Table 7. DC Characteristics
Note: 1. Valid for Ambient Operating Temperature: TA = –40 to 85°C; VCC = 2.0 to 5.5V (except where noted).
2. STMicroelectronics recommends the RAYOVAC BR1225 or BR1632 (or equivalent) as the battery supply.
3. After switchover (VSO), VBAT(min) can be 2.0V for crystal with RS = 40K.
4. For rechargeable back-up, VBAT(max) may be considered VCC.
Table 8. Crystal Electrical Characteristics
Note: 1. These values are 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 M41T11. 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. All SNAPHAT battery/crystal tops meet these specifications.
