The Infineon CY7C1305BV25-167BZCT is a 18 Mbit synchronous SRAM using the QDR (Quad Data Rate) architecture, organized as 1M x 18. It clocks at 167 MHz and communicates over a parallel interface, delivering back-to-back read and write transactions without dead cycles — the defining advantage of QDR over standard synchronous SRAM.
165-ball FBGA — footprint and rework considerations
The package is a 165-ball FBGA measuring 13x15 mm (supplier device package 165-FBGA). For rework or replacement, the part is surface-mount only and requires a controlled hot-air profile.
The CY7C1305BV25-167BZCT carries an official Obsolete lifecycle status. If a production program requires a long-term supply, a qualification effort to a currently active QDR SRAM family from the same or alternate vendor should be planned.
