350 MHz QDR II SRAM — 72Mbit in a 165-ball FBGA
The Infineon CY7C1512KV18-350BZC is a QDR II synchronous SRAM organized 4M x 18, clocked at 350 MHz, and supplied from a 1.7V to 1.9V rail. This is a high-bandwidth memory part for networking and telecom line cards where the parallel interface and double-data-rate architecture sustain the throughput a single-port SRAM cannot reach.
This part is marked obsolete by the manufacturer.
The device operates from 1.7V to 1.9V, which aligns with the 1.8V nominal QDR II supply. If the application sees extended thermal cycling or cold start below freezing, a wider-temperature variant would be needed.
