General Precautions on Handling of Product
1. Treatment of NC Pins
Note: Do not connect anything to the NC pins.
2. Treatment of Unused Input Pins
Note: Fix all unused input pins to high or low level.
3. Processing before Initialization
Note: When power is first supplied, the product’s state is undefined.
4. Prohibition of Access to Undefined or Reserved Addresses
Note: Access to undefined or reserved addresses is prohibited.
The NC (not connected) pins are either not connected to any of the internal circuitry or are they are used as test
pins or to reduce noise. If something is connected to the NC pins, the operation of the LSI is not guaranteed.
Generally, the input pins of CMOS products are high-impedance input pins. If unused pins are in their open states,
intermediate levels are induced by noise in the vicinity, a pass-through current flows internally, and a malfunction
may occur.
The states of internal circuits are undefined until full power is supplied throughout the chip and a low level is
input on the reset pin. During the period where the states are undefined, the register settings and the output state
of each pin are also undefined. Design your system so that it does not malfunction because of processing while it
is in this undefined state. For those products which have a reset function, reset the LSI immediately after the
power supply has been turned on.
The undefined or reserved addresses may be used to expand functions, or test registers may have been be allocated
to these addresses. Do not access these registers; the system’s operation is not guaranteed if they are accessed.
