Add To BomMCP79400-I/SN General Description
The MCP79400 general purpose I2CTM Compatible real-time clock/calendar (RTCC) is highly integrated with memory and advanced features normally found in higher priced devices. These features include a battery switchover circuit for backup power, a timestamp to log power failures and digital trimming for accuracy. Using a low-cost 32,768 kHz crystal or other clock source, time is tracked in either a 12-hour 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 multifunction open drain output can be programmed as an Alarm Out or as a Clock Out that supports 4 selectable frequencies. In addition to the SRAM memory, there a unique ID in a locked section of EEPROM that can be unlocked and programmed by the end user.
Features
- VCC Min = 1.8V
- Icc < 5 µA Typical Dynamic Current
- VBAT Min = 1.3V
- Ibat < 700nA Typical Timekeeping & SRAM Retention Current
- VCC to VBAT (power lost)
- VBAT to VCC (power restored)
- Dual alarms with single Interrupt Output that operates on VCC or VBAT
- Clock Out frequencies of 32.768, 8.192 & 4.096 KHz and 1 Hz
- 1 ppm is approximately 86 milliseconds/day
- Factory standard or custom ID programming available
