产品概述

The MCP79410-I/MS is a general purpose I²C™ compatible Real-Time Clock/Calendar (RTCC) is highly integrated with non-volatile memory. This features a battery switchover circuit for backup power, a timestamp to log power failures and digital trimming for accuracy. Using a 32.768kHz crystal or other clock source, time is tracked in either a 12 or 24-hour format with an AM/PM indicator and timing to the second, minute, hour, day of the week, day, month and year. As an interrupt or wakeup signal, a multi-function open drain output can be programmed as an alarm out or as a clock out that supports 4 selectable frequencies. In addition, non-volatile memory is included along with an unique ID in a locked section of EEPROM that can be unlocked and programmed by the end user.
  • Leap year compensated to 2399
  • On-chip digital trimming/calibration - 1PPM resolution, ±129PPM range
  • Dual programmable alarms
  • Versatile output pin - Clock output with selectable frequency
  • Power-fail time-stamp - time logged on switchover to and from battery backup
  • 2-wire serial interface
  • 64-byte battery-backed SRAM
  • 1kb EEPROM Memory
  • 64-bit protected EEPROM area - robust write unlock sequence
  • Low typical timekeeping current
  • Automatic switchover to battery backup
  • Programmable charge current
  • Programmable safety charge timers
  • Preconditioning of deeply depleted cells
  • Automatic end-of-charge control
  • Charge status output for direct LED drive
  • Automatic power-down when input power removed
