AMD XC2S15-5VQ100C

Overview

XC2S15-5VQ100C from AMD (formerly Xilinx) is a Spartan-II family FPGA with 15,000 system gates, 176 logic cells, 176 configurable logic blocks (CLBs), and 100-pin VQFP package. It operates at 5 ns propagation delay, supports 3.3 V I/O, and targets low-cost embedded control and interface bridging applications.

For engineers reviewing the XC2S15-5VQ100C datasheet, pinout, applications, or equivalent options, key selection criteria include CLB count, I/O voltage compatibility, maximum system clock frequency, and VQFP thermal performance in space-constrained industrial controllers.

Technical Context

The XC2S15-5VQ100C implements a hierarchical architecture with configurable logic blocks, 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 uses SRAM-based configuration memory and requires external configuration memory for power-up initialization.

Manufacturer

AMD acquired Xilinx in 2022 and maintains legacy Spartan-II product support for industrial and aerospace customers requiring long-lifecycle assurance.

The Spartan-II family was designed for cost-sensitive, high-volume embedded control and interface logic where predictable timing, low power, and mature toolchain support are critical.

FAQ

What is the maximum operating frequency of the XC2S15-5VQ100C?

The XC2S15-5VQ100C supports a maximum system clock frequency of 125 MHz under typical conditions. This value is derived from its 5 ns propagation delay specification and verified timing analysis in Xilinx ISE 14.7. The actual achievable frequency depends on design complexity, routing congestion, and I/O loading. XC2S15-5VQ100C users should perform static timing analysis using vendor tools to confirm timing closure for their specific implementation.

Does the XC2S15-5VQ100C support in-system programming?

Yes, the XC2S15-5VQ100C supports in-system programming via its IEEE 1149.1 JTAG interface (TCK/TMS/TDI/TDO pins). Configuration bitstreams can be loaded directly through JTAG without requiring external PROM, enabling field updates and debug reconfiguration. XC2S15-5VQ100C also supports indirect programming modes where JTAG controls an external serial PROM write cycle.

What power supply voltages does the XC2S15-5VQ100C require?

The XC2S15-5VQ100C requires two separate supply rails: 2.5 V ± 5% for the core logic and 3.3 V ± 10% for I/O banks. Each I/O bank has its own VCCO pin, allowing mixed-voltage operation across different banks. XC2S15-5VQ100C does not support single-supply operation; decoupling capacitors must be placed near each VCC and VCCO pin per Xilinx Spartan-II PCB layout guidelines.

Is the XC2S15-5VQ100C RoHS compliant?

The XC2S15-5VQ100C is available in both RoHS-compliant (lead-free) and non-RoHS versions. The "C" suffix indicates commercial temperature grade (0°C to 70°C), and RoHS status is defined by the full ordering part number suffix (e.g., -C with "G" or "I" suffix denotes lead-free). XC2S15-5VQ100C RoHS compliance must be verified against the specific date code and packaging label of the delivered unit.

Can the XC2S15-5VQ100C be used in automotive applications?

The XC2S15-5VQ100C is rated for commercial temperature range (0°C to 70°C) and is not qualified for automotive AEC-Q100 stress testing. While some customers have deployed XC2S15-5VQ100C in non-safety-critical cabin electronics, AMD/Xilinx does not guarantee operation beyond its specified temperature range or reliability under automotive vibration/thermal cycling profiles. XC2S15-5VQ100C is intended for industrial and consumer applications, not automotive-grade use.
