DS1341 / DS1342 Low-Current I²C RTCs

Analog Devices DS134x Low-Current I²C Real-Time Clock (RTC) for high-ESR crystals is a timekeeping device that provides an extremely low standby current, permitting longer life from a power supply. The RTC supports high-ESR crystals, broadening the pool of usable crystals for the devices. The DS134x is accessed through an I²C serial interface and features two time-of-day alarms, two interrupt outputs, a programmable square-wave output, and a serial bus timeout mechanism. The clock / calendar of this Analog Devices module provides seconds, minutes, hours, day, date, month, and year information. The date at the end of the month is automatically adjusted for months with fewer than 31 days, including corrections for leap year. The clock operates in either 24hr or 12hr format with an AM/PM indicator.

Control and Automation Solutions - HVAC

Heating, Ventilation, and Air Conditioning (HVACs) are systems and technology responsible for the heating, ventilation, and air conditioning in buildings. HVAC systems regulate comfort (temperature and humidity), energy efficiency, and air quality. Analog Devices Inc. offers a wide range of devices to provide the correct solution for your HVAC application.

Real Time Clocks (RTC)

Analog Devices Inc. Real-time Clocks (RTCs) are offered in a wide range of low-power, highly accurate, small packages, and MEMs-based ICs. RTC ICs measure time, even when the power of the main device is off, so an auxiliary battery or supercapacitor are required. Power consumption is a key factor in most RTC designs, but accuracy and small package size are also important. The latest RTC ICs reduce package pin count by supporting a serial interface.
