The Cypress CY7C2270KV18-550BZXI is a 36Mbit synchronous SRAM using a DDR II+ parallel interface, clocked at 550 MHz. Organized as 1M x 36, it operates from -40 to 85 °C and comes in a 165-FBGA (13x15 mm) package.
At 550 MHz, the DDR II+ interface transfers data on both clock edges. The 1.7 to 1.9 V core supply keeps I/O power reasonable for dense memory arrays.
The CY7C2270XV18-600BZXC is a pin-compatible sibling with a 600 MHz clock speed, but it is rated for commercial temperature (0 to 70 °C) only. It will drop into the same PCB footprint and supply voltage, but verify your thermal environment before substituting for an industrial-temperature design.
It is supplied in a 165-ball FBGA (13x15 mm) package, surface-mount only. The listing shows the packaging form as Bulk, meaning loose trays rather than tape-and-reel.
