RTC Minimizes Current Consumption

Fri, 04/02/2010 - 5:17am
DS1341Maxim Integrated Products (NASDAQ: MXIM) expands its RTC (real-time clock) product line with the DS1341. This RTC integrates an AGC (automatic gain control) circuit for dynamic drive-current adjustment to ensure that the device consumes the least amount of current required for operation. Additionally, it supports high-ESR crystals to give system designers greater flexibility in crystal selection. This combination of power savings and a wider selection of crystals makes the DS1341 well suited for medical, point-of-sale, automotive, and portable applications.

Address and data for this device is accessed through an I2C serial interface. Other features include two time-of-day alarms, two interrupt outputs, a programmable square-wave 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 also includes an input for synchronization, thus allowing the timekeeping accuracy to be based on an external clock source.

The DS1341 is available in a RoHS-compliant, lead-free, 8-pin microSOP package. It is fully specified over the -40 degrees Celsius to +85 degrees Celsius extended temperature range. Prices start at $0.94 (1000-up, FOB USA).
