The 9K (512 x 18) memory array is organized as 512 words by 18 bits, suiting 16- or 18-bit datapaths with parity or ECC overhead. ## Key features for the design-in decision Retransmit capability allows reading the same data multiple times, useful for packet retry or debug. Programmable flags (almost-full, almost-empty) are supported, giving the host controller early warning before overflow or underflow. Expansion in both depth and width is supported, so multiple devices can cascade for larger buffers without external logic. The part is unidirectional, meaning data flows in one direction only — not a bidirectional dual-port. Maximum supply current is 50 mA. The 64-LQFP package (also specified as 64-TQFP, 14x14 mm body) is a common surface-mount footprint with 0.8 mm pitch.","metaTitle":"CY7C4215-15AXI Synchronous FIFO, 66.7 MHz, 10 ns, 9K","metaDescription":"Infineon (Cypress) CY7C4215-15AXI synchronous FIFO, 66.7 MHz, 10 ns access, 9K (512x18), 64-LQFP, -40 to 85°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":"CY7C","Package":"Tube","Function":"Synchronous","Data Rate":"66.7MHz","Access Time":"10ns","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":"4.5 V ~ 5.5 V","Base Product Number":"7C4215","Operating Temperature":"-40°C~85°C","Retransmit Capability":"Yes","Current - Supply (Max)":"50mA","Supplier Device Package":"64-TQFP (14x14)","Programmable Flags Support":"Yes"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/1856114dd8a777112a8d90d2bbbb7108.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the replacement for CY7C4215-15AXI?","answer":"A pin-compatible drop-in from the same CY7C family may exist, but without a manufacturer-issued cross-reference, any substitute must be verified against the original footprint and timing.
