AK4160 AKM [Asahi Kasei Microsystems], AK4160 Datasheet - Page 4

• Manufacturer Part Number: AK4160
• Description: 16-channel Capacitive Touch Sensor IC
• Manufacturer: AKM [Asahi Kasei Microsystems]

Note 1. A (Analog terminal), D (Digital terminal), GND (Ground), PWR (Power)
Note 2. I (Input terminal), O (Output terminal)
Note 3. All digital input pins ( AD0, AD1, SCL, SDA) must not be allowed to float.
Note 4. When GPIO pins (GPIOA ~ GPIOC, GPIO0 ~ GPIO7) are configured to digital inputs without internal pull
Note 5. Outputs “L” after releasing a reset.
■
The unused I/O pins must be connected appropriately.
