1.
These values are externally supplied for 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. For contact information on this crystal type, see Section 8:
2.
Load capacitors are integrated within the M41T56. 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.
