For a system running a 33 MHz or 40 MHz bus clock (30 ns or 25 ns period), this leaves 10 ns to 15 ns of setup margin before the next clock edge — comfortable for most glue-logic interfaces. If your legacy design was originally specified for a 12 ns or 10 ns part, this 15 ns variant may not meet timing closure; verify the address-to-clock setup window in your worst-case temperature and voltage corner. If you are qualifying this for a new design, look for a pin-compatible 1 Mbit asynchronous SRAM in 44-TSOP II from a current-production family (e.g., the Alliance Memory or ISSI equivalents that share the same footprint and 3.3 V supply). ## Package and footprint — the mechanical constraint Any replacement must match this footprint — pin 1 location, pitch, and body dimensions — to avoid a board respin. The shipping medium is listed as Bag, which is typical for tray or tube quantities; this does not affect the device package itself.","metaTitle":"CY7C1021CV33-15ZXC SRAM, 1 Mbit, 15 ns, 44-TSOP II, Obsolete","metaDescription":"Infineon (Cypress) CY7C1021CV33-15ZXC asynchronous SRAM, 64K x 16, 15 ns access, 3V–3.6V, 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":"Bag","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":"0°C ~ 70°C (TA)","Supplier Device Package":"44-TSOP II","Write Cycle Time - Word, Page":"15ns"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.8600","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/b8de780a0263d3c8d238b651a92bb2a7.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CY7C1021CV33-15ZXC/alternatives.json"},"ai":{"faq":[{"question":"Is CY7C1021CV33-15ZXC obsolete?","answer":"Yes, the manufacturer has marked this part as Obsolete.
