72 Mbit DDR II+ SRAM at 333 MHz
The CY7C1518KV18-333BZI is a 72 Mbit synchronous SRAM with a DDR II+ interface, organized as 4M x 18. The 333 MHz clock rate delivers a peak read/write bandwidth that suits high-throughput packet buffers, cache, and DSP memory pools.
The supplier device package is 165-FBGA (13x15). Supplied in tray format — suitable for hand-place prototypes or pick-and-place reflow. The package is surface-mount; no special handling beyond standard BGA moisture bake (MSL level not stated in this record).
No official successor or pin-compatible second source is listed in the available record.
Memory interface and timing
The parallel memory interface uses DDR II+ signaling — data is clocked on both edges of the 333 MHz clock, effectively doubling the data rate. The 18-bit wide data bus (4M x 18) allows a single chip to serve a 16-bit data word plus parity or ECC bits.
