Cypress expands serial nvSRAM portfolio with I2C and SPI devices
The new Cypress memory devices deliver operating frequencies up to 104 MHZ for the SPI devices (3.4 MHz 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.
The nvSRAMs are manufactured on its S8 0.13-micron SONOS (Silicon Oxide Nitride Oxide Silicon) embedded non-volatile memory technology, enabling high reliability and improved performance. nvSRAMs the technology of choice solutions for applications requiring absolute non-volatile data security such as electronic smart meters, PLCs, motor drives, electronic data recorders in automobiles, RAID systems as well as medical and data communication systems, Cypress said.
The serial nvSRAM family includes 1-Mbit, 512-Kbit, 256-Kbit and 64-Kbit devices in multiple configurations. These devices feature an industry-first SPI operating frequency of up to 104 MHz, 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.
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 volume production beginning in April.
