MCP7940N-I/SN Description


MCP7940N-I/SN developed by Microchip Technology is a type of battery-backed I2C Real-Time Clock/Calendar (RTCC) with SRAM. It is specifically designed to track time using internal counters for hours, minutes, seconds, days, months, years, and days of the week. It supports I2C communications up to 400 kHz to ensure usage and configuration. Frequency variance caused by crystal tolerance and temperature can be adjusted based on on-chip digital trimming.



MCP7940N-I/SN Features


Oscillator for 32.768 kHz crystals

Operating voltage range of 1.8V to 5.5V

64-byte battery-backed SRAM

Two-wire serial interface, I2C compatible

Low typical timekeeping current
