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.
Table 6. Crystal Electrical Characteristics
Note: 1. These values are externally supplied. 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 kou-
hou@kdsj.co.jp or http://www.kdsj.co.jp for further information on this crystal type.
2. Load capacitors are integrated within the M41T0. Circuit board layout considerations for the 32.768kHz crystal of minimum trace
lengths and isolation from RF generating signals should be taken into account.
