Parameter(1)(2)
1.
These values are externally supplied. STMicroelectronics recommends the KDS DT-38:
1TA/1TC252E127, Tuning Fork Type (thruhole) 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 M41T315Y/V/W. Circuit board layout considerations for the
32.768kHz crystal of minimum trace lengths and isolation from RF generating signals should be taken into
account.
