6.3V
For 3.3V FLASH use 3.3V latches also. For 5V FLASH use either 5V or
3.3V latch since the FLASH usually have TTL compatible inputs.
Recommended FLASH speed grade is 90ns.
Notes:
To reduce the power consumption, we recommend using 3.3V FLASH
and LATCH.
Note on Ferrites:
Ferrites should have a current rating of 150mA minimum.
Ferrites should have a current rating of 150mA minimum.
Some examples are:
