Notes:
Load capacitors are integrated within the M41T00. 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.
STMicroelectronics recommends the KDS DT-38 Tuning Fork Type quartz crystal for industrial temperature operations.
KDS can be contacted at 913-491-6825 or http://www.kdsj.co.jp for further information on this crystal type.
