Its 8 ns access time means the data appears on the bus within 8 ns of the address being valid — fast enough to interface with a 100 MHz-class processor without wait states, assuming typical board delays. The parallel interface is straightforward to hook up to any MCU or FPGA with a memory controller, no configuration needed. ## Package and footprint — 44-TSOP II The device comes in a 44-TSOP II package, a standard surface-mount footprint measuring 10.16 mm body width. It ships in a tray. The mounting type is Surface Mount. For a layout engineer, the 44-TSOP II is a common pinout for 256K x 16 asynchronous SRAMs, so a board designed for this part can often accept a drop-in alternate from another vendor — but always check the pin 1 orientation and any NC pins against the target alternate's datasheet.","metaTitle":"Cypress CY7C1041CV33-8ZSXI 4Mbit Async SRAM, 8 ns","metaDescription":"Cypress CY7C1041CV33-8ZSXI 4Mbit (256Kx16) asynchronous SRAM with 8 ns access time, 3.3V supply, -40°C to 85°C.","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":"8 ns","Memory Size":"4Mbit","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":"CY7C1041","Memory Organization":"256K x 16","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"44-TSOP II","Write Cycle Time - Word, Page":"8ns"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.0806","priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CY7C1041CV33-8ZSXI/alternatives.json"},"ai":{"faq":[{"question":"Is CY7C1041CV33-8ZSXI obsolete?","answer":"Yes, the CY7C1041CV33-8ZSXI is listed as Obsolete.

It must be sourced through the surplus and broker market."},{"question":"What is the replacement for CY7C1041CV33-8ZSXI?","answer":"Cypress has not published a direct successor. For new designs, look for a current-production 4Mbit (256K x 16) asynchronous SRAM in a 44-TSOP II package with 8 ns access time and 3.3V supply. Candidates include the ISSI IS61WV25616BLL-8TLI or the Alliance AS7C34098A-10TIN, but you must verify pin compatibility and timing from the respective datasheets."},{"question":"What is the access time of CY7C1041CV33-8ZSXI?","answer":"The access time is 8 ns.
