The 10 ns access and write cycle time means the part can keep up with a 100 MHz bus without wait states, provided the controller's address-to-data setup is met. ## Package and temperature grade — what fits where This limits the part to indoor, office, or controlled-environment equipment such as telecom racks, test gear, and embedded controllers — not for under-hood automotive, outdoor base stations, or industrial motor drives where -40°C to +85°C or wider is required. This part is marked as obsolete by the manufacturer. For BOM lines that require this exact 64K x 16, 10 ns, 3.3V asynchronous SRAM in 44-TSOP II, the procurement path is through independent distribution or surplus inventory. A buyer should verify date-code consistency and marking authenticity when sourcing from the secondary market, as the part is no longer in factory production.","metaTitle":"CY7C1021BNV33L-10ZXCT Infineon SRAM, 1Mbit 10 ns 44-TSOP II","metaDescription":"Infineon CY7C1021BNV33L-10ZXCT 1Mbit asynchronous SRAM, 10 ns access, 3V–3.6V supply, 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":"Tape & Reel (TR)","Technology":"SRAM - Asynchronous","Access Time":"10 ns","Memory Size":"1Mbit","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":"3V ~ 3.6V","Base Product Number":"CY7C1021","Memory Organization":"64K x 16","Operating Temperature":"0°C ~ 70°C (TA)","Supplier Device Package":"44-TSOP II","Write Cycle Time - Word, Page":"10ns"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/10330d3e23287666913c318fd4ab1a47.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the replacement for CY7C1021BNV33L-10ZXCT?","answer":"A functionally equivalent 64K x 16, 10 ns, 3.3V asynchronous SRAM in 44-TSOP II from another brand (e.g., ISSI, Alliance Memory) may be pin-compatible, but compatibility must be verified against the specific datasheet and board footprint.
