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.

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.

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. Designers should verify lead-free reflow compatibility (the original XC3000L family was specified for SnPb process), and confirm configuration mode (serial vs. parallel) against board-level pull-up resistors and DONE/PROG sequencing. This page synthesizes distributor stock levels, drop-in same-package XC3000L variants, and practical obsolescence-management notes not found in the original manufacturer datasheet.
XC3090L-8TQG176I - 9000 Gates FPGA, 80 MHz, 176-pin LQFP | Xilinx
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. This page synthesizes distributor pricing, XAIPART in-stock tiers, pin-compatible Xilinx drop-in alternatives drawn from the XC3000L family, and practical design notes on configuration, I/O banking, and legacy toolchain compatibility not found in the original datasheet.
XC3090LTM-100PC84C - 6K Gate, 320-Cell FPGA 5V 84-PLCC | Xilinx
The Xilinx XC3090LTM-100PC84C is a CMOS Field Programmable Gate Array (FPGA) from the legacy XC3000 Logic Cell Array family, delivering approximately 6,000 usable gates and 320 Configurable Logic Blocks (CLBs) in an 84-pin Plastic Leaded Chip Carrier (PLCC) package. Operating at 5V CMOS technology with a 100 MHz internal performance grade, the device is rated for commercial temperature conditions and targets low-voltage logic integration where fine-grained parallel logic is required. A Field Programmable Gate Array (FPGA) is a type of programmable logic device that combines the density of gate arrays with the design flexibility of in-system programmability. FPGAs sit at the top of the programmable logic hierarchy (PLD -> CPLD -> FPGA -> SoC FPGA) and are widely used to implement custom digital logic, glue logic, bus interfaces, and parallel datapaths without committing to a masked ASIC. 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. Typical applications include industrial control glue logic, legacy telecommunications interfaces, military and aerospace retrofits (through QML equivalents), educational FPGA training platforms, and digital signal preprocessing where low-cost parallel logic suffices. The 84-pin PLCC footprint is socket-compatible with the broader XC3000/XC3100/XC3300 84-pin PLCC family, simplifying board reuse across multiple design generations. 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. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet alone, providing a single reference for engineers evaluating the XC3090LTM-100PC84C for both new designs and legacy support scenarios.
XC3090LTM-125PC84C - 5000 Gates XC3000L FPGA, 125MHz, PLCC-84 | Xilinx
The Xilinx XC3090LTM-125PC84C is a 5000-gate, 125 MHz Field Programmable Gate Array (FPGA) from the legacy XC3000L Low-Voltage Logic Cell Array family, housed in an 84-pin Plastic Leaded Chip Carrier (PLCC-84) package. It delivers approximately 5000 equivalent gates, 320 Configurable Logic Blocks (CLBs), and 928 flip-flops, with a maximum clock frequency of 125 MHz. The 'L' suffix denotes the low-voltage 3.3 V core variant, and 'TM' indicates the commercial plastic-leaded chip carrier package grade. An FPGA (Field Programmable Gate Array) is a programmable logic device that lets engineers implement arbitrary digital logic functions using an array of configurable logic blocks (CLBs) interconnected by a programmable routing matrix. 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. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet.
XC3090LTM-8PC84C - XC3000L FPGA, 6K Gates, 84-PLCC | Xilinx
The Xilinx XC3090LTM-8PC84C is a member of the legacy XC3000L Low Voltage Logic Cell Array family, delivering approximately 6,000 usable gates in an 84-pin Plastic Leaded Chip Carrier (PLCC) package. The device is built on a 0.8-micron CMOS SRAM-based architecture and operates from a 3.0 V to 3.6 V core supply, with the "L" suffix designating low-voltage operation relative to the original 5 V XC3000 series. The "TM" suffix indicates a specific speed/grade combination within the XC3000L family. A Field Programmable Gate Array (FPGA) is a semiconductor device containing an array of configurable logic blocks (CLBs), programmable interconnects, and programmable I/O cells. The user-defined logic function is loaded into on-chip static memory cells from an external boot source such as an EEPROM, EPROM, ROM, or microprocessor. 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.

When designing with this FPGA, careful attention must be paid to power supply decoupling and configuration bitstream storage. The 1.2V core requires stable power, and the configuration data is typically stored in an external SPI flash, which must be selected for compatibility.
XC3S200-4FT256C - 200K Spartan-3 FPGA | AMD / Xilinx
AMD XC3S200-4FT256C is a Spartan-3 field-programmable gate array with 200000 system gates, 4320 cells, and a 256-LBGA package. The -4 speed grade operates at up to 630 MHz, while the device uses a nominal 1.2 V core supply and is manufactured in 90 nm process technology. These headline characteristics position the FPGA between fixed-function logic and larger programmable-logic devices for cost-sensitive, moderate-complexity embedded systems. A field-programmable gate array is a programmable logic device in which configurable logic blocks, programmable input/output blocks, and programmable interconnect form a user-defined digital circuit. Within the semiconductor hierarchy, an FPGA belongs to programmable logic devices, alongside CPLDs and mask-programmable logic. Unlike a fixed-function microcontroller or application-specific integrated circuit, an FPGA can be reconfigured after manufacture to implement control, interface, protocol, signal-processing, or security functions in parallel. The Spartan-3 architecture provides 480 configurable logic blocks and 4320 cells according to the supplied distributor and comparison data. Its 256-ball package supports 256 terminals for device configuration, power, clocking, and user I/O. The -4 designation identifies the performance grade, while the commercial C suffix corresponds to the stated 0°C to 85°C operating-temperature range. A maximum supply voltage of 1.26 V and a nominal 1.2 V FPGA supply are also reported in the available data. The 90 nm Spartan-3 process supports a useful balance of logic capacity, static power, dynamic performance, and manufacturing cost. At up to 630 MHz, the XC3S200-4FT256C can satisfy clock-domain requirements that are more demanding than simple glue logic while remaining smaller and less complex than a high-end FPGA. Exact timing, I/O standards, supported memory interfaces, configuration options, and core-current limits require confirmation in the complete manufacturer datasheet before a new design is released. Typical uses include industrial control and automation, communications equipment, embedded test systems, consumer products, instrumentation, and compact control modules. Its parallel programmable resources can implement multiple finite-state machines, data acquisition logic, communication bridges, and auxiliary processors concurrently. The 256-terminal package also makes the device suitable for designs requiring more configuration and user I/O than a small CPLD, although board density and routing must be assessed at the schematic and PCB stages. Designers should treat the package, voltage rails, decoupling, configuration interface, clocking, and I/O standards as a coordinated system rather than isolated specifications. Place bypass capacitors close to the supply pins, preserve the required configuration path, and verify every ball assignment against the exact package drawing. Because the supplied snippets contain inconsistent secondary descriptions of package and cell data, the authoritative manufacturer pinout and datasheet should control any production implementation. This page combines the verified distributor specifications with engineering-focused application guidance, design notes, parameter comparisons, and same-family drop-in candidates. It also distinguishes confirmed values from unavailable electrical details, helping engineers identify the correct replacement without mistaking a similar FPGA for a guaranteed production substitute.

A field-programmable gate array is a configurable digital semiconductor containing programmable logic blocks, programmable interconnect, and input/output resources. An FPGA belongs to the semiconductor hierarchy, programmable-logic IC hierarchy, and Spartan-3 FPGA family. Unlike a fixed-function application-specific integrated circuit, an FPGA allows system designers to implement parallel logic, control functions, signal processing, and interface logic in hardware and later update the configuration through a configuration memory or JTAG programming path. The XC3S200-4FT256I combines 4,320 logic cells with 200K system gates and a maximum clock frequency of 630 MHz. The -4 speed designation identifies the performance grade, while the I suffix identifies the industrial temperature grade. The device is specified for 0 C to +85 C operation in the supplied distributor data, making it suitable for industrial and embedded control equipment where environmental requirements exceed consumer-grade conditions. The 17 mm by 17 mm FTBGA-256 package supports compact PCB layouts but requires careful escape routing, via-in-pad or via fan-out strategies, assembly-process control, and inspection. The 1.2 V core supply requires a regulated, low-noise supply rail and appropriate power-plane distribution. Because this is a legacy Spartan-3 FPGA, designers should also verify configuration memory availability, toolchain support, lifecycle status, and second-source requirements before committing a new production design. Typical applications include industrial control, instrumentation, data acquisition, communication interfaces, embedded signal processing, and prototype systems requiring configurable parallel logic. The high-pin-count package is particularly useful when the design needs numerous user I/O or dedicated interface resources, although the exact user I/O count is not provided in the verified data. A key design consideration is that replacing an XC3S200-4FT256I is not limited to matching its package. A true drop-in candidate must also preserve pin assignment, voltage requirements, configuration behavior, timing characteristics, and software support. This page summarizes verified distributor and manufacturer-linked information, compares documented drop-in candidates, and identifies engineering details that must be confirmed before PCB release.

Technically, the Spartan-3 fabric uses a four-input lookup table (LUT) per slice logic cell with dedicated fast carry logic for arithmetic chains. The -4 speed grade denotes the fastest standard commercial/industrial timing bin of the Spartan-3 family. Configuration is performed via serial or parallel PROMs (Xilinx Platform Flash) in Master/Slave Serial or SelectMAP modes with JTAG boundary-scan support per IEEE 1149.1. Typical applications include industrial control and motor drive logic, communication protocol bridging, test and measurement instrumentation, and embedded coprocessing with the hardware multipliers for modest DSP tasks. The 17x17mm FTBGA footprint suits space-constrained boards requiring high I/O density. A key design consideration is power: the 1.2V core requires a dedicated regulator, and I/O bank VCCO supplies must match the connected logic standards; total power scales with clock frequency and toggle rates, so use the Xilinx power estimator early in design. This page synthesizes verified distributor data, drop-in family alternatives, and practical design notes not found in the manufacturer datasheet.

A field-programmable gate array is a semiconductor whose digital logic, memory, and I/O paths are configured after manufacture. Within the product hierarchy, the XC3S200-4PQ208C is an FPGA, then a programmable-logic device, and ultimately a semiconductor. Compared with fixed-function logic ICs, an FPGA lets engineers implement parallel processing, control, communications, and signal-generation functions in one reconfigurable device while retaining the same package and pinout across design revisions. The supplied product data identifies 141 I/O, 4,320 logic cells, 480 CLBs, 221,184 RAM bits, and 200,000 system gates. The “-4” speed designation and an associated listing report 630 MHz performance, while the commercial “C” suffix identifies the specified temperature grade. Its 208-pin PQFP package exposes substantially more device I/O than the smaller 100-pin Spartan-3A options, making it suitable for designs with wider external buses or more peripheral connections. The XC3S200-4PQ208C fits industrial control, communications infrastructure, embedded instrumentation, video processing, test equipment, and legacy embedded systems. A practical design can use its programmable logic for parallel data acquisition, protocol conversion, signal conditioning, and supervisory control while retaining configuration data in external nonvolatile flash. Engineers should verify every power rail, configuration interface, and high-speed I/O constraint against the complete Spartan-3 documentation before layout release. Power and termination design remain central to reliable FPGA implementation. Provide the specified core and I/O supplies, route each supply through its documented decoupling network, and use a configuration scheme that matches the board’s flash and control logic. Because the supplied excerpts do not provide full electrical limits, pin assignments, or power-budget data, those details require confirmation from the manufacturer’s official Spartan-3 documentation before schematic completion. This page consolidates verified distributor specifications, same-package family comparisons, commercial availability references, and application-specific engineering guidance. It distinguishes the XC3S200-4PQ208C from smaller Spartan-3 packages and higher-density PQFP208 devices, helping engineers determine whether the device’s logic, memory, I/O, and thermal requirements align with an existing 208-pin PCB design.

Its 200,000-system-gate count describes the family device's logic-equivalent capacity rather than a fixed gate count. The 630 MHz figure likewise requires careful interpretation because achievable system performance depends on the selected design, timing constraints, clocking, I/O standards, routing, and the associated Xilinx toolchain. The 90 nm Spartan-3 architecture supports integration of control logic, data acquisition, communications glue logic, state machines, and modest parallel-processing functions. Reconfigurability allows design revisions to be implemented in the FPGA bitstream rather than through a PCB respin. Dedicated block RAM can buffer sampled or packet data, while programmable I/O can connect the device to external clocks, data buses, transceivers, displays, and industrial interfaces subject to voltage and timing constraints. Typical uses include industrial automation, programmable logic controllers, motor-control and sensor-processing systems, embedded communications, instrumentation, and cost-sensitive consumer or control electronics. The 208-pin PQFP provides more I/O than a small FPGA package, making it useful where parallel external buses, control signals, or multiple interfaces must coexist with the Spartan-3 logic fabric. Design planning should begin with the AMD/Xilinx Spartan-3 datasheet and the appropriate ISE or Vivado-era design flow for the installed device family. Verify the exact pinout, supported I/O standards, configuration requirements, decoupling, clock topology, and exposed thermal and power constraints on the selected package before layout release. This page consolidates verified distributor specifications, pricing references, same-family drop-in candidates, and practical selection considerations for engineers evaluating the XC3S200-4PQ208I.
XC3S200-4TQ144I - 200K Gate Spartan-3 FPGA | AMD | TQFP
The AMD XC3S200-4TQ144I is a Spartan-3 field-programmable gate array with 200,000 system gates, 4,320 logic elements, 221,184 bits of embedded RAM, and 97 I/O pins in a 144-pin TQFP package.

Typical uses include industrial control, embedded communications, instrumentation, data acquisition, display interfaces, and compact embedded processing systems. Its 4,320 logic elements and 221,184 RAM bits make it appropriate for protocol bridging, parallel-to-serial conversion, control-plane logic, and modest algorithmic workloads. Designs requiring substantially greater logic density or memory bandwidth should use a larger FPGA family. Designers should verify the exact pinout, configuration interface, I/O standards, clock requirements, and decoupling recommendations against the manufacturer datasheet before layout release. Because the TQFP package has fine-pitch leads, PCB assembly and inspection require suitable paste, stencil, placement, and inspection processes. Legacy-device supply status and configuration-memory interface compatibility also deserve review before new production commitments. This page consolidates verified distributor specifications, same-family drop-in candidates, practical design guidance, and parameter-level comparisons. It distinguishes confirmed electrical and packaging facts from information that could not be extracted from the supplied web records, helping engineers evaluate the XC3S200-4TQ144I without relying on ambiguous distributor summaries.

The listed electrical characteristics include 63 user I/O pins, a 1.14 V to 1.26 V core-supply range, and a 0 °C to 85 °C operating range. These figures define the principal design constraints for voltage regulation, thermal planning, signal-interface design, and industrial or commercial equipment. Typical uses include industrial control and automation modules, communications-interface adapters, embedded test equipment, and low-to-medium complexity digital systems. The FPGA can implement parallel logic, state machines, counters, protocol front ends, and control functions in one configurable device. Engineers should confirm that the selected design does not require more logic resources, I/O, clocking, or memory than the available device resources provide. The most important design consideration is ensuring that the 1.2 V core rail is generated with adequate tolerance and decoupling, while all connected I/O structures remain compatible with the target board voltage levels. Because this is a surface-mount VQFP package, solderability, pin-1 orientation, assembly profile, and thermal performance should be reviewed against the selected PCB footprint and manufacturing process. This page consolidates distributor availability, verified device parameters, package information, and practical FPGA selection guidance. It also distinguishes exact drop-in alternatives from upgrade candidates so engineers can assess PCB reuse without confusing package compatibility with complete functional equivalence.
XC3S200-4VQ100I - 200K Gate Spartan-3 FPGA | AMD
AMD XC3S200-4VQ100I is a Spartan-3 field-programmable gate array with 200000 system gates, 4320 logic elements, a 1.2 V supply, and a 100-pin TQFP package. The device combines programmable logic, block RAM, and dedicated multiplier resources in a compact 14 mm × 14 mm surface-mount package. Its industrial-oriented ordering suffix supports use in embedded control, communications, instrumentation, and industrial automation systems where deterministic programmable logic is required. A Spartan-3 FPGA is a reconfigurable digital semiconductor in the FPGA and CPLD product hierarchy. Unlike a fixed-function microcontroller or application-specific integrated circuit, an FPGA allows engineers to define parallel logic, state machines, interfaces, and data-processing functions in hardware. Its configurable interconnect routes signals among logic cells, dedicated block RAM, multipliers, and general-purpose I/O, making the device suitable for designs requiring deterministic timing and flexible hardware architecture. The XC3S200-4VQ100I provides 200000 system gates and 4320 logic elements according to distributor listings. The family-level product information also identifies 12 block RAMs, 12 multipliers, and 4 digital clock managers for designs requiring embedded memory, dedicated arithmetic, and clock-management resources. Its 1.2 V core supply and 100-pin TQFP package provide a practical balance between capability, I/O access, and board footprint. The “-4” portion identifies the device speed grade, while “VQ100” identifies the 100-pin package configuration and “I” identifies the industrial temperature grade. These ordering codes allow procurement teams to distinguish devices that otherwise belong to the same Spartan-3 family. Because FPGA designs depend on the configuration file, device speed, pinout, memory resources, and supported I/O standards, engineers should verify the exact ordering code against the AMD/Xilinx datasheet and board constraints before substitution. Typical uses include industrial control logic, low-latency communication interfaces, data acquisition, embedded signal processing, test equipment, and general-purpose embedded systems. The 100-pin package is particularly useful where a larger FPGA would be unnecessary and where external SDRAM or a high-pin-count BGA package would add unnecessary board complexity. Its integrated resources can reduce external logic-component count while retaining software-side reconfiguration flexibility. The primary design consideration is package-level resource and signal-integrity verification. The 100-TQFP footprint requires exact land-pattern, pin-orientation, and power-decoupling review before layout release. Engineers should also account for configuration memory, configuration interface, clocking, I/O voltage limits, unused pins, and startup behavior in the complete FPGA design rather than treating the FPGA only as a collection of logic blocks. This product page consolidates verified distributor specifications, package information, ordering-code details, sourcing links, and engineering guidance. It also distinguishes a genuine same-footprint replacement from a merely similar FPGA family member and records unknown technical values explicitly for engineers to confirm in the manufacturer datasheet.
XC3S200-5FT256C - 200K Gate 1.2V FPGA | AMD | 256-LBGA
The AMD XC3S200-5FT256C is a Spartan-3 field-programmable gate array with 200,000 system gates, 192 logic cells, and a 1.2 V supply in a 256-LBGA package. The -5 speed designation identifies the device performance grade, while the FT256C suffix identifies the lead-free commercial package variant. Its operating temperature range is 0°C to 85°C, making it suitable for cost-sensitive embedded systems that require programmable logic without the resources of a larger FPGA. A field-programmable gate array is a semiconductor whose digital logic and interconnect are configured after manufacture. An FPGA belongs to the broader programmable-logic hierarchy, which includes CPLDs, mask-programmed devices, and application-specific programmable logic. The Spartan-3 architecture combines configurable logic, memory resources, dedicated input/output structures, and programmable interconnect, allowing a designer to implement multiple control, interface, datapath, and signal-processing functions in one device. The XC3S200-5FT256C provides 50,000 system gates according to one distributor listing and 200,000 system gates according to Mouser and Partstack. The verified sources also report 192 logic cells, a 1.2 V FPGA supply, a 256-LBGA package, 256 terminals, and a square package shape. These source differences should be resolved against the applicable AMD Spartan-3 family data sheet before final design release. Because the device belongs to the Spartan-3 generation, engineers should treat it as a legacy programmable-logic platform and validate toolchain availability, configuration method, I/O standards, timing, and sourcing before beginning a new production design. The operating range of 0°C to 85°C distinguishes it from extended-temperature variants. Its 256-ball land-grid-array package also requires a PCB footprint and assembly process capable of handling fine-pitch balls, while configuration storage, clocking, decoupling, and I/O voltage planning remain central implementation concerns. Typical uses include industrial control and factory automation, embedded instrumentation, communications interfaces, display and video control, consumer products, and general-purpose digital signal processing. The Spartan-3 family was specifically positioned for high-volume, cost-sensitive consumer electronic applications, but individual designs still require complete timing, thermal, signal-integrity, and configuration verification. The principal design caution is that a replacement FPGA must match the package, ball assignment, supported I/O standards, voltage requirements, configuration interface, and timing constraints. A device with the same family name or logic density is not automatically pin-compatible. Migration decisions should therefore use AMD pinout data, device-generation constraints, and design-tool checks rather than relying only on distributor similarity labels. This page consolidates the verified distributor and manufacturer references for the XC3S200-5FT256C, distinguishes verified characteristics from parameters requiring confirmation, and provides migration, sourcing, and application guidance that is not present in a basic distributor listing.
XC3S200-5VQ100C - 200K Gate Spartan-3 FPGA | AMD Xilinx
The AMD Xilinx XC3S200-5VQ100C is a Spartan-3 field-programmable gate array with 200,000 system gates, 4,320 logic cells, 63 user I/O pins, and 221,184 RAM bits, supplied in a 100-pin TQFP package. It operates from a 1.2 V supply and is specified for a 0 to 85 °C operating temperature range. A field-programmable gate array is a programmable digital semiconductor that combines configurable logic, programmable interconnect, and memory resources in one device. In the broader semiconductor hierarchy, an FPGA belongs to programmable logic devices and provides a hardware alternative to implementing a fixed function in an application-specific integrated circuit. The Spartan-3 family was designed for cost-sensitive embedded, industrial, consumer, and communication systems. The XC3S200-5VQ100C provides 4,320 logic cells and 221,184 RAM bits for parallel datapaths, control logic, state machines, and interface conditioning. Its 63 user I/O pins provide connections to external memory, sensors, converters, communication transceivers, and display or control peripherals. The -5 speed designation identifies the device's performance grade, while the commercial C temperature designation corresponds to the stated 0 to 85 °C range. The device uses a 1.2 V core supply, making power-supply design important in compact embedded systems. Available details confirm 200,000 system gates, 4,320 logic cells, 63 I/O pins, 221,184 RAM bits, and a 100-TQFP package. Additional detailed information such as exact I/O standards, configuration interface characteristics, and recommended operating limits is not present in the supplied verified records and must be confirmed from the manufacturer datasheet before design release. Typical uses include industrial controllers, embedded control systems, video and image-processing front ends, communication equipment, and consumer electronics. In each case, the Spartan-3 architecture permits logic and memory functions to be updated in the field, reducing the need for a custom ASIC in moderate-volume designs. Designers should preserve the manufacturer's recommended power and decoupling arrangement, validate every I/O voltage and bank configuration, and account for configuration-pin requirements during power-up. Because the supplied records do not include a complete verified pin table, the package drawing is represented by the generic library key rather than an invented pinout. This page combines the verified distributor specifications, packaging information, source links, and drop-in alternatives. It also distinguishes directly comparable speed-grade parts from larger-package or functionally similar devices that cannot replace the target without PCB changes.
