AR0230CS: 1/2.7-Inch 2.1 Mp/Full HD Digital Image Sensor

Power-On Reset and Standby Timing

Notes:

1. Xtal settling time is component-dependent, usually taking about 10 – 100 ms.

2. Hard reset time is the minimum time required after power rails are settled. In a circuit where Hard

reset is held down by RC circuit, then the RC time must include the all power rail settle time and

Xtal settle time.

other supplies then sensor may have functionality issues and will experience high current draw on

this supply.
