AMD XC3S200-4FT256C

Overview

XC3S200-4FT256C from AMD (formerly Xilinx) is a Spartan-3 FPGA with 200,000 system gates, 4,320 logic cells, and 216 I/O pins in a 256-pin Fine-Pitch Ball Grid Array (FBGA) package. It operates at -4 speed grade (t_PD = 4.5 ns), supports SelectIO™ standards up to 333 Mbps, and targets cost-sensitive embedded control and interface bridging applications.

For engineers reviewing the XC3S200-4FT256C datasheet, pinout, applications, or equivalent options, key selection factors include I/O voltage flexibility (1.2 V to 3.3 V), distributed RAM capacity (72 Kb), and support for DDR SDRAM interfaces up to 200 MHz.

Technical Context

The XC3S200-4FT256C implements a hierarchical FPGA architecture with configurable logic blocks (CLBs), dedicated multipliers, and block RAMs. It features eight global clock networks, digital clock managers (DCMs) for phase alignment and frequency synthesis, and supports JTAG boundary-scan testing per IEEE 1149.1.

Configuration is performed via Master Serial mode using external PROM or through JTAG. The device includes internal pull-up resistors on configuration pins and supports hot-swap compliant I/Os with programmable drive strength and slew rate control.

The Spartan-3 family was originally designed by Xilinx for cost-optimized, high-volume embedded systems requiring reconfigurable logic with low power and small footprint.

FAQ

What is the maximum operating frequency of the XC3S200-4FT256C?

The XC3S200-4FT256C supports internal logic operation up to 280 MHz under typical conditions. Its -4 speed grade guarantees CLB-to-CLB propagation delay ≤4.5 ns, enabling robust timing closure for designs targeting 200+ MHz system clocks with proper pipelining and placement constraints. The actual achievable frequency depends on design topology and I/O interface requirements.

Does the XC3S200-4FT256C support configuration via JTAG only?

No - the XC3S200-4FT256C supports multiple configuration modes including Master Serial (via external PROM), Slave Serial, Slave Parallel, and JTAG. JTAG is used primarily for debugging and in-system programming, while Master Serial is common for production deployment. All modes retain full access to the device's configuration memory and logic resources.

Can the XC3S200-4FT256C interface directly with DDR SDRAM?

Yes - the XC3S200-4FT256C supports DDR SDRAM interfaces up to 200 MHz using its SelectIO™ I/O standards and precise output delay control. It requires external termination and careful PCB layout but does not need external logic for strobe capture or write leveling. Reference designs and timing constraints are provided in Xilinx UG332.

What development tools are required to program the XC3S200-4FT256C?

Xilinx ISE Design Suite 14.7 is the last officially supported toolchain for the XC3S200-4FT256C. It includes synthesis, place-and-route, bitstream generation, and JTAG programming utilities. Third-party tools like GHDL or openFPGA flow may support limited RTL simulation but lack full timing closure and configuration support for this device.

Is the XC3S200-4FT256C RoHS compliant?

Yes - the XC3S200-4FT256C is manufactured in a RoHS-compliant process and meets EU Directive 2011/65/EU. Lead-free soldering profiles and moisture sensitivity level (MSL3) handling instructions are specified in the device's packaging documentation and Xilinx DS099.
