1 Mbit asynchronous SRAM for industrial parallel buses
The operating temperature range of -40°C to 85°C qualifies it for industrial environments — motor drives, outdoor telecom cabinets, and factory automation panels where the ambient temperature swings beyond office limits. The 32-sTSOP footprint (11.80 mm body width) is a common SRAM land pattern; board layouts for this package can often accommodate higher-density MoBL® parts with the same pinout.
45 ns access time — what it means for the bus
The 45 ns access time is the interval from address assertion to valid data on the outputs. The write cycle time is also 45 ns.
Active lifecycle — no end-of-life risk for new builds
Infineon lists the CY62128EV30LL-45ZAXI as Active. There is no NRND flag, no last-time-buy window, and no announced discontinuation. The MoBL® series remains an active product line, so cross-die shrinks or package changes would come through a PCN, not a sudden EOL.
