MCP7940N-I/MS Description

Short technical summary and product information.

The Microchip Technology MCP7940N-I/MS is an integrated circuit functioning as a Clock/Calendar with an I2C interface. It operates within a voltage range of 1.3V to 5.5V and supports features such as alarm functions, leap year calculation, and square wave output. The device also includes 64B of SRAM for data storage.

 

Designed for surface mounting, this IC comes in an 8-MSOP package, with an alternative designation of 8-TSSOP, 8-MSOP (0.118", 3.00mm Width). It operates reliably across a temperature range of -40°C to 85°C. The typical current consumption is 1.2µA at 3.3V, making it suitable for low-power applications. The time format can be displayed as HH:MM:SS in either 12 or 24-hour format, and the date format is YY-MM-DD-dd.

 

This Clock/Calendar IC is ideal for applications requiring accurate timekeeping and calendar functions. Its features like alarm and leap year support make it versatile for various embedded systems. The compact 8-MSOP package and low current draw are beneficial for space-constrained and power-sensitive designs.
