Portable System Controller

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

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 V_CCO, CEOL, and

CEOH pins. The backup energy source used to power

the RTC is also used to retain RAM data in the

absence of V_CCthrough the V_CCOpin. The chip-

enable outputs to RAM (CEOL and CEOH) are

controlled during power transients to prevent data

corruption.
