Mobile-optimised SRAMs deliver more battery life, by design

To enable mobile systems that meet stringent demands for performance on the move, Cypress Semiconductor has prioritised More Battery Life (MoBL™) in its MicroPower SRAMs offering fast read/write performance and the lowest possible power dissipation throughout operational and standby modes.

Cypress’ MoBL SRAMs offer best-in-class access times of 45ns and are specially designed to save power throughout all modes. Patented techniques reduce supply current to 10mA (typical) for a 2Mbit MoBL device at 3.6V, which is 70-90% less than a standard SRAM. Moreover, the standby current of 10µA at 3.6V and 2µA at 1.8V saves power when the SRAM is deselected, while also allowing internal data to be retained. Another power-saving aspect is the low data-retention voltage of 1.0V. MoBL devices are also designed for a wide supply-voltage range, resulting in only minor degradation in access time when operating with a lowvoltage host processor or ASIC.

For maximum ease of use, Cypress’s MoBL MicroPower SRAMs are available in industrystandard package styles including FBGA, VFBGA, SOIC, STSOP, TSOP, TSOP II and PDIP, and are specified for industrial and automotive temperature ranges.
