The dual-port architecture gives two independent ports with separate address, data, and control lines, so two bus masters can read or write the same memory array without external arbitration logic — useful for shared buffers, mailbox registers, or video line stores where one port is the writer and the other the reader. ## Industrial temperature and supply — the operating envelope The supply range of 3V to 3.6V lets it run from a 3.3V rail with margin for ripple and load transients. The 15 ns write cycle time (word and page modes) matches the read access, so back-to-back operations at the same port don't create a throughput bottleneck. The only supply channel is independent distribution — surplus stock, new-old-stock, or pulled inventory. If this is a production BOM line, the buyer needs to qualify the part against an RFQ for whatever stock remains in the channel, and start planning a pin-compatible or functionally equivalent migration. ## 100-TQFP — footprint and rework realities The 100-TQFP (14x14 mm) package is a 0.5 mm pitch fine-pitch surface-mount part. The exposed pad is not present on this package variant, so all thermal dissipation goes through the leads. The footprint is standard for 100-pin TQFP, but any replacement candidate must match the same pad layout to avoid a board respin.","metaTitle":"Cypress CY7C028V-15AXIT 1Mbit Dual-Port SRAM, 15 ns","metaDescription":"Cypress CY7C028V-15AXIT 1Mbit dual-port asynchronous SRAM, 64K x 16, 15 ns access, 3V-3.6V, -40°C to 85°C industrial, 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":"Tape & Reel (TR)","Technology":"SRAM - Dual Port, Asynchronous","Access Time":"15 ns","Memory Size":"1Mbit","Memory Type":"Volatile","Memory Format":"SRAM","Mounting Type":"Surface Mount","Package / Case":"100-LQFP","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Memory Interface":"Parallel","Voltage - Supply":"3V ~ 3.6V","Base Product Number":"CY7C028","Memory Organization":"64K x 16","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"100-TQFP (14x14)","Write Cycle Time - Word, Page":"15ns"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null},"ai":{"faq":[{"question":"What is the replacement for CY7C028V-15AXIT?","answer":"A functionally equivalent dual-port SRAM with the same 1 Mbit density, 64K x 16 organization, and 15 ns access time in a 100-pin TQFP package would be the closest match, but pin compatibility must be verified against the target footprint."},{"question":"Is CY7C028V-15AXIT RoHS compliant?","answer":"The suffix 'IT' in the order code typically indicates RoHS-compliant and lead-free finish for Cypress parts, but the available record does not carry an explicit RoHS compliance statement.
