72Mbit DDR II+ SRAM at 500 MHz
Its 500 MHz clock rate delivers back-to-back read/write throughput without dead cycles, which is the key decision metric for high-bandwidth data buffers in networking, telecom line cards, and test equipment.
500 MHz — what that buys the bus
At 500 MHz the DDR II+ interface transfers data on both clock edges, so the effective data rate is 1 Gbps per pin. That bandwidth justifies the 165-ball FBGA footprint (13x15 mm) because the signal-integrity budget at these edge rates demands a controlled-impedance layout with tight via stitching and decoupling under the BGA. The 1.7V to 1.9V core rail keeps dynamic power in check, but the thermal pad — though not an exposed paddle — still needs a solid ground-plane connection to the eight inner balls for heat spreading.
Industrial temperature and where it runs
The 1.7V minimum supply gives headroom for a 1.8V rail with 100 mV of droop during load transients.
The lifecycle status for the CY7C1570KV18-500BZXI is Obsolete.
