It uses a parallel interface and delivers a 15 ns access time, making it suitable for cache, buffer, or scratchpad memory in embedded systems that need fast, simple read/write cycles without a clock. ## 15 ns access time — timing margin in the bus For a processor running at 33 MHz (30 ns cycle), this leaves about half a cycle for address decode, propagation, and setup — tight but workable with a fast memory controller. If your bus has additional buffering or a slow FPGA bridge, you may need to budget an extra wait state. ## 64K x 16 organization — word-wide or byte-wide access The 16-bit data bus lets a 16-bit or 32-bit microcontroller fetch a 16-bit operand in one cycle. For 8-bit buses, you can use the upper or lower byte enables (noted in the datasheet) to access individual bytes. The 1 Mbit density fills a 64K address space at 16-bit width — common for boot code shadowing or display frame buffers in mid-range embedded designs. ## Package and footprint — 44-TSOP II The part comes in a 44-TSOP II (0.400\" body width, 10.16 mm wide) surface-mount package. The shipping medium is Tray, not tape-and-reel, so factor that into your pick-and-place setup. ## Obsolete — sourcing reality and the replacement path The CY7C1021BNV33L-15ZXI is marked Obsolete by the manufacturer. If you are qualifying a replacement, look for a pin-compatible 44-TSOP II async SRAM with the same 64K x 16 organization and 15 ns access time from vendors like ISSI (IS61LV6416-15TLI) or Alliance (AS7C34096-15TIN) — but verify the pinout and timing against your design, as the evidence does not list an official cross-reference.","metaTitle":"CY7C1021BNV33L-15ZXI Infineon 1Mbit Async SRAM, 15 ns","metaDescription":"Infineon CY7C1021BNV33L-15ZXI 1Mbit asynchronous SRAM, 64K x 16, 15 ns access, 3V-3.6V, -40°C to 85°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":"15 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":"-40°C~85°C(TA)","Supplier Device Package":"44-TSOP II","Write Cycle Time - Word, Page":"15ns"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$58.2500","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/b52313df5d733a20a081352c1eb65721.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CY7C1021BNV33L-15ZXI/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement or equivalent for CY7C1021BNV33L-15ZXI?","answer":"No official replacement order code is listed.
