Cypress Expands Nonvolatile RAM Portfolio

Cypress Semiconductor Corp. introduced a family of 16Mb nonvolatile Static Random Access Memories (nvSRAMs), including devices with asynchronous parallel and asynchronous Open NAND Flash Interface (ONFI) Standard 1.0 interfaces.

The family extends Cypress’s portfolio to address mission-critical applications such as high-end programmable logic controllers (PLCs), high-speed data/error loggers in storage equipment, networking equipment, avionics systems, and electronic gaming machines.

The 16Mb nvSRAMs are fast high-density asynchronous nonvolatile RAMs, with access times as low as 25ns.

Cypress offers the new devices with an optional integrated Real-Time Clock (RTC), which enables time-stamping of critical data to be logged. nvSRAMs feature infinite read, write and recall cycles, with 20-year data retention at 85°C and 150 years at 65°C. nvSRAM is a solution for applications requiring continuous high-speed reading and writing of data and nonvolatile data security.

“Mission-critical systems require high-performance memories that can capture data instantly and reliably on power loss,” said Rainer Hoehler, senior director of the nonvolatile products business unit, Cypress. “Cypress’s new 16 Mb nvSRAMs deliver absolute data security with the industry’s fastest high-density NVRAM. The ONFI 1.0 interface option also allows customers using NAND controllers to leverage the unmatched performance of our nvSRAMs.”

The 16Mb nvSRAM family is sampling today, with production expected in the third quarter of 2014.

The ONFI 1.0 devices operate on a 3V power supply, 1.8V IO supply, in data bus widths of 8 bits and 16 bits, and are available in a 165-ball FBGA package. The asynchronous parallel devices are offered with and without an RTC, in data bus widths of 8 bits, 16 bits and 32 bits, and at power supply levels of 3V, 5V, and 3V with 1.8V I/O. They are available in 44-pin TSOPII, 48-pin TSOPI, 54-pin TSOPII, and 165-ball FBGA packages.
