1Mb nvSRAM with quad serial peripheral interface up to 108MHz
New Products
|
Cypress Semiconductor's CY14V101QS 1Mb nonvolatile static random access memory (nvSRAM) comes with a Quad serial peripheral interface (SPI) that works at a clock speed of up to 108 MHz and offers performance exceeding that of a parallel interface (x8 IO width, 45-ns access time) device.
The nvSRAM provides 24MBps 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. Cypress claims its nvSRAM offers lower power consumption by a factor of 5.8 (active) and a factor of 10 (sleep) compared to competitive devices.
