The CY7C1414BV18-200BZI is a 36Mbit synchronous QDR II SRAM from Cypress (now Infineon), organized as 1M × 36 and clocked at 200 MHz. QDR II architecture separates read and write data ports, eliminating bus-turnaround dead cycles — each port operates at the full 200 MHz rate, delivering back-to-back throughput that standard synchronous SRAM cannot match.
No last-time-buy window remains open from the factory. If your design can tolerate a form-fit-function alternate, a QDR II+ or QDR IV part from the same Cypress family may be a candidate, but no official pin-compatible successor is listed for this specific density and speed grade.
