A 20 ns access time means the SRAM can complete a read cycle within 20 ns of the address being valid. This speed grade suits legacy 8-bit microcontrollers and DSPs with bus cycles in the 30–50 ns range, providing adequate setup margin. At 5V ±10% the part delivers consistent timing; derating at lower supply voltages is minimal for this family. ## Obsolete — sourcing for production and repair For new designs, a pin-compatible 64Kbit asynchronous SRAM in a 28-pin DIP from another manufacturer should be evaluated.","metaTitle":"CY7C185-20PC Cypress 64Kbit Asynchronous SRAM, 20 ns, DIP-28","metaDescription":"CY7C185-20PC is a 64Kbit (8K x 8) asynchronous SRAM with 20 ns access time in a 28-pin PDIP package.","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 - Asynchronous","Access Time":"20 ns","Memory Size":"64Kbit","Memory Type":"Volatile","Memory Format":"SRAM","Mounting Type":"Through Hole","Package / Case":"28-DIP (0.300\\\", 7.62mm)","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Memory Interface":"Parallel","Voltage - Supply":"4.5V ~ 5.5V","Base Product Number":"CY7C185","Memory Organization":"8K x 8","Operating Temperature":"0°C~70°C(TA)","Supplier Device Package":"28-PDIP","Write Cycle Time - Word, Page":"20ns"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/2e9f629d27aafee27bd038464819317e.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CY7C185-20PC/alternatives.json"},"ai":{"faq":[{"question":"Is CY7C185-20PC obsolete?","answer":"Yes, Cypress has listed the CY7C185-20PC as Obsolete.
