M41ST87WSS6F ST Real-Time Clock | 20-SSOP | I2C, 64B SRAM

Product Overview

The M41ST87WSS6F is a low-power, serial real-time clock (RTC) with 64 bytes of SRAM from STMicroelectronics. It integrates a 32.768 kHz quartz crystal and provides timekeeping functions (seconds, minutes, hours, day, date, month, year) with automatic leap year compensation. The device communicates via an I2C interface and operates over a wide voltage range of 2.7V to 5.5V. Housed in a compact 20-pin SSOP package, it is ideal for space-constrained applications requiring accurate time stamping and data logging.
