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.
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.
