The only supply channel is independent distribution — surplus, new-old-stock, or broker-sourced lots. This is a Cypress synchronous dual-port SRAM organised as 4K x 18 bits. The 12 ns access time and 50 MHz clock rate let two independent bus masters — two processors, a processor and an FPGA, or a processor and a DMA controller — read and write the same memory array without dead cycles. The 18-bit word width suits designs that carry a parity bit per byte or a ninth tag bit alongside the 16-bit data. Supplied in a 100-pin TQFP (14x14 mm body) for surface-mount assembly. Supply voltage range is 3.0 V to 3.6 V, compatible with 3.3 V nominal rails.","metaTitle":"CY7C09349AV-12AC Cypress 72Kbit Dual-Port SRAM, 12 ns","metaDescription":"CY7C09349AV-12AC is an obsolete Cypress 72Kbit synchronous dual-port SRAM with 12 ns access time, 50 MHz clock, 4K x 18 organization.","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":"12 ns","Memory Size":"72Kbit","Memory Type":"Volatile","Memory Format":"SRAM","Mounting Type":"Surface Mount","Package / Case":"100-LQFP","Product Status":"Obsolete","Clock Frequency":"50 MHz","lifecycle_stage":"eol_hot","Memory Interface":"Parallel","Voltage - Supply":"3V ~ 3.6V","Base Product Number":"CY7C09349","Memory Organization":"4K x 18","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,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/fb8efd98bc3a30edb28206d554f0c366.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CY7C09349AV-12AC/alternatives.json"},"ai":{"faq":[{"question":"What is the access time of CY7C09349AV-12AC?","answer":"The access time is 12 ns, with a maximum clock frequency of 50 MHz. This defines the window for valid data on the bus after the address is presented; a 12 ns part is the slower speed grade in the CY7C09349AV family, where a 10 ns variant also exists."},{"question":"Is CY7C09349AV-12AC pin compatible with CY7C09349AV-10AC?","answer":"Yes, the -12AC and -10AC are the same base part number (CY7C09349AV) differing only in speed grade. Both use the same 100-TQFP package and pinout. The -10AC is faster (10 ns access) but otherwise identical in function, supply, and footprint."},{"question":"What package does CY7C09349AV-12AC have?","answer":"The package is a 100-pin TQFP (14x14 mm body), surface-mount.
