Fonctionnalités et applications
The MCP79520-I/MS is a low-power Real-Time Clock/ Calendar (RTCC) that uses digital trimming compensation for an accurate clock/calendar, an interrupt output to support alarms and events, a power sense circuit that automatically switches to the backup supply, nonvolatile memory for safe data storage and several enhanced features that support system requirements.

This device is fully accessible through the serial interface, while VCC is between 1.8V and 3.6V, but can operate down to 1.3 V through the backup supply connected to the VBAT input for timekeeping and SRAM retention only.

Features:

  • Low Power Operation-VCC Min = 1.8 V-Icc < 5 µA Typical Standby Current
  • Low Backup Power-VBAT Min = 1.3 V-Ibat < 700nA Typical Timekeeping & SRAM Retention Current
  • Automatic Battery Switchover with Timestamp-VCC to VBAT(VCC Lost)-VBAT to VCC (VCC Restored)
  • Dual configurable alarms with a 0.01 sec count on one alarm-IRQ (VCC or VBAT)
  • Clock Out frequencies: 32.768, 8.192 & 4.096 KHz and 1 Hz
  • Digital Trimming Range from -255 to + 255 ppm in 1 ppm steps-Adjusts up to 22 seconds/day
  • EEPROM as 8 Bytes/Page with Block Sector write protection-Protect:None, 1/4, 1/2 or all of array
  • Factory standard MAC address programming or custom ID available
