The 45 ns access time sets the read-cycle ceiling for the parallel bus — the processor must insert wait states if its bus clock period is shorter than the sum of access time, setup, and hold. The Tape & Reel variant (TR) is the standard pick-and-place feed; the Cut Tape (CT) option supports prototype or low-volume builds without committing to a full reel. ## Supply voltage and temperature grade Write cycle time matches the read access at 45 ns (word, page mode), so the bus timing is symmetrical — no extra wait states on writes versus reads. The parallel interface is straightforward: address, data, chip enable, output enable, and write enable lines connect directly to the host controller.","metaTitle":"CY62146ESL-45ZSXIT Infineon MoBL SRAM, 4 Mbit, 45 ns","metaDescription":"Infineon CY62146ESL-45ZSXIT MoBL asynchronous SRAM, 4 Mbit (256K x 16), 45 ns access, 2.2-5.5 V supply, -40 to 85 °C, 44-TSOP II.","metaKeywords":null},"attributes":{"series":"MoBL®","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Series":"MoBL®","Package":"Tape & Reel (TR); Cut Tape (CT)","Technology":"SRAM - Asynchronous","Access Time":"45 ns","Memory Size":"4Mbit","Memory Type":"Volatile","Memory Format":"SRAM","Mounting Type":"Surface Mount","Package / Case":"44-TSOP (0.400\\\", 10.16mm Width)","lifecycle_stage":"eol_hot","Memory Interface":"Parallel","Voltage - Supply":"2.2V ~ 3.6V, 4.5V ~ 5.5V","Memory Organization":"256K x 16","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"44-TSOP II","Write Cycle Time - Word, Page":"45ns"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$7.84","stockQuantity":23,"priceTiers":[{"qty":1,"price":"$7.84000","currency":"USD"},{"qty":10,"price":"$7.21100","currency":"USD"},{"qty":25,"price":"$7.06080","currency":"USD"},{"qty":50,"price":"$7.03640","currency":"USD"},{"qty":100,"price":"$6.31360","currency":"USD"},{"qty":250,"price":"$6.12280","currency":"USD"},{"qty":500,"price":"$5.82232","currency":"USD"},{"qty":1000,"price":"$5.61932","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/2ba7942d7e40c5b0c57ef049a4fcc47b.pdf","sourceUrl":null},"ai":{"faq":[{"question":"How do I get current pricing and availability for CY62146ESL-45ZSXIT?","answer":"Submit an RFQ through this listing."},{"question":"What is the closest functional second-source for CY62146ESL-45ZSXIT?","answer":"The CY7C1041GN30-10ZSXIT is a functional peer: same 4 Mbit density, 256K x 16 organization, 44-TSOP II package, and 2.2 V supply.
