By Cypress Semiconductor Corp 80
Cypress adds an interface to its industry-leading nonvolatile RAM (NVRAM) portfolio. The 1 Mb quad SPI nvSRAM meets the data throughput performance of 45 ns, high-speed parallel NVRAM with the reduced pin count of a 16-pin SOIC package and 24-ball BGA package. Cypress nvSRAM solutions reliably store data on power loss without the use of batteries, reducing system cost and maintaining RoHS compliance. The 1 Mb quad SPI nvSRAM is available with an optional integrated real time clock (RTC) and an extended industrial temperature grade of -40˚C to 105˚C. It is the ideal solution for write journaling in RAID storage applications data logging in industrial automation applications and storing critical configuration data in computing and networking applications. Cypress’s quad SPI nvSRAM products utilize high-speed, multiple input/output SPI-compatible bus interfaces. They feature execute-in-place (XIP) functionality and advanced write protection mechanisms, along with dual and quad instructions to enable an aggregate bandwidth of 54 MB/s for read and write operations. These products also provide infinite read/write endurance, one million store cycles on power loss, high-speed reads and writes, nonvolatile data retention and an optional real time clock (RTC). A small external Vcap capacitor is required to complete nonvolatile data transfer upon power loss.
