The parallel interface and standard 44-TSOP II footprint match legacy designs in telecom line cards, industrial controllers, and test equipment where the board was laid out for this package generation. At 100 MHz bus speeds, a 10 ns window is tight — you need to verify the address-to-data valid path against the controller's tACC requirement. Cypress (now part of Infineon) has discontinued production; there is no listed official successor in the record. For BOM lines that still specify this exact order code, the only channel is surplus or broker stock. It is suitable for office equipment, lab instruments, and controlled indoor environments. ## 44-TSOP II footprint — board-level fit The 44-TSOP II package (0.400 inch body width, 10.16 mm) is a standard SRAM footprint that has been used across multiple vendors for two decades. If your PCB was laid out for a 44-pin TSOP II async SRAM, this part drops in without a board spin. The surface-mount profile is compatible with standard reflow processes;.","metaTitle":"CY7C1021CV33-10ZXC Cypress 1Mbit Async SRAM, 10 ns","metaDescription":"Cypress CY7C1021CV33-10ZXC 1Mbit (64K x 16) asynchronous SRAM, 10 ns access time, 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":"Bag","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":"$1.7400","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/b8de780a0263d3c8d238b651a92bb2a7.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CY7C1021CV33-10ZXC/alternatives.json"},"ai":{"faq":[{"question":"Is CY7C1021CV33-10ZXC still available or obsolete?","answer":"This part is obsolete per the lifecycle record.
