What is this part and where does it go?
The Infineon CY7C1515AV18-200BZXI is a 72Mbit QDR II synchronous SRAM organized as 2M x 36, clocked at 200 MHz over a parallel interface. This part is built for high-bandwidth, low-latency data buffering in networking gear, telecom line cards, and high-end test equipment where the QDR II architecture eliminates bus-turnaround dead cycles.
At 200 MHz, the QDR II interface delivers two data words per clock cycle on separate read and write ports, effectively doubling the data rate compared to a conventional synchronous SRAM at the same clock. For a 36-bit-wide bus, that translates to a peak bandwidth of 1.6 GB/s (200 MHz × 36 bits × 2 transfers per clock ÷ 8). The 2M x 36 organization gives you 2 million addressable locations, each 36 bits wide — a natural fit for 32-bit data words plus parity or ECC bits.
That means a hot-air station or reflow oven for removal; no socket, no hand-solder swap in the field. If you are maintaining boards with this part, plan for a pre-bake if the board has been exposed to humidity (MSL 3 is standard for this class of BGA).
