‘Industry’s first’ SPIs with operating frequency up to 104MHz
1 min read
Cypress Semiconductor has unveiled new serial non volatile static random access memories (nvSRAMs) with I2C and SPI interfaces for metering, industrial and automotive applications requiring absolute non volatile data security.
According to Cypress, the new devices are optimised to deliver the industry's first operating frequencies up to 104MHZ for the SPI devices and up to 3.4MHz for the I2C products. They are offered with an optional integrated real time clock to enable time stamping of critical data to be backed up.
The units are manufactured on the company's S8 0.13micron Silicon Oxide Nitride Oxide Silicon embedded non volatile memory technology, which it claims enables superior reliability and improved performance. They feature SPI Modes 0 and 3, infinite read/write and recall cycles with 20 years of data retention and are available in 1, 512, 256 and 64Kbit. In addition, they are available in industry standard small footprint 8 and 16-SOIC packages.
"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."
