DESCRIPTION
Description
OVERVIEW
Product Overview
The MCP7940NT-I/SN is an I2C real-time clock/calendar device from Microchip that provides timekeeping information such as hours, minutes, seconds, date, month and year, with a clock circuit that can be backed up by a battery or supercapacitor. It integrates a small SRAM so that the clock and key data can be maintained when main power is removed. It is typically used in electronic equipment that needs to log timestamps or trigger actions based on time, communicating with the host controller over the I2C bus with few pins. The device also offers a programmable clock output that can serve as a reference clock or periodic interrupt for the system. Refer to the original datasheet for exact register map, accuracy and electrical specifications.
APPLICATIONS
Applications
- Used in data logging equipment to add timestamps to collected data.
- Used in home appliances and office equipment for timer and schedule functions.
- Used in security devices to record the date and time of events.
- Used in industrial instruments to maintain system time after power loss.
FEATURES AND BENEFITS
Features and Benefits
- Provides timekeeping information including hours, minutes, seconds, date, month and year.
- Supports battery or supercapacitor backup to maintain timekeeping when main power is removed.
- I2C interface communicates with the host controller using few pins.
- Integrated SRAM can retain key data under backup power.
- Programmable clock output can serve as a reference clock or interrupt source.
ADDITIONAL DETAILS
Additional Details
When purchasing, confirm the suffix and package correspond to SOIC-8, and verify options such as integrated SRAM and programmable output. Different suffixes may map to different interface or feature configurations, so avoid mixing. Request the original datasheet from the supplier to confirm register and electrical specifications before ordering.
Verify product details against the manufacturer datasheet before purchase.
