The 100 MHz clock rate and 8.5 ns access time place it in the mid-range speed bin for this density — suitable for cache, buffer, or look-up table applications where the bus clock runs at or below 100 MHz and the 8.5 ns window covers the address-to-data latency. ## Temperature grade and supply voltage The supply range is 3.135 V to 3.6 V — a 3.3 V nominal rail with ±5 % tolerance keeps the part inside its operating window; a 3.0 V rail would drop below the minimum at the low end. The 165-FBGA footprint requires a multi-layer PCB with via-in-pad or microvia fan-out for the inner rows. Infineon (formerly Cypress) has marked the CY7C1381D-100BZIT as obsolete. For a BOM that already carries this part, the supply posture is quoted-to-order; for a new design, a pin-compatible alternative from the same or a competing family should be evaluated.","metaTitle":"CY7C1381D-100BZIT 18Mbit SRAM, 100MHz, 165-LBGA, Obsolete","metaDescription":"Infineon CY7C1381D-100BZIT synchronous SRAM, 18Mbit, 512Kx36, 100MHz clock, 8.5ns access, 3.3V, -40°C to 85°C, 165-LBGA.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"title":"CY7C1381D-100BZIT","Package":"Tape & Reel (TR)","Technology":"SRAM - Synchronous, SDR","Access Time":"8.5 ns","Memory Size":"18Mbit","Memory Type":"Volatile","Memory Format":"SRAM","Mounting Type":"Surface Mount","Package / Case":"165-LBGA","Clock Frequency":"100 MHz","lifecycle_stage":"eol_hot","Memory Interface":"Parallel","Voltage - Supply":"3.135V ~ 3.6V","Base Product Number":"CY7C1381","Memory Organization":"512K x 36","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"165-FBGA (13x15)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/4a55a438051b158d7f6fb3b7b5ccb210.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Where can I buy CY7C1381D-100BZIT?","answer":"The part is sourced through independent distribution and surplus inventory.
