The 15 ns write cycle time (word, page) matches the read access, so the bus timing is symmetric — no wait-state penalty on writes that the read side does not also see. Supplied in a 28-TSSOP (0.465\", 11.80 mm width) body, the supplier device package is 28-TSOP I — a standard thin small-outline package with a 0.55 mm lead pitch. Infineon lists this part as Obsolete. Sourcing is through independent distribution; quantities are lot-specific and confirmed at RFQ.","metaTitle":"Infineon CY7C199CL-15ZXC 256Kbit SRAM, 15 ns, 28-TSOP","metaDescription":"CY7C199CL-15ZXC 256Kbit asynchronous SRAM, 15 ns access, 4.5-5.5 V, 28-TSOP I.
