The dual-port architecture gives each port its own address, data, and control lines, so a processor and a DMA controller — or two processors — can read or write the same location concurrently, with on-chip arbitration handling collisions. ## 15 ns access — bus timing margin For a processor running at 33 MHz (30 ns cycle), this part leaves about 15 ns of bus timing margin after address decode and setup — comfortable for a glue-logic interface without a fast-page or pipelined memory controller. If your system clock is faster than 40 MHz, you will need to add wait states or look at a 12 ns or 10 ns dual-port SRAM. ## Industrial temperature and 5 V supply If your new design has moved to 3.3 V or 1.8 V core logic, this SRAM will need a level translator or a separate 5 V rail. ## 68-PLCC package — hand-solderable and rework-friendly The 68-lead PLCC with J-leads (24.23 mm square body) is a surface-mount package that can still be hand-soldered with a fine-tip iron or hot-air rework station. The J-lead form gives a visual solder-joint inspection and is easier to desolder than a QFP. The PLCC socket is also available for prototyping or field-replacement scenarios. No exposed thermal pad — the package relies on the leads for heat conduction, so keep air flow across the part if dissipation is significant. No last-time-buy window is open from the factory.","metaTitle":"CY7C144-15JXI 64Kbit Dual-Port SRAM, 15 ns, Industrial Temp","metaDescription":"Infineon CY7C144-15JXI 64Kbit (8K x 8) dual-port asynchronous SRAM in 68-PLCC. 15 ns access time, 4.5V-5.5V supply, -40°C 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":"-","Package":"Tube","Technology":"SRAM - Dual Port, Asynchronous","Access Time":"15 ns","Memory Size":"64Kbit","Memory Type":"Volatile","Memory Format":"SRAM","Mounting Type":"Surface Mount","Package / Case":"68-LCC (J-Lead)","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Memory Interface":"Parallel","Voltage - Supply":"4.5V ~ 5.5V","Base Product Number":"CY7C144","Memory Organization":"8K x 8","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"68-PLCC (24.23x24.23)","Write Cycle Time - Word, Page":"15ns"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/2f91f8498932cd41216b0f439ddb9355.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is CY7C144-15JXI obsolete?","answer":"Yes, Infineon has marked the CY7C144-15JXI as obsolete.

For new designs, consider an active dual-port SRAM from Infineon's CY7C14xxx family or Renesas's 7000 series with similar density (64Kbit) and speed (15 ns or faster) in a PLCC or TQFP package.
