The part supports depth and width expansion, includes programmable flags and retransmit capability, and is housed in a 64-LQFP (64-TQFP 10x10) package for surface-mount assembly. The CY7C4215V-15ASC is officially obsolete per Cypress's product lifecycle. There is no listed direct replacement or cross-reference from the manufacturer. In a synchronous system clocked at 66.7 MHz (15 ns period), the 11 ns access leaves about 4 ns of setup margin before the next clock edge — tight but workable if the board's trace delays and clock skew are controlled. If your legacy design used a faster FIFO (e.g., 8 ns access), this part may not meet the read-cycle timing without adding a wait state. ## 512 x 18 organization and retransmit The 18-bit word width matches common 16-bit data buses with two parity bits, or 18-bit parallel interfaces on DSPs and network processors. Retransmit capability lets the FIFO reread data from the beginning without a full reset — useful in protocol buffers where a dropped packet needs retransmission. Depth expansion allows cascading multiple devices for larger buffers, while width expansion handles wider data paths.","metaTitle":"CY7C4215V-15ASC Synchronous FIFO, 66.7 MHz, 11 ns Access","metaDescription":"Cypress CY7C4215V-15ASC synchronous FIFO, 9K (512x18), 66.7 MHz data rate, 11 ns access time.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"Mfr":"Infineon Technologies","Series":"CY7C","Package":"Bag","Function":"Synchronous","Data Rate":"66.7MHz","Access Time":"11ns","Memory Size":"9K (512 x 18)","FWFT Support":"No","Mounting Type":"Surface Mount","Expansion Type":"Depth, Width","Package / Case":"64-LQFP","Product Status":"Obsolete","Bus Directional":"Uni-Directional","lifecycle_stage":"eol_hot","Voltage - Supply":"3 V ~ 3.6 V","Base Product Number":"7C4215","Operating Temperature":"0°C ~ 70°C","Retransmit Capability":"Yes","Current - Supply (Max)":"30mA","Supplier Device Package":"64-TQFP (10x10)","Programmable Flags Support":"Yes"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/8e2abdbdcd8858b4cc84fc9e7db99fb6.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is CY7C4215V-15ASC obsolete?","answer":"Yes, the CY7C4215V-15ASC is obsolete. Cypress has discontinued production, and there is no manufacturer-recommended direct replacement or cross-reference.

A functionally similar synchronous FIFO with the same 512 x 18 organization and 3.3 V supply would need to be evaluated for pin-compatibility and timing.
