CCS811 LGA Pin Assignment
| Pin No. | Pin Name | Description |
|---|---|---|
| 1 | ADDR | Single address select bit to allow alternate address to be selected • When ADDR is low the 7 bit I²C address is decimal 90 / hex 0x5A • When ADDR is high the 7 bit I²C address is decimal 91 / hex 0x5B. |
| 2 | nRESET | nRESET is an active low input and is pulled up to V DD by default. nRESET is optional but external 4.7KΩ pull-up and/or decoupling of the nRESET pin may be necessary to avoid erroneous noise-induced resets. |
| 3 | nINT | nINT is an active low optional output. It is pulled low by the CCS811 to indicate end of measurement or a set threshold value has been triggered. |
| 4 | PWM | Heater driver PWMoutput. Pins 4 and 5 must be connected together. |
| 5 | Sense | Heater current sense. Pins 4 and 5 must be connected together. |
| 6 | V DD | Supply voltage |
| 7 | nWAKE | nWAKE is an active low input and should be asserted by the host prior to an I²C transaction and held low throughout. |
| 8 | AUX | Optional AUX pin which can be used for ambient temperature sensing with an external NTC resistor. If not used leave unconnected. |
| 9 | SDA | SDA pin is used for I²C data. Should be pulled up to V DD with a resistor |
| 10 | SCL | SCL pin is used for I²C clock. Should be pulled up to V DD with a resistor |
| EP | Exposed Pad | Connect to ground |

-
The minimum supply voltage V DD is 1.8V and should not drop below this value for reliable device operation.
Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only. Functional operation of the device at these or any other conditions beyond those indicated under Electrical Characteristics is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability
