144 Mbit DDR II+ SRAM at 450 MHz — what it is and where it fits
The 0°C to 70°C commercial temperature range means this part is for indoor, climate-controlled racks — not for a factory floor or an outdoor cabinet without active cooling.
Lifecycle — the sourcing reality
The record shows a conflict: the lifecycle stage is flagged as end-of-life / hot (eol_hot), while the product status reads Active. This ambiguity is the first thing to resolve before committing a BOM line. If Infineon has issued a PCN or last-time-buy notice, the window for factory orders may be closing. We source this part to order against an RFQ through independent distribution — availability and current pricing are confirmed at quote time. If you need a drop-in for a panel originally built around the CY7C1562XV18-450BZXC, note that the 72 Mbit part is 4M x 18, not 4M x 36; the footprint and pinout differ, so a board respin is required.
