The DS32kHz is packaged in a small 36-pin SMD, utilizing ball grid array (BGA) technology, with
dimensions 0.400 inches wide, 0.450 inches long, and 0.180 inches high. Also available in a 14-pin DIP
module.
The additional board space required is negligible in most applications and therefore the recommended
land pattern layout should be implemented on all new designs and future board revisions to satisfy
applications requiring better timekeeping accuracy

OPERATION
The DS32kHz module contains a crystal and an IC. While powered, the DS32kHz peridocially measures
the temperature and adjusts the crystal load to compensate.
The DS32kHz is designed to operate in two modes. In the two supply mode, a comparitor circuit,
