XC3090LTM-8PC84C - XC3000L FPGA, 6K Gates, 84-PLCC | Xilinx
MPN: XC3090LTM-8PC84C ✗ Cuối đờiXC3090LTM-8PC84C Tóm tắt
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.

Ứng dụng tiêu biểu
XC3090LTM-8PC84C phù hợp cho 6 Áp dụngs: Legacy 3.3V Digital Glue Logic, Prototype ASIC Emulation, Custom Microcontroller Peripheral Interfacing, Industrial Control Subsystem Logic, Legacy Bus Arbitration and Interface Bridging, Low-Volume Production Replacement for EOL ASICs.
Legacy 3.3V Digital Glue Logic
The XC3090LTM-8PC84C fits legacy 3.3V glue-logic applications because the XC3000L 'L' suffix explicitly designates a 3.0V-3.6V core operating range, eliminating the need for 5V-to-3.3V level shifting on every inter-board signal. Its ~6,000 usable gates and 320 CLBs are sufficient to implement address decoding, wait-state generation, custom interrupt controllers, and parallel-bus arbiters that were historically built from 74-series TTL. The 84-PLCC package supports socket-based prototyping, allowing the FPGA to be reprogrammed multiple times during bring-up without reworking the PCB - a key advantage for legacy repair scenarios where documentation may be incomplete.
Được đề xuất
Prototype ASIC Emulation
The XC3090LTM-8PC84C is well-suited to prototype ASIC emulation in low-volume 3.3V designs because the same XC3000L bitstream can be reloaded to iterate logic revisions in minutes, whereas a mask-programmed ASIC requires weeks of fab turnaround. With ~320 CLBs and ~6,000 gates, the device emulates moderate-complexity ASICs such as custom peripheral controllers, DSP front-ends, and serial-protocol engines. The 84-PLCC package is compatible with standard IC sockets, making it ideal for breadboard and evaluation-board emulation where the FPGA may be swapped between design iterations. Engineers can validate functionality, timing, and I/O behavior before committing to mask tooling.
Được đề xuất
Custom Microcontroller Peripheral Interfacing
The XC3090LTM-8PC84C fits custom microcontroller-peripheral interfacing because its ~320 CLBs and 64 configuration-memory bits per CLB deliver enough logic to implement complex state machines, FIFO buffers, and protocol converters between microcontrollers and legacy peripherals. The 3.3V core aligns with modern 3.3V MCUs (ARM7, MSP430, lower-end Cortex-M), eliminating the level-translator circuitry that older 5V FPGAs would require. The 84-PLCC footprint exposes ~64 user I/O pins, sufficient for 8- or 16-bit parallel buses plus handshake and interrupt signals. Engineers building glue-logic adapters between an MCU and legacy parallel or serial peripherals rely on the XC3090L family for its deterministic, hardware-parallel timing.
Được đề xuất
Industrial Control Subsystem Logic
The XC3090LTM-8PC84C fits industrial control subsystem logic because its 3.3V low-voltage operation reduces power dissipation relative to the 5V XC3000 series, an important factor in enclosed industrial cabinets where thermal management is constrained. The XC3090L density (~6,000 gates, 320 CLBs) is sufficient for PLC scan engines, custom motor-control state machines, and encoder-interface logic. The TM suffix indicates a specific speed/temperature combination suitable for industrial environments. The 84-PLCC package is mechanically rugged and socket-compatible for field-replaceable modules, simplifying maintenance in factory-automation installations.
Được đề xuất
Legacy Bus Arbitration and Interface Bridging
The XC3090LTM-8PC84C fits legacy bus-arbitration and interface-bridging applications because its ~6,000-gate capacity is well-matched to multi-master bus controllers, DMA engines, and protocol-converter bridges (e.g., ISA-to-local bus, VME-to-PCI in legacy telecom). The 3.3V core is compatible with 3.3V bus standards while the I/O structure can interface to 5V devices with proper bus-hold or pull-up design. The 84-PLCC footprint is shared with many legacy bus-controller ASICs of the same era, simplifying PCB redesign when migrating from a discontinued ASIC to a soft-logic implementation. Engineers value the deterministic timing of the XC3000L architecture for arbitration circuits.
Được đề xuất
Low-Volume Production Replacement for EOL ASICs
The XC3090LTM-8PC84C is frequently deployed as a low-volume production replacement for end-of-life ASICs because its XC3000L bitstream format is well-documented and its 84-PLCC footprint matches several legacy ASICs from the early 1990s. Designers can reproduce the functionality of a discontinued custom ASIC by porting its gate-level netlist to an XC3000L bitstream, extending the service life of installed equipment (medical instruments, industrial controllers, telecom gear) without requiring PCB redesign. The PLCC socket allows swap-in replacement during field service. This use case dominates the current demand for the XC3090LTM-8PC84C and explains its continued availability on the secondary market despite obsolete status.

- Same-family bitstream format preserves configuration PROM compatibility (vsXC3090A-7PC84C)
Ghi chú thiết kế
Estimated: do not attempt to program the XC3090LTM-8PC84C with modern Vivado, WebPACK, or ISE toolchains - these tools do not support the XC3000L family. Configuration bitstream generation requires the legacy XACT or Foundation software, which is EOL and may require a Windows XP or Windows 2000 virtual machine. Engineers maintaining legacy systems must verify that the original configuration PROM image is preserved before the toolchain environment is decommissioned.
Estimated: at a typical 3.3 V VCC and ~30 mA quiescent current, the XC3090LTM-8PC84C dissipates roughly 0.1 W static power. Under switching conditions with all 64 I/O pins toggling at moderate rates, power can rise to ~0.5 W. Decoupling requires at least one 0.1 uF ceramic capacitor per VCC pin (4 VCC pins on the 84-PLCC) plus a single 10 uF bulk tantalum near the package. Unlike modern FPGAs, the XC3000L family does not require high-frequency decoupling for the internal logic - the 0.1 uF caps primarily support I/O switching transients.
The 84-PLCC package is suitable for both surface-mount and socket-based prototyping. For production boards, use a standard surface-mount PLCC land pattern with J-lead footprint per JEDEC MS-018. For development, use a 84-pin PLCC socket (e.g., 3M Textool or Aries 84-PLCC) - this allows the FPGA to be reprogrammed and swapped without desoldering. Note that the PLCC's J-lead termination is more mechanically robust than fine-pitch QFP leads, but the package is taller than TQFP alternatives.
Estimated: at 0.5 W worst-case power dissipation and a typical PLCC theta_JA of ~50 C/W, the XC3090LTM-8PC84C junction temperature rises ~25 C above ambient at 25 C room temperature - well within the 125 C commercial limit. No heatsink is required. However, in enclosed industrial cabinets with ambient temperatures approaching 70 C, verify that the dissipation stays below 1 W to maintain margin. The PLCC package's plastic body limits maximum ambient to 70 C for reliable operation in commercial grade.
Thông tin tuân thủ
Compliance status is unknown because the XC3000L family was released before widespread RoHS/REACH adoption and the part is obsolete. The PC84 PLCC package was originally lead-bearing; later production runs may have transitioned but were not formally re-certified. AEC-Q100 is not applicable to legacy FPGAs of this era.
