Adds integrated real-time clock capability
Cypress Semiconductor has launched a new 1-Mbit Serial non-volatile Static Random Access Memory (nvSRAM) family and new 4-Mbit and 8-Mbit nvSRAMs with an integrated real-time clock (RTC).
The company said that its nvSRAMs are manufactured on S8 0.13-micron SONOS (Silicon Oxide Nitride Oxide Silicon) embedded non-volatile memory technology. nvSRAMs are suitable for applications requiring non-volatile data security such as RAID systems, industrial control and automation, single board computers, POS terminals, eMetering, automotive, medical and data communication systems.
According to Cypress, the serial nvSRAM family includes 1-Mbit devices in multiple configurations with an SPI interface. The serial nvSRAMs feature operating frequencies up to 40MHz. The new 4-Mbit and 8-Mbit nvSRAMs integrate an RTC that enables time stamping of critical data for back-up and also features a programmable alarm function and watchdog timer.
The company claims that its nvSRAMs offer fast non-volatile data storage without batteries. 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.
Jithender Majjiga, senior director of the non-volatile products business unit at Cypress, said: “Our new serial family extends Cypress’s industry-leading nvSRAM portfolio to address applications that require high-endurance memories in industry-standard, low-pin count packages. Likewise, integrating a real-time clock in our nvSRAMs enables our portfolio to cover applications traditionally served by BBSRAMs.”
