Figure 2-1. Pinouts
HOLD
Hold: The HOLD pin is used to temporarily pause serial communication without
deselecting or resetting the device. While the HOLD pin is asserted, transitions on
the SCK pin and data on the SI pin will be ignored, and the SO pin will be in a
high-impedance state.
The CS pin must be asserted, and the SCK pin must be in the low state in order for
a Hold condition to start. A Hold condition pauses serial communication only and
does not have an effect on internally self-timed operations such as a program or
erase cycle. See “Hold” on page 46 for additional details on the Hold operation.
The HOLD pin is internally pulled-high and may be left floating if the Hold function
will not be used. However, it is recommended that the HOLD pin also be externally
connected to VCC whenever possible.
Low
Input
VCC
Device Power Supply: The VCC pin is used to supply the source voltage to the
device.
Operations at invalid VCC voltages may produce spurious results and should not be
attempted.
Power
GND
Ground: The ground reference for the power supply. GND should be connected to
the system ground.
