Flash memory suits mission critical applications
Semper NOR flash memory products from Cypress Semiconductor are now available at distributor RS Components.
The devices are designed to support automotive, communication, and industrial applications.
emper achieves the ISO 26262 automotive functional safety standard for electronics in vehicles, and is compliant with IEC 61508 for industrial applications.
It is said to be the industry's first NOR flash memory to be Automotive Safety Integrity LevelASIL-B compliant and ASIL-Dready.
Next-generation 5G wireless communications, offering more than 20 times the bandwidth of current networks, will enablenew “always connected” applications inindustrial IoT, connected and autonomous vehicles, and portable medical devices.
To deliver high reliability, bandwidth and functionality, the SoCs and FPGAs powering 5G radios and base stations will require increasingly vast amounts of configuration and boot code data to be stored and accessed quickly.
Semper NOR flash addresses these needs by offering densities up to 4Gbit and JEDEC xSPI compatible interfaces, extending the bandwidth up to 400MBps.
The devices offer densities from 256Mbit up to 4Gbit,withreliability, performance and 10-yearlongevity required for mission critical applications. Semper NOR devices are compatible with multiple SoCs and FPGAs.
There are a range of low-pin-count serial interface options, including legacy SPI, DDR Quad SPI with data rates up to 102MBps, and JEDEC xSPI compatible HyperBus and Octal interfaces with up to 400MBps data rates.
Using XIP (eXecute In Place), programs can execute directly from flash memory, allowing high-data-rate Quad SPItransactions to exceed the performance of parallel orasynchronous NOR devices.
Cypress’s EnduraFlex architecture allows system designers to customise Semper devices to suit specificapplications, defining partitions to provide high memory endurance of up to 2.5 million cycles or long data retention of up to 25 years.
Semper supports SafeBoot, to detect device initialisation failures and configuration corruption.
ECC (single error correction and double error detection) is supported on the memory array, with CRC protection for both interface and data.
These flash memories are AEC-Q100 qualified, and proven at extreme temperatures from –40°C to +125°C.
Operating voltage is 3.0V or 1.8V. Packaging options include 24-contact BGA, 8-contact WSON and 16-pin SOIC.
Cypress Semper NOR flash memory products are now available from RS in the EMEA and Asia Pacific regions.
