1Mb nvSRAM targets industrial automation, networking apps

Cypress Semiconductor Corp. has uncloaked a 1Mb non-volatile static random access memory (nvSRAM) with a quad serial peripheral interface (SPI), which enables the device to exceed the data throughput of larger parallel interface devices with a smaller footprint. According to the company, the nvSRAM ensures high-throughput data capture in event of a power loss without batteries for RAID storage, industrial automation, computing and networking applications.

The CY14V101QS 1Mb nvSRAM with Quad SPI interface works at a clock speed of up to 108MHz and offers performance exceeding that of a parallel interface (x8 IO width, 45ns access time) device. The nvSRAM provides 24MB/s random read/write access time with unlimited write endurance, and 20-year data retention. With its reduced I/O width, it offers reduced pin count and board footprint in a 16-pin SOIC package and 24-ball BGA package.

The device also includes an optional integrated real-time clock (RTC) with ±50ppm uncalibrated accuracy. The nvSRAM offers lower power consumption by a factor of 5.8 (active) and a factor of 10 (sleep) compared to competitive devices.
