The 12 ns access time sets the bus timing margin for the memory controller — the address-to-data valid window is tight enough for high-speed 5V logic systems but requires the controller's setup/hold to account for the full 12 ns max, not the typical value. The SOJ footprint is a legacy JEDEC standard for through-hole-like reliability in a surface-mount form — the J-bend leads absorb board flex better than a gull-wing in high-vibration environments. ## Industrial temperature grade and 5V supply rail The write cycle time is also 12 ns (word/page mode), matching the read access — no penalty for mixed read/write traffic in the same bus cycle.","metaTitle":"Infineon CY7C199CN-12VXIT 256Kbit SRAM, 12 ns, 28-SOJ","metaDescription":"Obsolete 256Kbit asynchronous SRAM, 32K x 8, 12 ns access, -40°C to 85°C, 28-SOJ.
