The write cycle time matches at 20 ns for word and page writes. The industrial temperature range (-40°C to 85°C) suits outdoor or engine-bay deployment where ambient swings are wide. ## 28-TSSOP — hand-solderable but fine-pitch The supplier device package is 28-TSOP I — the same footprint, different naming convention. Supplied in Tape & Reel (TR) — the reel quantity is not stated, but the TR suffix in the order code confirms reel packaging for automated pick-and-place.","metaTitle":"Infineon CY7C199CN-20ZXIT 256Kbit SRAM, 20 ns, 28-TSSOP","metaDescription":"Obsolete 256Kbit asynchronous SRAM from Infineon. 20 ns access, 5V supply, industrial temp.
