Signal descriptions
2.12
V
CC
supply voltage (2.7 V to 3.6 V)
V
CC
provides the power supply for all operations (read, program and erase).
The command interface is disabled when the V
CC
supply voltage is less than the lockout
voltage, V
LKO
. This prevents bus write operations from accidentally damaging the data
during power-up, power-down and power surges. If the program/erase controller is
programming or erasing during this time then the operation aborts and the memory contents
being altered will be invalid.
A 0.1 µF capacitor should be connected between the V
CC
supply voltage pin and the V
SS
ground pin to decouple the current surges from the power supply. The PCB track widths
must be sufficient to carry the currents required during program and erase operations, I
CC3
.
2.13
V
SS
ground
V
SS
is the reference for all voltage measurements. The device features two V
SS
pins which
must be both connected to the system ground.
