DESCRIPTION

The Portable System Controller is a circuit which incorporates many of the functions necessary for low

power portable products integrated into one chip. The DS1673 provides a Real Time Clock, NV RAM

controller, microprocessor monitor, and a 3-channel, 8-bit analog-to-digital converter. Communication

with the DS1673 is established through a simple 3-wire interface.

The Real Time Clock (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.
