1.
Externally supplied if using the QFN16 package. STMicroelectronics recommends the Citizen CFS-145
(1.5 x 5 mm) and the KDS DT-38 (3 x 8 mm) for thru-hole, or the KDS DMX-26S (3.2 x 8 mm) or Micro
Crystal MS3V-T1R (1.5 x 5 mm) for surface-mount, tuning fork-type quartz crystals. For contact
information, see Section 8: References on page 47.
2.
Load capacitors are integrated within the M41T93. 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.
