1Mb no-battery serial SPI nvSRAM from Cypress and Anvo-Systems

If you're hunting for battery-less 1MB serial nvSRAM chips, we suggest you two new products from different vendors based on nearly same technology. One is from the Cypress Semiconductor, pioneer of this technology, and the other is from Germany-based Anvo-Systems Dresden, who fully focuses on this technology. The new nonvolatile SRAM chips from Cypress Semiconductor comes with Quad serial peripheral interface (SPI) with access time of 45 ns and operating at 108 MHz clock speed. Cypress uses SONOS (Silicon Oxide Nitride Oxide Silicon) technology in making these nvSRAMs. SONOS is compatible with standard CMOS technologies and offers advantages such as high endurance, low power, and radiation hardness. nvSRAM provides 24MBps random read/write access time with unlimited write cycles with data retention life of 20 years. Cypress semiconductor is already offering nvSRAM chips with parallel interface, now with these SPI interface chips, the size of the chip comes down and also your PC board. CY14V101QS 1Mb nvSRAM is available in16-pin SOIC package and 24-ball BGA package. The device also includes an optional integrated real-time clock (RTC) with +/- 50ppm uncalibrated accuracy. Cypress says its nvSRAM chips offers lower power consumption by a factor of 5.8 (active) and a factor of 10 (sleep) compared to competitive devices. The CY14V101QS 1Mb nvSRAM is sampling tod...
