1.
These values are externally supplied. 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 kouhou@kdsj.co.jp or http://www.kdsj.co.jp for further information on this crystal type.
2.
Load capacitors are integrated within the M41T0. 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.
3.
RS = 40 kΩ when VCC ≤ 2.5 V.
