3.2.5

RTC

An optional RTC can be equipped on the TQMaX4XxL. The connection is realized as follows:

•

The RTC can be supplied from the base board via V_RTC_IN. V_RTC_IN = 2.0 V to 5.5V

•

RTC_INT# and RTC_CLKOUT is accessible at the LGA pads.

•

RTC_CLKOUT is only activated as soon as the TQMaX4XxL is supplied with V_5V_IN.

•

I2C is connected via I2C0 (I²C addresses are described in chapter 3.2.8.7)

Figure 9: Block diagram RTC

Note: Equipping the base board

The RTC is supplied internally by a LDO (1.8V) via V_RTC_IN. This allows the user an easy use of Gold-

Caps or Coin cells on the main board.
