Introduction
Thank you for your interest in the CY14NVSRAMKIT-001 nvSRAM Development Kit (DVK). The kit
(shield) is designed as an easy-to-use and inexpensive development kit, showcasing the features of
Cypress high-speed, parallel access (asynchronous interface), nonvolatile SRAM (nvSRAM). This
kit works in conjunction with the SK-FM4-U120-9B560 FM4 MCU Evaluation Board, a starter kit for
ARM
®
Cortex
®
-M4-based devices. You will need both kits to demonstrate the operation described in
this guide. This board features a 16-Mbit parallel nvSRAM with real time clock (RTC) and associated
circuits, super capacitor for RTC backup in the absence of the VCC supply, FM4 mounting headers,
and test pins. This kit supports 3.3-V power supply.
Cypress nvSRAM is built on 130-nm technology and combines a silicon-oxide-nitride-oxide-silicon
(SONOS) nonvolatile data storage cell with a high-performance SRAM cell. The parallel nvSRAMs
provide the fastest nonvolatile writes at bus speed. They do not have any write delays and data is
instantly nonvolatile. Because of fast write speeds, parallel nvSRAMs need to be active for short
periods, yielding low energy consumption. Endurance is unlimited for writing into SRAM. The SRAM
data is automatically saved to nonvolatile memory upon power down.
