1. Externally supplied if using the QFN16 or SO8 package. STMicroelectronics recommends the Citizen CFS-
145 (1.5x5mm) and the KDS DT-38 (3x8mm) for thru-hole, or the KDS DMX-26S (3.2x8mm) for surface-
mount, tuning fork-type quartz crystals.
KDS can be contacted at kouhou@kdsj.co.jp or http://www.kdsj.co.jp.
Citizen can be contacted at csd@citizen-america.com or http://www.citizencrystal.com.
2. Load capacitors are integrated within the M41T8x. Circuit board layout considerations for the 32.768kHz
crystal of minimum trace lengths and isolation from RF generating signals should be taken into account.
3. Guaranteed by design.
