Table 6. DC Characteristics
(TA = –40 to 85 °C; VCC = 2.0V to 5.5V)
Note: 1. STMicroelectronics recommends the RAYOVAC BR1225 or BR1632 (or equivalent) as the battery supply.
Table 7. Power Down/Up Trip Points DC Characteristics (1)
(TA = –40 to 85 °C)
Note: 1. All voltages referenced to VSS.
2. Switch-over and deselect point.
Table 8. Crystal Electrical Characteristics
(Externally Supplied if using the SO8 package)
Note: Load capacitors are integrated within the M41T11. 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.
STMicroelectronics recommends the KDS DT-38 Tuning Fork Type (thru-hole) or DMX-26 (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.
All SNAPHAT battery/crystal tops meet these specifications.
