The CY7C0430BV-100BGC is marked obsolete by Infineon.
1.152 Mbit quad-port synchronous SRAM at 100 MHz
Organized as 64K words by 18 bits, the 1.152 Mbit memory provides four independent ports for simultaneous read/write access — a fit for shared-memory architectures in network switches, base stations, or multi-processor systems where contention-free access matters. The 100 MHz clock sets the interface data rate; with a parallel interface, each port can sustain a 100 MHz read or write cycle. Supply range is 3 V to 3.6 V, typical for 3.3 V logic families.
Temperature grade and board-fit
Surface-mount in the 272-PBGA; the bag packaging means parts arrive in anti-static bags, not tape-and-reel — factor this into pick-and-place handling if the line expects reeled components.
