72Mbit NoBL synchronous SRAM — 167 MHz, 3.4 ns access
It operates with a 167 MHz clock and delivers a 3.4 ns access time, making it suited for high-bandwidth data buffering in networking switches, telecom line cards, and high-end test equipment where back-to-back read/write throughput matters.
Supply and temperature — 2.5 V, commercial grade only
The supply range is 2.375 V to 2.625 V — a 2.5 V nominal rail, not 1.8 V or 3.3 V. If your memory bus runs at 2.5 V, this part drops in without level shifters; otherwise budget translation.
Package — 165-FBGA (15x17 mm)
Housed in a 165-ball fine-pitch BGA (15x17 mm body), surface-mount only. The 1.0 mm ball pitch requires controlled impedance routing and a multi-layer PCB. No exposed thermal pad — heat dissipation is through the BGA balls and the board plane. MSL rating is not in the record, but typical Cypress BGA SRAMs are MSL 3; verify the moisture sensitivity before reflow if the original packaging seal is broken.
The CY7C1470V25-167BZC is listed as Obsolete. Cypress (now part of Infineon) no longer manufactures this exact ordering code.
