The industrial temperature grade (-40 to +85 °C) covers factory-floor, outdoor telecom cabinet, and unheated enclosure deployments. Housed in a 32-SOIC (0.445-inch body width, 11.30 mm), the same footprint used by legacy 128K x 8 SRAMs from multiple vendors. Supplied in tube. The write cycle time matches the read access at 45 ns — byte-wide writes complete in one cycle with no page-mode or burst overhead. ROHS3 compliant, with no exemption-based restrictions that would block EU or California market entry. The part belongs to the MoBL (Motherboard Battery-Less) series — Infineon's low-power asynchronous SRAM family characterized by reduced standby current.","metaTitle":"Infineon CY62128EV30LL-45SXI MoBL SRAM, 1Mbit, 45ns, 32-SOIC","metaDescription":"Infineon CY62128EV30LL-45SXI MoBL asynchronous SRAM, 1Mbit (128K x 8), 45 ns access, 2.2-3.6 V, -40 to +85 °C, 32-SOIC.
