AMD XC3130-5PC84C

Overview

XC3130-5PC84C from Xilinx is a 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 XC3130-5PC84C datasheet, pinout, applications, or equivalent options, key selection criteria include its 5 V supply compatibility, 84-pin plastic leaded chip carrier (PLCC) package, bitstream compatibility with XC3000A/XC3000L families, and Soft Startup slew-rate limiting for ground-bounce mitigation during power-up.

Technical Context

The XC3130-5PC84C implements a static memory-based FPGA architecture with distributed configuration memory cells controlling CLBs, IOBs, and interconnect resources. Its CLBs provide dual 4-variable LUTs plus two flip-flops per block, programmable clock polarity, and asynchronous reset; IOBs support registered/direct I/O paths, programmable 3-state control, and TTL/CMOS threshold selection.

Configuration is loaded via byte-parallel or serial mode using external PROMs (e.g., XC17XX series), with automatic error checking of bitstream stop bits and INIT pin assertion on failure. The device uses an advanced CMOS process enabling higher speed than XC3000A while maintaining full pin-out and software compatibility.

The XC3100A family-including XC3130-5PC84C-was designed to deliver enhanced speed and reliability over the XC3000A line while maintaining full software and footprint compatibility for upgrade paths in telecom, industrial, and defense systems.

FAQ

What is the maximum operating frequency of the XC3130-5PC84C?

The XC3130-5PC84C guarantees a 190 MHz flip-flop toggle rate and supports system clock speeds over 85 MHz. Its 1.55 ns logic delay enables robust timing closure for synchronous designs targeting up to 64 MHz clock domains without pipelining. Actual achievable frequency depends on routing density and logic depth per path, but the device's architecture ensures consistent performance across temperature and voltage ranges specified in the 1998 datasheet.

Does the XC3130-5PC84C support in-system reprogramming?

Yes, the XC3130-5PC84C supports unlimited in-system reprogramming via its PROGRAM pin and serial/parallel configuration interface. Configuration data is loaded into volatile static RAM cells, allowing field updates without device removal. The INIT pin provides real-time feedback on configuration success, and Soft Startup ensures safe output behavior after each reload. This capability is fully supported by Xilinx Foundation and Alliance development tools.

What package type does the XC3130-5PC84C use, and is it RoHS compliant?

The XC3130-5PC84C uses an 84-pin Plastic Leaded Chip Carrier (PLCC) package with J-leads and 1.27 mm pitch. As a 1998-era device, it predates RoHS legislation and contains lead in both die attach and solder plating. Aetrix Electronics supplies only original Xilinx-marked units meeting the specification in the November 1998 datasheet; lead-free alternatives are not available for this part number.

Can the XC3130-5PC84C replace an XC3030A-5PC84C on the same PCB?

Yes, the XC3130-5PC84C is pin-out and footprint compatible with the XC3030A-5PC84C and requires no PCB changes. It accepts identical configuration bitstreams and operates at the same 5 V supply. However, due to its higher speed grade and added features (Soft Startup, configuration error checking), firmware and timing constraints may require validation-but no hardware modification is needed for drop-in replacement.

Is there an on-chip oscillator in the XC3130-5PC84C?

Yes, the XC3130-5PC84C includes an on-chip crystal oscillator amplifier that supports external quartz crystals from 1 MHz to 20 MHz. When connected between OSC1 and OSC2 pins (P33 and P34), it generates a stable clock signal directly usable by CLB and IOB logic without external oscillator components. This feature reduces BOM count and improves system-level EMI performance compared to discrete clock sources.
