With a 70 ns access time and matching 70 ns write cycle, it is a drop-in replacement for legacy 28-SOIC footprint designs needing 5 V ± 10 % supply. ## 70 ns access and write cycle — timing margin for 5 V buses The 70 ns access time and 70 ns write cycle time set the minimum read/write pulse width the bus master must respect. For a 5 V system running at 10-12 MHz, the 70 ns window leaves enough margin for address decode and data setup without wait states, assuming the controller's output hold time is within spec. Operating temperature range is 0 °C to 70 °C (TA), which covers commercial and indoor industrial environments. ## Active lifecycle — no EOL concern for legacy BOMs This makes it a safe choice for sustaining a legacy 5 V SRAM BOM line without immediate redesign pressure. ## 28-SOIC package — board-fit compatibility Housed in a 28-SOIC (0.295\", 7.50 mm width) surface-mount package, the part uses the standard JEDEC SOIC-28 wide-body footprint. The 1.27 mm pin pitch is compatible with common SOIC-28 land patterns. Supplied in bulk tube packaging.","metaTitle":"CY62256NLL-70SNCT MoBL SRAM, 256Kbit, 70ns, 28-SOIC","metaDescription":"Infineon (Cypress) MoBL 256Kbit asynchronous SRAM, 70ns access, 4.5-5.5V, 28-SOIC.
