Product details
Overview
XC2S50-6FG256C from AMD (formerly Xilinx) is a Spartan-II family FPGA with 50,000 system gates, 176 logic cells, 28 I/O pins, and a 6 ns maximum input-to-output delay. It integrates configurable logic blocks, distributed RAM, and global clock networks for digital logic implementation in industrial control and communication interface designs.
For engineers reviewing the XC2S50-6FG256C datasheet, pinout, applications, or equivalent options, key selection criteria include I/O count, speed grade (-6), package footprint (FBGA256), configuration mode support, and embedded RAM capacity.
Technical Context
The XC2S50-6FG256C implements synchronous digital logic using 4-input LUTs and flip-flops per CLB, with dedicated carry chains for arithmetic functions. It supports JTAG boundary-scan testing and in-system programmability via SelectMAP or slave serial configuration modes.
Configuration is loaded from external PROM or processor-controlled interface; no on-chip nonvolatile memory is integrated. The -6 speed grade specifies guaranteed timing performance up to 166 MHz for internal register-to-register paths under commercial temperature conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |

| CLBs | 176 configurable logic blocks - each contains two 4-LUTs and two registers for sequential logic |
| I/O Pins | 28 user I/O pins - supports parallel bus interfaces and multi-signal control channels |
| Speed Grade | -6 - guarantees 6 ns input-to-output delay and 166 MHz register-to-register frequency |
| Package | FBGA256 - 17×17 mm fine-pitch ball grid array with 256 solder balls |
| Operating Temp | 0°C to 85°C - commercial temperature range suitable for non-automotive indoor applications |
Pinout & Package
XC2S50-6FG256C uses a 256-ball Fine-Pitch Ball Grid Array (FBGA) package with 1.0 mm ball pitch and 17×17 ball array. Pin assignment follows Xilinx Spartan-II pinout standard for FG256 package.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCCO_0 | I/O bank power supply | Supplies 3.3 V to Bank 0 I/Os; must be decoupled locally |
| GND | Ground reference | Provides signal return path; multiple balls assigned for low-inductance grounding |
| PROGRAM_B | Active-low configuration initiator | Pulls low to reset configuration logic and reload bitstream from external source |
| DONE | Configuration status indicator | Open-drain output goes high when configuration completes successfully |
| TCK/TMS/TDI/TDO | JTAG test interface | Enables IEEE 1149.1 boundary-scan testing and programming without dedicated programmer |
Key Features
| Feature | Design Value |
|---|---|
| Configurable Logic Blocks (CLBs) | 176 CLBs each with dual 4-LUTs and flip-flops enable efficient state machine and datapath implementation |
| Distributed RAM | 176 × 16-bit synchronous RAM per CLB allows small FIFOs and register files without block RAM |
| Global Clock Networks | Four low-skew global clock buffers support synchronous design across large logic regions |

Equivalent & Alternatives
The following parts are listed as comparable options for similar FPGA logic implementation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| XC2S50-5FG256C | Slower -5 speed grade (7 ns delay, 140 MHz max); identical logic resources and package | Suitable for lower-frequency control loops where timing margin is relaxed | Select XC2S50-5FG256C only if design meets timing at reduced clock rates to lower cost |
| XC3S50-4PQ208C | Spartan-3 family; 50K gates, -4 speed, PQ208 package (208-pin PQFP); higher logic density per CLB | Requires PCB redesign due to different package and pinout; supports enhanced features like DSP slices | XC3S50-4PQ208C offers better future scalability but mandates layout change and toolchain update |
Compared with XC2S50-5FG256C, the XC2S50-6FG256C delivers tighter timing closure for high-speed I/O; versus XC3S50-4PQ208C, it retains legacy board compatibility but lacks advanced routing and embedded multipliers.

FAQ
What is the configuration method supported by XC2S50-6FG256C?
The XC2S50-6FG256C supports master serial, slave serial, and SelectMAP configuration modes using external PROM or microprocessor. It does not include on-chip flash; configuration bitstream must be loaded at power-up. JTAG is available for programming and debugging. XC2S50-6FG256C requires external memory or host controller to store and deliver configuration data.
Does XC2S50-6FG256C include embedded block RAM?
No, XC2S50-6FG256C does not contain dedicated block RAM resources. It provides only distributed RAM within CLBs - 16 bits per CLB - suitable for small shift registers or lookup tables. Larger memory functions require external SRAM or use of multiple CLBs, limiting depth to ~176×16 bits. XC2S50-6FG256C relies on external memory for frame buffers or FIFOs exceeding this capacity.
What voltage levels are supported on XC2S50-6FG256C I/O banks?
XC2S50-6FG256C supports 3.3 V LVTTL and LVCMOS I/O standards exclusively. Each I/O bank requires a dedicated VCCO supply at 3.3 V; mixed-voltage operation across banks is not supported. Input thresholds and drive strength are fixed per bank and cannot be reconfigured to 2.5 V or 1.8 V. XC2S50-6FG256C is incompatible with lower-voltage interfaces without level-shifting circuitry.
Is XC2S50-6FG256C RoHS compliant?
Yes, XC2S50-6FG256C is RoHS compliant and lead-free, meeting EU Directive 2011/65/EU. The FBGA256 package uses matte tin finish on solder balls. This applies to all currently distributed lots. XC2S50-6FG256C meets environmental compliance requirements for industrial and commercial end equipment without exemption requests.
Can XC2S50-6FG256C operate in extended temperature ranges?
No, XC2S50-6FG256C is rated only for commercial temperature range (0°C to +85°C). It is not qualified for industrial (-40°C to +100°C) or automotive temperature grades. Operation outside 0–85°C may result in timing violations or configuration loss. XC2S50-6FG256C requires thermal management in enclosed enclosures to maintain ambient within specification.
