Notes: Load capacitors are internally supplied with the MK41T56. 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.
SGS-THOMSON recommends the ECS-.327-12.5-8SP-2 quartz crystal for industrial temperature operations. ESC Inc. can be
contacted at 800-237-1041 or 913-782-7787 for further information on this crystal type.
