AMD XC3130-4PC68C

Overview

XC3130-4PC68C from Xilinx is a high-performance Field Programmable Gate Array (FPGA) in the XC3100A family, featuring 2,000 maximum logic gates, 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 embedded control and digital signal interface applications.

For engineers reviewing the XC3130-4PC68C datasheet, pinout, applications, or equivalent options, key selection criteria include its 5 V supply compatibility, 68-pin plastic leaded chip carrier (PLCC) package, 190 MHz toggle performance, soft-start slew-rate limiting for ground-bounce mitigation, and bitstream compatibility with XC3000A/XC3000L families.

Technical Context

The XC3130-4PC68C 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, five-input look-up tables, and programmable clock enable (EC), asynchronous reset (RD), and invertible clock (K) inputs.

Configuration is loaded via serial or parallel mode using external PROMs (e.g., XC17XX series); on-chip initialization logic enables automatic power-up loading. IOBs support registered/direct I/O paths, programmable slew rate, 3-state control, and passive pull-up - all configured via static memory bits without runtime reconfiguration overhead.

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 XC3130-4PC68C - was engineered for high-speed, 5 V system integration in industrial and aerospace applications where reliability, deterministic timing, and field-upgradability were essential design requirements.

FAQ

What is the operating voltage range for XC3130-4PC68C?

XC3130-4PC68C operates at a nominal 5 V supply with ±10% tolerance (4.5 V to 5.5 V). This matches standard TTL logic levels and eliminates need for voltage translation when interfacing with legacy microcontrollers or peripheral ICs. The device does not support 3.3 V operation - for low-voltage variants, refer to XC3130L family members.

Does XC3130-4PC68C support in-system reprogramming?

Yes, XC3130-4PC68C supports in-system reprogramming via its serial configuration interface using CCLK and DIN pins. Configuration data can be reloaded dynamically without power cycling, enabling field updates of logic functionality. However, reprogramming halts user logic execution until configuration completes and DONE goes high.

What package type does XC3130-4PC68C use, and is it socket-compatible?

XC3130-4PC68C uses a 68-pin plastic leaded chip carrier (PLCC) package with J-leads. It is fully socket-compatible with standard 68-pin PLCC sockets (e.g., Mill-Max or Sullins), supporting rapid prototyping, functional testing, and field replacement without soldering. Thermal and mechanical specifications align with JEDEC MO-047B.

How does the Soft Startup feature function in XC3130-4PC68C?

Soft Startup in XC3130-4PC68C automatically limits output buffer slew rate during the first activation after configuration completes. This prevents simultaneous switching noise and ground bounce that could corrupt adjacent signals or cause power rail collapse. After startup, individual I/O slew rates revert to values set by configuration bits.

Is XC3130-4PC68C pin-compatible with XC3030A-4PC68?

Yes, XC3130-4PC68C is pin-compatible with XC3030A-4PC68 - both use identical 68-pin PLCC footprints and share the same I/O, power, ground, and configuration pin assignments. This enables drop-in replacement in existing PCBs, provided timing and voltage requirements of the XC3130-4PC68C are met.
