It's part of the MoBL® (More Battery Life) family, though this 5V variant targets industrial bus-memory and cache applications rather than ultra-low-power handhelds. The 55 ns access time sets the read-cycle floor for the host controller — at 55 ns, the bus margin is comfortable for 8- and 16-bit microcontrollers running at 20 MHz and below, but a faster 10 ns part like the CY7C1049G-10VXI would be needed if the controller pulls back-to-back reads at higher clock rates. For a typical 8-bit MCU at 16 MHz (62.5 ns cycle), the SRAM's 55 ns leaves about 7.5 ns of setup margin before the next clock edge — tight but workable with 5V logic. If the design uses a 32-bit bus or a faster processor, the 55 ns part will force wait states. This part is a fit for legacy 5V systems where speed isn't the bottleneck. ## Package and supply rails Housed in a 32-SOIC (300 mil wide, 11.30 mm body width). The supply range is 4.5V to 5.5V — straight 5V rail, no 3.3V or 1.8V option. ROHS3 compliant. Surface-mount only. ## Lifecycle and sourcing posture The 55 ns speed grade is the slowest in the MoBL® 4Mbit family — if your BOM originally called the CY62148ELL-70SXI (70 ns), the 55 ns part is a drop-in replacement with margin, but verify the write-cycle timing in your specific controller's memory controller.","metaTitle":"Infineon CY62148ELL-55SXI SRAM, 4Mbit, 55 ns, 32-SOIC","metaDescription":"Infineon CY62148ELL-55SXI asynchronous SRAM, 4Mbit (512K x 8), 55 ns access, -40°C to 85°C.
