PRODUCTION DATA
PIN | TYPE | DESCRIPTION | |
---|---|---|---|
NO. | NAME | ||
1 | FB0 | Input | Connect this pin to VDD with a pullup resistor. |
2 | AIN0 | Input | Analog input for ADC0. |
3 | NC | — | Not connected. |
4 | NC | — | Not connected. |
5 | NC/SDO | Input/Output | This pin is configurable as SDO. For SDO function, connect this pin to the IO voltage with an external pullup resistor. Leave this pin unconnected if not configured as SDO. |
6 | SCL/SYNC | Output | I2C serial interface clock or SPI chip select input. Connect this pin to the IO voltage using an external pullup resistor. |
7 | A0/SDI | Input | Address configuration input for I2C or serial data input for SPI. In A0 function, connect this pin to VDD, AGND, SDA, or SCL for address configuration. In SDI function, this pin does not need to be pulled up or pulled down. |
8 | SDA/SCLK/PWM | Input/Output | Bidirectional I2C serial data bus or SPI clock input. Connect this pin to the IO voltage using an external pullup resistor. This pin acts as the PWM output for constant power-dissipation control. Pull the VREF/MODE pin high to enable PWM output. |
9 | NC | — | Not connected. |
10 | NC | — | Not connected. |
11 | NC | — | Not connected. |
12 | NC | — | Not connected. |
13 | CAP | Power | External bypass capacitor for the internal LDO. Connect a capacitor (approximately 1.5 μF) between CAP and AGND. |
14 | AGND | Ground | Ground reference point for all circuitry on the device. |
15 | VDD | Power | Supply voltage: 1.8 V to 5.5 V |
16 | VREF/MODE | Input | External reference or interface mode select input. Connect a capacitor (approximately 0.1 μF) between VREF/MODE and AGND. Use a pullup resistor to VDD when the external reference is not used. Make sure that this pin does not ramp up before VDD. In case an external reference is used or when in interface select mode, make sure the reference ramps up after VDD. In interface select mode. Pull this pin low to enable I2C/SPI communication. Pull this pin high to enable PWM output. |
Thermal pad | Thermal Pad | Ground | Connect the thermal pad to AGND. |
