If you're retrofitting a board that originally used a 5V SRAM, this is the right voltage domain. Do not run it at 3.3V — the minimum is 4.5V. ## Obsolete — plan your sourcing accordingly If you have a production run that depends on this SRAM, consider qualifying a pin-compatible alternative now to avoid a future supply gap.","metaTitle":"CY7C199-35VC SRAM, 256Kbit, 35 ns, 5V, SOJ-28","metaDescription":"Infineon (Cypress) CY7C199-35VC asynchronous SRAM, 256Kbit (32K x 8), 35 ns access time, 4.5V-5.5V supply, 0°C-70°C, SOJ-28.","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":"256Kbit","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":"CY7C199","Memory Organization":"32K 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":"$0.9600","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/db4c3dbfc281eb6c685e985fa829ece5.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Will CY7C199-35VC work with a 5V supply?","answer":"Yes.
