The 3.4 ns access time from clock edge to data valid gives the controller a tight but manageable setup/hold window — budget for PCB trace delay and clock skew when routing the data bus. At this speed, signal integrity on the parallel bus matters; keep trace lengths matched and use series termination near the SRAM pins. ## 100-TQFP package — footprint and rework notes It is a surface-mount package suited for standard reflow soldering. For rework, use a hot-air nozzle sized to the body; preheat the board to 100–120°C to avoid thermal shock. ## Commercial temperature range — deployment boundary Not qualified for industrial enclosures, outdoor cabinets, or under-hood automotive use. If your application sees extended temperature swings, look at industrial-temperature (-40°C to 85°C) synchronous SRAMs in the same Cypress family. Cypress has discontinued this exact variant. For new designs, consider a current-production synchronous SRAM with similar speed and density from Cypress (now Infineon) or an alternate vendor.","metaTitle":"CY7C1387D-167AXC Cypress 18Mbit Synchronous SRAM, 167 MHz","metaDescription":"CY7C1387D-167AXC Cypress 18Mbit synchronous SRAM, 1M x 18, 167 MHz clock, 3.4 ns access, 100-TQFP.
