AMD XC3130-4PC84C

Overview

XC3130-4PC84C from Xilinx is a high-performance, 2,000-gate Field Programmable Gate Array (FPGA) in the XC3100A family, featuring a 10 × 10 Configurable Logic Block (CLB) array, 80 user I/Os, and guaranteed 190 MHz flip-flop toggle rate with 1.55 ns logic delay. It operates at 5 V, supports TTL/CMOS input thresholds, and integrates on-chip crystal oscillator amplifier for clock generation in digital subsystems such as protocol bridges and industrial control logic.

For engineers reviewing the XC3130-4PC84C datasheet, pinout, applications, or equivalent options, key selection criteria include its 5 V supply compatibility, 84-pin plastic leaded chip carrier (PLCC) package, soft-start slew-rate limiting at power-up, bitstream compatibility with XC3000A/XC3100A families, and support for serial configuration via XC17XX PROMs.

Technical Context

The XC3130-4PC84C implements a static memory-based FPGA architecture with distributed configuration memory cells controlling IOBs, CLBs, and interconnect resources. Its CLBs contain dual flip-flops, five-input look-up tables, programmable clock polarity, and asynchronous reset-enabling synchronous logic design with sub-2 ns timing closure.

Interconnect includes general-purpose metal grids, direct CLB-to-CLB paths (e.g., X→B/C, Y→D/A), and horizontal longlines with TBUF access. Configuration is loaded serially or byte-parallel from external PROMs, with error-checking of bitstream stop bits and automatic INIT assertion on failure.

Key Specifications

Pinout & Package

XC3130-4PC84C uses an 84-pin Plastic Leaded Chip Carrier (PLCC) package with J-lead configuration, 25.4 mm × 25.4 mm body size, and 1.27 mm pitch. Pin numbering follows standard PLCC clockwise sequence starting from the index corner.

Manufacturer

Xilinx, founded in 1984, pioneered commercial FPGA technology and developed the XC3000 series as the industry's first widely adopted field-programmable logic platform.

The XC3100A family-including XC3130-4PC84C-was engineered to deliver ultra-high-speed digital logic integration for 1990s-era embedded systems requiring >85 MHz clock rates and deterministic timing without ASIC NRE costs.

FAQ

What is the maximum guaranteed operating frequency of the XC3130-4PC84C?

The XC3130-4PC84C guarantees a 190 MHz flip-flop toggle rate and supports system clock speeds exceeding 85 MHz. This is achieved through its advanced CMOS process and optimized interconnect architecture. The 1.55 ns logic delay enables tight timing closure in synchronous designs. Actual achievable frequency depends on design complexity, routing, and I/O loading-but the device's characterization ensures these minimums across temperature and voltage corners.

Does the XC3130-4PC84C support 3.3 V operation?

No, the XC3130-4PC84C is a 5 V-only device and is not rated for 3.3 V operation. It belongs to the XC3100A family, which requires VCC = 5 V ± 10%. For 3.3 V applications, Xilinx offered the pin-compatible XC3130L variant-but XC3130-4PC84C itself must be powered at 5 V. Applying 3.3 V will result in undefined behavior and failure to configure or operate correctly.

Can the XC3130-4PC84C be reconfigured in-system?

Yes, the XC3130-4PC84C supports in-system reconfiguration via its CCLK and DIN pins using serial mode. Configuration data can be loaded from an XC17XX serial PROM or a microcontroller-driven interface. The device retains its programmed logic until power loss or explicit reconfiguration. Soft Startup and bitstream error checking remain active during each reload, ensuring robust field updates without hardware reset cycles.

What development tools were originally used for the XC3130-4PC84C?

The XC3130-4PC84C was designed using Xilinx Foundation Series software, which included schematic capture, automatic place-and-route, logic/timing simulation, and bitstream generation. It also interfaced with third-party tools from Viewlogic, Cadence, and Mentor Graphics. Modern synthesis is possible via open-source tools like xc3sprog and Project Trellis-but official support ended with Xilinx WebPACK 6.x, and no native Vivado support exists.

Is the XC3130-4PC84C still in production?

No, the XC3130-4PC84C is obsolete and no longer manufactured by Xilinx. It was discontinued in the early 2000s following the introduction of Spartan and Virtex families. However, Aetrix Electronics maintains traceable, tested inventory sourced from authorized legacy channels, with full documentation and configuration PROM compatibility assurance for ongoing maintenance and repair of legacy systems.
