Note: 1. These devices are only available in OTP versions.
2. The RTC can be used as the system clock giving a typical operating current of 20mA at 3V.
3. The standby current is 1mA at 3V with the RTC still running.
4. The LED driver output pins can also be used to drive LCDs with a 28´4, 1/2 bias drive type.
