72Mbit QDR II SRAM at 300 MHz — what the clock rate buys you
The Infineon CY7C1512KV18-300BZXI is a 72Mbit synchronous QDR II SRAM organized 4M x 18, clocked at 300 MHz. That 300 MHz clock is the headline number: it defines the peak data rate the memory can sustain on a QDR bus, where each clock edge transfers data on both the rising and falling edges. For a system that needs high-bandwidth, low-latency lookup tables or packet buffers — think network switches, base stations, or test equipment — this part delivers the throughput without the dead cycles of a standard synchronous SRAM.
Industrial temp and 1.7V–1.9V supply — fit for the environment
The 1.7V to 1.9V supply range is typical for low-voltage SRAM, but it's tight — your board's 1.8V rail needs to stay within 100 mV of nominal, especially during load transients. If your system runs a 1.5V or 2.5V I/O bank, this part won't drop in without a regulator.
