AMD XC3130-4PQ100I

Overview

XC3130-4PQ100I from Xilinx is a high-performance, 2,000-gate Field Programmable Gate Array (FPGA) in a 100-pin PQFP package, featuring a 10×10 Configurable Logic Block (CLB) array, 80 user I/Os, and guaranteed 370 MHz flip-flop toggle rates. It implements synchronous digital logic using static configuration memory, supports TTL/CMOS input thresholds, and integrates on-chip crystal oscillator amplifier for clock generation - used in legacy telecom interface controllers and industrial motion control logic.

For engineers reviewing the XC3130-4PQ100I datasheet, pinout, applications, or equivalent options, this page delivers verified architecture details, CLB-level timing parameters, I/O buffer slew-rate control behavior, Soft Startup initialization sequence, and pin-compatible alternatives for obsolescence-mitigated redesigns.

Technical Context

The XC3130-4PQ100I implements a regular, extendable FPGA architecture with three core configurable elements: a perimeter of programmable Input/Output Blocks (IOBs), a 10×10 core array of Configurable Logic Blocks (CLBs), and hierarchical interconnect resources including horizontal longlines, general-purpose metal grids, and direct CLB-to-CLB paths. Each CLB contains dual flip-flops, five logic inputs (A–E), programmable enable clock (EC), invertible clock (K), and asynchronous reset (RD).

Configuration is loaded via serial or parallel mode into distributed static memory cells; bitstream is compatible with XC3000A, XC3000L, and XC3100A families. The device features Soft Startup - slew-rate limiting all outputs during initial power-up - and error-checking of configuration bitstream stop bits to terminate invalid loads.

Manufacturer

Xilinx, Inc. was a pioneering semiconductor company founded in 1984, specializing in programmable logic devices and later acquired by AMD in 2022. It developed the first commercial FPGA architecture and established industry standards for reconfigurable computing.

The XC3100A family - including XC3130-4PQ100I - was engineered as a performance-optimized extension of the XC3000A series, targeting high-speed digital control, protocol bridging, and real-time signal processing in systems demanding deterministic timing and field-upgradable logic.

FAQ

What is the operating voltage requirement for XC3130-4PQ100I?

The XC3130-4PQ100I requires a nominal 5.0 V ±5% supply on V_CC. It is not compatible with 3.3 V operation - unlike the XC3130L variant. All I/Os are 5 V-tolerant and support TTL/CMOS threshold selection via configuration bits. Power integrity must be maintained with local 0.1 µF ceramic decoupling at each V_CC pin, as specified in the November 1998 XC3000 Series datasheet.

Does XC3130-4PQ100I support in-system reprogramming?

Yes, XC3130-4PQ100I supports in-system reprogramming via its serial configuration interface using CCLK and DIN pins. Configuration can be reloaded without power cycling, enabling field logic updates. The device retains its programmed state only while powered; external PROM (e.g., XC1736) is required for automatic reload at power-up. Soft Startup and bitstream error checking remain active during each reconfiguration cycle.

What is the maximum number of user I/Os available on XC3130-4PQ100I?

XC3130-4PQ100I provides 80 user-configurable I/O pins in its 100-pin PQFP package. All 80 pins support bidirectional operation, programmable input thresholds (TTL or CMOS), optional internal pull-up resistors, and individually selectable slew-rate control. No I/Os are dedicated - every pin except V_CC, GND, RESET, INIT, CCLK, and DIN is fully user-assignable.

How does Soft Startup function on XC3130-4PQ100I?

Soft Startup on XC3130-4PQ100I automatically limits the slew rate of all 80 I/O outputs during the first activation after configuration completes. This prevents simultaneous switching noise (SSN) and ground bounce that could destabilize adjacent circuitry. After startup, individual I/O slew rates revert to values set by configuration bits. The feature is hardware-enforced and requires no user code or external components.

Is XC3130-4PQ100I pin-compatible with other XC3000-series FPGAs?

Yes, XC3130-4PQ100I is 100% pin-out compatible with XC3030A-4PQ100I and XC3030L-4PQ100I in the same PQFP package. It shares identical mechanical footprint, power/ground pin locations, and I/O pin assignments. However, differences in configuration timing, drive strength (8 mA vs. 4 mA), and Soft Startup behavior require verification of timing closure and signal integrity in migrated designs.
