Digital negative power supply (3.0 V spec.)
Bias output for LCD driver (1.5 V spec.)

Bias output for LCD driver (–4.5 V)

For connection to capacitors that generate bias for the
LCD driver

Negative power supply voltage pin for internal logic
(An internally generated constant voltage is present at this pin.)

Clock oscillation pins:
Either a crystal (32.768 kHz) and a capacitor (10 to 30 pF)
are connected to these pins or a resistor (1 MW) is.

Input pins for test

System reset input pin :
Setting this pin to "H" level puts this device into a reset state.
Then, setting this pin to "L" level starts executing an instruction
from address 000H.
This pin is internally connected to V

Notes for Mounting the Surface Mount Type Package

The SOP, QFP, TSOP, SOJ, QFJ (PLCC), SHP and BGA are surface mount type packages, which
are very susceptible to heat in reflow mounting and humidity absorbed in storage.
Therefore, before you perform reflow mounting, contact Oki’s responsible sales person for the
product name, package name, pin number, package code and desired mounting conditions
(reflow method, temperature and times).
