The 55 ns access time sets the read-cycle floor for the memory bus — a 55 ns window means the address-to-data valid delay, so the controller must hold the address stable for at least that long before latching the output. At a 4.5V supply, this part operates on a nominal 5V rail, making it a drop-in for legacy 5V logic systems without a level translator. The extended temperature grade means the timing parameters are guaranteed across the full range, not just at 25°C — a critical factor for outdoor telecom, engine bay controllers, or factory-floor equipment that sees thermal cycling.","metaTitle":"CY62256LL-55ZXET SRAM 256Kbit 55 ns Parallel MoBL","metaDescription":"Infineon CY62256LL-55ZXET 256Kbit (32K x 8) parallel SRAM, 55 ns access time, -40°C to 125°C, 4.5V supply, 28-TSOP I.
