The 102 user I/O count matches the 144-pin LQFP footprint — roughly 70 % of the pins are signal, the rest are core/aux supply and ground. That pin density drives the breakout: a two-layer board can route the outer rows, but the inner VCCINT and GND pairs need a power plane or wide traces to keep IR drop under 30 mV at 1.2 V. ## Industrial temp range and core supply — what the numbers mean for your regulator and heatsink The 1.14 V to 1.26 V core supply is tight: a 1.2 V rail with ±5 % tolerance stays inside the window, but a 1.2 V rail at ±3 % (common for POL converters) gives 36 mV of headroom each way. ## Active lifecycle — no LTB clock, design-in safe ROHS3 compliant (no exempt substances) — the assembly line does not need a waiver for lead or phthalates. The tray packaging is standard for 144-TQFP; reels are available through the same supply channel for volume pick-and-place.","metaTitle":"XC6SLX4-2TQG144I Spartan-6 LX FPGA, 3840 cells, 102 I/O","metaDescription":"XC6SLX4-2TQG144I Spartan-6 LX FPGA with 3840 logic cells, 102 I/O, 216 Kbit block RAM in 144-TQFP.
