Dual-port architecture allows two independent systems to read from or write to the same memory array simultaneously. ## 15 ns access time — timing budget fit For a 5 V system running at 33 MHz or slower, this gives roughly one clock cycle for address-to-data valid, with margin for PCB trace delay and output loading. If your design currently uses a 12 ns or 10 ns dual-port SRAM, the 15 ns part may require a wait state insertion or a slower clock — check the setup/hold timing against your controller's memory controller. The 8K x 8 organization means the address bus is 13 bits wide; the dual-port nature doubles the control signals (two chip enables, two output enables, two write enables), so the 64-TQFP pinout is fully utilised.","metaTitle":"Infineon CY7C144E-15AXCT SRAM Dual Port, 64Kbit, 15 ns","metaDescription":"CY7C144E-15AXCT is an Infineon (Cypress) 64Kbit dual-port asynchronous SRAM, 15 ns access time, 64-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":"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":"64-LQFP","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":"64-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/0c592dfbc5160a28d9f87bcc6698f161.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is a direct replacement for CY7C144E-15AXCT?","answer":"No official direct replacement is recorded in the available lifecycle data.
