The MCP79522T-I/MN is a low-power 32-bit Real Time Clock (RTC) module designed by Microchip Technology Inc. This RTC module is specifically designed to operate from a 3V lithium battery and is housed in a 10-pin surface-mount package. The MCP79522T-I/MN RTC module combines a small package size, on-board EEPROM, and extremely low current consumption with high precision clock accuracy and reliability.

The MCP79522T-I/MN RTC module is used in a variety of applications, such as automotive and industrial products, home and factory automation, medical systems, gaming systems, and navigation and surveillance applications. The module is ideal for applications that require high precision timing and might be located in harsh environments. Its advanced new features make it convenient to use and increase its accuracy and robustness.

The MCP79522T-I/MN RTC module combines precision, high-reliability, low power operation, a small package size, and an on-board EEPROM for real time clock and application storage. The module also features an 8-channel programmable interrupt system with programmable levels and pulse lengths, an on-board trickle charge circuit for battery backup, a programmable time-of-day alarm, and a programmable configure function for controlling the internal oscillator, counter and RAM.

The MCP79522T-I/MN RTC module features a 32-bit counter with sub-second resolution and a programmable frequency of 1, 2, 4, 8, 16, 32, 64 and 128 Hz. The module also provides an on-board temperature sensor that can detect temperature changes and allow the device to compensate for temperature-induced drift. The integrated memory management controller can store a maximum of 224 8-bit data registers in the data RAM and a single 32-bit or 4-byte value in the real time clock register.

The MCP79522T-I/MN also incorporates a built-in power fail detection circuit. This circuit detects the loss of power and maintains the contents of the internal registers and data RAM in the event of power loss. Each register and data RAM is also protected from inadvertent writing or reading by the memory protection circuitry. This feature ensures that the MCP79522T-I/MN RTC module can maintain its accurate timekeeping even with frequent power cycles or in the presence of electrical noise.

The MCP79522T-I/MN Real Time Clock (RTC) module is an ideal solution for low-power, accurate, and reliable timekeeping in automotive, industrial, and home automation applications. The module’s small size and low power consumption allow for use in a variety of applications. The on-board EEPROM and on-board temperature sensor ensure that the module remains accurate and reliable even in harsh environments. Finally, the built-in power fail detection circuit enables the device to maintain its accurate timekeeping even during frequent power cycles or noise. As such, the MCP79522T-I/MN RTC module is an ideal choice for reliable, accurate, low-power timekeeping.
