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 This limits deployment to controlled environments.","metaTitle":"Infineon CY7C1386D-167AXCT 18Mbit SRAM, 167 MHz, 3.4 ns","metaDescription":"Infineon CY7C1386D-167AXCT synchronous SDR SRAM, 18Mbit 512Kx36, 167 MHz clock, 3.4 ns access, 3.135V–3.6V, 100-TQFP, tape-and-reel.
