Product details

72Mbit DDR II SRAM at 400 MHz

The CY7C1570V18-400BZXC is a 72Mbit synchronous DDR II SRAM from Infineon, organized as 2M x 36. The 400 MHz clock rate targets high-throughput applications such as network line cards, telecom switches, and high-end test equipment where back-to-back read/write cycles without dead cycles are critical.

Supply rails and temperature envelope

165-ball FBGA footprint

Housed in a 165-ball LBGA (15x17 mm body). The package is surface-mount only; no through-hole alternative exists.

Infineon lists the CY7C1570V18-400BZXC as Obsolete. No last-time-buy window or official successor is recorded in the available documentation.
