The Infineon CY7C1570KV18-450BZC is a 72 Mbit synchronous SRAM with a DDR II+ interface, organized as 2M x 36 bits and clocked at 450 MHz. It is a volatile, parallel-bus memory designed for high-throughput buffer applications in networking switches, telecom line cards, and FPGA-attached cache where back-to-back read-write cycles must sustain full bus rate without dead cycles. The 1.7 V to 1.9 V core supply and 165-ball FBGA package (13x15 mm) target dense PCB layouts with a dedicated memory controller or high-end FPGA.
2M x 36 organization and commercial temperature grade
The 36-bit word width is common in systems that carry ECC or parity alongside the data payload.
Package and supply voltage
The 165-ball FBGA (13x15 mm) uses a ball pitch typical of mid-density BGA memories.
