A 55 ns access time means the SRAM can complete a read or write cycle in 55 ns from address assertion. This is a relaxed timing compared to modern 10 ns or 12 ns parts, but it is intentionally matched to slower microcontrollers (e.g., 8-bit or 16-bit MCUs running below 20 MHz) or to systems where the bus timing is already gated by other peripherals. For a legacy 8051 or a ColdFire bus running at 8–12 MHz, the 55 ns window is comfortable. ## Industrial temperature and 5V rail If your design migrated to 3.3V, look at the 3V MoBL variants (e.g., CY7C1018DV33) which are pin-compatible but operate at 3.0V to 3.6V. The 32-SOIC (300-mil wide) footprint is common and socket-friendly for prototyping.","metaTitle":"CY62128ELL-55SXE Infineon MoBL SRAM, 1 Mbit, 55 ns, 32-SOIC","metaDescription":"Infineon CY62128ELL-55SXE asynchronous SRAM, 1 Mbit (128K x 8), 55 ns access, -40 to 125°C, 32-SOIC.
