Housed in a 36-SOJ (Small Outline J-lead) package with a 10.16 mm body width, this surface-mount part requires a standard SOJ footprint. The J-lead form factor offers good solder-joint reliability under thermal cycling, though the package is less common than SOIC — verify stencil aperture and reflow profile with your assembly house before committing the BOM. Supplied in Tape & Reel, it is ready for automated pick-and-place in volume production.","metaTitle":"Infineon CY7C1049G-10VXIT 4Mbit Async SRAM, 10 ns, 36-SOJ","metaDescription":"Infineon CY7C1049G-10VXIT 4Mbit asynchronous SRAM with 10 ns access time, 512K x 8 organization, 4.5V-5.5V supply.
