Features & Applications

Cypress's More Battery Life™ (MoBL®) SRAMs dominate the low-power SRAM market with the industry's widest portfolio, starting from low (64 Kb) to very high densities (extending up to 64 Mb) with standard voltage (nominal) and bus-width options, at the cutting edge of process technology.

Cypress More Battery Life™ (MoBL®) SRAMs offer best-in-class access times (45 ns) with the industry's lowest Standby Power Dissipation (Maximum), making them the ideal high-performance, high-battery life memory solutions for mobile phones, PDAs, Point of Sale (POS) terminals, handheld radio-sets/gaming machines, Automotive Audio, ECU, Navigation and Telematics Systems.

Cypress More Battery Life™ (MoBL®) can be designed-in with a battery and a memory controller, to be used as Super-Fast Non-Volatile-SRAM for security circuitry, with a non-volatile memory life of 7 to 9 years.

The Micropower SRAMs are offered in industry standard packaging options (RoHS-compliant) in Industrial and Automotive Temperature Range.

The CY62157ELL-45ZSXI is an Ultra Low Power 8 Mbit SRAM organized as 512K words by 16 bits with a speed of 45ns, available in a 44-pin TSOP II  package and has industrial temperature specifications.

This device features advanced circuit design to provide ultra low active current. This is ideal for providing More Battery Life™ (MoBL®) in portable applications such as cellular telephones. The device also has an automatic power down feature that significantly reduces power consumption when addresses are not toggling.
