Semper achieves the ISO 26262 automotive functional safety standard for electronics in vehicles, and is compliant with IEC 61508 for industrial applications. Semper is the industry's first NOR flash memory to be Automotive Safety Integrity Level ASIL-B compliant and ASIL-D ready, Semper NOR flash offers densities up to 4Gbit and JEDEC xSPI compatible interfaces, extending the bandwidth up to 400MBps. Semper NOR flash offers densities from 256Mbit up to 4Gbit, with reliability, performance and 10-year longevity required for mission critical applications. The devices are compatible with multiple SoCs and FPGAs. The chips come in 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 SPI transactions to exceed the performance of parallel or asynchronous NOR devices. 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. The NOR flash memories are AEC-Q100 qualified, and proven at extreme temperatures from –40°C to +125°C and operate from 3.0V or 1.8V. Packaging options include 24-contact BGA, 8-contact WSON and 16-pin SOIC.
