Cypress Semiconductor has introduced a new type of 1Mb non-volatile static random access memory (nvSRAM) with a Quad Serial Peripheral Interface (SPI). The Quad SPI interface enables the new nvSRAM to exceed the data throughput of large parallel interface devices with a small footprint. nvSRAM ensures high-throughput data capture during power outages without the need for batteries for RAID storage, industrial automation, computing, and networking applications.
The CY14V101QS 1Mb nvSRAM with Quad SPI interface operates at clock speeds up to 108 MHz and provides performance that exceeds the performance of parallel interface (x8 IO width, 45 ns access time) devices. nvSRAM provides 24MBps of random read / write access time with unlimited write endurance and 20-year data retention time. With reduced I / O width, it provides less pin count and board area in a 16-pin SOIC package and a 24-ball BGA package. The device also includes an optional integrated real-time clock (RTC) with uncalibrated accuracy of +/- 50ppm. Compared to competing products, nvSRAM reduces power consumption by 5.8 (active) and 10 (sleep).
Cypress nvSRAM meets RoHS requirements and can directly replace SRAM, battery-powered SRAM, EPROM and EEPROM devices, providing reliable non-volatile data storage without batteries. Data transfer from SRAM to the device's non-volatile elements occurs automatically when power is lost. At power-on, data is restored from non-volatile memory to SRAM. Both operations can be performed under software control.
"Critical mission-critical systems require high-performance memory that can reliably capture data immediately when power is lost," said Sonal Chandrasekhar, director of Cypress's Nonvolatile Products Business Unit. "Cypress' new 1Mb Quad SPI nvSRAM provides Fail-safe data security and throughput of parallel devices with small size and low power consumption. "
Cypress's nvSRAM is based on its SONOS (silicon oxide, silicon oxynitride) embedded non-volatile memory technology, enabling higher density and reduced access time and performance. nvSRAM is the ideal solution for applications requiring high performance and absolute non-volatile data security, such as RAID systems, PLCs, industrial data loggers, computing and network systems, motor drives, routers and switches, avionics, defense Systems and gaming systems.
Cypress is a leader in SONOS process technology and is using the technology in its flagship PSoC mixed-signal array, programmable clock, and other products. SONOS is compatible with standard CMOS technology and has many advantages, including high durability, low power consumption and radiation hardness. SONOS technology is qualified to operate at Cypress's in-house facilities and multiple foundry partner locations. Compared to other magnetic-based non-volatile storage technologies, this technology provides an excellent solution in terms of scalability and manufacturability. Cypress has sold more than 2 billion units that use SONOS processing technology used in nvSRAM.
CY14V101QS 1Mb nvSRAM is sampling now and is expected to be in production in the third quarter of 2015.
