AMD XC3130-4PG84I

Overview

XC3130-4PG84I from Xilinx is a high-performance, 2,000-gate Field Programmable Gate Array (FPGA) in a 84-pin plastic PGA package, featuring 10×10 CLB array (100 CLBs), 80 user I/Os, and guaranteed 190 MHz flip-flop toggle rate with 1.55 ns logic delay. It implements custom digital logic via static configuration memory, supports TTL/CMOS input thresholds, and integrates configurable I/O blocks, logic blocks, and programmable interconnect for subsystem-level integration.

For engineers reviewing the XC3130-4PG84I datasheet, pinout, applications, or equivalent options, key selection criteria include its 3.3 V nominal supply voltage (XC3100L family), soft-start slew-rate limiting at power-up, error-checked configuration bitstream loading, and compatibility with XC3000A/XC3000L bitstreams and footprints.

Technical Context

The XC3130-4PG84I implements a regular, extendable FPGA architecture comprising a perimeter of programmable I/O Blocks (IOBs), a core 10×10 array of Configurable Logic Blocks (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 LUT supporting two 4-variable functions or one 5-variable function.

Configuration is stored in distributed static memory cells loaded at power-up from external serial PROM (e.g., XC17XX series) or parallel memory; bitstream integrity is verified during load via stop-bit checking, and outputs are slew-rate limited during initial startup to suppress ground bounce. IOBs support registered/direct I/O, programmable pull-up, TTL/CMOS threshold selection, and 8 mA sink/source drive capability.

Manufacturer

Xilinx, Inc. is a pioneering semiconductor company founded in 1984, specializing in programmable logic devices and now part of AMD. It introduced the first commercial FPGA and defined the modern reconfigurable computing architecture.

The XC3100L family-including XC3130-4PG84I-was designed for high-reliability, low-voltage (3.3 V) digital logic replacement in industrial, medical, and test equipment where power efficiency, configuration integrity, and long-term availability are critical.

FAQ

What is the operating voltage range for XC3130-4PG84I?

The XC3130-4PG84I operates at a nominal supply voltage of 3.3 V, with a specified range of 3.0 V to 3.6 V. This low-voltage operation reduces active and quiescent power consumption compared to 5 V XC3100A variants, making it suitable for battery-powered and thermally constrained applications. The device maintains full functionality-including 190 MHz toggle rate and 1.55 ns logic delay-across this range, and all I/Os support TTL or CMOS threshold selection independent of VCC level.

Does XC3130-4PG84I support in-system reprogramming?

Yes, XC3130-4PG84I supports in-system reprogramming via its standard configuration interface. The device can be reconfigured dynamically by asserting the PROGRAM pin, allowing logic changes without power cycling. Configuration data is loaded serially (e.g., from XC17XX PROM) or in byte-parallel mode, and the built-in error-checking circuitry validates stop bits during each load. This enables field-upgradable functionality in deployed systems such as test equipment or industrial controllers where XC3130-4PG84I serves as the core logic engine.

Is XC3130-4PG84I pin-compatible with other XC3000-series FPGAs?

Yes, XC3130-4PG84I is 100% pin-out compatible with XC3030A-4PG84C and XC3030L-4PG84C within the same 84-pin PGA package. All share identical mechanical footprint, power/ground pin locations, and I/O pin assignments. However, XC3130-4PG84I requires 3.3 V supply and includes additional internal features (soft-start, bitstream error checking) not present in earlier XC3000A/L parts-so board-level voltage regulation and reset timing must be verified for drop-in replacement.

What development tools support XC3130-4PG84I design entry and simulation?

XC3130-4PG84I is supported by Xilinx Foundation Series and M1 software suites (circa 1998), which provide schematic capture, automatic place-and-route, logic/timing simulation, and interactive design optimization. These tools generate bitstreams compatible with XC3130-4PG84I's configuration memory and support interfaces to third-party environments including Viewlogic, Cadence, and Mentor Graphics. The XC3130-4PG84I's architecture allows use of the same design flow and netlist models as XC3000A/L devices, ensuring backward compatibility for existing projects.

How does the Soft Startup feature of XC3130-4PG84I improve system reliability?

The Soft Startup feature in XC3130-4PG84I automatically limits the slew rate of all outputs during the first activation after configuration, preventing simultaneous switching noise and ground bounce that could disrupt adjacent analog circuits or cause false triggering in digital receivers. This is especially valuable in mixed-signal systems like medical imaging front-ends where XC3130-4PG84I formats sensor data. After startup, individual I/O slew rates revert to user-configured settings, maintaining full timing control for normal operation.
