Table 7. DC Characteristics
Note: 1. Valid for Ambient Operating Temperature: T
A
= –40 to 85°C; V
CC
= 2.7 to 5.5V (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 back-up, V
BAT
(max) may be considered to be V
CC
.
Table 8. Crystal Electrical Characteristics
Note: 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 con-
tacted 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 32.768kHz crystal of minimum trace
lengths and isolation from RF generating signals should be taken into account.
3. For applications requiring back-up supply operation below 2.5V, R
S
(max) should be considered 40k
