www.maxim-ic.com GENERAL DESCRIPTION The DS1670 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 DS1670 is established through a simple 3-wire interface. 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 DS1670 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.
