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.
