Table 5. DC Characteristics
Note: 1. Valid for Ambient Operating Temperature: T
A
= –40 to 85°C; V
CC
= 2.0 to 5.5V (except where noted).
2. At 25°C.
3. For IRQ/FT/OUT, RST, and 32kHz pins (Open Drain)
Table 6. 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 M41T80. 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.
