M41ST85YMH6E

The M41ST85YMH6E Real Time Clock (RTC) is a low-cost, low-power, highly accurate clock generator module that is used in a variety of applications, including industrial, banking, transportation, communications, and medical.

This unique device uses an integrated CMOS microcontroller, an external crystal oscillator, and an external battery for long-term accuracy. The integrated CMOS microcontroller supports both an alarm function and a traditional alarm register, and the external crystal oscillator is temperature compensated so that the device can remain accurate even in extreme temperatures.

The M41ST85YMH6E Real Time Clock includes a self-contained oscillator, power-on reset functionality, and maintains 50nA (at 25 degrees C) of current draw from the battery. The device is also offered in a variety of packages to suit a variety of applications, such as the 5x5mm QFN package, which is ideal for space-constrained designs.

At the heart of the M41ST85YMH6E RTC is an oscillator circuit that uses an external crystal to maintain a steady and highly accurate frequency. This circuit is precisely tuned to within +50ppm, ensuring that the output remains accurate over time even in harsh environments. The low-power consumption of the oscillator also ensures that the device can run for extended periods of time on a single-cell battery.

The M41ST85YMH6E RTC also includes a high-precision voltage reference, which enables the device to generate an accurate and reliable output voltage. This voltage is used to power the integrated microcontroller, which is capable of accepting commands from a host processor and performing various tasks, such as setting alarms, enabling interrupts, and controlling the frequency of output signals.

In addition, the M41ST85YMH6E RTC also includes a power-on reset functionality, which can detect an absence of power and, depending on the settings, will reset the device itself or trigger an interrupt that can be used to alert the host processor. This is useful in applications where accuracy is especially important or where there is a risk of power loss.

The M41ST85YMH6E Real Time Clock is a versatile and cost-effective solution for a variety of applications that require accurate timing and external power-on reset capabilities. Its low-power consumption, high accuracy and long-term battery life make it an ideal choice for industrial, banking, transportation, communications, and medical applications, among others.
