M4T28-BR12SH1 Typical application Circuitry

The M4T28-BR12SH1 is a SNAPHAT® battery and crystal unit, produced by STMicroelectronics. This compact unit serves to maintain the real-time clock, calendar, and RAM data in non-volatile storage when the main power supply is interrupted or turned off.
Notable features of the M4T28-BR12SH1 include:

- Battery: A non-rechargeable lithium cell that provides backup power supply.

- Crystal: It contains a 32.768 KHz quartz crystal which ensures precise timekeeping.

- SNAPHAT® housing: This unique removable battery and crystal package helps maintain high-accuracy timekeeping.

- Compatibility: It is made to work with real-time clock ICs from STMicroelectronics.

The M4T28-BR12SH1 finds its application in various fields where time keeping and data storage in the event of power loss is essential. These can include telecommunication systems, data logging systems, industrial machines, and other electronic devices that require real-time clocks.

An example of how to connect the M4T28-BR12SH1 in a typical application with an ST M48T86 real-time clock chip is as follows:

1. Battery and Crystal Connection: The M4T28-BR12SH1 attaches directly to the top of the M48T86 real-time clock IC. Ensure the SNAPHAT® package is correctly aligned with the IC's battery and crystal pins.

2. Backup Power Supply (Vbat): Once the M4T28-BR12SH1 is attached, it provides backup power (via Pin 24 on the M48T86) and crystal control (via Pins 2 and 20 on the M48T86) directly to the M48T86 IC.

When using the M4T28-BR12SH1, there are a few considerations:

- Attachment and Removal: Care should be taken when attaching and removing the SNAPHAT® battery and crystal package to avoid damage.

- Battery Life: It's crucial to consider the battery life, as the lithium battery in the package is non-rechargeable and must be replaced when depleted.

- Temperature: The operating temperature range of the device should be adhered to for optimal performance and longevity. In conclusion, the M4T28-BR12SH1 is an innovative solution for maintaining real-time clock operation and non-volatile data storage in the event of a power loss. It is appropriate for a variety of applications due to its adaptability and interoperability with real-time clock ICs from STMicroelectronics.
