with later surface-mount FPGA packages.
XC3090L-8PC84C - 320-Cell XC3000 FPGA | AMD Xilinx | 84-PLCC
The AMD Xilinx XC3090L-8PC84C is a 3.3 V low-power Field Programmable Gate Array (FPGA) from the legacy XC3000A/L family, delivering 6,000 usable gates, 320 logic cells, and a maximum toggle frequency near 80 MHz in an 84-pin Plastic Leaded Chip Carrier (PLCC, J-lead) package. It is rated for commercial temperature operation (suffix "C"), with the speed grade "-8" indicating the slowest of the XC3000 family timing grades at 3.3 V supply. The device carries 70 user I/O and 64,160 bits of configuration memory. A Field Programmable Gate Array (FPGA) is a semiconductor integrated circuit built from a matrix of configurable logic blocks (CLBs) interconnected by programmable routing, surrounded by user-controllable I/O cells. FPGAs belong to the programmable logic hierarchy: programmable logic -> FPGA -> SRAM-based FPGA -> SRAM-LUT FPGA -> ASIC prototyping platform. Unlike microcontrollers, FPGAs implement hardware-level parallelism, executing logic in dedicated silicon gates rather than sequential firmware instructions. Key features of the XC3090L-8PC84C include 70 user I/O pins with TTL-compatible drivers, an on-chip oscillator for self-clocking configuration modes, JTAG-compliant boundary-scan testing support per IEEE 1149.1, and readback capability for in-system verification. The "L" suffix denotes the 3.3 V low-power variant, which reduces quiescent current versus the original 5 V XC3090 and simplifies migration to 3.3 V system rails. Architecturally, the XC3090L uses a five-input look-up table (LUT) per CLB with a distributed SRAM configuration store. Designs are captured as schematic netlists or VHDL/Verilog and compiled with the legacy XACTstep M1 toolchain, then programmed via the Xilinx HW-130 programmer or compatible JTAG loaders. The 84-PLCC footprint supports hand-soldering and socketed prototyping on through-hole boards. Typical applications include legacy industrial control interfaces, telecom line-card glue logic, ASIC prototyping for low-density glue functions, and educational FPGA laboratory platforms where students learn Verilog/VHDL design on classic SRAM-LUT silicon. The XC3090L is also used as a drop-in form factor for retrocomputing and test equipment maintenance. When designing with the XC3090L-8PC84C, designers must source the original XACTstep M1 development software, a parallel-port programmer, and acknowledge that the device is no longer in active production; lifecycle status should be confirmed before any new design commitment, and a long-term obsolescence mitigation plan is recommended. This page synthesizes distributor pricing, drop-in equivalent options, and practical design notes - engineering context that complements the legacy Xilinx datasheet but does not replace it.
XC3090L-8PC84I - XC3000 FPGA 6K Gates 320 Cells 80MHz | Xilinx
The Xilinx XC3090L-8PC84I is a member of the XC3000 family of Field Programmable Gate Arrays (FPGAs), offered in an 84-pin Plastic Leaded Chip Carrier (PLCC) package with J-lead terminations. The device contains 6,000 usable gates organized into 320 Configurable Logic Blocks (CLBs), supported by 64,160 configuration program-store bits, and operates at a maximum toggle frequency of 80 MHz from a 3.3 V core supply. The "L" suffix denotes the low-voltage 3.3 V variant of the original 5 V XC3090, and the "I" suffix indicates the industrial operating temperature grade of -40 °C to +85 °C. A Field Programmable Gate Array (FPGA) is a semiconductor integrated circuit built around an array of configurable logic blocks, programmable interconnect, and programmable I/O blocks, all of which are defined by a user-loaded configuration bitstream. FPGAs sit at the top of the programmable logic hierarchy, above simple PLDs and CPLDs, and are used as flexible digital platforms ranging from glue logic and bus interfacing to complete processor cores and signal-processing pipelines. The XC3000 series, introduced by Xilinx in the late 1980s, was the company's first commercially successful FPGA family and established the SRAM-based configuration architecture that subsequent generations continued to use. Key features of the XC3090L-8PC84I include 70 user I/O pins distributed around the perimeter, an internal configuration program store that holds the user-defined logic, and per-IOB input-threshold programmability so that each I/O can be configured for TTL or CMOS compatible external signaling. The global input buffer threshold, plus per-pin output drive controls, allow direct interfacing with mixed-logic voltage domains without external level shifters. The 80 MHz toggle rate and deterministic routing make the part well suited to glue logic, state-machine controllers, and parallel bus interfaces in industrial embedded systems. Architecturally, the device combines a perimeter of I/O Blocks (IOBs), a core matrix of Configurable Logic Blocks (CLBs), and a programmable interconnect network. Each CLB contains a small combinational look-up table, storage, and carry logic, while the IOBs include input threshold detection, output drivers, and registers. Configuration is loaded into the on-chip SRAM program store at power-up from an external PROM or microprocessor, which means the design is volatile and must be reloaded after every power cycle - a defining characteristic of the XC3000 family and a key consideration when selecting this part for new designs. Typical applications for the XC3090L-8PC84I include legacy industrial-control boards, telecommunications line cards, test-and-measurement fixtures, and digital glue logic on custom hardware where it replaces discrete TTL or 4000-series CMOS. Because it is a mature, widely understood device with abundant reference designs, it is also used by engineers maintaining long-lifecycle systems in factory automation and military/aerospace subsystems where re-qualification of newer FPGAs would be prohibitively expensive. Designers should be aware that the XC3000 family has been End-of-Life for many years, and active new designs are generally not supported by current Xilinx/AMD Vivado toolchains. When designing in this part, allow for configuration time at power-up (the bitstream must be loaded from an external source), provide proper decoupling on the 3.3 V supply, and respect the 84-pin PLCC J-lead land pattern exactly - the package is not pin-compatible with modern leadless FPGA packages. If a long-term or new design is being started, evaluate Spartan-6, Spartan-7, or MAX II/10 CPLD families as migration paths with HDL portability, while preserving the XC3090L-8PC84I for existing maintenance. This page synthesizes distributor pricing, drop-in same-package alternatives from the XC3000 family, and practical design notes not consolidated on the manufacturer datasheet alone.
XC3090L-8PCG84C - 84-Pin PLCC FPGA | Xilinx XC3000 Family
The AMD/Xilinx XC3090L-8PCG84C is a member of the XC3000A/L series of Field Programmable Gate Arrays (FPGAs) housed in an 84-pin Plastic Leaded Chip Carrier (PLCC, J-Lead) package. The device integrates approximately 70 Configurable Logic Blocks (CLBs) and 64,160 bits of configuration program store (often referred to as 6,400 gates), with 70 user I/O pins available on the 84-pin PLCC footprint. An FPGA (Field Programmable Gate Array) is a type of programmable logic device (PLD) that combines the high integration density of a gate array with user-defined configuration stored in on-chip SRAM. Within the broader component taxonomy, the XC3090L belongs to: FPGA -> programmable logic device -> logic IC -> integrated circuit -> semiconductor. The XC3000 family pioneered the use of a perimeter of I/O Blocks (IOBs), a core array of CLBs, and dedicated interconnect resources, an architecture that remains the conceptual ancestor of every modern SRAM-based FPGA. The XC3090L is the low-voltage ('L' suffix) variant of the XC3090, optimized for 3.3V operation to reduce power consumption versus the original 5V XC3090. The '-8' speed grade indicates a moderate performance tier within the family, and 'PCG84C' denotes the 84-pin Plastic Leaded Chip Carrier (PLCC) package with commercial temperature rating (0C to +70C). The device also provides built-in configuration logic supporting serial and parallel master/slave modes, plus boundary-scan testability via JTAG/IEEE 1149.1. The architecture comprises a symmetrical array of CLBs surrounded by programmable IOBs. Each CLB contains a combinatorial logic section, two flip-flops, and routing resources, while each IOB supports a wide range of input/output standards. Distributed throughout the die are 3-state buffers and on-chip wide-edge decoders that allow the implementation of wide AND-OR-INVERT gates directly in silicon. Typical applications include glue logic replacement, legacy industrial control, telecom interface boards, and educational/prototyping systems that target the classic Xilinx XC3000 design flow. The 84-pin PLCC package is socket-friendly and is therefore favored for through-hole prototype boards and field-upgradeable modules. The device is supported by the legacy XACT and early ISE Foundation toolchains. When designing with the XC3090L-8PCG84C, ensure that the 3.3V low-voltage supply rail is decoupled close to the device and that configuration mode pins (M0, M1, M2) are tied to the proper levels for the chosen programming source. Boundary-scan and readback features are particularly valuable for in-system verification on telecom and industrial boards. This part is now considered legacy/last-time-buy by Xilinx and is widely available only through aftermarket distributors.
XC3090L-8PCG84I - XC3000L FPGA 6K Gates 84-PLCC | Xilinx
The Xilinx XC3090L-8PCG84I is a member of the XC3000L Low-Voltage Field Programmable Gate Array family, delivering 6,000 usable gates, 320 configurable logic blocks (CLBs), and 70 user I/O pins in a 3.3 V, 84-pin PLCC package. It operates with a maximum toggle rate of approximately 80 MHz and is offered in an industrial-grade temperature rating (the 'I' suffix) for designs that must survive -40 °C to +85 °C ambient conditions. The '8' speed grade places it in the higher-performance segment of the XC3000L family, while the 'L' designation identifies it as the low-voltage 3.3 V variant rather than the 5 V XC3000/XC3100 line. The 84-pin PLCC footprint (package code PCG84) uses a J-leaded ceramic-compatible plastic carrier suitable for through-hole PCB assembly, and the device is supported by the legacy Xilinx XC3000 design flow including the XACT development system. A Field Programmable Gate Array (FPGA) is a semiconductor integrated circuit containing an array of configurable logic blocks, programmable interconnect, and configurable I/O cells that the user programs after manufacture to implement custom VLSI design tasks. Within the power management and digital logic hierarchy, an FPGA sits above fixed-function Application-Specific Integrated Circuits (ASICs) and below software-defined processors; it offers hardware-level parallelism, hardware-timed determinism, and reconfigurability that distinguishes it from microcontrollers. The XC3000 generation represents one of the earliest commercially successful SRAM-based FPGA architectures, forming the foundation from which later Xilinx families (XC4000, Spartan, Virtex, and 7-series) were developed. The 'L' low-voltage variant extends that legacy into battery-powered and 3.3 V-only systems where the original XC3000A 5 V supply could not be tolerated. Key features include 6,000 usable gates, 320 CLBs, 70 user I/Os, an 80 MHz toggle rate, and 3.3 V single-supply operation. A perimeter of user-programmable I/O blocks (IOBs) supports TTL and CMOS signalling levels, while the on-chip configuration memory retains the user's bitstream in SRAM that is reloaded at every power-up. The architecture is built around three types of configurable elements: IOBs, CLBs, and the programmable interconnect matrix that joins them. Typical applications include custom VLSI prototyping, TTL and MSI logic replacement, glue-logic consolidation on legacy 5 V/3.3 V mixed boards, industrial control glue logic, telecommunications interface adaptation, and educational FPGA lab kits that still depend on the XC3000 development flow. The industrial temperature grade makes it acceptable for factory-floor controllers, outdoor telecom line cards, and ruggedised test fixtures where commercial-grade parts would fail. When designing with the XC3090L-8PCG84I, remember that the configuration bitstream is volatile: the device must be reconfigured from an external EPROM or microcontroller at every power-up. The 84-pin PLCC package leaves only 70 pins available as user I/O, so pin budgeting must account for the dedicated clock, configuration, and boundary-scan pins before committing a logic design. Designers migrating from this part should evaluate modern Xilinx 7-series or Spartan-6 drop-in equivalents, but be aware that the footprint, configuration interface, and tool flow are not bitstream-compatible. This page synthesises distributor pricing, drop-in 84-pin PLCC alternatives within the XC3000L family, comparison data, and practical design notes that are not collated in any single manufacturer datasheet.
XC3090L-8TQ144C - 320 CLB FPGA, 80MHz, TQFP-144 | Xilinx
The Xilinx XC3090L-8TQ144C is a CMOS Field Programmable Gate Array from the legacy XC3000 family, offering 320 Configurable Logic Blocks (CLBs) and approximately 5000 equivalent gates with a maximum usable gate count of 6000. Housed in a 144-pin Thin Quad Flat Pack (TQFP) package, it operates at system clock rates up to 80 MHz with combinatorial CLB delays as fast as 6.7 ns and guaranteed flip-flop toggle rates between 190 and 370 MHz. The device is rated for a 3.0 V to 3.6 V supply, with 8 mA sink and 8 mA source output drive and quiescent current limited to 5 mA in power-down mode. A Field Programmable Gate Array (FPGA) is a semiconductor device built around an array of programmable logic blocks interconnected by a configurable routing matrix. Within the broader taxonomy, an FPGA sits as a subclass of programmable logic devices alongside CPLDs and falls under the digital IC hierarchy in power management and logic categories. The XC3000 series pioneered SRAM-based configuration and is positioned as the ancestor of all modern Xilinx FPGA families such as Spartan and Virtex. The "L" suffix designates the low-power CMOS process node, while the "-8" speed grade places this die at the high end of the XC3090's 1.55 to 4.1 ns logic-delay range. Key architectural features include 100% pin-out and architecture compatibility across the XC3000A/L and XC3100A/L families, allowing designers to migrate between density points without re-laying-out the board. The device supports JTAG-style boundary-scan testing and uses a distributed RAM/ROM programming model that loads the bitstream from external PROM at power-up. The TQFP-144 footprint exposes roughly 96 to 108 user I/O pins depending on bank configuration, with eight global clock buffers for high-fanout nets. Typical applications include glue-logic replacement in legacy industrial controllers, prototyping platforms for ASIC emulation, and digital signal pre-processing in telecom backplanes. The combination of 5000 gates and 80 MHz system clock is well-suited to state-machine controllers, UART bridges, FIFO address generators, and parallel-to-serial converters that were popular in 1990s-era designs still in long-life service today. When designing with this part, note that configuration requires a serial or parallel EPROM and at least four configuration mode pins. The 5 mA quiescent current makes it acceptable for battery-backed applications, but designers must respect the 3.6 V absolute-maximum supply rating to avoid latch-up. JTAG boundary scan is supported, but in-system reconfiguration requires careful handling of the DONE and INIT pins. This page synthesizes distributor stock and pricing snapshots from DigiKey, Mouser, Octopart and the Xilinx product archive, plus drop-in same-family variants from the XC3000A/L and XC3100A/L families — practical sourcing context not consolidated on any single manufacturer page.
XC3090L-8TQ144I - 6K-Gate CMOS FPGA, 80 MHz, 144-TQFP | Xilinx
The Xilinx XC3090L-8TQ144I is a CMOS Field Programmable Gate Array from the XC3000L family, delivering 320 Configurable Logic Blocks (CLBs), 6000 maximum usable gates, and a 5000-gate nominal equivalent count in a 144-pin TQFP (TQ144) surface-mount package. The device operates from a 3.3 V supply, supports system clock rates of 50 to 85 MHz, and provides guaranteed flip-flop toggle rates from 190 to 370 MHz with logic delays between 1.55 and 4.1 ns. A Field Programmable Gate Array (FPGA) is a semiconductor integrated circuit composed of an array of programmable logic blocks interconnected by a configurable routing matrix. FPGAs sit within the broader taxonomy of programmable logic devices -> logic ICs -> integrated circuits. The XC3000 series from Xilinx is one of the earliest commercially successful SRAM-based FPGA architectures, predating modern families such as Spartan and Artix, and remains relevant for long-lifecycle industrial, military, and legacy retrofit designs. Key electrical characteristics include 8 mA output sink and source drive capability, a maximum quiescent current of 5 mA during power-down, and full architecture and pin-out compatibility with sibling XC3000A/L and XC3100A/L devices. The 'L' suffix denotes a low-voltage 3.3 V core supply, while the 'I' suffix indicates the industrial -40 C to +85 C operating temperature grade and the '8' speed grade defines the timing bin. Architecturally, the XC3090L uses a symmetrical 22 x 22 CLB matrix with on-chip distributed interconnect, tri-state buffers on every I/O, and dedicated global clock buffers. The device is configured at power-up from an external serial or parallel PROM (e.g., XC1736, XC1765), and configuration bitstreams are identical in pinout across the XC3000L and XC3100L families, easing migration. Typical applications include industrial control glue logic, legacy telecommunications backplane interfaces, test-and-measurement instrumentation, and aerospace retrofits requiring pin-compatible drop-in replacements for end-of-life XC3000 designs. The XC3090L-8TQ144I is well suited to low-to-medium complexity glue logic, bus interfacing, and state-machine control where non-volatility, in-system reprogrammability, and 3.3 V operation are required. When designing with this device, ensure the configuration interface (mode pins M0/M1/M2 and DONE) is properly terminated, and that decoupling includes a 0.1 uF and 10 uF capacitor pair adjacent to every VCC/ground pair. Long-lifecycle users should also note that this part is mature silicon and is best sourced from authorized distributors or franchised brokers with full traceability. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found on the manufacturer datasheet alone.
XC3090L-8TQ176C - 6K-Gate 80MHz CMOS FPGA | Xilinx TQFP-176
The Xilinx XC3090L-8TQ176C is a 5,000-gate (6,000-gate maximum) CMOS Field Programmable Gate Array from the legacy XC3000A/L family, supplied in a 176-pin TQFP package. It features 320 Configurable Logic Blocks (CLBs), operates at a maximum clock frequency of 80 MHz, and is rated for 3.3 V core operation. The 'L' suffix denotes the low-voltage variant; the '8' speed grade corresponds to the slowest timing bin, and '176C' identifies the commercial-temperature TQFP-176 package option. A Field Programmable Gate Array (FPGA) is a semiconductor IC whose logic function and interconnects are defined by configuration data loaded into on-chip static memory. FPGAs sit within the broader hierarchy programmable logic device -> programmable logic -> logic IC -> integrated circuit, and historically served as the fastest path to custom digital logic before modern HDL-based ASIC flows became mainstream. The XC3000 family pioneered SRAM-based configuration, allowing infinite reconfiguration and rapid prototyping cycles that defined early-1990s digital design. Key specifications include 5,000 usable gates (6,000 max), 320 CLBs, 80 MHz maximum toggle frequency, 3.3 V VCC, SRAM-based configuration, JTAG boundary-scan support, and a 0.500 mm pitch TQFP-176 footprint. The device exposes dedicated I/O blocks with programmable pull-ups and output slew-rate control, and it supports multiple configuration modes including master serial, slave serial, and peripheral modes for flexible system boot. Technically, the XC3090L uses a 5 V-tolerant I/O architecture on a 3.3 V core, with CMOS process geometry typical of mid-1990s Xilinx silicon. Each CLB contains a configurable combinatorial logic section plus two flip-flops, with local interconnect feeding the general-purpose routing matrix. The 80 MHz grade represents worst-case pin-to-pin combinatorial delay across the slowest paths, adequate for glue logic, bus interfacing, and state-machine replacement rather than high-throughput DSP. Typical applications include legacy glue-logic replacement, bus-bridge adapters (e.g., ISA-to-local-bus converters), industrial controller front-ends, and educational FPGA platforms where the TQFP-176 footprint is already laid out. The XC3090L is widely used as a pin-compatible replacement target for systems designed around the XC3000 family pinout. When designing, verify that the configuration memory source (EPROM, EEPROM, or microcontroller) matches the selected configuration mode and that the readback/special I/O voltage levels do not exceed the absolute-maximum ratings. Always reference the Xilinx XC3000 family datasheet for full timing parameters. This page consolidates distributor availability, parametric data, drop-in alternatives, and practical design notes that supplement the original Xilinx XC3090L datasheet.
XC3090L-8TQ176I - 5000 Gates FPGA, 320 CLBs, 80 MHz | Xilinx
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.
XC3090L-8TQG176C - 320 CLB FPGA, 6K Gates, 80MHz, TQFP-176 | Xilinx
The Xilinx XC3090L-8TQG176C is a 3.3 V, low-voltage CMOS Field Programmable Gate Array from the Xilinx XC3000L Logic Cell Array family, packaged in a 176-pin Thin Quad Flat Pack (TQFP). It contains 320 Configurable Logic Blocks (CLBs), delivers approximately 5,000 equivalent gates (with up to 6,000 usable gates), and supports system clock rates up to 80 MHz. What is an FPGA? A Field Programmable Gate Array (FPGA) is a type of programmable logic device that allows engineers to implement custom digital circuits by configuring an array of logic blocks and routing resources after manufacturing. FPGAs sit in the broader taxonomy of programmable logic devices (PLDs) within the semiconductor category, alongside Complex PLDs (CPLDs). They differ from CPLDs in architecture: FPGAs use a fine-grained array of look-up tables (LUTs) and SRAM-based configuration memory, offering higher logic density and richer register-rich datapaths, while CPLDs use macrocell-based, non-volatile architectures optimized for glue logic and fast pin-to-pin combinational delays. The Xilinx XC3000L family specifically targets low-voltage (3.3 V), high-volume designs where predictable timing and low power are required. Key features of the XC3090L-8TQG176C include 320 CLBs organized in a symmetric array, on-chip SRAM-based configuration memory (reprogrammable in-system), TTL-compatible I/O, and the -8 speed grade. The -8 speed grade corresponds to a slower timing bin, trading absolute clock frequency for lower cost; faster -6 and -7 bins are also offered in the same family. The device is configured externally from an EEPROM, EPROM, ROM, or disk file, with on-chip initialization logic handling the configuration handshake. Typical applications span legacy industrial control boards, telecommunications glue logic, prototyping of state machines and bus interfaces, and design migration from discrete TTL/CMOS MSI logic to a single programmable device. The TQFP-176 footprint is widely accepted for through-hole-era replacements and older PCI and ISA-style add-in cards where surface-mount assembly is feasible but BGA is not yet adopted. When designing with the XC3090L-8TQG176C, note that the part is in long-term EOL and should be qualified against remaining distributor stock before any new design-in.

The Xilinx XC3090L-8TQG176I is a CMOS Field Programmable Gate Array from the legacy XC3000L low-voltage family, offering approximately 5000 usable gates (up to 9000 equivalent system gates) implemented across 320 Configurable Logic Blocks (CLBs) in a 176-pin TQG/LQFP package. It supports a maximum clock frequency of 80 MHz with a CLB combinatorial delay of 6.7 ns at the -8 speed grade, targeting high-density glue-logic, prototyping, and industrial control applications where ASIC-class integration is not yet justified. What is an FPGA? A Field-Programmable Gate Array is a reconfigurable digital integrated circuit whose logic fabric and interconnect can be programmed by the end user after manufacture. Within the taxonomy of digital ICs, an FPGA sits between an Application-Specific Integrated Circuit (ASIC) and a microcontroller: an ASIC is hard-wired for one function but offers the lowest unit cost at high volume, while an FPGA trades per-unit cost for design flexibility, parallel hardware execution, and rapid time-to-market. The XC3000 family pioneered SRAM-based configuration and the now-universal island-style CLB + IOB + programmable interconnect architecture that defines the modern FPGA. Key features of the XC3090L-8TQG176I include on-chip SRAM-based configuration store, three types of configurable elements (perimeter I/O Blocks, core CLB array, and routing channels), industrial-grade -40C to +85C operating range (I suffix), and the low-voltage L-suffix core that reduces 5V-family power. The device is housed in a 176-terminal LQFP/TQFP package on a 0.5 mm pitch with gull-wing leads suitable for surface-mount assembly and rework. Technically, the XC3000L family uses a 5V-tolerant I/O structure with 3.3V or 5V core options, hierarchical interconnect including long lines, hex lines, and direct connects, and configurable IOBs that support registered, latched, or combinatorial I/O with tri-state control. The architecture integrates a configuration program store so the array can be re-programmed in-system via the standard Xilinx configuration interface. Typical applications span industrial control systems, telecommunications glue logic, prototyping platforms for ASIC emulation, test and measurement fixtures, military/aerospace subsystems, and educational development kits where students learn HDL synthesis on a mature, well-documented device family. The TQG176 package is the highest-density option for this die. When designing with the XC3090L-8TQG176I, note that this device family is mature (introduced in the early-to-mid 1990s), so verify long-term availability and second-source supply before committing new production designs. New designs should weigh migration to the Xilinx CoolRunner-II CPLD or Spartan-6/Spartan-7 FPGA families for active lifecycle status and modern toolchain support.

The XC3000 family is the third-generation Xilinx architecture that introduced distributed Configurable Logic Blocks with look-up table-based logic, complemented by a programmable interconnect matrix and I/O blocks. Key features of the XC3090LTM-100PC84C include 320 CLBs, a typical gate count range of 5,000 to 6,000 gates, 100 MHz system performance, and 5V CMOS core technology. The PLCC-84 (PC84) package uses J-lead surface-mount terminals in a square ceramic/plastic body, supporting legacy through-hole-style PCB assembly processes. The XC3000 family pioneered SRAM-based configuration, allowing infinite re-programmability via an external configuration PROM or microcontroller bitstream load. From an architecture perspective, the XC3000L family uses 5V-tolerant I/O buffers, distributed RAM capability in select CLB modes, and a hierarchical interconnect that routes signals between logic blocks with predictable delay. The 'LTM' suffix designates the low-voltage / commercial temperature variant in the XC3000 family. Compared with modern 28nm or 16nm FPGAs, the XC3090LTM-100PC84C delivers modest logic density but remains useful for legacy board retrofits, education platforms, and industrial systems where proven long-life silicon is required.

When designing with this device, ensure proper configuration circuitry is included - the SRAM-based XC3000 family requires a configuration bitstream at every power-up. Plan for 5V supply decoupling, and verify I/O voltage compatibility with downstream CMOS or TTL peripherals. Engineers targeting new designs should consider the device's NRND/EOL status and confirm lifetime-buy availability for production runs.

Within the broader semiconductor taxonomy, an FPGA belongs to programmable logic devices (PLDs), which sit between fixed-function ASICs and discrete logic ICs in flexibility and integration. The XC3000L family was Xilinx's third-generation low-voltage FPGA line, succeeding the original XC3000 by operating from 3.0 V to 3.6 V supplies instead of 5 V, enabling lower power consumption for portable and battery-powered designs of the 1990s. Key features include 320 CLBs, 928 flip-flops, 138 user I/Os, 4.75 V to 5.25 V supply range for the I/O bank, an internal 3.3 V core, and a 125 MHz maximum toggle/clock frequency. The device supports JTAG-based boundary-scan testing, on-chip configuration memory, and tri-state output buffers per I/O. The PLCC-84 through-hole package provides robust mechanical mounting suitable for industrial and legacy equipment designs. Technically, the XC3090LTM-125PC84C uses SRAM-based configuration cells, meaning the bitstream must be loaded from an external ROM or microcontroller at every power-up. This volatile configuration enables unlimited re-programming cycles in the field, but requires a separate configuration PROM such as the XC1736 or compatible serial-loader device. The architecture implements a symmetrical array of CLBs surrounded by perimeter I/O blocks (IOBs), which was the industry-standard FPGA floorplan of that era. Typical applications include industrial control logic, telecom interface glue logic, legacy peripheral adapters, and test-and-measurement custom instrumentation. The wide I/O count (138) supports parallel buses and high-pin-count glue-logic designs. When designing with this FPGA, allocate at least 4 clock-pad pins for global clock distribution and ensure the configuration PROM timing aligns with the XC3090LTM power-on reset sequence. For new designs, consider migrating to a modern Xilinx 7-series or Spartan-6 device, since the XC3000L family is no longer recommended for new designs.

Once configured, the FPGA behaves as a dedicated custom digital circuit. The XC3000 family was Xilinx's pioneering commercial FPGA line, establishing the FPGA architecture still dominant in the industry today, and the XC3000L variant extends that architecture to lower-voltage 3.3 V systems where power dissipation is a primary concern. Key features of the XC3090LTM-8PC84C include approximately 320 Configurable Logic Blocks (CLBs), 64,160 bits of distributed configuration memory, and an 84-pin PLCC package with J-lead surface-mount terminations. The device supports in-system configuration via the Xilinx XC3000 configuration bitstream and is footprint-compatible with other XC3090L members that share the PC84 pinout. Logic delays are typically in the 5-10 ns range, sufficient for moderate-speed glue logic, bus interfacing, state-machine implementation, and small processor prototyping on 3.3 V rails. Typical applications include legacy 3.3 V digital glue logic replacement, prototype ASIC emulation, custom peripheral interfacing for microcontrollers, parallel bus arbitration, and industrial control subsystems where 5 V FPGAs are no longer acceptable. The 84-PLCC package also supports through-hole and socket-based prototyping, which is convenient for engineering development and low-volume production. Designers should note that the XC3000L family is legacy silicon - the Xilinx WebPACK and modern Vivado tools do not support these devices. Programming requires the legacy XACT or older Foundation toolchains, and configuration bitstreams generated for XC4000, Spartan, or 7-series FPGAs are incompatible. Engineers maintaining legacy systems should verify the configuration PROM and toolchain availability before committing to new designs.
