Octal SPI NOR Flash

 Octal mode (8 data I/O) Serial NOR Flash

Due to the rise of smart vehicles, automotive electronics require NOR Flash for safer storage and faster data transmitting in-vehicle systems. Various NOR Flash manufacturers have launched high-speed Octal NOR Flash to satisfy needs.
To make development and debugging in the automotive industry possible, the upgrade of Octal mode NOR Flash bus decode and trigger for our logic analyzers seems inevitable. Hence, we have upgraded our LA3000+ series, and BusFinder series logic analyzer to support the Octal mode NOR Flash for free. These models have a high sampling rate and deep memory to log as much data as engineers need.

Support Trigger、Protocol Analyzer、Protocol decodes (According to the optional model)
