It is designed for systems that need two independent ports with full simultaneous read/write access to the same memory array — common in multi-processor shared memory, baseband packet buffers, and video frame stores where one port handles the data path and the other the control processor. The 5 ns access time and 100 MHz clock frequency set the timing budget. The 36-bit word width is wider than the common 8/16/32-bit SRAMs; it directly connects to a 36-bit DSP or a 32-bit CPU with parity bits, saving external muxing. The 16K depth is moderate — enough for a 64 KB L2 cache tag or a 72 KB packet buffer in a 10/100 Ethernet design. That confines it to indoor, conditioned environments — server rooms, lab equipment, office networking gear. No industrial or automotive use without qualification data. The CY7C09569V-100AC carries an official lifecycle status of Obsolete. Cypress (now Infineon) has discontinued production; there is no last-time-buy window open. The only available units are new-old-stock or surplus inventory held by independent distributors. Because this part is obsolete, a buyer filling a BOM line for a legacy board should verify date code freshness and request a counterfeit-inspection certificate from the supplier. ## Package and footprint — 144-TQFP","metaTitle":"CY7C09569V-100AC Cypress 576Kbit Dual-Port SRAM, 5 ns","metaDescription":"Cypress CY7C09569V-100AC 576Kbit dual-port synchronous SRAM, 16K x 36, 5 ns access time, 100 MHz clock, 3V–3.6V, 144-TQFP.","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 - Dual Port, Synchronous","Access Time":"5 ns","Memory Size":"576Kbit","Memory Type":"Volatile","Memory Format":"SRAM","Mounting Type":"Surface Mount","Package / Case":"144-LQFP","Product Status":"Obsolete","Clock Frequency":"100 MHz","lifecycle_stage":"eol_hot","Memory Interface":"Parallel","Voltage - Supply":"3V ~ 3.6V","Base Product Number":"CY7C09569","Memory Organization":"16K x 36","Operating Temperature":"0°C~70°C(TA)","Supplier Device Package":"144-TQFP (20x20)","Write Cycle Time - Word, Page":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/6a280ff03ee762b399f3c4379ba549a6.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is CY7C09569V-100AC obsolete or end of life?","answer":"Yes, the CY7C09569V-100AC is officially Obsolete.
