BQ32000

This is a class for using the BQ32000 Real Time Clock chip from TI.This is supossed to be pin and code compatible with the most usual DS1307. It is pin compatible as you can see:

On the code side it is almost compatible, with some advanced functions added (trickle charge, calibration) and minor differences in the registers, For example is only capable of generating 1 Hz and 512 Hz square wave.

This library is based on the DS1307 library by Henry Leinen http://developer.mbed.org/users/leihen/code/RTC-DS1307/file/ee81f2c5a706

The trickle charge and calibration are included in the code but not tested against the chip.
