The Cypress CY7C13201KV18-300BZXC is a 18Mbit synchronous DDR II SRAM organized as 512K x 36, clocked at 300 MHz. It operates from a 1.7 V to 1.9 V supply and is rated for 0°C to 70°C commercial environments. The part comes in a 165-FBGA (13x15 mm) package for surface-mount assembly.
The 300 MHz clock rate defines the minimum acceptable controller timing.
This part is officially obsolete per the manufacturer's lifecycle status. No last-time-buy window remains open; new production has ceased. Sourcing is through independent distribution and surplus channels only. No direct replacement is listed by Cypress; any substitute requires a pin-compatible and function-compatible evaluation.
