At 167 MHz, the QDR II interface delivers a peak bandwidth of 333 million transfers per second per 18-bit port (read and write each get their own port). That translates to roughly 6 Gbps of raw I/O bandwidth across the two ports. For a system designer, the key takeaway is that the bus timing margin at this speed is tight — the 1.7–1.9 V supply needs to be clean and within 3% of the target, and the PCB trace length matching between the address/control and data buses should be held to within 50 ps of skew to avoid setup/hold violations. This is not a part you drop into a noisy 1.8 V rail shared with a switching regulator without a pi-filter. Cypress (now part of Infineon) no longer manufactures it, and no official successor part number has been recorded. If you are designing a new board, do not plan this part in; look at current-generation QDR II+ or QDR IV parts from Infineon or Renesas for a drop-in or near-drop-in alternative. ## Package and board integration notes It is surface-mount only, and the 1.7–1.9 V core supply means the board needs a dedicated 1.8 V rail — do not share it with 1.8 V I/O banks on an FPGA that might draw transient current spikes.","metaTitle":"Cypress CY7C1412AV18-167BZXI 36Mbit QDR II SRAM, 167 MHz","metaDescription":"Cypress CY7C1412AV18-167BZXI 36Mbit synchronous QDR II SRAM, 167 MHz clock, 2M x 18, 1.7-1.9V, 165-LBGA, -40 to 85°C.
