2.7 Serial Flash (SST26VF032B) (U5)
The RNWF11 Add On Board has an on-board 32-Mb, 2.3-3.6V Serial Flash (SST26VF032B) (U5) memory for storage of data. For more details, refer to the SST26VF032B/SST26VF032BA 2.5V/3.0V 32-Mbit Serial Quad I/O™ (SQI™) Flash Memory (DS20005218).
Note: RNWF11 Add On Board does not use the SST26VF032B’s SQI feature, but supports traditional
Serial Peripheral Interface (SPI) protocol.
