It is designed for applications requiring low standby power and a wide voltage supply range of 2.2 V to 3.6 V, making it suitable for battery-backed or single-rail systems in industrial control, telecom infrastructure, and portable instrumentation. The 55 ns access time and 55 ns write cycle time align with mid-speed bus controllers and CPLD/FPGA glue logic, while the industrial temperature range (-40°C to 85°C) qualifies it for factory-floor and outdoor deployment. ## 55 ns access time — what it means for bus timing The 55 ns access time sets the window for the memory to present valid data after the address is latched. The 55 ns write cycle time is symmetric, so read-modify-write sequences do not stall. ## Package and footprint: 44-TSOP II Housed in a 44-TSOP II (0.400\" body width, 10.16 mm), this surface-mount package is a common footprint for mid-density asynchronous SRAMs. ## Lifecycle and compliance The MoBL series is Infineon's low-power asynchronous SRAM family, and the CY62146DV30L-55ZSXI remains a standard catalog item through independent distribution.","metaTitle":"CY62146DV30L-55ZSXI Infineon MoBL SRAM, 4Mbit, 55 ns","metaDescription":"Infineon CY62146DV30L-55ZSXI MoBL asynchronous SRAM, 4Mbit (256K x 16), 55 ns access, 2.2V–3.6V, -40°C to 85°C.

It is not a pin-compatible drop-in — the package is different (BGA vs TSOP). For a form-fit-function replacement in the same 44-TSOP footprint, the CY7C1041G30-10ZSXA is closer, though still 10 ns.
