AMD XC3130-3PC68C

Overview

XC3130-3PC68C from Xilinx is a high-performance, 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 - deployed in legacy telecom line cards and industrial control logic replacement.

For engineers reviewing the XC3130-3PC68C datasheet, pinout, applications, or equivalent options, key selection criteria include its 5 V supply compatibility, 68-pin PGA package, soft-start slew-rate limiting at power-up, bitstream compatibility with XC3000A/XC3100A families, and support for serial configuration via XC17XX PROMs.

Technical Context

The XC3130-3PC68C implements a static CMOS FPGA architecture with distributed configuration memory cells controlling IOBs, CLBs, and interconnect resources. Its CLBs provide dual 4-variable LUTs (F/G), programmable flip-flops with shared RD and EC inputs, and flexible clock routing with invertible K inputs.

Interconnect includes general-purpose metal grids (5×5 segments), direct CLB-to-CLB paths (X→B/C, Y→D/A), and horizontal longlines with TBUF access. Configuration is loaded serially or parallel-byte mode, with error-checking of bitstream stop bits and automatic INIT low assertion on failure.

Key Specifications

Pinout & Package

FAQ

What is the operating voltage requirement for XC3130-3PC68C?

The XC3130-3PC68C requires a nominal 5.0 V ± 5% supply voltage and is not compatible with 3.3 V operation. Its I/O buffers are designed for TTL/CMOS threshold compatibility at 5 V, and the internal configuration memory and CLBs are optimized for this rail. Using lower voltages will result in functional failure or undefined behavior.

Does XC3130-3PC68C support in-system reprogramming?

Yes, XC3130-3PC68C supports in-system reprogramming via its serial configuration interface. By asserting PROGRAM low and reloading the bitstream through DIN/CLK, the device can be reconfigured without removal from the board - enabling field updates of logic functionality while maintaining the same 68-pin CPGA footprint.

Is XC3130-3PC68C pin-compatible with XC3030A-3PC68C?

Yes, XC3130-3PC68C is 100% pin-out compatible with XC3030A-3PC68C - both use identical 68-pin CPGA packages and share identical I/O, power, and configuration pin assignments. This allows drop-in replacement in existing PCBs, provided timing and drive requirements are verified.

What configuration memory technology does XC3130-3PC68C use?

XC3130-3PC68C uses static CMOS configuration memory cells - each consisting of two cross-coupled inverters and a pass transistor - providing high noise immunity and resistance to alpha-particle-induced soft errors. Unlike volatile SRAM-based FPGAs, these cells retain configuration indefinitely without refresh, though they require external PROM for power-on loading.

Can XC3130-3PC68C generate its own clock signal?

Yes, XC3130-3PC68C includes an on-chip crystal oscillator amplifier that supports connection to an external quartz crystal or ceramic resonator. When configured, this circuit generates a stable clock signal directly usable by internal CLBs and IOBs - eliminating the need for an external clock generator IC in many timing-critical applications.
