This is a volatile memory — data is retained only while power is applied. Infineon lists the CY7C1021CV33-8ZXCT as obsolete. ## 8 ns access time — timing closure for the bus The 8 ns access time is the headline speed spec for this asynchronous SRAM. It defines how quickly data appears on the outputs after the address is valid. In a system with a 100 MHz bus, the 8 ns window leaves about 2 ns of margin after accounting for clock-to-output delay and PCB trace skew — tight but workable with careful signal-integrity design. If your controller's address-to-data setup requirement is looser than 8 ns, this part fits without wait states. ## 64K x 16 organization — 16-bit data bus The 64K x 16 organization means the part presents a 16-bit-wide data bus. For a 32-bit microcontroller, two of these SRAMs can be paired to form a 32-bit memory word. The 1Mbit total density suits moderate buffer or scratchpad applications — think Ethernet frame buffers, audio sample storage, or configuration tables in industrial controllers.","metaTitle":"CY7C1021CV33-8ZXCT Infineon 1Mbit Async SRAM, 8 ns, 44-TSOP","metaDescription":"CY7C1021CV33-8ZXCT is an obsolete 1Mbit (64K x 16) asynchronous SRAM with 8 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":"Tape & Reel (TR)","Technology":"SRAM - Asynchronous","Access Time":"8 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":"8ns"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/cb9e43c6aaaaaca4c2680a604607fb10.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is CY7C1021CV33-8ZXCT obsolete and what are my options?","answer":"Yes, Infineon lists the CY7C1021CV33-8ZXCT as obsolete. There is no official replacement part number from Infineon. For existing designs, the part can be sourced through independent distribution. For new designs, consider the pin-compatible CY7C1021DV33 family, which uses the same 44-TSOP II footprint — verify supply voltage and timing compatibility with your system."},{"question":"What is the equivalent replacement for CY7C1021CV33-8ZXCT?","answer":"There is no direct Infineon replacement listed. The CY7C1021DV33 family is pin-compatible and shares the same 44-TSOP II package, but you must check the supply voltage range and access time against your design. Other 1Mbit asynchronous SRAMs in 44-TSOP from vendors like ISSI or Alliance Memory may also be footprint-compatible — verify the pinout against your PCB layout."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/CY7C1021CV33-8ZXCT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/CY7C1021CV33-8ZXCT when reusing this data.
