General Description

The DS1341/DS1342 low-current real-time clocks (RTCs) are timekeeping devices that provide an extremely low standby current, which permits longer life from a power supply.

The DS1341/DS1342 support high-ESR crystals, which broaden the pool of usable crystals for the devices.

The DS1341 uses a 6pF crystal, while the DS1342 uses a 12.5pF crystal.

Overview

19-4998; Rev 0; 10/09 Low-Current I2C RTCs for High-ESR Crystals General.

Key Features

  • include two time-of-day alarms, two interrupt outputs, a programmable squarewave output, and a serial bus timeout mechanism. The clock/calendar 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. The DS1341/DS1342 also include an input for synchronization. When a referenc.
