AMD XC3S200-4PQ208I

Overview

XC3S200-4PQ208I from AMD (formerly Xilinx) is a Spartan-3 FPGA with 200,000 system gates, 4,320 logic cells, and 208-pin PQFP packaging. It operates at -4 speed grade (tPD = 4.5 ns), supports 3.3 V I/O, and includes 173 Kbits of block RAM. It is used in industrial control logic, legacy interface bridging, and reconfigurable digital signal preprocessing.

For engineers reviewing the XC3S200-4PQ208I datasheet, pinout, applications, or equivalent options, key selection factors include logic cell count, I/O voltage compatibility, block RAM depth, speed grade timing margin, and legacy PQFP footprint availability for through-hole or rework-friendly designs.

Technical Context

The XC3S200-4PQ208I implements a hierarchical FPGA architecture with configurable logic blocks (CLBs), distributed RAM, and dedicated carry logic. It supports SelectIO standards including LVTTL, LVCMOS, and PCI, with programmable slew rate and drive strength per bank.

It integrates twelve 18×18 multipliers and four Digital Clock Managers (DCMs) for clock synthesis, phase shifting, and duty cycle correction-enabling synchronous design across multiple clock domains without external PLLs.

Key Specifications

Pinout & Package

XC3S200-4PQ208I uses a 208-pin Plastic Quad Flat Package (PQFP) with 0.5 mm pitch, 28 × 28 mm body size, and standard through-hole mounting compatibility. Thermal performance supports industrial temperature operation (-40°C to +100°C junction).

Compared with XC3S200-4PQ208I, the XC3S200A-4PQ208C reduces static power by ~35% at equivalent operating conditions but sacrifices industrial temperature rating, while XC3S400-4PQ208I doubles usable logic density without layout changes-enabling feature-rich upgrades without board revision.

Availability

XC3S200-4PQ208I is available at Aetrix Electronics and suitable for industrial motion control, legacy interface bridging, and reconfigurable signal preprocessing requiring stable component supply and long-term obsolescence mitigation.

Supply support for XC3S200-4PQ208I includes scheduled delivery planning, volume procurement assistance, BOM continuity management, traceable sourcing, and lifecycle availability coordination for OEM customers, industrial embedded developers, connected-device designers, and electronics production programs.

Manufacturer

AMD acquired Xilinx in 2022 and now manages the Spartan family as part of its adaptive computing portfolio. Xilinx pioneered FPGA architecture for reconfigurable digital logic before the acquisition.

The Spartan-3 family was designed for cost-sensitive, high-volume applications requiring reliable gate density, mature toolchain support, and industrial temperature resilience-targeting industrial automation, test equipment, and legacy system modernization.

FAQ

What is the maximum operating frequency supported by the XC3S200-4PQ208I?

The XC3S200-4PQ208I is rated at speed grade -4, with a guaranteed maximum input-to-output propagation delay (tPD) of 4.5 ns. This supports system clock frequencies up to 220 MHz for well-constrained critical paths. Actual achievable frequency depends on design complexity, routing, and DCM usage-verified timing analysis is required per implementation. The XC3S200-4PQ208I datasheet specifies this limit under industrial temperature and 1.2 V core voltage conditions.

Does the XC3S200-4PQ208I support JTAG programming?

Yes, the XC3S200-4PQ208I includes full IEEE 1149.1-compliant JTAG boundary-scan circuitry. Pins TCK, TMS, TDI, and TDO are dedicated for in-system programming, debugging, and interconnect testing. JTAG mode enables configuration without external PROM and supports partial reconfiguration in some toolflow versions. The XC3S200-4PQ208I requires no additional hardware beyond standard JTAG cabling for basic bitstream loading.

What I/O standards are supported by the XC3S200-4PQ208I?

The XC3S200-4PQ208I supports LVTTL, LVCMOS (3.3 V and 2.5 V), and PCI-compliant I/O standards through its SelectIO technology. Each of six I/O banks can be independently configured for voltage and standard. It does not support differential standards like LVDS or RSDS. The XC3S200-4PQ208I's I/O flexibility enables direct interfacing with microcontrollers, ADCs, and parallel memory without external level shifters.

Is the XC3S200-4PQ208I still in production?

The XC3S200-4PQ208I is discontinued by AMD (formerly Xilinx) but remains available through authorized distributors and Aetrix Electronics' legacy component program. It is subject to last-time-buy notifications and controlled allocation. Aetrix maintains traceable inventory with full documentation and supports long-term design continuity for industrial customers relying on the XC3S200-4PQ208I.

Can the XC3S200-4PQ208I be used in place of the XC3S200-4TQ144I?

No-the XC3S200-4PQ208I and XC3S200-4TQ144I differ in package type, pin count, and I/O count. The PQ208 has 208 pins and 141 user I/Os; the TQ144 has 144 pins and 108 user I/Os. They share the same logic resources and speed grade, but PCB layout, power delivery, and thermal design are not interchangeable. Replacing one with the other requires full schematic and layout revision. The XC3S200-4PQ208I cannot serve as a drop-in substitute for the XC3S200-4TQ144I.
