450 MHz DDR II+ SRAM — what it does and where it fits
The Infineon CY7C1248KV18-450BZXC is a 36Mbit synchronous DDR II+ SRAM organized as 2M x 18 bits, clocked at 450 MHz. It is a volatile, parallel-interface memory.
Supply and temperature — the operating envelope
Core supply is 1.7 V to 1.9 V. The 0°C to 70°C commercial temperature grade limits this part to indoor, climate-controlled environments. The 165-ball FBGA package (13x15 mm) requires a multi-layer PCB with via-in-pad capability.
Obsolete — what that means for procurement
This part is marked obsolete by the manufacturer. No last-time-buy window is available; production has ended. For a BOM line that calls out the CY7C1248KV18-450BZXC, the only sourcing path is the independent surplus and broker channel.
Memory organization — why 2M x 18 matters
The 2M x 18 organization means the part presents an 18-bit-wide data bus. It is sized for systems that need an 18-bit word.
