1.

Externally supplied if using the SO8 package. STMicroelectronics recommends the KDS DT-38: 1TA/1TC252E127, Tuning

Fork Type (thru-hole) or the DMX-26S: 1TJS125FH2A212, (SMD) quartz crystal for industrial temperature operations. KDS

can be contacted at http://www.kds.info/index_en.htm for further information on this crystal type.

2.

Load capacitors are integrated within the M41T00AUD. Circuit board layout considerations for the 32.768 kHz crystal of

minimum trace lengths and isolation from RF generating signals should be taken into account.
