At 15 ns, the part keeps pace with most 8-bit microcontrollers running at 20-25 MHz without wait states, but a faster controller will need to insert cycles or switch to a pipelined memory. Dual-port architecture means two independent devices can read or write to the same memory location simultaneously — useful in shared-memory designs like a dual-processor system or a bridge between a DSP and a host controller. The asynchronous interface eliminates the need for a clock on the memory side, simplifying the PCB layout. ## 68-PLCC package and reflow reality The tape-and-reel packaging suits automated assembly lines. The 68-PLCC footprint is standard — the JEDEC MO-047 outline matches most land patterns, so no custom pad geometry is needed. For a BOM that already uses this part, the 15 ns access time, 5V supply, and 68-PLCC package are the binding constraints for any replacement. A functionally equivalent dual-port SRAM from another vendor (e.g., IDT or Renesas) will likely require a different package or supply voltage — a board spin or socket adapter may be needed. ## Supply voltage and temperature grade Operates from 4.5V to 5.5V, which is the classic 5V logic rail — compatible with legacy 5V microcontrollers, CPLDs, and ASICs. The write cycle time matches the read access time at 15 ns, so the bus turnaround is symmetric — no extra dead cycles needed between read and write operations.","metaTitle":"CY7C144-15JXCT Infineon SRAM, 64Kbit, 15 ns, 68-PLCC","metaDescription":"Infineon CY7C144-15JXCT 64Kbit dual-port asynchronous SRAM, 15 ns access, 5V supply, 68-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":"Tape & Reel (TR)","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":"0°C ~ 70°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/3c8fc66c7400e6b35a2961db05899272.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the direct replacement for CY7C144-15JXCT?","answer":"Infineon does not list an official successor order code for this part.
