The Semper Flash family is the first memory designed to meet the automotive industry’s standard for reliability in the production of intrinsically safe embedded automotive systems, ISO 26262, explains Rainer Hoehler, Vice President and General Manager of Cypress’ Flash Business Unit.
The Semper family is automotive-qualified, complies with ASIL-B for functional reliability and offers superior rewritability and data retention at the extreme temperatures frequently encountered in automotive and industrial applications.
The Cypress EnduraFlex architecture simplifies system development by dividing a Semper Flash device into multiple partitions that can be individually optimized for high rewritability or long data retention. For frequent writes, a partition can be configured to reach up to 1.28 million programming erase cycles on 512 Mb and 2.56 million at 1 Gb devices. A low access frequency partition can be configured to store code and configuration data, allowing data retention for 25 years.
The Semper Flash family comprises AEC-Q100 automotive-qualified devices with an extended temperature range from -40 °C to +125 °C, supports operating voltages of 1.8 and 3.0 V and is available in densities from 512 Mb to 4 Gb. The devices are offered with Quad SPI interface (Quad Serial Peripheral Interface), Octal SPI interface and HyperBus™ interface. The versions with Octal and HyperBus interface comply with the JEDEC eXpanded SPI (xSPI) standard for x8 serial high-speed NOR flash and offer bandwidths of 400 MBps.
