BQ4845YS-A4NTR General Description

The BQ4845YS-A4NTR is one member of the BQ4845 family which designed as one kind of parallel RTC with CPU supervisor that integrates a time-of-day clock, a 100-year calendar, and a CPU supervisor in a 28-pin SOIC or DIP.It provides direct connections for a 32.768KHz quartz crystal and a 3V backup battery and it contains a temperature-compensated reference and comparator circuit that monitors the status of its voltage supply.

Features of the BQ4845YS-A4NTR are:(1)real-time clock counts seconds through years in BCD format;(2)on-chip battery-backup switchover circuit with nonvolatile control for external SRAM;(3)less than 500nA of clock operation current in backup mode;(4)microprocessor reset valid to VCC=VSS;(5)indepen-dent watchdog timer with a programmable time-out period;(6)power-fail interrupt warning;(7)programmable clock alarm interrupt active in battery-backup mode;(8)programmable periodic interrupt;(9)battery-low warning.

The absolute maximum ratings of the BQ4845YS-A4NTR can be summarized as:(1)DC voltage applied on VCC relative to VSS:-0.3 to 7.0 V;(2)DC voltage applied on any pin excluding VCC relative to VSS:-0.3 to 7.0 V;(3)operating temperature:0 to +70°C(commercial) or -40 to +85°C(industrial);(4)storage temperature:-55 to +125 °C;(5)temperature under bias:-40 to +85 °C;(6)soldering temperature:+260 °C for 10 seconds.If you want to know more inform-ation such as the electrical characteristics about the BQ4845YS-A4NTR,please download the datasheet in www.seekic.com or www.chinaicmart.com .
