I needed a reliable component to maintain my equipment’s real-time clock during power outages, and the M4T32-BR12SH6 module delivered exactly what I needed. It’s not a standalone timer chip—as some might misunderstand—but a backup power module that snaps onto existing SOIC-28 ICs to keep the clock running smoothly. Installation was a breeze with the SNAPHAT® design—no soldering required! The resin-sealed housing handled the high temperatures in my factory environment (-40°C to 85°C) without any issues. I’ve had zero downtime since installing it, and the 32.768 kHz crystal ensures pinpoint timing accuracy. Highly recommend for anyone needing uninterrupted RTC functionality in servers, IoT devices, or industrial systems

Bought this to upgrade an older car’s clock circuit, and it worked flawlessly! The module snapped directly onto the original IC using SNAPHAT® technology, providing seamless backup power without modifying the wiring. The description clearly states it’s a power continuity solution, not a standalone timer, so there were no surprises. The 3V operation and 32.768 kHz oscillator kept the dashboard clock accurate even during battery disconnections. The rugged, sealed design is ideal for automotive environments—no worries about dust or moisture. Shipping was fast, and the seller included a detailed datasheet for compatibility checks. A must-have for retrofitting vintage vehicles or industrial gear

This thing is not really what it says it is. It is not a clock/timer chip. This is a package with a crystal and a lithium battery. I had to consult the data sheet to figure it out. I measured the battery terminals and saw 3.3 V.The only really useful purpose for this is to be soldered over the ACTUAL timer chip; this device supplies backup power for the clock (and the battery is not intended to be replaceable), and a crystal for the oscillator.
