That gives an effective data rate of 800 MT/s per pin over a 36-bit-wide bus (512K x 36 organization). The part is volatile, parallel-interface, and optimized for high-throughput cache or buffer applications where a QDR-style part would be overkill but standard sync SRAM leaves bandwidth on the table. Infineon lists the CY7C1170KV18-400BZXC as obsolete. ## Package and temperature — board-fit constraints Surface-mount only. That rules out outdoor telecom cabinets, engine bays, or any environment where the junction sees sustained temperatures above 70°C.","metaTitle":"Infineon CY7C1170KV18-400BZXC 18Mbit DDR II+ SRAM, 400 MHz","metaDescription":"Infineon CY7C1170KV18-400BZXC 18Mbit synchronous DDR II+ SRAM, 512K x 36, 400 MHz clock, 1.7-1.9V, 165-FBGA, 0-70°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"Mfr":"Infineon Technologies","Series":"-","Package":"Tray","Technology":"SRAM - Synchronous, DDR II+","Memory Size":"18Mbit","Memory Type":"Volatile","Memory Format":"SRAM","Mounting Type":"Surface Mount","Package / Case":"165-LBGA","Product Status":"Obsolete","Clock Frequency":"400 MHz","lifecycle_stage":"eol_hot","Memory Interface":"Parallel","Voltage - Supply":"1.7V ~ 1.9V","Base Product Number":"CY7C1170","Memory Organization":"512K x 36","Operating Temperature":"0°C ~ 70°C (TA)","Supplier Device Package":"165-FBGA (13x15)","Write Cycle Time - Word, Page":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/daaa8f3192b0c6ab0ec811070f405e93.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CY7C1170KV18-400BZXC/alternatives.json"},"ai":{"faq":[{"question":"Is CY7C1170KV18-400BZXC obsolete?","answer":"Yes, Infineon has marked the CY7C1170KV18-400BZXC as obsolete.

For a new design, consider a current-generation DDR II+ or QDR SRAM from the same density and speed class, but verify the footprint and timing parameters — the 165-FBGA layout and 400 MHz clock rate are specific to this part. The CY7C1170 base number covers multiple speed and temperature variants; a cross-reference through Infineon's parametric search is the next step."},{"question":"What package does CY7C1170KV18-400BZXC use?","answer":"The CY7C1170KV18-400BZXC is supplied in a 165-ball LBGA (low-profile ball grid array), also described as a 165-FBGA with a 13x15 mm body.
