Its dual-port architecture allows two independent systems or processors to read from and write to the same memory array simultaneously, each through its own address, data, and control lines. The 55 ns access time means the part can keep pace with moderate-speed buses without wait states, but it will not match a 10 ns synchronous SRAM in a high-throughput DSP pipeline. Supply range is 4.5V to 5.5V, so it belongs on a 5V rail — not a 3.3V or 1.8V domain. Access time is 55 ns. Write cycle time is 55 ns. The package is a 52-lead PLCC with J-leads, measuring 19.13 x 19.13 mm. J-leads offer better solder-joint fatigue life under thermal cycling than gull-wing leads, which matters for equipment that sees diurnal temperature swings. The part ships in Tray, not tape-and-reel, so plan for pick-and-place handling or manual placement. Cypress (now part of Infineon) no longer manufactures this device. For new designs, evaluate a pin-compatible dual-port SRAM. Expect to work with broker or surplus inventory; verify date codes and condition upon receipt.","metaTitle":"CY7C136A-55JXI SRAM Dual-Port Asynchronous, 55 ns, 16Kbit","metaDescription":"CY7C136A-55JXI is a 16Kbit dual-port asynchronous SRAM with 55 ns access time, 4.5V-5.5V supply, -40°C to 85°C, in 52-PLCC.","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":"55 ns","Memory Size":"16Kbit","Memory Type":"Volatile","Memory Format":"SRAM","Mounting Type":"Surface Mount","Package / Case":"52-LCC (J-Lead)","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Memory Interface":"Parallel","Voltage - Supply":"4.5V ~ 5.5V","Base Product Number":"CY7C136","Memory Organization":"2K x 8","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"52-PLCC (19.13x19.13)","Write Cycle Time - Word, Page":"55ns"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/26ac8dabccf54e936bcb24bb7144afcb.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CY7C136A-55JXI/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between CY7C136A-55JXI and CY7C136A-55JX?","answer":"Both share the same 55 ns access time, 16Kbit density, and 52-PLCC package.
