1.
Valid for ambient operating temperature: TA = –40 to 85 °C; VCC = 2.0 to 5.5 V (except where otherwise noted).
2.
STMicroelectronics recommends the RAYOVAC BR1225 or BR1632 (or equivalent)as the battery supply.
3.
After switchover (VSO), VBAT(min) can be 2.0 V for crystal with RS = 40 KΩ.
4.
For rechargeable backup, VBAT(max) may be considered VCC.

1.
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 M41T00. 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.
