The Infineon CY7C1415KV18-250BZCT is a 36Mbit Quad Data Rate II synchronous SRAM organized as 1M x 36, clocked at 250 MHz. The QDR-II architecture eliminates the read-write bus-turnaround dead cycle by dedicating separate read and write ports, delivering back-to-back throughput at the full clock rate.
Supply rail and temperature grade
Runs on a 1.7V to 1.9V supply, nominally 1.8V.
This part is marked Obsolete by Infineon. No official successor order code is listed in the available records. For BOM lines that still require this exact density and speed grade, procurement goes through the independent surplus and broker channel. If you are evaluating a pin-compatible drop-in, the QDR-II 36Mbit family from Cypress (now Infineon) shares the same 165-ball FBGA footprint and 1.8V supply across multiple speed grades, but verify the specific configuration register settings against your controller.
