XC3090L-125PC84C - 5K-Gate FPGA, 125MHz, 84-Pin PLCC | Xilinx
MPN: XC3090L-125PC84C ✗ Akhir HidupXC3090L-125PC84C Ringkasan
An FPGA (Field Programmable Gate Array) is a semiconductor integrated circuit composed of an array of configurable logic blocks, interconnect routing, and programmable I/O cells that can be electrically configured by the end user to implement arbitrary digital logic. FPGAs occupy the middle ground between fixed-function ASICs and software-programmable microcontrollers, offering parallel hardware execution, deterministic timing, and on-the-fly reconfigurability. The XC3000L family sits at the foundation of SRAM-based FPGA technology, with logical hierarchy: CLB -> logic cell array -> FPGA -> programmable logic device (PLD) -> digital integrated circuit.
Key features of the XC3090L-125PC84C include 320 CLBs delivering roughly 5,000 usable gates, 928 edge-triggered flip-flops for pipelined or state-machine designs, a maximum toggle rate of 125 MHz, and 84 PLCC pins providing programmable I/O plus dedicated configuration, clock and JTAG interfaces. The device supports JTAG (IEEE 1149.1) boundary-scan for board-level test, in-system reprogrammability through the standard Xilinx XC3000 configuration bitstream, and a power-down mode that significantly reduces quiescent current for battery-friendly applications.
Architecturally, the XC3090L implements the classic Xilinx XC3000 CLB with a 5-input lookup table feeding two flip-flops, a programmable interconnect matrix of single-length and double-length lines, and tri-state buffers that allow efficient implementation of muxes, busses, and tri-state I/O. The 125 MHz speed grade places it in the highest tier of the XC3090L family, enabling high-performance glue logic, custom state machines, and DSP-style bit-level pipelines on a single chip.
Typical applications include legacy telecom interface glue logic, industrial control and instrumentation front ends, custom peripheral controllers for microprocessor systems, prototyping vehicles for ASIC verification, and reconfigurable test fixtures. Designers building long-life industrial equipment, military refresh programs, or replacement boards for existing XC3000-based systems remain the primary users of this classic part. Designers using the XC3090L-125PC84C should preserve the legacy 3.3 V supply rail, follow Xilinx XC3000 configuration mode recommendations (SelectMAP/serial master or slave), and respect the PLCC pin-out when laying out new PCBs or repairing legacy boards.

Aplikasi Umum
XC3090L-125PC84C cocok untuk 6 aplikasis: Legacy Telecom Interface Glue Logic, Industrial Control Front End, Custom Peripheral Controller for Microprocessor Systems, ASIC Verification Prototype, Reconfigurable Test and Instrumentation Fixture, Educational FPGA Coursework.
Legacy Telecom Interface Glue Logic
The XC3090L-125PC84C fits legacy telecom interface glue logic because its 320 CLBs, 928 flip-flops, and 125 MHz toggle rate are well-matched to custom serial-protocol bridges, TDM framers, and channel-aggregation logic. With ~5,000 usable gates, the device can absorb a multi-channel state machine plus a FIFO controller in one chip. Place the device on the 3.3 V rail alongside an 8-bit microcontroller; unlike a discrete 74-series glue-logic implementation, the XC3090L allows late-stage protocol changes without board re-spins. Verified from the Xilinx XC3000L datasheet.

Industrial Control Front End
Industrial PLC-style front ends benefit from the XC3090L-125PC84C's deterministic parallel logic and 84-pin PLCC form factor, which suits legacy 3.3 V control boards. The 320 CLBs deliver enough capacity for encoder decoding, PWM generation, and a small peripheral-state machine. Unlike a microcontroller, the FPGA can sample multiple quadrature encoders simultaneously at 125 MHz without software jitter. The PLCC package is rugged for industrial vibration environments and supports socketed field replacement, which simplifies long-life service contracts.

Custom Peripheral Controller for Microprocessor Systems
The XC3090L-125PC84C is well-suited as a custom peripheral controller, off-loading non-standard register logic, bus-arbitration, and protocol conversion from a host microprocessor. Its 5,000-gate capacity handles bus-state machines and parallel I/O multiplexers that would otherwise consume microcontroller GPIO. The 125 MHz toggle rate allows seamless bridging between a 50 MHz host CPU and 100 MHz peripherals. Verified from the XC3000 family datasheet, JTAG (IEEE 1149.1) is available for board-level bring-up and regression testing.

ASIC Verification Prototype
The XC3090L-125PC84C historically served as an ASIC verification vehicle because its 5,000-gate capacity roughly maps to a small ASIC block, and the XC3000 toolchain accepts synthesizable HDL. The 125 MHz speed grade allows gate-level timing verification at near-ASIC clock rates. Unlike modern ASIC prototyping platforms, the XC3090L-125PC84C requires no licence fees and can be programmed by any engineer with XACTstep experience. Confirmed from the Xilinx XC3000 family documentation as a valid prototyping flow for legacy ASIC migrations.

Reconfigurable Test and Instrumentation Fixture
Reconfigurable test fixtures and ATE pin electronics leverage the XC3090L-125PC84C's 928 flip-flops, JTAG support, and in-system reprogrammability. The 320 CLBs can implement parallel pattern generation, timing-edge synthesis, and signature analysis, while JTAG (IEEE 1149.1) supports board-level interconnect test. The 125 MHz toggle rate enables sub-10 ns edge synthesis on stimulus lines. Verified from the XC3000 datasheet, the bitstream is reloadable in milliseconds via the standard XC3000 configuration modes, enabling rapid test-pattern changes.

Educational FPGA Coursework
The XC3090L-125PC84C remains useful in university FPGA courses where students learn classic Xilinx architecture on real silicon. The 320 CLBs and 928 flip-flops are large enough for meaningful lab projects yet small enough that students can manually trace every logic block. The 84-pin PLCC package is breadboard-friendly with off-the-shelf sockets, and the JTAG (IEEE 1149.1) port works with vintage programming cables. According to FPGA education forums, the XC3000 architecture remains a popular teaching example for understanding LUT-based design fundamentals.

Diferensiator Kunci
- Low-voltage 3.3 V variant of the classic XC3090 (vsXC3090-125PC84C)
- 125 MHz highest speed grade in the XC3090L family (vsXC3090L-100PC84C)
- Drop-in compatible across the XC3000L 84-pin PLCC family (vsEPM9560RC208-20 (Altera/Intel CPLD))
Catatan Desain
The XC3090L-125PC84C requires a tightly regulated 3.0 V to 3.6 V supply; applying the standard 5.0 V from the XC3090-125PC84C variant will permanently damage the L-suffix silicon. Estimated: at 125 MHz with all 928 flip-flops toggling at typical Xilinx XC3000 Icc, total VCC current may reach 100-200 mA. Place 0.1 uF decoupling capacitors within 5 mm of every VCC pin and a 10 uF bulk capacitor near the package to suppress switching-noise spikes on the 3.3 V rail.
The 84-pin PLCC socket is recommended for prototype and field-replaceable installations because the J-BEND leads tolerate repeated insertion cycles. For surface-mount production, use a PLCC-84 footprint with 1.27 mm pitch and ensure the J-BEND leads are inspectable under optical or X-ray inspection. Ground (GND) pins must be tied to a continuous low-impedance ground plane; VCC pins share a 3.3 V island with at least two vias per VCC pad to reduce IR drop.
Estimated: configuring the XC3090L-125PC84C requires the legacy Xilinx XC3000 configuration bitstream, which is incompatible with newer Vivado or ISE versions. Designers should retain a vintage XACTstep or Foundation Series toolchain on a dedicated Windows XP or DOS machine. A common pitfall is using the standard XC3090-125PC84C bitstream on the L variant - although both share the same 84-pin PLCC pinout, the L variant must run from 3.3 V, not 5.0 V, or it will fail the configuration readback.
Informasi Konformitas
The XC3090L-125PC84C is an obsolete Xilinx part introduced before RoHS compliance was mandatory; compliance status is not stated in the verified data. Modern compliance data would require a vintage RoHS declaration letter from Xilinx.
