AMD XC3S200A-4FTG256C

Overview

XC3S200A-4FTG256C from AMD (formerly Xilinx) is a Spartan-3A FPGA with 200,000 system gates, 4,032 logic cells, 180 I/O pins, and embedded block RAM totaling 360 kbits. It operates at -4 speed grade (1.14 ns CLB delay), uses 1.2 V core voltage, and is packaged in a 256-pin Fine-Pitch Thin Quad Flatpack (FTBGA) with 0.8 mm pitch. It targets cost-sensitive industrial control and communication interface logic.

For engineers reviewing the XC3S200A-4FTG256C datasheet, pinout, applications, or equivalent options, key selection criteria include I/O count, block RAM depth, speed grade timing closure, and FTBGA256 thermal/mechanical compatibility with existing PCB layouts.

Technical Context

This FPGA implements configurable logic blocks (CLBs) with four-input LUTs and flip-flops, distributed RAM, and dedicated carry logic for arithmetic. It integrates eighteen 18×18 multipliers and supports SelectIO standards including LVCMOS, LVTTL, PCI, and SSTL.

The device includes internal configuration logic supporting Master Serial, Slave Serial, and JTAG modes. Configuration bitstream is loaded into SRAM-based configuration memory, requiring external nonvolatile storage for power-up initialization.

FAQ

What is the maximum operating frequency supported by XC3S200A-4FTG256C?

The XC3S200A-4FTG256C is rated at speed grade -4, guaranteeing a 1.14 ns CLB propagation delay. Achievable system clock frequencies depend on design topology, but synchronous paths can reach up to 280 MHz under typical conditions. Timing analysis must be performed using Xilinx ISE software with the -4 speed model to verify closure for each specific implementation of XC3S200A-4FTG256C.

Does XC3S200A-4FTG256C support JTAG boundary scan?

Yes, XC3S200A-4FTG256C includes full IEEE 1149.1 JTAG support via dedicated TCK, TMS, TDI, and TDO pins. This enables in-system programming, configuration verification, and interconnect testing during production and field service. The JTAG chain can also be used to configure multiple devices, including XC3S200A-4FTG256C, in a single daisy-chain setup.

Can XC3S200A-4FTG256C be configured using SPI flash memory?

No, XC3S200A-4FTG256C does not support native SPI master mode for configuration. It requires external serial PROM (e.g., XCFxxP series) programmed with the .bit file, or use of a microcontroller in slave serial mode. The configuration interface is Master Serial (via DONE and INIT_B) or Slave Serial (via DIN/DOUT), not SPI-compatible without external translation logic.

What I/O standards are supported by XC3S200A-4FTG256C?

XC3S200A-4FTG256C supports SelectIO standards per I/O bank, including LVCMOS 1.2/1.5/1.8/2.5/3.3 V, LVTTL, PCI, and SSTL18. Each bank's VCCO voltage determines allowable standards, and banks may operate at different voltages simultaneously. This enables direct interfacing with diverse peripherals without level-shifting components in many XC3S200A-4FTG256C deployments.

Is XC3S200A-4FTG256C still in active production?

XC3S200A-4FTG256C is in continued production under AMD's longevity program for industrial and embedded applications. While newer families like Artix-7 have superseded it in performance, AMD maintains committed supply for this part through authorized distribution channels. Customers designing new systems should verify current status via AMD's Product Change Notification (PCN) portal before finalizing XC3S200A-4FTG256C in BOMs.
