The 45 ns access time and 45 ns write cycle time (word/page) set the bus timing budget — the processor's memory controller must accommodate this window for read and write operations without wait states if the clock period allows. ## Supply voltage and temperature grade The wide range allows the same part to serve across different supply domains without a separate regulator. Supplied on Tape & Reel (TR) with Cut Tape (CT) option, the packaging supports automated pick-and-place assembly and reel-fed production lines. Store the reels in a dry environment per JEDEC moisture sensitivity level handling.","metaTitle":"CY621472G30-45ZSXIT SRAM, 4Mbit, 45 ns, 44-TSOP II","metaDescription":"Infineon MoBL® asynchronous SRAM, 4Mbit (256K x 16), 45 ns access, 2.2V-3.6V, -40°C to 85°C, 44-TSOP II.
