Obsolete — what it means for the BOM line
The CY7C199C-20ZXIT: New designs should not target this part; existing BOM lines rely on surplus or broker channels for continued supply.
Parametric profile and fit
The CY7C199C-20ZXIT is a 256 Kbit asynchronous SRAM organized as 32K x 8 bits with a 20 ns access time.
Housed in a 28-TSSOP (0.465", 11.80 mm width) body, the supplier device package is 28-TSOP I. Surface-mount assembly with tape-and-reel packaging supports automated pick-and-place. The parallel memory interface requires 32 address/data lines plus control signals routed to the host.
