18 Mbit synchronous SRAM for high-speed parallel cache
The Infineon CY7C1386D-167AXCT is a 18 Mbit synchronous SRAM organized as 512K x 36, clocked at 167 MHz with a 3.4 ns access time. It uses a parallel interface and operates from a 3.135 V to 3.6 V supply. The 36-bit wide data bus suits designs that carry parity or ECC alongside the data word — common in networking line cards, telecom switch fabrics, and high-end cache buffers where the extra width avoids a second memory bank.
Commercial temperature range — indoor equipment only
The operating temperature range is 0°C to 70°C (TA), the commercial grade. This limits deployment to controlled environments.
