DS1673  
Portable System Controller  
www.maxim-ic.com  
GENERAL DESCRIPTION  
FEATURES  
The DS1673 portable system controller is a circuit  
that incorporates many of the functions necessary for  
low-power portable products integrated into one chip.  
The device provides a real-time clock (RTC), NV  
RAM controller, microprocessor monitor, and a  
3-channel, 8-bit analog-to-digital converter (ADC).  
Communication with the DS1673 is established  
through a simple 3-wire interface.  
Cꢀ Provides Real-Time Clock  
Counts Seconds, Minutes, Hours, Date of the  
Month, Month, Day of the Week, and Year  
with Leap Year Compensation Valid Up to  
2100  
Power-Control Circuitry Supports System  
Power-On from Day/Time Alarm  
Cꢀ Microprocessor Monitor  
Halts Microprocessor During Power Fail  
Automatically Restarts Microprocessor after  
Power Failure  
The RTC provides seconds, minutes, hours, day,  
date, month, and year information with leap year  
compensation. The RTC also provides an alarm  
interrupt. This interrupt works when the DS1673 is  
powered by the system power supply or when in  
battery-backup operation, so the alarm can be used to  
wake up a system that is powered down.  
Monitors Pushbutton for External Override  
Halts and Resets an Out-of-Control  
Microprocessor  
Cꢀ NV RAM Control  
Automatic Battery Backup and Write Protection  
to External SRAM  
Automatic backup and write protection of an external  
SRAM is provided through the VCCO, CEOL, and  
CEOH pins. The backup energy source used to power  
the RTC is also used to retain RAM data in the  
absence of VCC through the VCCO pin. The chip-  
enable outputs to RAM (CEOL and CEOH) are  
controlled during power transients to prevent data  
corruption.
