The Infineon CY7C1380D-167BZC is a 18 Mbit synchronous SDR SRAM organized 512K x 36, clocked at 167 MHz with a 3.4 ns access time. It operates from a 3.135 V to 3.6 V supply and is housed in a 165-ball FBGA (13x15 mm) for surface-mount assembly. This is a parallel-interface, volatile memory part intended for high-speed cache, buffer, and lookup-table applications in networking, telecom, and computing equipment where wide-word (36-bit) data paths with parity or ECC are standard.
167 MHz clock, 3.4 ns access — timing margin for bus design
The 167 MHz clock rate and 3.4 ns access time define the timing budget for the memory bus. The 36-bit wide data path means 36 DQ lines plus address and control must all close timing within the same cycle.
Temperature grade and environment
Rated for 0°C to 70°C ambient — commercial temperature grade. This limits the part to indoor, temperature-controlled environments such as central-office telecom, data-center networking, and lab-grade instrumentation. Not rated for industrial or automotive extended-temperature ranges.
