AMD XC3130-4PG84C

Overview

XC3130-4PG84C from Xilinx is a high-performance Field Programmable Gate Array (FPGA) with 2,000 maximum logic gates, 100 Configurable Logic Blocks (CLBs) in a 10×10 array, and 80 user I/Os. It supports system clock speeds over 85 MHz, features TTL/CMOS input thresholds, and integrates complete digital subsystems into a single plastic PGA package for embedded control and interface logic replacement.

For engineers reviewing the XC3130-4PG84C datasheet, pinout, applications, or equivalent options, this device serves as a reprogrammable, bitstream-compatible alternative to TTL/MSI logic and early-generation gate arrays in legacy industrial controllers, test equipment, and communication interface modules.

Technical Context

The XC3130-4PG84C implements a static memory–based FPGA architecture with a perimeter of programmable I/O Blocks (IOBs), a core array of 100 CLBs, and hierarchical interconnect resources including general-purpose metal grids, direct CLB-to-CLB paths, and horizontal longlines. Each CLB contains dual flip-flops, five logic inputs (A–E), programmable clock inversion, and a 32×1 look-up table supporting two independent 4-variable functions or one 5-variable function.

Configuration is loaded via serial or parallel mode into distributed SRAM cells; on-chip initialization logic enables automatic power-up loading from external PROMs (e.g., XC17XX series). The device includes Soft Startup-slew-rate limiting on first output activation-to suppress ground bounce, and supports error-checking of configuration bitstreams during load.

FAQ

What is the maximum system clock frequency supported by XC3130-4PG84C?

XC3130-4PG84C supports system clock speeds over 85 MHz, with guaranteed flip-flop toggle rates up to 370 MHz and logic delays ranging from 1.55 ns to 4.1 ns depending on routing and configuration. This enables reliable operation in real-time control applications requiring sub-12 ns timing closure. The actual achievable clock frequency depends on design complexity and placement, but the device is characterized and tested to meet these specifications under worst-case conditions.

Does XC3130-4PG84C support in-system reprogramming?

Yes, XC3130-4PG84C supports unlimited in-system reprogramming via its serial or parallel configuration interface. The device accepts new bitstreams after power-up without requiring physical removal from the board. Configuration can be initiated by toggling the PROGRAM pin or through software-controlled CCLK sequencing, enabling field updates of logic functionality without hardware modification. XC3130-4PG84C retains full bitstream compatibility with XC3000A and XC3100A families for seamless migration.

What package type and pin count does XC3130-4PG84C use?

XC3130-4PG84C uses an 84-pin Plastic Pin Grid Array (PG84) package with 1.27 mm pitch and 27.94 mm × 27.94 mm body size. It provides 80 user-configurable I/O pins plus dedicated VCC, GND, INIT, PROGRAM, and CCLK pins. The PG84 footprint is mechanically and electrically identical across XC3000A, XC3000L, XC3100A, and XC3100L families, enabling drop-in replacement within the same package variant.

How does the Soft Startup feature work in XC3130-4PG84C?

Soft Startup in XC3130-4PG84C automatically limits the slew rate of all outputs during the first activation after configuration completes. This prevents simultaneous switching noise and ground bounce that could destabilize power rails or corrupt neighboring signals. After startup, individual output slew rates revert to user-programmed settings. XC3130-4PG84C implements this at silicon level-no external components or configuration bits are required to enable it.

Is XC3130-4PG84C pin-compatible with XC3030A-4PG84C?

Yes, XC3130-4PG84C is 100% pin-out compatible with XC3030A-4PG84C and other members of the XC3000/XC3100 families in the PG84 package. All I/O, power, ground, and configuration pins occupy identical locations. However, XC3130-4PG84C includes additional internal features-including Soft Startup and configuration bitstream error checking-that are not present in XC3030A-4PG84C. No PCB changes are required for substitution.
