The Infineon CY7C1623KV18-333BZXC is a 144 Mbit synchronous DDR II SRAM organized as 8M x 18 bits. It runs from a 1.7 V to 1.9 V core supply and clocks at 333 MHz, giving a burst data rate that matches high-bandwidth datapaths in networking, telecom, and test equipment. The parallel memory interface and the 165-ball FBGA footprint (15x17 mm) place it squarely in the class of fast cache or packet-buffer memory that needs back-to-back read-write throughput without dead cycles.

Frequently asked questions
What is the closest pin-compatible alternative to CY7C1623KV18-333BZXC?
Infineon does not list a direct pin-compatible replacement for this exact speed and density variant. Within the CY7C1623 family, a different speed grade (e.g., -300 or -250) or a different package option may be available, but each must be verified for pinout and timing compatibility against the original PCB layout.
What package does CY7C1623KV18-333BZXC use?
It comes in a 165-ball FBGA (15x17 mm) package, supplied in a tray.
What is the memory technology of CY7C1623KV18-333BZXC?
It is a synchronous DDR II SRAM — volatile memory with a parallel interface, organized as 8M x 18 bits.
