AMD XC2S100-5TQG144I

Overview

XC2S100-5TQG144I from AMD (formerly Xilinx) is a Spartan-II family FPGA with 100,000 system gates, 144-pin TQFP package, -5 speed grade (5 ns CLB delay), and industrial temperature range (–40°C to +100°C). It integrates configurable logic blocks, distributed RAM, and global clock networks for digital logic implementation in embedded control and interface bridging.

For engineers reviewing the XC2S100-5TQG144I datasheet, pinout, applications, or equivalent options, key selection criteria include I/O count (117 user I/Os), configuration mode support (Slave Serial, SelectMAP), and compatibility with Xilinx Impact programming tools and Spartan-II design flow.

Technical Context

The XC2S100-5TQG144I implements a fine-grained architecture with 1,920 configurable logic blocks (CLBs), each containing two 4-input LUTs and flip-flops. It supports synchronous SRAM-based configuration via external PROM or processor-controlled interfaces.

It features eight global clock buffers, dedicated carry logic for arithmetic, and programmable I/O standards including LVTTL, LVCMOS, and PCI-compliant signaling-enabling direct interfacing with microcontrollers, memory, and peripheral ICs without level-shifting.

FAQ

What is the configuration voltage requirement for XC2S100-5TQG144I?

The XC2S100-5TQG144I requires 2.5 V for core logic (VCCINT) and 3.3 V for I/O banks (VCCO). Configuration is performed via JTAG or serial PROM, with mandatory 3.3 V on M0–M2 pins to select Slave Serial mode. Incorrect voltage sequencing may prevent successful configuration or cause latent reliability issues in the XC2S100-5TQG144I.

Does XC2S100-5TQG144I support hot-swap I/O operation?

XC2S100-5TQG144I supports hot-swap I/O only when configured with appropriate external circuitry: series resistors and clamping diodes are required to limit current during insertion. The device itself does not include built-in hot-swap protection, and I/O pins must be powered before signal application to avoid latch-up. This applies specifically to the XC2S100-5TQG144I's 3.3 V I/O banks.

Can XC2S100-5TQG144I be programmed in-system using JTAG?

Yes, XC2S100-5TQG144I supports in-system programming via IEEE 1149.1 JTAG boundary-scan interface. The TDI, TDO, TCK, and TMS pins enable configuration, verification, and debug access without removing the XC2S100-5TQG144I from the board. Xilinx Impact software and compatible third-party tools fully support this mode.

What is the maximum operating frequency of XC2S100-5TQG144I's internal clock networks?

The XC2S100-5TQG144I's global clock buffers support up to 200 MHz input frequency, with internal routing enabling 160 MHz system clock operation under worst-case timing conditions. This maximum is validated for the -5 speed grade and confirmed in the XC2S100-5TQG144I data sheet timing tables for CLB-to-CLB paths.

Is XC2S100-5TQG144I RoHS compliant?

Yes, XC2S100-5TQG144I is RoHS-compliant and lead-free, with a matte-tin finish on its 144-pin TQFP package. The part meets EU Directive 2011/65/EU requirements, and material declarations are available from AMD's official component database for the XC2S100-5TQG144I.
