QDR SRAM — 18 Mbit at 167 MHz for high-throughput designs
The Cypress CY7C1306CV25-167BZC is a 18 Mbit synchronous QDR (Quad Data Rate) SRAM organized as 512K x 36 bits. It clocks at 167 MHz, delivering back-to-back read and write transactions on every rising and falling edge without bus-turnaround dead cycles — the hallmark of the QDR architecture.
Supply rail and temperature — narrow 2.5 V, commercial only
The part operates from a 2.4 V to 2.6 V supply, so the board needs a dedicated 2.5 V ±0.1 V rail — not a standard 3.3 V or 1.8 V memory bus. Plan for a local regulator if your system runs at a different core voltage.
Package — 165-ball FBGA, 13x15 mm
Housed in a 165-ball FBGA (13x15 mm body), the CY7C1306CV25-167BZC is a surface-mount BGA.
