Cypress unveils advanced flash memory solutions for developers of safety-critical applications
Cypress Semiconductor Corp. announced its Semper NOR Flash memory family that is architected and designed to meet the automotive industry’s ISO 26262 functional safety standard for building fail-safe embedded automotive systems. The family is automotive-qualified, ASIL-B functional safety compliant, and provides endurance and data retention at the extreme temperatures common in automotive and industrial applications. More information on the Semper Flash family is available at www.cypress.com/semper-flash.
Cypress’ EnduraFlex architecture simplifies system design by enabling a Semper Flash device to be divided into multiple partitions, independently optimized for high endurance or long retention. For frequent data writes, a partition can be configured to deliver up to 1.28 million program-erase cycles for 512 Mb density parts and 2.56 million cycles for 1 Gb parts. For code and configuration storage, a partition can be configured to retain data for 25 years.
The Semper Flash family includes AEC-Q100 automotive-qualified devices with an extended temperature range of -40 C to +125 C, supports 1.8-V and 3.0-V operating ranges, and is available in densities of 512 Mb through 4 Gb. The devices are offered with quad serial peripheral interface (SPI), Octal SPI, and HyperBus interfaces. The Octal and HyperBus interface devices are compliant with the JEDEC eXpanded SPI (xSPI) standard for high-speed x8 serial NOR Flash and offer read bandwidth of 400 MBps.
Cypress' 512Mb Semper Flash devices are sampling to lead customers now, with qualified samples available in the fourth quarter of 2018. Volume production of the devices with 24-ball BGA, 16-pin SOIC, and 8-contact WSON packages is expected in the first quarter of 2019.
