AMD XC2S100-5PQG208C

Overview

XC2S100-5PQG208C from AMD (formerly Xilinx) is a Spartan-II family FPGA with 100,000 system gates, 117 I/O pins, and 432 CLBs. It features 40 ns global clock delay, supports 3.3 V I/O, and operates at -5 speed grade (5 ns TPD). It is used in industrial control logic replacement and low-cost digital signal preprocessing.

For engineers reviewing the XC2S100-5PQG208C datasheet, pinout, applications, or equivalent options, key selection factors include I/O count, CLB density, speed grade timing compliance, and QFP package thermal profile for reflow-suitable PCB assembly.

Technical Context

The XC2S100-5PQG208C implements configurable logic blocks (CLBs) with dual 4-input LUTs and flip-flops per slice, supporting synchronous design with dedicated carry chains and distributed RAM. Its SelectIO interface supports LVTTL, LVCMOS, and PCI-compliant signaling across all 117 user I/O pins.

It uses a 5V-tolerant, 3.3V core voltage architecture with internal voltage regulation and supports JTAG boundary-scan (IEEE 1149.1) for configuration and test. Configuration is performed via serial PROM or master parallel mode using external memory.

FAQ

What is the core voltage requirement for XC2S100-5PQG208C?

The XC2S100-5PQG208C requires a regulated 2.5 V ± 3% supply for its core logic. This is separate from the 3.3 V I/O supply. Proper decoupling with 100 nF ceramic capacitors near each VCCINT pin is mandatory to ensure stable operation under dynamic switching loads. The XC2S100-5PQG208C does not regulate core voltage internally.

Does XC2S100-5PQG208C support JTAG configuration?

Yes, XC2S100-5PQG208C fully supports IEEE 1149.1 JTAG boundary-scan for configuration, debugging, and interconnect testing. The TCK, TMS, TDI, and TDO pins are dedicated and electrically compatible with standard JTAG programmers. JTAG mode can be used for both initial programming and in-system reconfiguration of the XC2S100-5PQG208C.

What is the maximum operating frequency of XC2S100-5PQG208C?

The XC2S100-5PQG208C is rated for a 200 MHz global clock input (5 ns TPD), verified by worst-case timing analysis across voltage and temperature. Actual system clock frequency depends on design topology and routing; typical synchronous logic paths achieve 120–160 MHz in well-optimized implementations. The XC2S100-5PQG208C does not include PLLs or DLLs to multiply or clean clocks.

Can XC2S100-5PQG208C drive 5 V TTL inputs?

No, XC2S100-5PQG208C I/O banks operate at 3.3 V and are not 5 V tolerant. Driving 5 V TTL inputs requires external level-shifting circuitry. The XC2S100-5PQG208C supports LVTTL and LVCMOS standards only, with VIH(min) = 2.0 V and VIL(max) = 0.8 V at 3.3 V VCCO. Direct connection to 5 V logic may damage the XC2S100-5PQG208C.

Is XC2S100-5PQG208C RoHS compliant?

Yes, XC2S100-5PQG208C is RoHS-6 compliant (lead-free, mercury-free, cadmium-free, hexavalent chromium-free, PBB-free, PBDE-free) and meets JEDEC J-STD-020 moisture sensitivity level 3 (MSL-3) requirements. The PQG208 package uses matte tin lead finish and complies with IPC/JEDEC J-STD-033 handling guidelines. Documentation for the XC2S100-5PQG208C confirms full RoHS conformance.
