36 Mbit QDR-II SRAM at 300 MHz — throughput and bus architecture
The CY7C1412KV18-300BZXC is a 36 Mbit synchronous QDR-II SRAM organized as 2M x 18 bits, clocked at 300 MHz. QDR-II architecture provides separate read and write data ports, each operating on both clock edges, so the bus never stalls for turn-around cycles — the effective data rate is 600 MHz DDR per port. This makes it a fit for high-bandwidth buffer applications like packet processing in network line cards, where the read and write streams are independent and the memory must keep up with back-to-back transactions without arbitration gaps.
Package, supply, and temperature — board-fit constraints
Housed in a 165-ball FBGA measuring 13 x 15 mm, the part requires a multi-layer PCB for fan-out of the fine-pitch balls. The core supply rail must be regulated to 1.7 V–1.9 V; a nominal 1.8 V rail with ±3% tolerance keeps the die within spec across load transients. The commercial temperature range (0°C to 70°C) limits deployment to indoor, controlled-environment equipment — telecom central offices, data-centre switches, and test instrumentation. For extended-temperature designs, a different temperature grade would be required.
