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
