## Description

The ST M41ST85YMH6 is a Serial Real-Time Clock (RTC) and NVRAM Supervisor manufactured by STMicroelectronics. This component features 512 bits of memory, organized as 64 x 8 bits, for storing critical timekeeping data and non-volatile RAM.

Designed for flexibility, the M41ST85YMH6 supports a supply voltage range of 3.0V to 5.0V. Its input/output voltage tolerance is within -0.3V to VCC +0.3V. The device is specified for a storage temperature range of -40°C to 85°C.

This RTC IC is housed in a Surface Mount SOIC package, making it suitable for integration into various electronic designs where space is a consideration. The maximum power dissipation is rated at 1W, and the output current is limited to 20mA.

Absolute maximum ratings include lead solder temperatures of up to 260°C for lead-free finishes and 240°C for standard SnPb finishes, each for 10 seconds. It is important to note that negative undershoots below -0.3V are not permitted in Battery Back-up mode, and wave soldering SOIC packages should be avoided to prevent damage to SNAPHAT sockets.
