It runs on a 1.65 V to 2.25 V supply rail and delivers a 55 ns access time — fast enough for cache or working memory in embedded systems that don't need the complexity of a synchronous interface. It's a surface-mount part — not something you swap in the field without a hot-air station and a steady hand. ## Supply and temperature envelope The 1.65 V to 2.25 V supply range lets this SRAM work with 1.8 V logic families directly, without a level shifter on the address and data lines. ## Board integration notes The 48-VFBGA (6x8 mm) package has a 0.5 mm ball pitch — typical for this density. The supplier device package is 48-VFBGA (6x8), so the footprint matches the standard JEDEC outline for 48-ball BGA SRAMs. Write cycle time matches the read access at 55 ns — no penalty for mixed read/write patterns. The parallel interface is straightforward: CE#, OE#, WE# control, with byte-select for the upper and lower byte lanes on the 16-bit bus.","metaTitle":"Infineon CY62147EV18LL-55BVXI SRAM, 4Mbit, 55ns, 48-VFBGA","metaDescription":"Active-production 4Mbit async SRAM from Infineon MoBL series. 256K x 16, 55ns access, 1.65-2.25V, -40 to +85°C. 48-VFBGA.","metaKeywords":null},"attributes":{"series":"MoBL®","packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Series":"MoBL®","Package":"Bulk","Technology":"SRAM - Asynchronous","Access Time":"55 ns","Memory Size":"4Mbit","Memory Type":"Volatile","Memory Format":"SRAM","Mounting Type":"Surface Mount","Package / Case":"48-VFBGA","lifecycle_stage":"eol_hot","Memory Interface":"Parallel","Voltage - Supply":"1.65V ~ 2.25V","Memory Organization":"256K x 16","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"48-VFBGA (6x8)","Write Cycle Time - Word, Page":"55ns"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.8","stockQuantity":0,"priceTiers":[{"qty":62,"price":"$4.86000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/5f96f5796520bee8565931d9a517bf61.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the memory organization and access time of this SRAM?","answer":"It's organized as 256K x 16 bits (4 Mbit total) with a 55 ns access time.
