The M41T80 is a Serial RTC (400kHz I2C
bus), an Alarm, and a dedicated 32KHz Output, perfect for battery-operated
applications and microcontrollers which use 32KHz for low-power
modes or as a reference input for clock generators.
The M41T80 is available in production quantities in the Lead-free
SO8 package. |
