Housed in a 28-SOJ (300 mil) surface-mount package, this part was designed for cache, scratchpad, or data-buffer roles in legacy 8-bit and 16-bit microcontroller and DSP systems where fast, simple memory expansion was needed without clock management. ## 35 ns access time — bus timing fit The 35 ns access time is the key timing parameter for this asynchronous SRAM. For a legacy 8-bit controller running at 10-12 MHz or a 16-bit DSP with a 20-25 MHz bus, this timing provides adequate margin without wait states. If your system bus runs faster than about 28 MHz, you will need to budget for access-time compatibility — or consider a faster SRAM variant. ## 28-SOJ package — footprint and board fit This is a surface-mount package with J-bend leads on 1.27 mm pitch. The SOJ footprint is distinct from SOIC — the J-lead profile saves board area but requires a specific land pattern. If your existing board uses a 28-pin SOIC or TSOP footprint, a layout change is needed. ## Commercial temperature grade — deployment boundary If your application sees temperature excursions outside 0°C to 70°C — such as outdoor telecom cabinets, factory floors, or under-hood electronics — this part will not meet the thermal specification and an industrial-temperature SRAM should be selected.","metaTitle":"Infineon CY7C185-35SC 64Kbit Asynchronous SRAM, 35 ns","metaDescription":"Infineon CY7C185-35SC 64Kbit (8K x 8) parallel SRAM with 35 ns access time.","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":"35 ns","Memory Size":"64Kbit","Memory Type":"Volatile","Memory Format":"SRAM","Mounting Type":"Surface Mount","Package / Case":"28-BSOJ (0.300\\\", 7.62mm Width)","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-SOJ","Write Cycle Time - Word, Page":"35ns"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/26286f4079bc748514fa0dbdf17e4407.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the access time of the CY7C185-35SC?","answer":"The CY7C185-35SC has a 35 ns access time and a matching 35 ns write cycle time.
