Product details
Overview
XC2S50-5FG256C from AMD (formerly Xilinx) is a Spartan-II family FPGA with 50,000 system gates, 176 logic cells, and 28 I/O pins in a 256-pin Fine-Pitch Ball Grid Array (FBGA) package. It operates at 5 V supply voltage with -5 speed grade (5 ns CLB delay), targeting low-cost digital logic control and interface bridging in industrial PLCs and sensor hubs.
For engineers reviewing the XC2S50-5FG256C datasheet, pinout, applications, or equivalent options, key selection criteria include I/O count, CLB delay, supply voltage tolerance, configuration mode support (Master Serial, Slave Parallel), and JTAG boundary-scan compliance for production testability.
Technical Context
The XC2S50-5FG256C implements configurable logic blocks (CLBs) with dual 4-input LUTs and flip-flops per slice, supporting synchronous logic with global clock routing and three dedicated clock inputs. It uses SRAM-based configuration memory loaded via JTAG or serial PROM, requiring external configuration on power-up.
It supports SelectIO™ standards including LVTTL, LVCMOS, and PCI-compliant signaling across its 28 user I/O pins, with programmable slew rate and drive strength per bank. Configuration is non-volatile only when paired with external PROM; internal configuration memory is volatile.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Capacity | 50,000 system gates - defines maximum combinational logic density for gate-equivalent design mapping |
| CLB Count | 176 CLBs - determines number of synchronous logic units available for state machine or pipeline implementation |
| I/O Pins | 28 user-configurable I/O - supports discrete signal interfacing without external glue logic |
| Speed Grade | -5 (5 ns CLB propagation delay) - sets maximum operating frequency for critical path timing closure |
| Supply Voltage | 5.0 V ±10% - requires standard 5 V regulator; not compatible with 3.3 V or mixed-voltage I/O domains |
| Configuration Mode | Master Serial, Slave Parallel, JTAG - enables flexible programming during development and in-system reconfiguration |
Pinout & Package
XC2S50-5FG256C is housed in a 256-pin Fine-Pitch Ball Grid Array (FBGA) package with 1.0 mm ball pitch, 17 mm × 17 mm body size, and thermal pad exposed on underside for enhanced heat dissipation in sustained logic operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| P1 | VCCO_0 | I/O bank 0 power supply - must be decoupled locally to maintain signal integrity for LVTTL outputs |
| R2 | TCK | JTAG test clock input - synchronizes boundary-scan operations during programming and debug |
| T3 | TMS | JTAG test mode select - controls state transitions in TAP controller for configuration access |
| U4 | TDO | JTAG test data output - returns configuration status or register readback data serially |
| V5 | TDI | JTAG test data input - accepts bitstream or command data for device programming |
| W6 | PROGRAM_B | Active-low configuration reset - forces reinitialization and reloads bitstream from external PROM |
Key Features
| Feature | Design Value |
|---|---|
| Dual 4-input LUT per CLB slice | Enables efficient implementation of arithmetic functions and wide multiplexers without cascading logic levels |
| Three dedicated global clock inputs | Reduces clock skew across large logic regions and supports multi-domain clocking in control systems |
| Programmable I/O drive strength (2 mA / 4 mA / 8 mA / 12 mA) | Allows optimization of EMI and signal rise/fall times for different trace lengths and load capacitances |
| JTAG boundary-scan (IEEE 1149.1) | Supports in-circuit verification, interconnect testing, and post-assembly fault diagnosis without physical probe access |
| SelectIO™ technology | Per-bank voltage referencing enables mixed-signaling (e.g., LVTTL I/O with 5 V core) within single device |

Equivalent & Alternatives
The following parts are listed as comparable options for similar FPGA logic implementation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| XC2S50-6FG256C | Faster -6 speed grade (4.5 ns CLB delay); identical pinout and logic resources | Better suited for higher-frequency control loops or tighter timing margins | Select when target system clock exceeds 125 MHz or setup/hold slack is marginal with -5 grade |
| XC2S100-5FG256C | Higher density (100K gates, 352 CLBs); same package and voltage | Supports larger state machines or additional peripheral interfaces without board redesign | Choose when future firmware expansion or added I/O functionality is anticipated in same footprint |
Compared with XC2S50-5FG256C, the XC2S50-6FG256C offers improved timing margin at identical cost and layout, while XC2S100-5FG256C provides headroom for logic growth without changing PCB or power delivery - both retain full JTAG and configuration compatibility.

Manufacturer
AMD acquired Xilinx in 2022 and continues to support legacy Spartan-II devices through authorized distribution channels and archived documentation.
The Spartan-II family was designed for cost-sensitive, high-volume applications requiring moderate logic density and 5 V system integration - especially where pin-compatible migration paths and mature toolchain support were essential.
FAQ
What configuration methods does XC2S50-5FG256C support?
XC2S50-5FG256C supports Master Serial (via on-chip oscillator and external PROM), Slave Parallel (using host processor data bus), and IEEE 1149.1 JTAG boundary-scan modes. All three methods allow full bitstream loading and verification. The JTAG interface is always active and does not require prior configuration, making it ideal for factory programming and field updates. XC2S50-5FG256C does not support slave serial or network-based configuration.
Is XC2S50-5FG256C RoHS compliant?
XC2S50-5FG256C was originally manufactured before RoHS Directive 2002/95/EC enforcement and is classified as non-RoHS (lead-containing). It remains available through legacy distribution channels with full traceability but is not suitable for new designs targeting EU WEEE/RoHS compliance. XC2S50-5FG256C has no lead-free variant in the Spartan-II family.
Can XC2S50-5FG256C operate at 3.3 V?
No, XC2S50-5FG256C requires a nominal 5.0 V ±10% core and I/O supply. Its internal circuitry and I/O buffers are not rated for 3.3 V operation. Attempting 3.3 V supply will result in configuration failure, logic instability, or permanent damage. XC2S50-5FG256C must be powered from a regulated 5 V source with appropriate decoupling.
Does XC2S50-5FG256C include internal configuration memory?
XC2S50-5FG256C uses volatile SRAM-based configuration memory and does not retain its programmed logic state after power loss. It requires external non-volatile storage (e.g., XCF01S or similar serial PROM) to reload the bitstream on each power-up. XC2S50-5FG256C has no embedded flash or antifuse elements - configuration is always external and dynamic.
What software tools support XC2S50-5FG256C design and programming?
XC2S50-5FG256C is supported exclusively by Xilinx ISE Design Suite versions up to 14.7. Synthesis, place-and-route, and bitstream generation require ISE WebPACK or full licensed editions. Programming is performed via iMPACT or third-party JTAG tools compatible with IEEE 1149.1. Vivado does not support Spartan-II devices; XC2S50-5FG256C cannot be targeted in modern Xilinx toolchains.
