AMD XC2S100-6PQ208C

Overview

XC2S100-6PQ208C from AMD (formerly Xilinx) is a Spartan-II family FPGA with 100,000 system gates, 1728 logic cells, and 128 I/O pins in a 208-pin PQFP package. It operates at 6 ns CLB delay and supports 3.3 V I/O with 2.5 V core voltage, used in industrial control logic and digital signal preprocessing.

For engineers reviewing the XC2S100-6PQ208C datasheet, pinout, applications, or equivalent options, key selection factors include logic density, I/O count, speed grade (-6), PQFP thermal profile, and legacy configuration interface support.

Technical Context

The XC2S100-6PQ208C implements configurable logic blocks (CLBs) with four-input LUTs and flip-flops, distributed RAM up to 144 Kbits, and global clock networks with eight dedicated clock lines. It uses SRAM-based configuration and requires external PROM or processor for startup.

Configuration occurs via JTAG (IEEE 1149.1) or master/slave serial mode using SelectMAP or boundary-scan interfaces. No on-chip oscillator or analog features are integrated; all timing relies on external clocks.

XC2S100-6PQ208C is available at Aetrix Electronics and suitable for industrial motion control, digital video preprocessing, and legacy protocol bridge applications requiring stable component supply and long-term obsolescence management.

Supply support for XC2S100-6PQ208C includes scheduled delivery planning, volume procurement assistance, BOM continuity management, traceable sourcing, and lifecycle availability coordination for OEM customers, industrial embedded developers, connected-device designers, and electronics production programs.

Manufacturer

AMD acquired Xilinx in 2022 and maintains legacy Spartan-II product support, documentation, and cross-reference compatibility for industrial and aerospace customers.

The Spartan-II family was designed for cost-sensitive, high-volume embedded logic replacement-emphasizing predictable timing, broad I/O flexibility, and mature 0.18 µm CMOS process reliability.

FAQ

What is the configuration method supported by XC2S100-6PQ208C?

The XC2S100-6PQ208C supports three configuration modes: JTAG (IEEE 1149.1) for debugging and programming, Master Serial using an external PROM, and SelectMAP for parallel loading from a microprocessor. It does not support internal configuration memory or single-chip boot.

Does XC2S100-6PQ208C include built-in clock generation circuitry?

No, the XC2S100-6PQ208C has no PLL, DLL, or on-chip oscillator. It relies entirely on external clock sources fed into its eight global clock inputs (GCK0–GCK7), with timing closure dependent on board-level clock distribution design.

What I/O standards are compatible with XC2S100-6PQ208C?

The XC2S100-6PQ208C supports LVTTL and LVCMOS33 I/O standards at 3.3 V, with programmable drive strength and slew rate control per bank. It does not support 1.8 V, 2.5 V, or differential standards like LVDS or RSDS.

Is XC2S100-6PQ208C still in active production?

The XC2S100-6PQ208C is obsolete per AMD/Xilinx PCN notices, but Aetrix Electronics maintains verified legacy inventory with full traceability and extended lifecycle support for existing designs and repair programs.

Can XC2S100-6PQ208C be reprogrammed in-system?

Yes, the XC2S100-6PQ208C supports in-system programming via JTAG or SelectMAP interfaces. Reprogramming requires external configuration data source and does not alter the device's PQ208 package or pinout behavior.
