AS7263 − Detailed Description

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

AS7263.

Indicator LED

The LED, connected to pin LED_IND, can be used to indicate

programming progress of the device.

While programming the AS7263 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.

Electronic Shutter with LED_DRV Driver Control

There are two LED driver outputs that can be used to control

up to 2 LEDs. This will allow different wavelength light sources

to be used in the same system. The LED output sink currents are

programmable and can drive external LED sources: LED_IND

from 1mA, 2mA, 4mA and 8mA and LED_DRV from 12.5mA,

25mA, 50mA and 100mA. The sources can be turned off and on

via I²C registers control or AT commands and provides the

device with an electronic shutter.
