CYPRESS 1-Mbit Quad SPI nvSRAM Eliminate Batteries and Reduce Pin Count While Maintaining High-Speed NVRAM Performance P R O D UC T O VE RVI E W INTRODUCTION F E AT U R E S Cypress, the worldwide leader in NVRAM, introduces its newest nonvolatile SRAM (nvSRAM) HIGH PERFORMANCE solution with a Quad Serial Peripheral Interface (SPI). This solution enables system designers • 10.8 MBps random data throughput to instantly capture and store critical data on power loss without a battery. It also meets the • 54 MBps burst data throughput data throughput performance of high-speed parallel nonvolatile RAM (NVRAM), yet offers the • 108 MHz clock rate reduced pin count of the Quad SPI interface. • Infinite read/write to SRAM HIGH - PERFORM ANCE NVSRA M SOLUTION NO BATTERIES • RoHS compliant • Provides 54 megabytes per second (MBps) burst read/write access time with unlimited write endurance, exceeding the throughput of a x16, 45-ns parallel interface • No battery related mechanical issues • Offers an integrated, high-accuracy, real-time clock option • No end-of-life disposal problems BAT TERY- FREE SOLUTION • No data loss from electrical noise or signal input undershoot • Performs the STORE operations during power-down with AutoSTORE. AutoSTORE uses zero system time with a small external capacitor to complete the STORE during power loss. When power returns to operating minimum, data is automatically RECALL’ed from the nonvolatile elements into the SRAM • No replacement or recharge cycles • No power monitoring required RELIABLE NONVOLATILE MEMORY • 1,000,000 nonvolatile store cycles (on power disruptions only) • Stores data reliably on power loss without batteries, even in magnetic fields, and is RoHS compliant • 20-year data retention • Eliminates the need for an external power-management controller • Full array STORE on power-down in 8 ms using zero system time with a small external capacitor LOW PIN COUNT • Offers a Quad SPI interface with a 108-MHz clock rate • Requires only 6 controller pins connected to the MCU, compared to 29 pins required by a typical parallel SRAM solution • Allows for a simpler design with reduced pin count CYPRESS’ RELIABLE NVSRA M TECHNOLOGY • Allows full array STOREs from SRAM to nonvolatile in just 8 ms following each power loss or brownout • Supports one million STORE cycles into the nonvolatile cells. If power is disrupted five times each day, this would allow over 540 years of nonvolatile STOREs • Provides 20-year data retention www.cypress.com/memory • Software and hardware write protects ADDITIONAL PRODUCT FEATURES • Extended Industrial temp range -40 to 105˚C • Industrial temp range -40 to 85˚C • 1.8 V I/O voltage • 3.0 V supply voltage • Industry-standard 16-SOIC and 24-BGA packages • Integrated real-time clock option • Standard SPI compatibility P R O D UC T O VE RVI E W TARGET APPLICATIONS The 1-Mbit Quad SPI nvSRAM is ideal for write journaling in RAID storage applications, data logging in industrial automation applications and storing critical configuration data in computing and networking applications.
