Cypress introduces 16-Mb NV SRAMS
Julien Happich9/21/2012 3:29 PM EDT
Cypress Semiconductor has introduced a family of 16-Mb non-volatile SRAMS (nvSRAMs), including devices with synchronous NAND flash memory interfaces.
The family marks the industry's first nvSRAM memory that can interface directly with Open NAND Flash Interface (ONFI) and Toggle NAND bus controllers, claims the manufacturer. The 16-Mb family extends Cypress's nvSRAM portfolio to address SSDs for enterprise systems, high-end programmable logic controllers (PLCs), high-speed data/error loggers in storage, and networking equipment. The 16-Mb nvSRAMs offer access times as low as 25 ns. The new devices are offered with an optional integrated real-time clock (RTC).
The RTC enables time-stamping of critical data to be logged. Cypress nvSRAMs feature infinite read, write, and recall cycles, with 20-year data retention, making them suitable for applications requiring continuous high-speed writing of data and absolute non-volatile data security.
The ONFI NAND interface nvSRAM supports the ONFI 3.0 NV-DDR interface (100 MHz) and the ONFI 3.0 NV-DDR2 interface (200 MHz). The Toggle NAND interface nvSRAM is compatible with Toggle 2.0 NAND controllers for DDR operation at 200MHz. Both ONFI and Toggle versions support single-channel operations in x8 and x16 data bus widths, and dual- and quad-channel operations in x8 bit data bus width, which allows operations of up to 400 million transactions per second.
The CY14V116Fx ONFI and Toggle NAND devices operate on a 3 V core with 1.8 V IO supply. Both the asynchronous devices with and without RTC are offered in data bus widths of 8 bits, 16 bits, and 32 bits at power-supply levels of 2.5 V, 3 V, and 5 V. They are available in 44-pin TSOPII, 48-pin TSOPI, and 165-ball FBGA packages.
