Description
ICE control.
ICE control.
ICE control.
ICE control.
Analog input pin. This signal goes to a programmable
comparator and is used to sense the value of an external
voltage.
Input pin for use in programming security fuse. It should be
connected to ground when not in use.
Test pin, should be connected to ground
Special output driver, programmable pull-down current to
drive LED. May also be used as an input.
V
at each VDD pin.
No connect.
General ground supply pins for all IO and logic circuits.
Reset input, positive assertion. Resets logic and registers
to default condition. Note: to insure proper reset operation
after V
activation of the ON/OFF switch, external reset circuitry
must generate a proper reset signal to the 73S1210F. This
can be accomplished via a simple RC network.
DD
supply output pin. A 0.1µF capacitor is recommended
DD
is turned on by application of V
