It provides two independent ports with separate address, data, and control lines, allowing simultaneous read/write access from two bus masters or processors. ## 6.5 ns access time — timing margin for the shared bus The 6.5 ns access time at 100 MHz clock gives the designer a 10 ns cycle window. The dual-port architecture eliminates the arbitration overhead of multiplexed single-port SRAM, but the 6.5 ns output-enable-to-data-valid window still needs to clear the setup time of the receiving FPGA or ASIC. With a 100 MHz bus, the timing budget after trace delay and clock skew runs tight — the 6.5 ns figure is the headline number, but the real margin depends on the output hold time and the load capacitance on the data lines. ## Obsolete — no direct Infineon replacement on record Infineon has not published a direct pin-compatible successor for this specific dual-port synchronous SRAM. The 100-TQFP footprint and 3.3 V supply rail are common enough that a cross-ship against a known-good date code lot is the practical path — there is no drop-in replacement from the same manufacturer. ## 100-TQFP (14x14) — footprint and storage The 100-TQFP (14x14) package is a standard fine-pitch quad flat pack. The Tray shipping medium means the parts arrive in antistatic trays, not tape-and-reel. For the storeroom, these trays stack neatly but take up more shelf space per unit than a reel. Store the trays dry with desiccant and a humidity indicator card. It will not survive an unheated enclosure, engine bay, or outdoor cabinet without a heater.","metaTitle":"CY7C09099V-6AXC Dual-Port SRAM, 1Mbit, 6.5 ns, 100 MHz","metaDescription":"Infineon CY7C09099V-6AXC 1Mbit synchronous dual-port SRAM, 6.5 ns access time, 100 MHz clock, 128K x 8, 100-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":"6.5 ns","Memory Size":"1Mbit","Memory Type":"Volatile","Memory Format":"SRAM","Mounting Type":"Surface Mount","Package / Case":"100-LQFP","Product Status":"Obsolete","Clock Frequency":"100 MHz","lifecycle_stage":"eol_hot","Memory Interface":"Parallel","Voltage - Supply":"3V ~ 3.6V","Base Product Number":"CY7C09099","Memory Organization":"128K x 8","Operating Temperature":"0°C ~ 70°C (TA)","Supplier Device Package":"100-TQFP (14x14)","Write Cycle Time - Word, Page":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/e43ffc67b59981903ef2b49ae3590f6b.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is CY7C09099V-6AXC obsolete?","answer":"Yes, the CY7C09099V-6AXC is officially Obsolete per Infineon's lifecycle status.
