AMD XC3130-5PC68C

Overview

XC3130-5PC68C 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 industrial control interfaces and protocol bridging logic.

For engineers reviewing the XC3130-5PC68C datasheet, pinout, applications, or equivalent options, key selection criteria include its 5 V supply compatibility, 8 mA output drive capability, soft-start slew-rate limiting during power-up, configuration bitstream error checking, and architectural compatibility with XC3000A/XC3100A bitstreams.

Technical Context

The XC3130-5PC68C implements a static CMOS FPGA architecture with distributed configuration memory cells controlling programmable I/O Blocks (IOBs), Configurable Logic Blocks (CLBs), and interconnect resources. Its CLBs contain dual flip-flops with shared asynchronous reset (RD), invertible clock (K), and enable clock (EC), supporting both registered and direct I/O paths.

Configuration is loaded via serial or parallel modes using external PROMs (e.g., XC17XX series); the device performs bitstream format validation during load and enforces soft startup-slew-rate limiting all outputs on initial power-up to suppress ground bounce. It uses a 32×1 look-up table per CLB for combinatorial logic and supports FGM mode for functions up to seven variables.

Key Specifications

Pinout & Package

XC3130-5PC68C is packaged in a 68-pin plastic leaded chip carrier (PLCC), with leads arranged in a square J-lead configuration. The package provides full access to all 80 user I/Os, 4 dedicated power/ground pins (VCC, GND), and essential configuration/control signals including INIT, PROGRAM, CCLK, DIN, and DONE.

Manufacturer

Xilinx, founded in 1984, pioneered commercial FPGA technology and established foundational architectures for reconfigurable logic design before its acquisition by AMD in 2022.

The XC3100A family-including XC3130-5PC68C-was engineered to deliver ultra-high-speed programmable logic for demanding digital subsystems in telecommunications infrastructure, industrial automation, and instrumentation, extending the XC3000A architecture with enhanced interconnect and process-derived performance gains.

FAQ

What is the maximum guaranteed toggle rate for XC3130-5PC68C?

The XC3130-5PC68C has a guaranteed minimum flip-flop toggle rate of 190 MHz, verified under worst-case conditions (5 V ±5%, 70 °C junction temperature). This specification enables reliable operation in systems requiring clock frequencies above 85 MHz and ensures timing predictability for synchronous logic blocks implemented in the device. The 190 MHz rating applies to internal CLB flip-flops and is documented in the November 1998 XC3000 Series datasheet revision 3.1.

Does XC3130-5PC68C support 3.3 V operation?

No, XC3130-5PC68C is a 5 V-only device and does not support 3.3 V operation. It belongs to the XC3100A family, which requires nominal 5.0 V ±5% supply. For 3.3 V operation, Xilinx offers the pin-compatible XC3130L variant (e.g., XC3130L-5PC68C), which shares the same logic capacity and package but uses a low-voltage CMOS process. Using XC3130-5PC68C with 3.3 V will result in functional failure and is outside absolute maximum ratings.

How many configuration bits does XC3130-5PC68C require?

XC3130-5PC68C requires 22,176 configuration bits to fully define its logic functionality, interconnect routing, and I/O settings. This value is fixed for the 10×10 CLB array size and matches other members of the XC3030A/XC3130A family. Configuration data is loaded serially (e.g., via XC1701 PROM) or in byte-parallel mode, and the device validates bitstream framing during load to ensure integrity before entering user mode.

Is XC3130-5PC68C pin-compatible with XC3030A-5PC68C?

Yes, XC3130-5PC68C is 100% pin-out compatible with XC3030A-5PC68C and other XC3000-series devices in the 68-pin PLCC package. All user I/Os, power, ground, and configuration pins occupy identical physical locations. However, XC3130-5PC68C adds internal features-including soft startup and bitstream error checking-that are inactive in XC3030A-5PC68C. No PCB changes are needed when upgrading from XC3030A-5PC68C to XC3130-5PC68C.

What development tools were originally used to program XC3130-5PC68C?

XC3130-5PC68C was designed for use with Xilinx Foundation Series software (v1.x–v2.x) and earlier XACT tools, supporting schematic capture, automatic place-and-route, logic/timing simulation, and bitstream generation. It interfaces with industry-standard environments including Viewlogic, Cadence, and Mentor Graphics. Configuration PROMs such as XC1701, XC17128, or XC1764 were used for serial loading; parallel programming required byte-wide PROMs or host processor control via the CCLK/DIN interface.
