The MCP79401T-I/SN is a Real Time Clock (RTC) device from Microchip Technology Inc., which combines a highly accurate and configurable timekeeping module with EEPROM memory capable of data retention for up to 10 years even when powered down. It is an ideal device to replace expensive mechanical hardware clocking and timing components in applications where downtime must be kept to a minimum. This device can be used in a variety of settings, including clocks, watches, vending machines, gaming systems, or any other application that requires reliable, accurate timekeeping.

The MCP79401T-I/SN is a low-power timekeeping device with an integrated Real-Time Clock (RTC) and a full-featured digital clock generator. It contains a 32-bit RTC, digital clock counter with six selectable clock dividers, and can be programmed to drive the external clock with selectable frequency outputs, from 32.768 kHz to 1 Hz. The device also supports both 4 and 6 wire clock connection configurations.

The MCP79401T-I/SN also has an integrated ultra-low power EEPROM capable of storing data over multiple power cycles and extended periods of time. The built-in random access memory (RAM) is also volatile and non-volatile and is used to store data while the device is in operation or in an inactive state. The EEPROM allows information to be retained even when the module is not powered or when its power source is disrupted. This means the module can retain its settings or data even after a power failure.

The MCP79401T-I/SN also has a backup battery feature which allows the device to maintain working settings and data even when not powered externally. This can be used to keep the time and settings stored in the module, thus preventing the need to reprogram the device when power is restored. The device also includes a wakeup timer and alarm feature that can be used to alert the user when time-specific events occur.

The MCP79401T-I/SN is a low power, highly accurate timekeeping device ideal for applications which require accurate timing and reliability even when external power sources are not available. With its integrated EEPROM and backup battery it can be used in a wide variety of settings, from simple clocks and watches to more complex gaming systems and vending machines.
