Parameter(1)(2)(3)
1.
These values are 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 kouhou@kdsj.co.jp or
http://www.kdsj.co.jp for further information on this crystal type.
2.
Load capacitors are integrated within the M41T11. 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.
All SNAPHAT
battery:crystal tops meet these specifications.
