Cypress Semiconductor has 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 104 MHz for the SPI devices and 3,4 MHz for the I²C products, and are 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 elevated reliability and 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. They support SPI operating frequencies up to 104 MHz, SPI modes 0 and 3, infinite read/write and recall cycles with 20 years of data retention. The devices are available in 8-SOIC and 16-SOIC packages.
