AMD XC3S200-4PQG208C

Overview

XC3S200-4PQG208C from AMD (formerly Xilinx) is a Spartan-3 FPGA with 200,000 system gates, 4,320 logic cells, 128 KB of block RAM, and operates at -4 speed grade (5 ns CLB delay). It features 160 user I/Os in a 208-pin PQFP package and is used in industrial control logic, digital video interface bridging, and reconfigurable peripheral controllers.

For engineers reviewing the XC3S200-4PQG208C datasheet, pinout, applications, or equivalent options, key selection factors include logic density, I/O count, embedded RAM capacity, speed grade timing closure, and QFP thermal and routing constraints.

Technical Context

The XC3S200-4PQG208C implements a hierarchical FPGA architecture with configurable logic blocks (CLBs), distributed RAM, and dedicated carry logic for arithmetic. It supports SelectIO standards including LVCMOS, LVTTL, PCI, and SSTL-2.

Configuration is performed via Master Serial mode using an external PROM or through JTAG boundary-scan. The device includes Digital Clock Managers (DCMs) supporting frequency synthesis, phase shifting, and duty cycle correction across up to four independent clock domains.

FAQ

What is the maximum operating frequency supported by the XC3S200-4PQG208C?

The XC3S200-4PQG208C has a -4 speed grade, guaranteeing a 5 ns CLB propagation delay. Maximum system clock frequency depends on design topology but typically achieves 150–200 MHz for fully pipelined logic paths. DCM outputs can generate clocks up to 240 MHz with proper jitter filtering and load matching. Always validate timing closure using Xilinx ISE 14.7 for the XC3S200-4PQG208C.

Does the XC3S200-4PQG208C support JTAG programming?

Yes, the XC3S200-4PQG208C supports IEEE 1149.1 JTAG boundary-scan via TCK, TMS, TDI, and TDO pins. This enables in-system programming, debugging, and verification without requiring external configuration PROMs. JTAG mode is active after power-up and remains available throughout operation for partial reconfiguration and diagnostics.

What power supplies are required for the XC3S200-4PQG208C?

The XC3S200-4PQG208C requires three independent supplies: VCCINT = 1.2 V ±3% for core logic, VCCAUX = 3.3 V ±5% for auxiliary circuits (DCMs, JTAG), and VCCO = 3.3 V or 2.5 V (per I/O bank) for output drivers. Each supply must be locally decoupled with 100 nF ceramic capacitors placed within 10 mm of respective power pins.

Can the XC3S200-4PQG208C be configured using a serial PROM?

Yes, the XC3S200-4PQG208C supports Master Serial configuration mode using industry-standard Xilinx Platform Flash PROMs (e.g., XCF02S). Configuration bitstream is loaded automatically on power-up via dedicated PROM interface pins (DIN, CCLK, INIT_B, DONE). This method eliminates host processor dependency and enables autonomous startup.

Is the XC3S200-4PQG208C RoHS compliant?

Yes, the XC3S200-4PQG208C is RoHS-6 compliant (lead-free, halogen-free) and meets JEDEC J-STD-020 moisture sensitivity level 3 (MSL3) requirements. The PQG208 package uses matte tin lead finish and complies with IPC/JEDEC J-STD-033 handling guidelines for reflow soldering and storage.
