Infineon lists the CY7C109B-12ZXCT as obsolete.
The part comes in a 32-TSOP I package (0.724" body width, 18.40 mm), surface-mount, supplied in Tape & Reel. The 32-TSOP I footprint is a standard JEDEC outline used across many 1 Mbit asynchronous SRAMs, so the board layout should accept other 32-TSOP I parts if a second source is needed.
Infineon has not published an official successor order code for this part.
