1Mb nvSRAM From Cypress With Quad Serial Peripheral Interface

Cypress Semiconductor Corp. introduced a 1Mb nonvolatile static random access memory (nvSRAM) with a Quad serial peripheral interface (SPI).

The interface enables the nvSRAM to exceed the data throughput of larger parallel interface devices with a smaller footprint. The nvSRAM ensures high-throughput data capture in event of a power loss without batteries for RAID storage, industrial automation, computing and networking applications.

The CY14V101QS 1Mb nvSRAM with Quad SPI interface works at a clock speed of up to 108 MHz and offers performance exceeding that of a parallel interface (x8 IO width, 45-ns access time) device. The nvSRAM provides 24MB/s random R/W access time with unlimited write endurance, and 20-year data retention. With its reduced I/O width, it offers reduced pin count and board footprint in a 16-pin SOIC package and 24-ball BGA package. The device includes an optional integrated real-time clock (RTC) with +/- 50ppm uncalibrated accuracy. The nvSRAM offers lower power consumption by a factor of 5.8 (active) and a factor of 10 (sleep) compared to competitive devices. A video on the device is available.

Company’s nvSRAMs are RoHS-compliant and directly replace SRAM, battery-backed SRAM, EPROM and EEPROM devices, offering reliable nonvolatile storage without batteries. Data transfers from the SRAM to the device’s nonvolatile elements take place automatically at power down. On power up, data is restored to the SRAM from the nonvolatile memory. Both operations are also available under software control.

“Mission-critical systems require high-performance memories that can capture data instantly and reliably on power loss,” said Sonal Chandrasekhar, director, nonvolatile products business unit, Cypress. “Cypress’s new 1Mb Quad SPI nvSRAM delivers fail-safe data security with the throughput performance of parallel devices in a small form factor ith low power consumption.“

Company’s nvSRAMs are manufactured on its SONOS (Silicon Oxide Nitride Oxide Silicon) embedded nonvolatile memory technology, enabling greater densities and improved access times and performance. nvSRAMs are solutions for applications requiring high performance and absolute nonvolatile data security such as RAID systems, PLCs, industrial data loggers, computing and networking systems, motor drives, routers and switches, avionics, defense systems, and gaming systems.

A provider in SONOS process technology, Cypress is using the technology in its PSoC mixed-signal arrays, programmable clocks and other products. SONOS is compatible with standard CMOS technologies and offers numerous advantages including high endurance, low power, and radiation hardness. The SONOS technology is qualified to run in company’s internal fab and in multiple foundry partner locations. The technology provides a superior solution in terms of scalability and manufacturability compared to other magnetic based nonvolatile memory technologies. The company has shipped more than two billion units that employ the SONOS process technology utilized in the nvSRAMs.

The CY14V101QS 1Mb nvSRAM is sampling with production expected in the third quarter of 2015.
