Typical applications include industrial motor drives, telecom line cards, test equipment, and any system where deterministic read/write latency matters more than density. For a 50 MHz bus (20 ns period), that leaves 10 ns of setup/hold margin before the next clock edge — enough to avoid wait states in most glue-logic designs. If your host bus runs faster than 66 MHz, you will need to budget the access time against the controller's output-hold spec; at 50 MHz and below this part keeps the timing clean. ## 5V supply — legacy system fit No level shifters are needed on the address/data bus when connecting to a 5V host. If your new design has migrated to 3.3V, the sibling CY7C1041GE30-10ZSXI runs from a 3.0V supply and is otherwise pin-compatible. Housed in a 44-TSOP II (10.16 mm body width), this is a surface-mount package with a 0.8 mm pin pitch. The footprint is standard across the 4 Mbit async SRAM family — the same board layout works for the 3.3V variant and the tape-and-reel version (CY7C1041G-10ZSXIT). The tray shipment (25 pieces per tray) is typical for engineering samples and low-volume production; for higher volumes the tape-and-reel option avoids manual placement.","metaTitle":"Infineon CY7C1041G-10ZSXI 4Mbit Async SRAM, 10 ns","metaDescription":"Infineon CY7C1041G-10ZSXI 4Mbit (256K x 16) asynchronous SRAM with 10 ns access time, 4.5V-5.5V supply, -40°C to 85°C.
