It gives two independent ports — each with its own address, data, and control lines — simultaneous access to the same memory array, which is the defining feature for shared-memory designs like multiprocessor mailboxes, FIFO emulation, or video frame buffers where two bus masters need to read and write without arbitration latency. ## 100-TQFP — package and footprint reality The CY7C028-15AC comes in a 100-lead TQFP with a 14x14 mm body. Surface-mount only. No last-time-buy window is open through the authorized channel. Because this is a dual-port SRAM in a specific 100-TQFP footprint with a 5 V supply and 15 ns timing, a drop-in replacement is not trivial. The Cypress CY7C028 family shares the same base pinout across speed grades, but an exact same-function, same-package replacement from another vendor would need to match the 15 ns access time, the 64K x 16 organization, the 5 V supply, and the 100-TQFP footprint — a narrow parametric window. For dual-sourcing or a new-design alternative, the evaluation should start with the 5 V dual-port SRAMs from Renesas (formerly IDT) or Cypress's own higher-density siblings, but every candidate requires a pin-to-pin and timing comparison against the board's specific bus loading.","metaTitle":"CY7C028-15AC Cypress 1Mbit Dual-Port SRAM, 15 ns Access Time","metaDescription":"CY7C028-15AC Cypress 1Mbit (64K x 16) dual-port asynchronous SRAM. 15 ns access time, 4.5V-5.5V, 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, 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":"4.5V ~ 5.5V","Base Product Number":"CY7C028","Memory Organization":"64K x 16","Operating Temperature":"0°C ~ 70°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":"https://cdn.icboms.com/4f2af131776e42e247c31a3362ef7360.pdf","sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/CY7C028-15AC","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/CY7C028-15AC when reusing this data.
