It operates from a 4.5 V to 5.5 V supply and is housed in a 36-SOJ surface-mount package. Write cycle time is also 15 ns. The CY7C1049B-15VXC is obsolete per the manufacturer's lifecycle status. No last-time-buy window remains open through Cypress (now Infineon). The 36-SOJ (Small Outline J-Lead) package has a 0.400-inch body width and a 10.16 mm width. It is a surface-mount footprint that was common in late-1990s through 2010s telecom and networking line cards.","metaTitle":"Cypress CY7C1049B-15VXC SRAM, 4Mbit, 15ns, 36-SOJ","metaDescription":"Cypress CY7C1049B-15VXC 4Mbit asynchronous SRAM, 512K x 8, 15ns access time, 4.5V–5.5V supply, 36-SOJ, 0°C–70°C.
