FM25V40, 4-Mbit (512K x 8) Serial (SPI) F-RAM
CS Input Chip Select.
This active LOW input activates the device.
When HIGH, the device enters low-power standby mode, ignores other inputs, and the output is tristated.
When LOW, the device internally activates the SCK signal.
A falling edge on CS must occur before every opcode.
SCK SI[1] SO[
