CYPRESS Parallel Nonvolatile SRAM (nvSRAM) P R O D UC T O VE RVI E W A FAST SRAM THAT NEVER LOSES DATA A D VA N TA G E S nvSRAM combines two workhorse CMOS technologies—Cypress’s world leading SRAM HIGH PERFORMANCE INDUSTRY STANDARD INTERFACES technology and best-in-class SONOS nonvolatile technology—into one powerful product line. In your system, the nvSRAM behaves just like a conventional SRAM. The SRAM part of the • Random access IC performs random access read/write at speeds up to 20 ns using standard Async SRAM • Fast async memory timing (20 ns access) signals and timing. But on a power glitch or fail, the intelligence in the chip detects the threat and automatically saves a copy of your SRAM data into nonvolatile memory where it can stay unchanged for over 20 years. On power-up RECALL, the IC returns the data copy back to the SRAM and system operation can continue precisely from where it was left last giving you a fast SRAM that never loses data. The latest high density (16 Mb) nvSRAMs are also available in • ONFI 1.0 • Standard SRAM, ONFI 1.0 compatible packages and pinouts SAVES LIKE A NONVOLATILE MEMORY ONFI 1.0 interface. • Robust technology with 25 years in production The transfer between SRAM and nonvolatile array inside is completely parallel (cell for cell) • 1,000,000 store cycles to nonvolatile elements allowing the STORE operation to complete in 8 ms or less, without user knowledge. The IC family also provides user controlled software STORE and RECALL initiation commands, as well as a user controlled hardware STORE initiation command in most versions. Cypress’s nvSRAMs are offered in industry-standard, RoHS-compliant packaging options such as: TSOP, FBGA, SSOP, and SOIC packages. • 20-year data retention with reliability better than 10 FIT • Full array store on power-down using zero system time NO BATTERIES; COMPLETELY GREEN VALUE-ADDED OPTIONS • Tamper protection with password security • Secure STORE VCC VCAP Power Control 8 Bit Micro-Controller (STORE/RECALL Control) • 105°C and 125°C grade available on demand Non-volatile Elements STORE NO WEAR LEVELING ROUTINES RECALL RTC Optional Hardware Detect Password Optional I/O HSB Software Detect WE,CE,OE nvSRAM block diagram www.cypress.com/nvsram SRAM Core A0-20 D0-31 NO FIRMWARE WAIT STATES FOUND IN OTHER NONVOLATILE SOLUTIONS P R O D UC T O VE RVI E W APPLICATIONS - FOR SHADOW BUFFER, JOURNAL WRITES, ERROR LOGGING, BAT TERY/SUPERCAP REPL ACEMENT IN THE FOLLOWING APPLICATIONS • RAID controllers • Industrial automation • Computing/networking equipment • Data communications • Industrial data logger • Single-board computers • Gaming • Military SONOS NONVOL ATILE TECHNOLOGY Our nonvolatile technology requires very low erase and programming currents, allowing full array STOREs from SRAM to nonvolatile in just 8 ms following each power stop or brownout. Over 1million STORE cycles into SONOS nonvolatile cells can occur without damaging the structure. If power is disrupted 5 times each day, this theoretically allows over 500 years of nonvolatile STORE’s and RECALL’s to your SRAM data. SONOS Nonvolatile Technology is also used in Cypress’s flagship PSoC® (programmable system-on-chip) product, which has shipped over 1 billion devices. AutoSTORE OPERATING MODE AutoSTORE performs STORE operations in the background during power-down, using zero system time. A small external capacitor guarantees sufficient energy to complete STORE when the system power supply drops below the minimum specified operating range. When power is returned, data is automatically RECALL’ed from the nonvolatile elements into the SRAM once the supply reaches operating minimums.
