The memory is accessed via a simple Sequential Read Serial Peripheral Interface (SPI) compatible serial bus. High Reliability: The bus signals required are a clock input (SCK) plus - Endurance: >1M erase/write cycles separate data in (SI) and data out (SO) lines. Access to - Data retention: >200 years ) the device is controlled through a Chip Select (CS - ESD protection: >4000V input. Temperature Ranges Supported: - Industrial (I): -40 Cto +85C Communication to the device can be paused via the - Extended (E): -40C to +125C hold pin (HOLD). While the device is paused, RoHS Compliant transitions on its inputs will be ignored, with the Automotive AEC-Q100 Qualified exception of Chip Select, allowing the host to service higher priority interrupts.
