16-Mbit parallel nvSRAMs and Synchronous NAND interfaces
September 12, 2012 // Julien Happich
Cypress Semiconductor introduced a family of 16-Mbit non-volatile static random access memories (nvSRAMs), including devices with synchronous NAND flash memory interfaces.
The family marks the industry's first non-volatile SRAM memory that can interface directly with Open NAND Flash Interface (ONFI) and Toggle NAND bus controllers, claims the manufacturer. The 16-Mbit family extends Cypress's nvSRAM portfolio to address Solid State Drives (SSD) for enterprise systems, high-end Programmable Logic Controllers (PLC), high-speed data/error loggers in storage, and networking equipment. The 16-Mbit nvSRAMs offer access times as low as 25ns, making them the fastest asynchronous non-volatile RAMs on the market. The new devices are offered with an optional integrated Real-Time Clock (RTC) that is not available in competing solutions.
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 (100MHz) and the ONFI 3.0 NV-DDR2 interface (200MHz). 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.

Internet of Things (IoT) manufacturer Ciseco has launched the Raspberry Pi ‘Wireless Inventors Kit’ (RasWIK), featuring 88 pieces to provide everything a Pi owner needs to follow a series of step-by-step projects or to create their own wireless devices, without the need for configuration or even writing code.
RasWIK has been designed to be highly accessible, demystifying the dark art of wireless and enabling anyone with basic computing skills to begin building wireless devices with a Raspberry Pi. You can create anything from a simple traffic light, to a battery monitor, or even a temperature gauge that sends data to the Xively IoT cloud so billions can access the data.This month, Ciseco is giving away twelve Raspberry Pi Wireless Inventors kits, worth £49.99 each for EETimes Europe's readers to win.
And the winners are...
In our previous reader offer, Farsens was giving away five kits for EEtimes Europe readers to evaluate its FenixVortex, Kineo and X1 wireless, battery free sensor tags.
Lucky winners include Mr A. Neil from the UK, Mr. E. Delvaux from Belgium, Mr Lengal from the Czech Republic, Mr H. Bijlsma from the Netherlands, and Mr G. Pfaff from Germany. All should be receiving their packages soon. Lets wish them some interesting findings with their projects.
