250 MHz DDR II SRAM — what it means for the bus
The CY7C1423KV18-250BZXC is a 36Mbit DDR II synchronous SRAM organized as 2M x 18. It clocks at 250 MHz.
Package and footprint
Housed in a 165-ball FBGA (13×15 mm), surface-mount only. The fine-pitch BGA demands a well-controlled reflow profile and X-ray inspection after assembly — no hand-soldering this one. The 165-LBGA footprint is shared across the CY7C1423 density family, so a board laid out for the 36Mbit part can accept a lower-density variant without a spin.
Lifecycle reality — EOL, not active
The lifecycle status on this part is end-of-life (EOL). Cypress (now Infineon) has stopped production.
Sourcing posture
Because this part is EOL, it is sourced exclusively through the independent channel. We can quote it to order against an RFQ; availability and current pricing are confirmed at quote time. No lead-time number is possible from the factory — the only supply is what exists on the open market.
