The Infineon CY7C1413KV18-333BZC is a 36Mbit synchronous SRAM organized as 2M x 18, using QDR II architecture to deliver read and write data on both clock edges without bus-turnaround dead cycles. The 333 MHz clock yields a peak data rate of 666 MHz per pin pair, which is the throughput a network line card or telecom framer needs for packet buffer lookups without stalling the pipeline. The memory interface is parallel, and the supply range of 1.7V to 1.9V matches the core voltage of many 65 nm and 45 nm ASICs and FPGAs, saving a regulator rail. The 165-LBGA package (13x15 mm body) uses a 1.0 mm ball pitch, which routes cleanly on a standard 4-layer PCB with microvia fanout under the BGA.
This part is no longer available through the authorized factory channel and must be sourced from independent distribution or surplus inventory. Date-code and lot traceability become the primary concern — the laser etch on the package top and the tray markings should be cross-checked against Infineon's factory format for that production week. Any re-marked or sanded parts are a red flag.
