Cypress Expands Serial nvSRAM Portfolio With New I2C And Second-Generation SPI Devices in Densities from 64kb to 1Mb


Leveraging 0.13-Micron SONOS Used in Flagship PSoC products, Cypress nvSRAMs Offer Superior Performance and Reliability for Metering, Industrial and Automotive Applications

SAN JOSE, Calif. - Cypress Semiconductor Corp. (Nasdaq: CY) today introduced new serial non-volatile Static Random Access Memories (nvSRAMs) with I2C and SPI interfaces popular with metering, industrial and automotive applications. The new devices deliver operating frequencies up to 104MHZ for the SPI devices (3.4MHz for the I2C products) and are also offered with an optional integrated Real-Time Clock (RTC) that enables time-stamping of critical data to be backed-up.

Cypress’s nvSRAMs are manufactured on its S8™ 0.13-micron SONOS (Silicon Oxide Nitride Oxide Silicon) embedded non-volatile memory technology, enabling superior reliability and improved performance. nvSRAMs are ideal solutions for applications requiring absolute non-volatile data security such as Electronic Smart Meters, PLCs, Motor Drives, Electronic Data Recorders in Automobiles, RAID systems, Medical and Data Communication Systems.

The new Serial nvSRAM family includes 1-Mbit, 512-Kbit, 256-Kbit and 64-Kbit devices in multiple configurations. These devices feature superior performance with an industry-first SPI operating frequency up to 104MHz, SPI Modes 0 and 3, infinite READ/WRITE and RECALL cycles with 20 years of data retention. These devices are available in industry-standard small footprint 8-SOIC and 16-SOIC packages. For more information about Cypress’s portfolio of nvSRAM products, visit

“Our customers have encouraged us to add these serial interface products to our existing parallel nvSRAM product portfolio because nvSRAM is a viable, high-volume CMOS based solution,” said Jithender Majjiga, Senior Director of the Non-Volatile Products Business Unit at Cypress. “Competing solutions tend to use non-standard process technologies and struggle to maintain a consistent source of supply. With a robust flexible supply chain and high quality manufacturing, Cypress is well positioned to address the high volume serial market.”

A leader in SONOS process technology, Cypress is using the S8 technology in next generation PSoC® mixed-signal arrays, programmable clocks and other products. SONOS is compatible with standard CMOS technologies and offers numerous advantages including high endurance, low power, and radiation hardness. Cypress’s S8™ 0.13-micron SONOS technology is qualified to run in its internal fab and in multiple foundry partner locations. SONOS technology provides a superior solution in terms of scalability and manufacturability compared to other magnetic or ferroelectric based non-volatile memory technologies.

Cypress’s Serial nvSRAMs are available in I2C (1-Mbit: CY14B101J) and SPI (1-Mbit: CY14B101QA) interfaces in small footprint 8-SOIC and 16-SOIC packages. The devices are also available in 512-Kbit, 256-Kbit and 64-Kbit densities and with an optional integrated Real-Time Clock. The devices are currently sampling with high volume production beginning in April. For a high-resolution photo of the new nvSRAMs, visit

About Cypress nvSRAMs
Cypress’s nvSRAMs use charge stored on an external capacitor instead of a battery, making the devices compatible with standard PCB assembly processes. Cypress’s nvSRAMs are ROHS-compliant and directly replace SRAM, battery-backed SRAM (BBSRAM) and EEPROM devices, offering fast non-volatile data storage. Data transfers from the SRAM to the device’s non-volatile elements take place automatically at power down. On power up, data is restored to the SRAM from the non-volatile memory. In Metering, Industrial, Automotive and RAID applications, nvSRAMs offer high-speed data transfer while ensuring data integrity in case of power outages, without the need for a battery.
