Notes:
1. Specification for W25Q20BW is preliminary. See preliminary designation at the end of this document.
2. This device has been designed and tested for the specified operation ranges. Proper operation outside
of these levels is not guaranteed. Exposure to absolute maximum ratings may affect device reliability.
Exposure beyond absolute maximum ratings may cause permanent damage.
3. Compliant with JEDEC Standard J-STD-20C for small body Sn-Pb or Pb-free (Green) assembly and
the European directive on restrictions on hazardous substances (RoHS) 2002/95/EU.
4. JEDEC Std JESD22-A114A (C1=100pF, R1=1500 ohms, R2=500 ohms).
