Industrial and automotive-edge designs demand memory that works across temperature extremes. Serial NOR Flash is often placed close to the host MCU or FPGA, so its temperature rating matters for system reliability. This guide covers how to source BOYA NOR Flash for wide-temperature applications and what to specify when you request a quote.
1. Temperature-grade basics
- Commercial: usually 0 °C to +70 °C; acceptable for indoor consumer products.
- Industrial: typically −40 °C to +85 °C; the default for outdoor, factory and infrastructure equipment.
- Extended / automotive: −40 °C to +105 °C or +125 °C; requires explicit ordering code and datasheet confirmation.

Frequently asked questions
Are BOYA NOR Flash parts suitable for industrial temperature ranges?
Many BOYA parts are available in industrial temperature grades, but you must confirm the exact ordering code and datasheet revision for the temperature range you need. We list date codes and standard commercial/industrial grades where applicable.
What is the difference between commercial and industrial temperature grade?
Commercial grade is typically 0 °C to +70 °C or −20 °C to +70 °C. Industrial grade is typically −40 °C to +85 °C, sometimes extending to +105 °C or +125 °C. The part number suffix usually encodes the grade.
Do you verify temperature grade before shipping?
We list date codes and traceability information so you can confirm the grade against the manufacturer datasheet and your purchase order. Always specify the required temperature range when requesting a quote.
Which BOYA parts do you stock with recent date codes?
We currently carry BOYA BY25Q and BY25FQ parts with 26+ date codes. Send us the exact part number, temperature grade and quantity for availability.
