MCP79511-I/MS

The MCP79511-I/MS is a low-power SPI Real-Time Clock/Calendar (RTCC) 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, non-volatile memory for safe data storage and several enhanced features that support system requirements. Along with a 32,768kHz crystal, this RTCC tracks time using several internal registers and then communicates the data over a 5MHz SPI bus that is fast enough to support a programmable millisecond alarm.

• Hours, minutes, seconds, hundredth of seconds, day of week, month, year, leap year
• Crystal oscillator requires external 32768kHz tuning fork crystal and load capacitors
• 1Hz, 4.096kHz, 8.192kHz, 32.768kHz Clock out function
• 2 Programmable alarms
• Programmable open drain output - Alarm or interrupt
• On-chip digital trimming/calibration - ±255PPM range in 1PPM steps
• Automatic battery switchover with timestamp
• Dual configurable alarms with a 0.01s count on one alarm
• Digital trimming range from -255 to + 255ppm in 1ppm steps
• EEPROM has 8-byte/page with block sector write protection
• Factory standard MAC address programming or custom ID
