The CY62137CV25/30/33 and CY62137CV are high-performance CMOS static RAMs organized as 128K words by 16 bits. These devices feature advanced circuit design to provide ultra-low active current. This is ideal for providing More Battery Life™ (MoBL®) in portable applications such as cellular tele- phones.
The CY62137CV family (including CY62137CV25, CY62137CV30, and CY62137CV33) are high‑performance CMOS static RAMs organized as 128K words by 16 bits. They offer very high speed (55 ns or 70 ns), ultra‑low active power, and automatic power‑down when deselected, making them suitable for portable applications such as cellular phones.
The datasheet details the functional description, pin configuration, maximum ratings, electrical characteristics, data‑retention behavior, switching timing, and package information (48‑ball FBGA). It also includes a document history and revision notes for engineers designing with these parts.
