M41T315Y*, M41T315V, M41T315W
Table 10. Crystal Electrical Characteristics (Externally Supplied)
Note: 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 kou-
hou@kdsj.co.jp or http://www.kdsj.co.jp for further information on this crystal type.
Note: 1. 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.
