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

Due to the rise of smart vehicles, the automotive electronics requires 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.
In order to make the development and debugging in 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 (now replaced by LA4000 series) and BusFinder series logic analyzer to support the Octal mode NOR Flash for free. These models have high sampling rate and deep memory to log as much data as engineers need.
