Two independent ports with separate address, data, and control lines allow simultaneous read/write access from two bus masters — a common architecture for shared memory in multiprocessor systems, FIFO emulation, or mailbox registers. The 20 ns access time sets the arbitration window: when both ports hit the same address, the on-chip logic resolves contention without external logic. A 20 ns access time means the SRAM can complete a read or write cycle in 20 ns, supporting bus clocks up to roughly 50 MHz with zero wait states. For a dual-port part, the access time directly affects the arbitration latency: the busier the shared memory, the tighter the timing budget. This part is sized for moderate-speed embedded systems — think DSP + microcontroller sharing a lookup table or data buffer — not for a 200 MHz cache line. ## 3V–3.6V supply and commercial temperature range Not rated for under-hood automotive, outdoor telecom cabinets, or extended-temperature industrial floors. Infineon (formerly Cypress Semiconductor) lists the CY7C027V-20AC as obsolete. No factory orders or last-time-buy windows remain open. Buyers should confirm date code and condition at quote time; this is a mature part with no active factory support.","metaTitle":"Infineon CY7C027V-20AC 512Kbit Dual-Port SRAM, 20 ns","metaDescription":"Infineon CY7C027V-20AC 512Kbit (32K x 16) asynchronous dual-port SRAM, 20 ns access, 3V–3.6V, 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":"20 ns","Memory Size":"512Kbit","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":"CY7C027","Memory Organization":"32K x 16","Operating Temperature":"0°C~70°C(TA)","Supplier Device Package":"100-TQFP (14x14)","Write Cycle Time - Word, Page":"20ns"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null},"ai":{"faq":[{"question":"Is CY7C027V-20AC obsolete?","answer":"Yes, Infineon lists the CY7C027V-20AC as obsolete.
