Product details
Overview
XC6SLX25T-4CSG324C from AMD (formerly Xilinx) is a Spartan-6 FPGA featuring 24,051 logic cells, 18 Kbits of block RAM, and 186 user I/Os in a 324-pin CSGA package. It supports LVCMOS, LVTTL, SSTL, and HSTL I/O standards with differential signaling capability and operates at -4 speed grade (1.2 V core voltage). It is used in industrial control logic, motor drive sequencers, and compact video interface bridges.
For engineers reviewing the XC6SLX25T-4CSG324C datasheet, pinout, applications, or equivalent options, key selection criteria include logic density, I/O voltage flexibility, embedded DSP slice count, and availability of dedicated clock management tiles for deterministic timing closure.
Technical Context
The XC6SLX25T-4CSG324C implements a hierarchical FPGA architecture with configurable logic blocks (CLBs), distributed RAM, shift registers, and six 18×18 multipliers. It integrates two Digital Clock Managers (DCMs) supporting phase shifting, frequency synthesis, and duty cycle correction.
It supports SelectIO™ technology with programmable slew rate, drive strength, and on-chip termination (up to 50 Ω or 75 Ω). Configuration is performed via SPI, BPI, or JTAG interfaces, with support for dual-boot and fallback modes using external flash memory.
Key Specifications

Pinout & Package
XC6SLX25T-4CSG324C is housed in a 324-ball fine-pitch CSGA (Chip-Scale Grid Array) package with 1.0 mm ball pitch and 15 × 15 array configuration. Thermal pad on underside requires solder paste stencil design per Xilinx UG386.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| G1 | VCCO_0 | I/O bank 0 power supply - must be decoupled with 100 nF + 10 µF near ball |
| H2 | GCLK1 | Global clock input - routed to all DCMs and CLBs with low skew |
| K3 | M0 | Configuration mode select - sets boot source as SPI/BPI/JTAG during power-up |
| P14 | INIT_B | Open-drain status signal - goes high when configuration completes successfully |
| T15 | PROGRAM_B | Active-low reset - forces reconfiguration and clears internal SRAM contents |
Key Features
| Feature | Design Value |
|---|---|
| Dedicated clock routing | Eight global clock networks with <150 ps skew across die - ensures synchronous timing for multi-domain systems |
| Configurable I/O standards | Supports LVCMOS18/25/33, LVTTL, SSTL18_I/II, HSTL_I/II within same bank - eliminates level-shifter ICs |
| Dual-boot configuration | Enables fail-safe firmware update by storing primary and backup bitstreams in external flash - no external controller needed |

FAQ
What is the core voltage requirement for the XC6SLX25T-4CSG324C?
The XC6SLX25T-4CSG324C requires a nominal 1.2 V ±3% core supply (VCCINT) delivered through dedicated power pins. This voltage powers the FPGA fabric, CLBs, and internal interconnect. Deviation beyond tolerance risks timing violations or configuration loss. The XC6SLX25T-4CSG324C does not support dynamic voltage scaling - stable regulation is mandatory across all operating temperatures.
Does the XC6SLX25T-4CSG324C support JTAG boundary-scan testing?
Yes, the XC6SLX25T-4CSG324C fully complies with IEEE 1149.1 (JTAG) standard. It includes dedicated TCK, TMS, TDI, TDO, and TROUT pins for boundary-scan operation. The XC6SLX25T-4CSG324C supports INTEST, EXTEST, SAMPLE/PRELOAD, and BYPASS instructions, enabling PCB-level interconnect verification and in-system programming without requiring external debug probes.
Can the XC6SLX25T-4CSG324C be configured via SPI flash memory?
Yes, the XC6SLX25T-4CSG324C supports master SPI configuration mode using industry-standard serial NOR flash devices. It boots directly from SPI flash upon power-up when M[2:0] pins are set to 001. The XC6SLX25T-4CSG324C supports dual-boot with fallback to secondary image if CRC check fails - critical for field-upgradable industrial controllers.
How many differential I/O pairs does the XC6SLX25T-4CSG324C support?
The XC6SLX25T-4CSG324C supports up to 93 differential I/O pairs (186 total user I/Os), subject to bank voltage and IOSTANDARD constraints. Each pair can be assigned LVDS, RSDS, or BLVDS standards with programmable termination. The XC6SLX25T-4CSG324C requires matching VCCO and reference voltage (VREF) per bank to maintain signal integrity - no external resistors needed for on-die termination.
Is the XC6SLX25T-4CSG324C RoHS compliant and lead-free?
Yes, the XC6SLX25T-4CSG324C is RoHS 2011/65/EU compliant and manufactured with lead-free (Pb-free) terminations. The CSGA package uses matte tin plating over copper substrate. The XC6SLX25T-4CSG324C meets JEDEC J-STD-020 moisture sensitivity level 3 (MSL3) and requires bake conditioning before reflow if exposed beyond floor life.
