It operates from a 3 V to 3.6 V supply and is rated for -40°C to 125°C. ## 15 ns access time — what it means for the bus The 15 ns access time sets the window for the memory controller to latch valid data after asserting the address. The write cycle time matches at 15 ns. ## Obsolete — sourcing reality Infineon lists the CY7C1049CV33-15ZSXE as obsolete. No official successor is published in the lifecycle record. For a BOM line that needs this exact footprint and timing, the supply path is through surplus and independent distribution. We source and quote this part to order against an RFQ; availability and current pricing are confirmed at quote time.","metaTitle":"Infineon CY7C1049CV33-15ZSXE SRAM, 4Mbit, 15ns, 44-TSOP II","metaDescription":"CY7C1049CV33-15ZSXE is an obsolete 4Mbit asynchronous SRAM with 15ns access time, 3V-3.6V supply, -40°C to 125°C range.
