Microchip MCP79401-I/SN Alarm RTC IC Year/Month/Week/Date/Hr/Min/Sec 12Hr / 24Hr I2C 1.8 V to 5.5 SOIC-8
The MCP79401-I/SN is a low-power Real-time Clock (RTC) uses digital timing compensation for an accurate clock/calendar, a programmable output control for versatility, a power sense circuit that automatically switches to the backup supply and non-volatile memory for data storage. Using a 32.768kHz crystal, it tracks time using several internal registers. For communication, the MCP7940X uses the I²C� bus. The clock/calendar automatically adjusts for months with fewer than 31 days, including corrections for leap years. The clock operates in either the 24-hour or 12-hour format with an AM/PM indicator and settable alarm(s) to the second, minute, hour, day of the week, date or month. Along with the battery-backed SRAM memory, a 64-bit protected EEPROM space is available for unique ID or MAC address to be programmed at the factory or by the end user.
- On-chip digital trimming/calibration - 1ppm Resolution
- Dual alarm with single output
- Programmable open-drain output control - CLKOUT with 4 selectable frequencies and alarm output
- 64-byte SRAM, battery backed
- Automatic VCC switchover to VBAT backup supply
- Power-fail time-stamp for battery switchover
- Low-power CMOS technology
- 1 Million erase/write cycles for unique ID
- 64-bit Unique ID - User or factory programmable and protected EEPROM
