The 300 MHz clock rate supports double-data-rate read and write ports. Operating from a 1.7 V to 1.9 V supply, this part is rated over the industrial temperature range of -40°C to 85°C, so it can sit in outdoor cabinets or factory-floor enclosures without derating. The 165-ball FBGA (15x17 mm) package requires a multi-layer PCB with controlled impedance for the parallel bus. ## Memory organization and bus width The 4M x 36 organization provides a 36-bit wide data bus per port with independent read and write ports in QDR II+. The 144Mbit density suits moderate-depth buffers.","metaTitle":"CY7C2644KV18-300BZXI Cypress QDR II+ SRAM, 144Mbit, 300 MHz","metaDescription":"Cypress (Infineon) QDR II+ synchronous SRAM, 144Mbit organized 4M x 36, 300 MHz clock, 1.7–1.9 V supply, 165-ball FBGA, -40°C to 85°C, tray.
