Functions

Apply 5 V ± 0.5 V to Vcc, and 0 V to Vss.

Connect this pin to Vss.

Connect this pin to Vss via a resistor of 10 kΩ to 100 kΩ.

The reset input pin.

Connect a ceramic oscillator between the XIN and XOUT pins, or input an external

clock from the XIN pin with the XOUT pin left open.

Connect AVcc to Vcc, and AVss to Vss.

Input an arbitrary level within the range of VSS–VCC. (This is not used in the flash memory serial I/O mode.)

Input “H” or “L”, or leave them open. (This is not used in the flash memory serial I/O mode.)

Input “H” or “L”, or leave them open. (This is not used in the flash memory serial I/O mode.)

This is an input pin for a serial clock.

This is an I/O pin for serial data. Connect this pin to VCC via a resistor (about 1 kΩ).

This is an output pin for the BUSY signal.

Input “H”.

Input “H” or “L”, or leave them open. (This is not used in the flash memory serial I/O mode.)

Input “H” or “L”, or leave them open. (This is not used in the flash memory serial I/O mode.)

Input “H” or “L”, or leave them open. (This is not used in the flash memory serial I/O mode.)

Connect this pin to the filter circuit, or leave this pin open. (This is not used in the flash

memory serial I/O mode.)
