MCP7940N-I/MS Frequently Asked Questions (FAQ)
-
The MCP7940N-I/MS can support clock frequencies up to 32 kHz.
-
The MCP7940N-I/MS automatically accounts for leap years, so no additional programming is required.
-
Yes, the MCP7940N-I/MS has a battery input pin (VBAT) that allows it to maintain the clock and calendar information even when the main power supply is absent.
-
The internal oscillator on the MCP7940N-I/MS has an accuracy of ±10 ppm over the operating temperature range.
-
While the MCP7940N-I/MS has a relatively high accuracy internal oscillator, it may not be suitable for applications that require extremely high accuracy timekeeping. In such cases, an external crystal oscillator may be required.
