1. Valid for ambient operating temperature: TA = –40 to 85°C; VCC = 2.7 to 5.5 V (except where noted).
2. For FT/OUT pin (open drain).
3. STMicroelectronics recommends the RAYOVAC BR1225 or BR1632 (or equivalent) as the battery supply.
4. For rechargeable backup, VBAT (max) may be considered to be 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 M41T00S. 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.
3. For applications requiring backup supply operation below 2.5 V, RS (max) should be considered 40 kΩ.
