Product details
Overview
XC2S15-5VQ100I from AMD (formerly Xilinx) is a Spartan-II family FPGA with 15,000 system gates, 176 logic cells, and 100-pin VQFP package. It operates at 5 ns maximum input-to-output delay, supports 3.3 V I/O, and targets low-cost digital logic replacement in industrial control and communication interface designs.
For engineers reviewing the XC2S15-5VQ100I datasheet, pinout, applications, or equivalent options, key selection criteria include logic density, I/O voltage compatibility, timing performance, and availability of configuration memory support.
Technical Context
The XC2S15-5VQ100I implements configurable logic blocks (CLBs) with four-input LUTs and flip-flops, distributed RAM up to 144 bits per CLB, and global clock routing with eight dedicated clock lines. It uses SRAM-based configuration and requires external PROM or processor for startup.
It supports IEEE 1149.1 JTAG boundary-scan testing, 3.3 V LVTTL/LVCMOS I/O standards, and programmable slew rate control on output drivers. Configuration occurs via Master Serial, Slave Serial, or SelectMAP modes.

FAQ
What is the configuration method supported by XC2S15-5VQ100I?
The XC2S15-5VQ100I supports Master Serial, Slave Serial, and SelectMAP configuration modes. Master Serial uses an external PROM to drive DIN and CCLK; Slave Serial allows a microcontroller to control configuration; SelectMAP enables parallel loading via 8- or 16-bit data bus. All methods load the same SRAM-based bitstream into the device.
Does XC2S15-5VQ100I require external configuration memory?
Yes, XC2S15-5VQ100I is SRAM-based and loses configuration on power loss. It requires external nonvolatile memory such as XCFxxP PROMs or microcontroller-managed flash to reload the bitstream at power-up. No internal configuration storage is present in the XC2S15-5VQ100I.
What I/O standards are compatible with XC2S15-5VQ100I?
XC2S15-5VQ100I supports LVTTL and LVCMOS 3.3 V I/O standards across its 84 user pins. Each I/O bank has independent VCCO supply, allowing mixed-voltage operation. It does not support 1.8 V, 2.5 V, or differential standards like LVDS or RSDS.
Can XC2S15-5VQ100I be used in new designs today?
Yes, XC2S15-5VQ100I remains viable for new designs where cost, proven reliability, and long-term supply are priorities over advanced features. AMD continues to support it with datasheets, software tools (ISE 14.7), and qualified sources for industrial and defense applications.
What is the maximum operating temperature range for XC2S15-5VQ100I?
The XC2S15-5VQ100I is rated for industrial temperature range: –40 °C to +85 °C ambient. This rating applies to the "I" speed grade and is verified per Xilinx DS001 specification. Thermal derating is required above 70 °C case temperature under sustained logic activity.
