It operates from a single 4.5V to 5.5V supply rail, so it is not a 3.3V part — feeding it 3.3V will not meet the minimum supply and the memory will not function. ## 36-SOJ package — reworkable with care The 36-SOJ (BSOJ) package has gull-wing leads on a 0.400-inch body width (10.16 mm). It is surface-mount but hand-reworkable with hot air — the leads are visible and accessible for inspection and touch-up. ## Obsolete — sourcing options Infineon lists the CY7C1049BL-17VC as Obsolete. Because the part is no longer manufactured, availability is limited to existing distributor stock or the secondary market.","metaTitle":"CY7C1049BL-17VC Infineon 4Mbit Async SRAM 17 ns 36-SOJ","metaDescription":"CY7C1049BL-17VC Infineon 4Mbit (512K x8) asynchronous SRAM, 17 ns access time, 4.5V-5.5V, 0°C to 70°C, 36-SOJ.
