The 18-bit word width suits designs that need parity or ECC alongside the data bus — common in network buffers, cache tag stores, and telecom line cards. Supply runs 3.15 V to 3.6 V, and the part is specified over the commercial 0°C to 70°C range, so it fits indoor, temperature-controlled equipment. ## Last-time-buy — final procurement window","metaTitle":"Cypress CY7C1327G-166AXC Synchronous SRAM, 4.5 Mbit, 166 MHz, 3.5 ns","metaDescription":"Cypress CY7C1327G-166AXC synchronous SRAM, 4.5 Mbit (256K x 18), 166 MHz clock, 3.5 ns access, 3.15V–3.6V, 0°C–70°C, 100-TQFP.
