M41ST87WMX6TR ST RTC & NVRAM Supervisor | 28-SO | I2C, 64B SRAM

Product Overview

The M41ST87WMX6TR is a highly integrated real-time clock (RTC) and NVRAM supervisor from STMicroelectronics, designed for applications requiring precise timekeeping and non-volatile memory retention. Housed in a 28-pin SOIC package, this device combines a 64-byte battery-backed SRAM, a 32.768 kHz crystal oscillator, and a power-fail detection circuit. It operates over a wide voltage range of 2.7V to 5.5V and provides I2C interface for communication. The M41ST87WMX6TR is ideal for industrial, automotive, and telecom systems where reliable time stamping and data retention are critical.
