It will not operate from a 3.3V rail. If your system runs on 3.3V logic, you need a different memory — the CY7C1020BN family has no 3.3V variant; look instead at the CY7C1021DV33 or similar 3.3V asynchronous SRAMs in the same 44-TSOP footprint. ## Obsolete — sourcing strategy matters This part carries an official obsolete product status. Infineon (formerly Cypress) has ended production; there is no last-time-buy window still open. Date-code provenance and device authenticity become the buyer's primary concern — verify the parts come from a traceable source, and budget for possible incoming inspection. If the application sees temperature extremes, a different memory tier is required.","metaTitle":"CY7C1020BN-12ZXC SRAM, 512Kbit, 12 ns, 44-TSOP, Obsolete","metaDescription":"Infineon CY7C1020BN-12ZXC asynchronous SRAM, 512Kbit (32K x 16), 12 ns access time, 4.5V-5.5V supply, 0°C-70°C, 44-TSOP II.","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":"Tray","Technology":"SRAM - Asynchronous","Access Time":"12 ns","Memory Size":"512Kbit","Memory Type":"Volatile","Memory Format":"SRAM","Mounting Type":"Surface Mount","Package / Case":"44-TSOP (0.400\\\", 10.16mm Width)","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Memory Interface":"Parallel","Voltage - Supply":"4.5V ~ 5.5V","Base Product Number":"CY7C1020","Memory Organization":"32K x 16","Operating Temperature":"0°C~70°C(TA)","Supplier Device Package":"44-TSOP II","Write Cycle Time - Word, Page":"12ns"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/c4b9e7be46f49f583bf4acf2ba6db74e.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is CY7C1020BN-12ZXC obsolete?","answer":"Yes, the official product status is Obsolete.
