AMD XC2S30-5VQ100C

Overview

XC2S30-5VQ100C from AMD (formerly Xilinx) is a Spartan-II family FPGA with 30,000 system gates, 176 logic cells, and 100-pin VQFP packaging. It operates at 5 ns input/output delay and supports 3.3 V I/O with 2.5 V core voltage. It is used in industrial control logic and low-cost communication interface bridging.

For engineers reviewing the XC2S30-5VQ100C datasheet, pinout, applications, or equivalent options, key selection criteria include I/O count, logic cell density, VQFP thermal performance, and compatibility with Xilinx Foundation/ISE design tools.

Technical Context

The XC2S30-5VQ100C implements configurable logic blocks (CLBs), distributed RAM, and dedicated carry logic for arithmetic functions. It supports IEEE 1149.1 JTAG boundary-scan testing and includes global clock routing with four dedicated clock inputs.

Configuration is performed via serial PROM or parallel slave mode using SelectMAP interface. The device requires external configuration memory and does not include on-chip non-volatile configuration storage.

FAQ

What is the core voltage requirement for XC2S30-5VQ100C?

The XC2S30-5VQ100C requires a regulated 2.5 V ± 3% core supply for internal logic operation. This is independent of the 3.3 V I/O supply rails. Proper decoupling with 100 nF ceramic capacitors near each VCCINT pin is mandatory to maintain signal integrity and avoid configuration failure during power-up sequences. The XC2S30-5VQ100C will not function correctly if VCCINT deviates beyond specification.

Does XC2S30-5VQ100C support in-system programming?

Yes, XC2S30-5VQ100C supports in-system programming via its IEEE 1149.1 JTAG interface (TCK/TMS/TDI/TDO pins). It can be programmed or reconfigured while mounted on the target board using standard JTAG adapters and Xilinx IMPACT software. The XC2S30-5VQ100C does not retain configuration after power loss and relies on external PROM or processor-controlled reconfiguration.

What configuration modes are supported by XC2S30-5VQ100C?

The XC2S30-5VQ100C supports Master Serial, Slave Serial, and SelectMAP parallel configuration modes. Master Serial uses an external PROM; Slave Serial allows configuration by a host processor; SelectMAP enables high-speed parallel loading. All modes require proper initialization of PROGRAM_B and monitoring of DONE pin. The XC2S30-5VQ100C does not support internal configuration memory.

Is XC2S30-5VQ100C pin-compatible with other Spartan-II VQFP-100 devices?

XC2S30-5VQ100C is pin-compatible with XC2S15-5VQ100C and XC2S50-5VQ100C within the same speed grade and package variant. Power and ground pin locations, global clock inputs, JTAG, and configuration pins are identical. I/O pin assignments match across these variants, enabling hardware reuse when upgrading logic density without PCB revision.

What I/O standards are supported by XC2S30-5VQ100C?

XC2S30-5VQ100C supports LVTTL, LVCMOS, PCI, and SSTL-2 I/O standards through its SelectI/O technology. Each I/O bank has independent VCCO supply, allowing mixed-voltage operation. Programmable drive strength (2–24 mA) and slew rate control are available per pin. The XC2S30-5VQ100C does not support differential signaling standards like LVDS or RSDS.
