The CY62138CV25/30/33 and CY62138CV are high-performance CMOS static RAMs organized as 256K words by eight bits. This device features advanced circuit design to provide ultra-low active current. This is ideal for providing More Battery Life™ (MoBL®) in portable applications. The device can be put into standby mode reducing power consumption by more than 99% when deselected (CE1 HIGH or CE2 LOW).
The CY62138CV family provides 256K‑word by 8‑bit (2 Mbit) CMOS static RAMs designed for portable applications. Variants CY62138CV25, CY62138CV30, CY62138CV33 and the generic CY62138CV cover voltage ranges from 2.2 V to 3.6 V and feature ultra‑low active current and an automatic power‑down mode that reduces consumption by up to 80 % when idle.
The device is supplied in a 36‑ball FBGA package and includes detailed electrical characteristics such as 55 ns typical access time, 1.5 mA typical active current at 1 MHz, and standby power reduction of more than 99 % when deselected. Thermal resistance, input/output capacitance, and maximum ratings are also specified for reliable integration into high‑performance designs.
