PIN NAME
FUNCTION
11 SCL
I2C bus SCL pin. Because surge
breakdown voltage is low, take external
countermeasure if necessary.
INTERFACE
TA1226N
I / O SIGNAL
12 SDA
I2C bus SDA pin. Because surge
breakdown voltage is low, take external
countermeasure if necessary. When Vcc
voltage is 3.2V or more, power-on reset is
applied.
13 Digital GND Logic circuit GND pin.
14 OSC
Used to connect filter for obtaining 4MHz.
Using 4-MHz oscillation, automatically
adjusts built-in delay line.

Automatic
15 filter
adjustment
Used to connect filter which automatically
adjusts delay time of IC built-in delay line.
Directly connecting external pull-up resistor
increases peak frequency.
Pulling down decreases peak frequency.
DC
5.9V (Typical)
