The J-leads are visible and accessible to a hot-air station, making hand rework straightforward — no hidden balls, no underfill. The 10.16 mm width fits standard SOJ footprints; verify the pad pitch against your existing layout if replacing a 32-pin or 44-pin SOJ part. The package ships in Tube, so plan for pick-and-place feeder changeover if your line runs tape-and-reel exclusively. ## Temperature grade and supply — where it works At 5 V the 10 ns timing is specified; dropping to 4.5 V may add a small derating, though the datasheet holds the same 10 ns across the full range. For dual-sourcing resilience, the CY7C1049G-10VXI is a functional equivalent — same 4 Mbit density, 10 ns speed, 5 V supply, and 36-SOJ package — differing only in the lead-free finish code (the 'GN' suffix indicates NiPdAu plating).","metaTitle":"Infineon CY7C1049GN-10VXI SRAM, 4 Mbit, 10 ns, 36-SOJ","metaDescription":"Infineon CY7C1049GN-10VXI asynchronous SRAM, 4 Mbit (512K x 8), 10 ns access time, 4.5 V to 5.5 V, -40°C to 85°C, 36-SOJ.
