AS7262 − Detailed Description
RC Oscillator
The timing generation circuit consists of an on-chip 16MHz,
temperature compensated oscillator, which provides the
master clock for the AS7262.
Temperature Sensor
The temperature sensor is constantly measuring the on-chip
temperature and enables temperature compensation
procedures.
Reset
Pulling down the RESN pin for longer than 100ms resets the
AS7262.

Indicator LED
The LED, connected to pin LED_IND, can be used to indicate
programming progress of the device.
While programming the AS7262 via the external SD card the
indicator LED starts flashing (500ms pulses). When
programming is completed the indicator LED is switched off.
The LED (LED0) can be turned ON/OFF via AT commands or via
I²C register control. The LED sink current is programmable from
1mA, 2mA, 4mA and 8mA.
