Table 5. DC Characteristics
Note: 1. Valid for Ambient Operating Temperature: TA = –40 to 85°C; VCC = 4.5 to 5.5V (except where noted).
2. STMicroelectronics recommends the RAYOVAC BR1225 or BR1632 (or equivalent) as the battery supply.
Table 6. Crystal Electrical Characteristics
Note: 1. (Externally supplied if using the SO8 or PSDIP8 package)
2. Load capacitors are integrated within the M41T56. Circuit board layout considerations for the 32.768 kHz crystal of minimum t race
lengths and isolation from RF generating signals should be taken into account.
STMicroelectronics recommends the KDS DT-38 Tuning Fork Type quartz crystal for industrial temperature operations.
KDS can be contacted at 913-491-6825 or http://www.kdsj.co.jp for further information on this crystal type.
All SNAPHAT battery/crystal tops meet these specifications.
